Introduction to the VMEbus Standard

1

VMEbus is an architecture for connecting and interfacing microcomputer based modules. Originally defined by Motorola, Mostek and Signetics corporations, it is now a recognized international standard:

IEEE/ANSI STD 1014-1987

IEC 821 and 297

The abbreviation VME stands for VERSA Module Eurocard. When the first VMEbus specification was under development, the Eurocard format for printed circuit boards and racks was well established in Europe, with many sources for this hardware.

VMEbus Standard Definitions

The VMEbus standard defines the mechanical and functional characteristics of the interconnection. It does not ensure the operating compatibility of VMEbus modules.

There are many options to the VMEbus that may cause two VMEbus modules, both of which adhere to the standard, to be incompatible with each other.

VMEbus features and options include:

H 16, 24, and 32 bit address bus options

H 8, 16, and 32 bit data bus options

H up to seven interrupt levels

H a master-slave architecture

H multiple masters

H two heights of modules and racks

H one or two backplanes

H high data transfer rate between modules

H asynchronous data transfers - no clocks required to transfer data

H non-multiplexed bus - separate address and data pins.

Mechanical Structure

The VMEbus mechanical structure consists of backplanes, boards or modules, slots and racks.

H two board and rack heights, designated as 3U and 6U

H up to 21 modules per rack

H slots on 0.8 inch centers

H maximum bus signal length of 19.37 inches (500 mm)

1-2

Backplanes

All VME racks contain the J1 (upper) backplane. This backplane allows 16 and 24 bit addresses, and 8 and 16 bit data transfers. 3U (5.25 inch) high racks have only the J1 backplane and support only 3U size boards. 3U modules connect only to the J1 backplane.

6U (10.5 inch) high racks have the J1 backplane and, optionally, the J2 (lower) backplane.

The J2 backplane provides additional standard lines for 32 bit addressing, 32 bit data and additional DC power. The J2 backplane also has unused lines which many manufacturers use for other busses or I/O.

6U modules are more popular than 3U modules. Like 3U high modules, they connect to the J1 backplane. In addition, 6U modules may connect to the J2 backplane. 6U modules which use 32 bit addressing or data, must be in a rack with a J2 backplane.

The connector on a module which plugs into the J1 backplane is referred to as P1; the connector on a module which plugs into the J2 backplane is referred to as P2. Racks may have up to 21 slots. The VMEbus standard refers to the mechanical structure containing the backplane(s) and slots as a subrack.

H Functional Structure

The VMEbus contains numerous functional modules, only some of these are defined here. The VMEbus consists of four subbuses:

H Data Transfer Bus (DTB)

H Data Transfer Arbitration Bus

H Priority Interrupt Bus

H Utility Bus.

User’s Guide to Integration of 3rd Party VME Modules - December 1997 GFK-0448E

Data Transfer Bus (DTB)

The Data Transfer Bus contains 32 data bits and 32 address bits. Associated with an address is a six-bit Address Modifier (AM) code. The AM code indicates the type and size of the address. An address may be one of three types:

H Short: 16 address bits

H Standard: 24 address bits

H Extended: 32 address bits.

A bus timer function is active during each Data Transfer Cycle. The bus timer monitors the time consumed by the transfer and terminates the cycle if the time becomes unreasonably long. The bus timer is typically located in the module in slot 1 (also called the slot 1 controller).

Data Transfer Arbitration Bus

A functional module, the arbiter, determines which requesting module will be granted use of the DTB. This function is always located on the module in slot 1 (also called the

slot 1 controller).

Master modules initiate data transfer cycles. Slave modules receive data transfer requests and respond to them. A module may act as a master sometimes and as a slave at other times. Or it may be strictly a master or strictly a slave. Slave boards look like memory to the VMEbus.

Interrupt Priority Bus

The VMEbus standard defines up to seven interrupt priority levels. An interrupter asserts one of the interrupts lines - designated IRQ1 through IRQ7. An interrupt handler acknowledges the interrupt and takes some action based upon the interrupt.

Interrupt handlers are usually found on CPU-type modules.

Interrupts are acknowledged via a daisy chained IACK line. Because this line is daisy chained, interrupts cannot function if there is an empty slot (J1 connector) between the interrupt requestor and the interrupt handler.

Utility Bus

The Utility Bus contains power, ground, a system clock and signals for coordinating system reset, system failure and loss of power. Refer to VMEbus specifications for details see Appendix E).

Power Supplies

There is no VME standard for interconnection of power supplies and backplanes. Power supplies for VMEbus systems come in both Eurocard and open frame form factors.

Eurocard type supplies reside in the VME rack but do not have a direct backplane plug-in connection. They are instead cabled from the back of the supply to terminals on the rear of the backplane(s). Open frame supplies mount external to the rack, and are also cabled to the rear of the VME backplane(s).

VME-based systems can have high power requirements. Power supplies of 400 watts output per rack are not unusual. Most VME-based systems require cooling fans, often

GFK-0448E Chapter 1 Introduction to the VMEbus Standard 1-3

for operation even at room (ambient) temperatures. A Rack Fan Assembly (catalog number IC697ACC721 for 120 VAC power source or IC697ACC724 for 240 VAC power source) is available from GE Fanuc for those applications which require additional cooling. These fans are available in fan trays which rack mount directly below the VME rack. Systems that include only GE Fanuc products do not need additional cooling over the specified temperature range, 0

The VMEbus signals SYSRESET and ACFAIL are used for generating system reset at power up and for providing advance warning of power failure. These signals are provided either directly from the power supply, or from a separate power monitor module in the rack.

The optional SYSFAIL signal is user-defined in its causes and system response.

Guidelines for Selection of

2

3rd Party VME Modules

section level 1 1 figure bi level 1 table_big level 1

This chapter describes the guidelines for successful integration of 3rd party VME modules in the Series 90 t-70 PLC. VME is an international standard which defines physical board size, electrical and busing structure using standard DIN connectors for the interconnect of 8, 16, and 32 bit microprocessors.

Successful integration of 3rd party VME modules in the Series 90 t-70 PLC is guided by the following criteria:

H The module selected must comply with the VMEbus Specification REV C.1 (October

1985). No earlier version of this specification may be used.

H The module selected must be compatible with the particular characteristics of the

Industrialized VMEbus (VME-I) as implemented on the GE Fanuc Series 90-70 PLC.

H The module selected must not interfere with the normal operation of the Series

90-70 PLC system.

H Bus slaves rather than bus masters are preferred, as they are easier to integrate into the Series 90-70 PLC system.

H No more than three 3rd Party VME modules may be placed in a standard Series

90-70 PLC rack.

H 3rd Party VME modules cannot be used in a remote Series 90-70 rack controlled by a

Series 90-70 Remote I/O Scanner module.

Also refer to the checklist in Appendix D.

Environmental Considerations

In selecting a VME module for operation with the Series 90-70 PLC system, it is necessary to pay close attention to the environmental ratings of the module since these individual module ratings may limit overall system rating. The specifications which need to be determined are listed below along with the corresponding Series 90-70 PLC ratings for each specification. For more detailed information on product agency approvals, standards, and general specifications for Series 90-70 products refer to data sheet GFK-0867.

In selecting VME modules, consideration must be given to maintaining acceptable component temperature when the VME module has other modules on either side of it, each dissipating up to 17 watts. The VME module itself should not exceed 17 Watts if this specification is to be met.

Use of Fans for Temperature Rating

A characteristic of the Series 90-70 PLC Industrialized VMEbus (VME-I), is that low power technology is employed in order to achieve the full temperature rating for Series

90-70 PLC modules without the use of fans. When selecting VME modules from other vendors for use in the Series 90-70 PLC, it must be determined whether fans are required to achieve the specified VME module temperature rating in a Series 90-70 PLC installation. If fans are needed, an optional Rack Fan Assembly is available from GE

Fanuc.

Power Supply

The VMEbus includes both a +5 volt bus and " 12 volt busses; however, not all Series

90-70 PLC power supplies have a " 12 volt output, and the output current rating of the

+5 volt bus depends on the model of Series 90-70 PLC power supply chosen. Also, a

Two Rack Power Cable is available which allows two racks to be operated from a single

Series 90-70 PLC power supply. The following limitations apply to power supplies:

H Only modules which use +5 volts may be used in the rack (second rack) without the power supply (the " 12 volt busses are not carried in the Two Rack Power Cable).

H Current rating of the +5 volt bus in the second rack (without power supply) is limited to 5.2 amperes or less.

H None of the Series 90-70 PLC power supplies fully support the +5 volt standby bus.

The 55 Watt supply has no connection between the +5 volt standby backplane line and the +5 volt power bus. If +5 volt standby power is required by a VME module, a method must be supplied by the user to route power to that backplane line if the 55 watt power supply is being used. The other supplies connect the +5 volt standby power to the +5 volt bus during operation, but are electrically isolated from it following power down.

H Series 90-70 AC power supplies will ride through a 1 cycle loss of AC input power without system interruption. If the loss exceeds 1 cycle, the ACFAIL signal will be asserted and a shutdown procedure will begin after a 5 millisecond holdup time of backplane power busses.

Note

The maximum current required for any single VME module is restricted to 4.5 amperes or less (worst case) on the +5 volt bus (3 amps recommended maximum) due to the J1 backplane connector capacity. If additional capacity is required some modules allow a J2 connector to carry additional current to the module.

Power supply ratings for the Series 90-70 PLC power supplies are listed below.

Backplane Voltage Isolation

Series 90-70 PLC Discrete and Analog I/O modules (called Model 70 I/O) provide 1500V opto-isolation between user (field) connections and the Series 90-70 PLC backplane to prevent system misoperation or damage in the event of transients which occur on user wiring to the modules. In selecting VME modules, preference should be given to those modules which provide such isolation.

Note

If no isolation from PLC backplane to field connections is provided, system noise immunity may be compromised.

Mechanical Restrictions

The standard Series 90-70 PLC racks (IC697CHS750/790/791) accommodate modules on

1.6

I centers (double VME width). VME modules which are single width (0.8I) require a cover plate for the unused half of the rack opening to keep out foreign objects. A cover plate made of non-conductive material is available from GE Fanuc. DO NOT use metal cover plates since they can short to the back of GE Fanuc I/O modules (which have electrically hot field wiring) as they are removed from or inserted into the rack.

VME Integrator racks (IC697CHS782/783) are available that have 17 slots and will accept

3rd Party VME modules in each slot which require 0.8

I spacing. These racks also accept

Series 90-70 modules which require two of these VME slots (1.6

I spacing).

Certain VME modules have more than one PC board, each with a connection to the backplane. Modules having this type of construction in which the PC boards are on single-slot (0.8

I) spacing CANNOT be used with standard racks since the standard Series

90-70 PLC backplane has slots (card guides and connectors) on 1.6

I centers only. These

VME modules can be used when installed in a VME Integrator rack which has slots on

0.8

I centers.

The Series 90-70 PLC rack accepts double-high modules designated as 6U in the VMEbus

Compatible Products Directory in the Compatibility column. No direct provision is made for single high VME modules indicated by a 3U designation. However, such modules may be used if a commercially available 6U faceplate adapter is attached to the 3U module to allow securing it to the rack rails. Such faceplate adapters are often supplied by the vendor of the 3U high board.

GFK-0448E Chapter 2 Guidelines for Selection of 3rd Party VME Modules

VME Backplanes

The VME standard specifies two backplanes, designated J1 and J2. The Series 90-70 PLC system only contains the J1 backplane; there is no J2 backplane. If the J2 backplane is required, you must purchase a VME Option Kit (IC697ACC715) which contains the hardware and rail necessary to install a J2 backplane but does not contain a J2 backplane.

This kit also contains mounting standoffs to allow rear-mounted racks to have a J2 backplane added. The J2 backplane, which can be different widths, must be obtained from a VME vendor.

Note

None of the standard Series 90-70 PLC Power Supplies make direct connection to the J2 backplane. However, the VME Integrator rack does provide for this connection through a cable.

If power is required on the J2 backplane, it must be connected by the user. One method is to use a modified Two Rack Power cable, IC697CBL700, normally used for second rack operation from one supply. The use of this cable allows +5 VDC power from a connector at the left end of the J1 backplane to be routed to the J2 backplane to make the required connection. If this technique is used, the ability to power a second rack from the power supply in this rack is lost. To use the cable in this manner, the connector at one end must be removed and adapted for connection to the selected J2 backplane. The

+5 volts and common are each carried on several wires in this cable. It is necessary to maintain the parallel connection of these conductors to achieve the required current carrying capacity of the cable. Two wires in this cable, which carry the ACFAIL and

SYSRESET signals, must be disconnected at the power supply end of the cable.

J2 Backplane

Sometimes a J2 backplane is required in a Series 90-70 PLC system that includes 3rd party (non-GE Fanuc) modules. Since GE Fanuc modules do not use the J2 backplane, the selection of a J2 backplane depends on the requirements of the third party modules in the system.

J2 backplanes are available in many different lengths (typically 2 to 21 slots) and with different types of power pick-up connectors. Also, some backplanes pre-buss and terminate row b while allowing rows a and c to be user defined. Some backplanes allow totally user defined pinouts. Some backplanes include on-board termination, and some require off-board termination.

The J2 backplane can be used in many different ways by 3rd party modules. Sometimes it is required only to provide parallel power paths to the module (in addition to J1), and sometimes J2 is needed only to make user interface connections to the module. If 3rd party modules are communicating with each other using 32 bit addressing, then the J2 backplane is used for address bits 24 through 31 (and/or data bits 17 through 31). To determine the correct backplane option to use, the requirements of all the third party modules in the system must be taken into consideration. The manufacturers of the 3rd party modules may need to be consulted to determine the best backplane choice for your application.

J2 backplanes are available from many different vendors. A fairly complete list is available in the VITA Compatible Products Directory. Two vendors that are listed in this directory who have large selections of backplane products are listed on the following page.

Series 90-70 PLC Support of Multi-Master Subsystems

The Series 90-70 PLC system is based on the VME standard.

A Series 90-70 PLC system always requires a Series 90-70 PLC CPU to be located in slot 1 of rack 0 which performs the slot 1 controller functions. It is also a bus master, but only one Series 90-70 PLC CPU can be located in the same Series 90-70 PLC system.

A VME master is a device which is granted temporary control of the bus by the slot 1 controller. A bus master can initiate read and write functions to any supported VME address. The VME bus can support multiple master subsystems. Devices which are capable of master operation but which operate on;y as slaves are not considered masters in the context of this discussion.

Third party VME masters located in the same rack as the Series 90-70 PLC CPU may communicate directly with other 3rd party VME devices in a Series 90-70 PLC system which are in the main rack or in expansion racks without the PLC CPU application participating in the transaction.

Programmable Coprocessor Modules (PCMs) having revision J, or later, can also act as

VME master in any Series 90-70 PLC rack.


2-5

2

Restrictions:

H Third party VME masters are not supported in racks with Bus Receiver Modules

(BRMs), or Remote I/O Scanner modules, nor by Series 90-70 CPUs not supporting this feature (CPUs with catalog numbers earlier than IC697CPU731P,

IC697CPU732D, IC697CPU771M, IC697CPU772D, IC697CPU781F, or

IC697CPU782F). All versions of CPUs with catalog numbers IC697CPU780,

IC697CPU788, IC697CPU789, IC697CPM914, and IC697CPM924 (CPM924 will be available in early 1994) all provide multi-master support.

H The Series 90-70 PLC does not have a dual ported memory with VME addresses and does not have facilities to allow association of VME interrupts with user applications and therefore VME masters cannot initiate communications with the Series 90-70

PLC CPU except by using a common VME memory which might be a dual ported memory on the VME master.

H Other Series 90-70 PLC modules use ASIC chips and an unpublished proprietary messaging protocol to communicate with the Series 90-70 PLC CPU and direct communications with these modules from third party VME masters is not supported.

Categorization of Candidate Modules

VME modules are categorized in several ways. The first is by whether they are bus master modules or bus slave modules. Bus Master modules control the transfer of data between themselves and other modules on the VMEbus. Bus slaves do not control the bus; typically, they have an interface to the VMEbus which can be addressed (data read or written) by a VMEbus master, for example, the Series 90-70 PLC CPU.

The second way of categorizing VME modules is by the number of address and data bits they support. The VMEbus Compatible Products Directory refers to these as the module’s address and data width specification. Both categorization methods are discussed below.

Bus Master Modules

To control data transfers, bus master modules control the bus itself and can potentially interfere with the Series 90-70 CPU which also is attempting to use that bus for communication among modules on the bus. The use of foreign bus master modules is restricted so that improper interaction with the Series 90-70 CPU does not occur. These restrictions include:

H Must use a Series 90-70 CPU that allows foreign VME master support (see the above discussion on Series 90-70 PLC Support of Multi-Master Subsystems).

H The Series 90-70 CPU is always the slot 1 controller. If a 3rd party bus master contains bus arbitration or clock circuitry, that circuitry must be disabled.

H Bus requests must be made only on Bus Request lines BR2 or BR3. Bus Request lines

BR1 and BR0 are reserved by the Series 90-70 PLC. The priority of these lines in the

Series 90-70 system is BR1 highest, followed by BR0, BR3, and BR2.

H Upon receipt of a Bus Clear (BCLEAR) signal, bus masters must release the bus within 40 microseconds (maximum).

H Bus masters must not use block move cycles.

H All bus access in the Series 90-70 CPU is limited to 8 or 16 data bits and 16 or 24 address bits. 3rd party modules may communicate with each other using up to 32 data bits and 32 address bits if a J2 backplane is used.


2

H Bus masters must never service interrupts IRQ5, IRQ6, or IRQ7. Refer to Interrupts on page 3-5 for more information on interrupts.

H Bus masters cannot be used in expansion racks.

H There is no dual-ported RAM memory on the Series 90-70 PLC CPU directly accessible from the VMEbus. Even with the Series 90-70 CPUs listed above, a foreign

VME bus master cannot initiate a read or write to the Series 90-70 CPU.

Bus Slave Modules

Slave VME modules often have a shared RAM interface through which the VME module data is exchanged with the VMEbus master. Flow of data between the slave module and the VMEbus is controlled by the bus master module. Certain slave modules may have interrupt capability which, if used, must be done with care and in such a way as not to interfere with the Series 90-70 PLC system (for details, refer to Interrupts on page 3-5).

Currently, VME modules may interrupt only each other, not Series 90-70 modules, Series 90-70

PLC I/O modules, or the Series 90-70 CPU.

Bus Width

VME modules transfer data in three widths: 8 bits, 16 bits, and 32 bits. Some modules support all three, some only two (typically 8 and 16 bits) and some only one. The Series

90-70 PLC supports data widths of 8 bits and 16 bits. It does not support a data width of 32

bits. Typically, only modules which transfer data in 8-bit or 16-bit widths are compatible with the Series 90-70 PLC.

VME module support up to three address widths: 16 bits, 24 bits and 32 bits. These are referred to, respectively, as Short (16 bits), Standard (24 bits) and Extended (32 bits). The

Series 90-70 PLC supports address widths of 16 bits and 24 bits. It does not support 32 bit

address widths. If your module requires a 32-bit address you may still be able to use it by either wiring the 25th through 32nd address bits or by installing a J2 backplane and driving the 25th through 32nd address lines external to the VME module. See Appendix

D, Why Do Restrictions Exist?

for additional information.

Auxiliary VME Rack Capability

Sometimes functionality is required that can only be met with the use of a commercially available VMEbus extender or Reflective Memory module to interconnect a second, auxiliary VME rack to the Series 90-70 PLC. Such extenders have boards in both the

Series 90-70 PLC rack and the auxiliary VME rack and are connected through a cable.

When using these bus extenders, they must be set up to allow the two racks to communicate via a shared RAM interface on one of the boards (NOT as an electrical extension of the VMEbus). This shared RAM technique provides a means to structure the complete user-specific system in the auxiliary rack including bus masters, interrupts, etc. as desired with no direct effect on the Series 90-70 PLC operation. The Series 90-70

PLC Bus Transmitter Module and Bus Receiver Module do NOT provide this full capability as the Bus Receiver Module does not arbitrate or respect arbitration for bus mastership.

VME System Overview

The address on a VMEbus consists of two parts: an address modifier (AM) code and address bits A0 through A31. All boards in a VME system are configured to respond to one or more AM codes and an address range. The AM code can be considered an extension of the address bus. The AM code consists of 6 bits and is used to select the type of VME access (that is, the number of address bits used). There are 64 possible AM codes which are divided into three categories:

H Defined

H Reserved

H User-Defined

The access types and address length for defined AM codes are given in Table 3-1.

The GE Fanuc Series 90-70 modules use three of the defined codes:

H 29H Short non-privileged

H 2DH Short supervisory

H 39H Standard non-privileged

There are no reserved AM codes used in the Series 90-70 PLC. The Series 90-70 PLC system also uses all 16 of the user-defined AM codes, 10H through 1FH. These AM codes are discussed later in this chapter.

Third Party Module Address Allocation

Address allocation for 3rd party modules is driven by three items: AM code, GE Fanuc

Series 90-70 module location, and 3rd party module location.

Address assignments for 3rd party modules are typically setup with jumpers. The addresses assigned to 3rd party modules must not overlap installed GE Fanuc Series

90-70 modules or other 3rd party modules.

GFK-0448E 3-1

GE Fanuc Series 90-70 Module Address Allocation

Addresses for the GE Fanuc Series 90-70 modules are allocated on a rack and slot basis.

Address allocation is also based on the VME access type. The address allocation for GE

Fanuc modules in the Series 90-70 system are given in the following tables. This information is necessary to determine what unused address space can be allocated to

3rd party modules.

The short access address allocation given in Table 3-2 is the same for each rack. Rack selection is discussed in Expansion Rack Considerations on page 3-3.

The standard access address allocation given in Table 3-3 is allocated on a rack/slot basis.

Standard access address space allocated to a rack cannot be used for a 3rd party module located in another rack. For example, standard access address space allocated to a slot in rack 1 cannot be used by 3rd party modules in another rack.

GE Fanuc Series 90-70 modules plugged into slots indicated in these tables will respond to the listed address. Therefore, care must be taken to assure that a 3rd party module will not respond to an address allocated to a slot which contains a GE Fanuc Series 90-70 module. For example, a PCM residing in rack 0 slot 3 will respond to the following address:

H address range 1800H through 1FFFH for AM code 29H and 2DH;

H address range 020000H through 03FFFFH for AM code 39H

[ All addresses shown are in Hexadecimal format

] Rack 0 is the CPU rack.

Note that GE Fanuc Series 90-70 modules will not respond to the user defined address space listed in the tables. For short access AM codes, 29H and 2DH, address range 5000H through FFFFH is user definable for each rack. For example, two 3rd party modules responding to AM code 29H and address 5000H through 7000H will not conflict if they reside in different racks.

The user definable address space for standard access AM code 39H is 100000H through

7FFFFFH. This address space is available in rack 0 only. For example, a 3rd party module responding to address 100000H through 200000H must reside in rack 0.

An AM code not used by GE Fanuc Series 90-70 modules is 3DH. Therefore, 3rd party modules configured to respond only to standard access AM code 3DH and address range 000000H through FFFFFFH will never interfere with GE Fanuc Series 90-70 modules. 3rd party modules configured to respond to 3DH must reside in the main rack.

Chapter 3 Configuration of VME Modules 3-3

3

Modules with large address space requirements are permitted in the Series 90-70 PLC system. They will simply occupy the address allocation for more than one slot. Care must be taken to assure that no GE Fanuc Series 90-70 modules reside in slots that a 3rd party module’s address covers. For example, consider a module requiring 1Mbyte of standard access AM code 39H address space. This module can be located in rack 1 and configured to respond to address E00000H through EFFFFFH. In this case, no Series

90-70 modules may reside in rack 1. Refer to Appendix C for configuration examples.

Expansion Rack Considerations

Expansion racks are addressed differently for short access AM codes then they are for standard access AM codes. For short access the rack is addressed by the AM code. Tables

3-4 and 3-5 give the AM codes that the module must be configured to respond to and that must be programmed in the function block AM parameter (see Chapter 5,

Programming Considerations) to select an expansion rack for short access. For standard access (AM code 39H) the address alone selects the expansion rack and slot (refer to

Table 3-3).

For example, consider a Series 90-70 PLC system containing two 3rd party modules; one configured to respond to short access AM code 2DH address 3000H through 4FFFH resides in rack 5, and one which responds to standard access AM code 39H address

EC0000H through EFFFFFH residing in rack 1. Note that GE Fanuc developed Series

90-70 modules must not be in slots 6, 7, 8, and 9 in rack 5, and slots 8 and 9 in rack 1.

The following function block parameters must be programmed to address the module residing in rack 5 configured for short access AM code 2DH:

H AM code 12H

H desired address within range 3000H through 4FFFH

The following function block parameters must be programmed to address the module residing in rack 1 configured for standard access AM code 39H:

H AM code 39H

H desired address within range EC0000H through EFFFFFH

Bus Width Compatibility

The Series 90-70 VME backplane uses the J1 connector only; therefore the maximum number of address and data bits the backplane can support is:

H 24 address bits and

H 16 data bits

With this restriction the Series 90-70 PLC system can support modules which use:

H 16 address and 16 or 8 data bits and

H 24 address and 16 or 8 data bits

VMEbus Clock and System Functions

The Series 90-70 PLC system provides the VMEbus clock and bus controller functions.

VME modules which include this capability should have them disabled. The Series 90-70

PLC power supply generates the necessary power sequencing signals such as ACFAIL and SYSRESET. VME modules providing these functions must have them disabled.

VME modules must not assert these signals under any condition.

GFK-0448E Chapter 3 Configuration of VME Modules 3-5

VME Interrupts

The Series 90-70 PLC CPU handles VME interrupts IRQ5, IRQ6, and IRQ7. 3rd party

VME modules must not service these interrupts. Third party VME modules may interrupt each other on IRQ1, IRQ2, IRQ3, or IRQ4. Third party VME modules may interrupt the Series 90-70 PLC CPU on IRQ6. See Interrupting the PLC CPU (page 3-21) for more information on interrupting the PLC CPU on IRQ6.

If a 3rd Party VME module is physically located to the left of a module that can generate interrupts, then the 3rd Party VME module must pass the VME interrupt acknowledge daisy chain to the slot on the right. If the 3rd Party VME module does not pass the VME interrupt acknowledge daisy chain to the right, then it must be physically located to the right of all modules that can generate VME interrupts.

3rd Party

Module

IRQ1

3rd Party

Module

Figure 3-1. VME Interrupts between 3rd Party Modules

When an interrupt is used between 3rd party VME modules, only interrupts IRQ1 through IRQ4 can be used, and one of the modules must be the interrupt handler. This avoids interference with the processing of interrupts by the Series 90-70 PLC CPU.

Special backplane jumpers must be installed in those slots which have VME modules that either generate or handle these interrupts (IRQ1 – IRQ4).

A list of these jumpers and their functions can be found in Table F-1 in Appendix F.


Slot Location Considerations for VME Modules

Use the following guidelines to determine the slot location of VME modules in a Series

90-70 PLC system. The Series 90-70 PLC system has two types of racks, standard racks and VME Integrator racks.

Standard Series 90-70 Racks and VME Integrator racks

To avoid potential problems with 3rd party modules which may not pass the VME daisy chain signals, the following guidelines are suggested.

H All Series 90-70 PLC modules should occupy lower numbered (that is, the leftmost) slots in the rack. All 3rd party VME modules must be installed to the right of the

Series 90-70 PLC modules.

H There must not be any unused slots between Series 90-70 modules in the rack.

Similarly, there must not be any unused slots between VME modules which must interrupt each other. And there must not be any unused slots between the PLC CPU and a VME module which handles interrupts. If an unused slot between modules is required (for example, to accommodate an over-wide module) a connector which daisy chains the interrupt signals must be used.

VME Integrator Racks

H VME modules can be installed in any module slot (2PL - 9PL and 12PL - 19PL).

H Series 90-70 modules, when installed in a VME Integrator Rack, can only occupy slots 2PL - 9PL) since they require two VME slots. Jumpers on the backplane are configurable to allow the SYSFAIL signal to be enabled or disabled; to allow the

LWORD signal to be inactive; to configure IRQ1/ - IRQ4/ signals for VME slots 12PL to 19PL; and to configure the Bus Grant signals for VME slots 12PL to 19PL.

Note

3rd Party VME modules CANNOT be installed in a remote I/O system controlled by the Series 90-70 Remote I/O Scanner. The 3rd Party VME modules cannot communicate with the Series 90-70 CPU from a remote system since the VME instructions cannot be executed over the Genius

I/O communications link.

VME Module Configuration

When any features beyond the standard VME read and write function blocks are being used in conjunction with a 3rd Party VME module, the the module must be specified in the Logicmaster 90-70 or CIMPLICITY Control I/O configuration. There are six mutually exclusive configuration modes for 3rd Party VME modules. Table 3-6 summarizes each of the configuration modes.

Table 3-6. Modes of Configuration for 3rd Party VME Modules

Mode Description

None The configuration of the module is used only as a placeholder.

Interrupt Only The module will interrupt the PLC CPU to trigger logic execution.

Bus Interface The module’s memory is configured to be accessed via the VME config read and VME config write function blocks. In addition, the module may interrupt the PLC CPU to trigger logic execution.

Full Mail For use with the GE Fanuc Plug & Play PC Coprocessor.

Reduced Mail This mode is not yet supported by the PLC CPU.

I/O Scan For use with the Series 90-70 Thermocouple Input module, catalog number HE697THM160.

If your particular application does not require any of the 3rd Party VME features provided by the PLC CPU or it is just using the standard VME read and VME write function blocks, then configuring the module in the rack/slot configuration is not required. Even if the configuration of the module is not required, you may wish to include the module in the configuration for documentation or configuration error checking purposes. Use the NONE configuration mode in this case. A 3rd party VME module with configuration mode NONE acts as a placeholder within the rack/slot configuration.

If your application does require use of a 3rd Party VME feature provided by the PLC

CPU, then you are required to specify the module in the I/O configuration. Table 3-7 summarizes which configuration modes can be used with each of the particular PLC

CPU features for 3rd Party VME Modules.

Configuring 3rd Party Modules with Logicmaster 90-70

Note

For information on configuration using CIMPLICITY Control programming software, refer to the CIMPLICITY Control online help.

Note that the information in this paragraph applies to both Logicmaster 90-70 and CIMPLICITY

Control programming software. There is one selection available for foreign VME modules in the I/O configuration software: 3RD PTY VME which is found under the VME menu.

When 3RD PTY VME is selected, six modes of configuration are available (which are described above). If a 3rd Party VME module is placed to the left of a module that can generate interrupts, then it is assumed that the 3rd Party VME module passes the VME interrupt acknowledge daisy chain to the slot on the right. If the module does not pass the VME interrupt acknowledge daisy chain, then it must be placed to the right of all modules that can generate VME interrupts. The configuration software will flag an error if an empty slot is located to the left of a module which can generate interrupts.

Configuring a VME Module

To configure a VME module on the I/O Configuration Rack screen:

1.

Move the cursor to the desired rack and slot location. The slot may be either unconfigured or previously configured.

Note

When configuring the VME module in a VME Integrator Rack, the half-slot screen for a particular slot is displayed. This allows you to configure the half slots of that slot. The remainder of the configuration process is the same for the VME Integrator Rack as it is for a standard I/O rack.

2.

Press VME (F7) and then VME (F1) from the I/O Configuration Rack screen to display a list of available modules.

3.

Position the cursor on the 3RD PARTY VME module, and press the Enter key to display the detail screen for that module.


3

Selecting the Configuration Mode

The configuration mode specifies how the module will be accessed. The configuration mode is selected in the Configuration Mode field on the module detail screen.

1.

To select a different configuration mode, move the cursor to the Configuration Mode field and repeatedly press the Tab key until the desired mode is displayed on the screen. Then, press the Enter key.

2.

Configure the module. Then, press Rack (Shift-F1) or the Escape key to return to the rack display.

Interrupting the PLC CPU

Third party VME Modules may interrupt the Series 90-70 PLC CPU on IRQ6 to trigger the execution of logic in the Series 90-70 application program. Each interrupt can be used to trigger one LD interrupt block and up to the maximum number of standalone programs. CIMPLICITY Control (version 2.00 or higher) is required to use this feature.

Also, CPU version 7.10 or higher is required.

3rd Party

Modules

GFK-0448E

Figure 3-2. VME Interrupts from 3rd Party Modules

Module Requirements

Third Party VME modules being used to interrupt the Series 90-70 PLC CPU must meet the following requirements.

IRQ6

Third Party VME modules may only use IRQ6 to interrupt the PLC CPU. The module must release IRQ6 as soon as the PLC CPU completes the VME interrupt acknowledge cycle. If the module does not release IRQ6 immediately upon the acknowledge, then the PLC CPU will interpret this as a subsequent interrupt request and be forced to service the VME interrupt again. If this condition persists, the recurring interrupts could starve all of the other processes running in the PLC CPU and eventually cause the PLC system watchdog timer to expire. An expired watchdog timer will send the CPU to

STOP/HALT mode.

Interrupt ID

When the 3rd Party VME module generates a VME interrupt, it must present an interrupt id during the interrupt acknowledge cycle. The id that the module presents is a byte value which must be either the binary coded decimal representation slot:rack

(based on its physical location in the system) or a value between 0F0 and 0FEH. For example, if the VME module is placed in slot 5 of rack 1, its default interrupt id would be

51H (slot 5 rack 1). Alternatively, the module could use the value FBH as long as no other module in the system will use that value. It is acceptable for the interrupt id to be configurable either with hardware jumpers or with a VME write from within the application program.

Dual Port Memory

Third Party VME modules being used to interrupt the Series 90-70 PLC CPU may optionally have dual port memory. This memory can be accessed by using the VME read or VME write function blocks. The VME address for the dual port memory must fit the allocation requirements described in pages 3-1 through 3-5.

Module Configuration

Third party VME modules that will be used to interrupt the PLC CPU must be specified in the CIMPLICITY Control rack/slot configuration. To configure a third party VME module, chose Add Module from the Edit–>Module Operations menu, select the VME tab from the Module Catalog, and then select 3rd Party VME. Third party VME modules may be placed in the main rack or in expansion racks. When using the Integrator’s rack,

3rd Party VME modules used to interrupt the PLC CPU may only reside in a slot A; they may not be used in a slot B. Once the 3rd Party VME module is added, a parameters dialog with the following three parameters will appear.

Configuration Mode

There are six mutually exclusive configuration modes for third party VME modules. The two valid configuration modes for interrupting the PLC CPU are Interrupt Only and

Bus Interface

. Although VME interrupts can be generated by 3rd party modules using other configuration modes (such as Full Mail and I/O Scan), those interrupts are used strictly for high priority mail messages. They cannot be used to trigger the execution of a block or program.

Interrupt

This parameter is used to mask the interrupt from this 3rd Party VME module. When this parameter is set to Enabled, the PLC CPU will process the interrupt from this module and schedule the associated block and programs for execution. When this parameter is set to

Disabled, the PLC CPU will process the interrupt from this module but will not schedule the associated block or programs for execution. When the interrupt is Disabled in the rack/slot configuration, it cannot be unmasked via Service Request Function Block #17.

Interrupt ID (Hex)

Each VME module in the system (3rd Party or otherwise) must have a unique interrupt identifier. The interrupt identifier is a byte hexadecimal value which identifies the module driving the interrupt line and must be entered on the configuration screen. The

3rd Party VME module may either use its physical location (slot:rack) or an unused value between F0 and FE hexadecimal as its interrupt id. For example, if a VME module is configured in slot 3 of rack 0, its default interrupt id would be 30H (slot 3 rack 0).

Alternatively, the module could use the value F5H as long as no other module in the system is using that value. (CIMPLICITY Control programming software configuration function will prevent the user from selecting the same interrupt id for more than one module.) Only one interrupt id is allowed for each module. The interrupt id that the module in this rack and slot is using must match the interrupt id entered as this configuration parameter.

Associating Interrupt with Logic

In addition to configuring the 3rd Party VME module in the rack/slot configuration within CIMPLICITY Control, the association between the interrupt and the block and/or program(s) that are to be executed needs to be specified within the resource editor.

CIMPLICITY Control provides a set of pre-defined names which correspond to all of the possible interrupt ids that a 3rd Party VME module could use. Each of these names can be used as the SINGLE input for an IEC task. The form for these names is VME_xx,


where xx is the interrupt id (for example, VME_30, VME_F5). The VME_xx name form is only for use with interrupts from 3rd party VME modules. (Series 90-70 discrete and analog interrupts are named by their corresponding %I and %AI references.)

A single interrupt source (that is, one VME_xx name) can be used as the trigger to multiple IEC tasks with different priorities. However, a single interrupt source can only trigger one LD interrupt block. The VME_xx variable is not a real physical variable that can be accessed and tested by a program; it is simply a name to satisfy the SINGLE input to the IEC task. For more information about defining IEC tasks, refer to the CIMPLICITY

Control online help.

Frequency and Queuing

The Series 90-70 PLC system allows VME interrupts from discrete, analog, and 3rd Party modules to trigger LD interrupt blocks and standalone programs in the PLC. The queuing and frequency of the 3rd Party interrupts are subject to the same rules that apply to the discrete and analog interrupts. (See Interrupt Handling in Chapter 2 in the

Series 90-70 Programmable Controller Reference Manual, GFK-0265G, and later revisions for more information.)

Dynamic Masking of the Interrupt

The Series 90-70 PLC CPU provides a service to dynamically mask and unmask interrupts from 3rd Party VME modules from within the application logic. This operation is analogous to how interrupts from Series 90-70 discrete and analog modules are masked and unmasked via Service Request Function Block #17.

To mask or unmask an interrupt from a 3rd Party VME module, the application logic will pass VME_3PY_INT_ID (17 decimal, 11H) as the memory type and the interrupt id as the offset to SVC_REQ #17. When the interrupt is not masked, the PLC CPU will process the interrupt and schedule the associated block and programs for execution.

When the interrupt is masked, the PLC CPU will process the interrupt but will not schedule the associated block or programs for execution. When the interrupt is Disabled in the rack/slot configuration, it cannot be unmasked via Service Request Function Block

#17. For more information on Service Request Function Block #17, see GFK-0265, the

Series 90-70 Programmable Controller Reference Manual.

Installation of VME Modules

4


Cooling for Optimum Operation

As indicated previously, if any selected VME modules require forced air for cooling, the installation of fans to ensure that those cooling requirements are met must be done by the user. Additionally, certain industrial applications may require the presence of loss-of-fan detection. Rack Fan Assemblies (IC697ACC721 and IC697ACC724) are available from GE Fanuc as an option for those applications requiring additional cooling.

Rack Standoffs for J2 Backplane Requirements

When specifying components for those applications requiring the J2 backplane, be aware that many commercially available J2 backplanes have wirewrap pins that extend beyond the Series 90-70 PLC backplane. Subsequent use of the J2 backplane will require that the panel-mount version of the rack be mounted on standoffs attached to the panel to ensure clearance between the wirewrap pins and the panel. Refer to Table 2-3, which lists the items in the VME option kit for mounting a J2 backplane. The front-mount version may use standard rack mounting techniques.

Grounding Requirements

VME modules used in a Series 90-70 PLC rack must use proper grounding practices.

VME modules often use the module front as the ground point with the top and bottom screws which secure the module to the rack as the ground connection. The user should therefore be certain that the mounting screws are securely attached, and the module should not be removed from the rack unless external connections to the module are first removed.

Warning

If the external connections are not removed as described above, potentially hazardous voltages may exist on the module. Additionally, no grounding point exists after the mounting screws have been disconnected.

Module Location in Racks

All VME modules installed in a standard Series 90-70 PLC rack should be physically located with consideration for empty slots as described under Slot Location

Considerations for VME modules

in the previous chapter on page 3-5. Location of VME modules in a VME Integrator Rack are also described on that page.

This chapter describes the programming functions which allow the Series 90-70 PLC to communicate with 3rd party VME modules. For additional information on Series 90-70

PLC programming, refer to GFK-0263, Logicmaster t 90 Programming Software User’s

Manual and GFK-0265, Logicmaster t 90 Programming Software Reference Manual, or

CIMPLICITY Control online help (as applicable to your programming software).

Programming Functions for Communicating with 3rd Party VME Modules

A group of functions (instructions) is available with Logicmaster 90 software to allow the

Series 90-70 PLC CPU to communicate with VME modules obtained from 3rd Party manufacturers. These functions include:

H VME READ (VMERD)

H VME WRITE (VMEWRT)

H VME READ/MODIFY/WRITE (VMERMW)

H VME TEST AND SET (VMETST)

H VME CONFIG READ (VME_CFG_RD)

H VME CONFIG WRITE (VME_CFG_WRT)

H SWAP

Byte Significance Convention

When transferring data between the Series 90-70 PLC and a 3rd party VME module, proper consideration must be given to byte significance convention. The Series 90-70

PLC uses the Intel convention for storing word data in bytes, that is, the least significant bits (LSB) of a word are stored in the even byte. Many VME modules follow the

Motorola

convention of storing the least significant bits of a word in the odd byte.

The VMEbus access circuitry of the Series 90-70 PLC keeps byte addresses straight, that is, byte address 1 is the same storage location whether accessed from the Series 90-70

PLC or a Motorola convention CPU. However, because of the difference in byte significance, transfers of word and multiword data, for example, 16 bit integers (INT,

UINT), 32 bit integers (DINT) or floating point (REAL) numbers, will require adjustment on transfers to or from Motorola convention modules.

In these cases, the two bytes in each word must be swapped, either before or after the transfer (the SWAP function is available for this purpose). In addition, for multiword data items, the words must be swapped end-for-end on a word basis. For example, a

64-bit real number transferred to the Series 90-70 PLC from a Motorola convention module must be byte swapped and word reversed, either before or after reading, as follows:

GFK-0448E

5-1

5

B1 B2 B3 B4 B5 B6 B7 B8

Character (ASCII) strings or BCD data require no adjustment since the Intel and

Motorola conventions for storage of character strings are identical.

VME READ (VMERD)

The VMERD function reads data from the dual-port RAM of VME modules located in the Series 90-70 PLC rack. Typically, these are not GE Fanuc modules, but may include some GE Fanuc modules, such as the Programmable Coprocessor Module (PCM). This function should be executed before the data is needed in the program.

This byte or word of data is combined (AND/OR) with the data mask MSK. Selection of AND or OR is made using the OP input. If byte data is specified, only the lower 8 bits of MSK are used. The result is then written back to the same VME address from which it was read.

VME TEST AND SET (VMETST)

The VMETST function handles semaphores located in the dual-port RAM of VME modules located in the Series 90-70 PLC rack. Typically, these are not GE Fanuc modules, but may include some GE Fanuc modules, such as the PCM. The VMETST function exchanges a boolean true (1) for the value currently at the semaphore location. If that value already was true, then the VMETST function does not acquire the semaphore. If the existing value was false, then the semaphore is set and the VMETST function has the semaphore and the use of the memory area it controls. The semaphore is cleared and ownership relinquished by using the VMEWRT function to write a 0 to the semaphore location.

VMETST function sets the Q output to true if the semaphore (false) was available and acquired. The VMETST function passes power flow to the right through its OK output whenever power is received and its operation is successful.

Example of VMETST Function

In the following example, the VMERD, VMEWRT, and VMETST functions are used to read data protected by a semaphore into the PLC.

When enabling input %M00047 is set true (elsewhere in the program), the VMETST function is executed to acquire the semaphore (semaphore VME address stored in

%R00041 and %R00042). When this is successful, coil %M00047 is reset and coil

%M00048 is set. When %M00048 is set, the VMERD function reads the data (20 words of data whose VME address is stored in %R00043 and %R00044; data read into %R00200 through %R00219). If the read is successful (if it is not - something is misprogrammed or broken), the VMEWRT function relinquishes the semaphore. Coil %M00048 is reset when the VMEWRT is successful. %M00049 is set to indicate to later logic that fresh data is now available.

If the semaphore was not available, VMERD and VMEWRT are not executed. The net effect is that the setting of %M00047 causes the PLC to check the semaphore each sweep until the semaphore is available. When it becomes available, the semaphore is acquired, the data is read and the semaphore is relinquished. No further action is taken until

%M00047 is set again.

VME_CFG_RD

Use the VME_CFG_RD function to read the configuration for a VME module. The

VME_CFG_RD function has five input parameters and three output parameters. When the function receives power, the data elements (N) are read from the VME bus at the location defined by rack (R), slot (S), and dual port offset (OFF). The data read is placed in output Q. The status of the operation is placed in the status word output (ST). The function has a length specification (LEN) of the maximum size of the output array.

If the function is completed successfully, ok is set ON; otherwise, it is set OFF. It is also set OFF when:

H The number of data elements (N) is greater than the length (LEN) specified.

H The rack/slot value (R and S) is out of range or is not a valid VME location.

H The most significant byte of the dual port offset (OFF) is not zero.

H The most significant byte of the dual port address plus the dual port offset is not zero.

H Read beyond the end of dual port memory.

H Specified rack/slot not configured for a Third-Party VME module in

VME_CFG_WRT

Use the VME_CONFIG_WRITE function to write the configuration to a VME module.

The VME_CFG_WRT function has six input parameters and two output parameters.

When the function receives power, the data elements (N) are written from the data array (IN) to the VME bus at the location defined by rack (R), slot (S), and dual port offset (OFF). The status of the operation is placed in the status word output (ST). The function has a length specification (LEN) of the maximum size of the output array.

If the function is completed successfully, ok is set ON; otherwise, it is set OFF. It is also set OFF when:

H The number of data elements (N) is greater than the length (LEN) specified.

H The rack/slot value (R and S) is out of range or is not a valid VME location.

H The most significant byte of the dual port offset (OFF) is not zero.

H The most significant byte of the dual port address plus the dual port offset is not zero.

H Read beyond the end of dual port memory.

H Specified rack/slot not configured for a Third-Party VME module in

Q:

The SWAP function is used to swap two bytes within a word, or two words within a double word. The necessity of doing this swap was described previously in Byte

Significance Convention at the beginning of this chapter. The SWAP can be performed over a wide range of memory by specifying a length greater than 1 for the function. If this is done, each word or double word of data within the specified length will be appropriately swapped.

The SWAP function has two inputs and two outputs:

specifies the location in PLC memory for the beginning reference for data to be swapped.


specifies the location in PLC memory where the swapped data will be stored.

When the SWAP function receives power flow, it performs the swap operations on each word or double word of data within the specified area. The results of the swap are stored to output Q. The SWAP function passes power to the right whenever power is received.

Example of SWAP Function

In the following example, when enabling input %I00001 goes true, two bytes located in word %I00033 through %I00048 are swapped. The result of the swap is stored in

%L00007. Unless an error occurs while swapping the bytes, output coil Q00001 will be set to true.

Why Do Restrictions Exist?

B

section level 1 1 figure_ap level 1 table_ap level 1

The body of this manual describes a number of restrictions and recommendations for adding 3rd party VME modules to the Series 90-70 PLC. This appendix describes the reasons for certain of these restrictions. This appendix is intended for use by those of you who want more information than is provided in the body of this manual.

Interrupts and a 3rd Party Interrupt Handler

If it is necessary to use interrupts 1 through 4, a 3rd party interrupt handler is required.

The 3rd party handler must be configured to handle interrupt requests IRQ1 through

IRQ4 only.

In the Series 90-70 PLC system IRQ1 through IRQ4 are used for slot identification.

Jumper locations are provided to disable slot identification and connect IRQ1 through

IRQ4 to the backplane. Therefore, when using 3rd party interrupt handlers, it is necessary to install jumpers on the backplane at the slots that contain the interrupt handler and 3rd party boards that will request interrupts.

A foreign interrupt handler becomes a bus master when servicing interrupts, therefore all foreign bus master restrictions apply.

AM Codes and Expansion Racks

The Series 90-70 VME bus is extended to expansion racks through the Bus Transmitter and Bus Receiver modules. During short access the Series 90-70 user defined AM codes,

10H through 1FH, are used by the Bus Transmitter Module to determine if the short access is directed towards the main or expansion racks. During a short access the Bus

Receiver Module uses the Series 90-70 user defined AM code to determine if its rack has been selected.

During standard access the Bus Transmitter Module and Bus Receiver Modules use the address to determine which rack the modules reside in. When a Bus Transmitter

Module receives an address allocated to an expansion rack it drives the VME bus in the main rack and transmits the address to the Bus Receiver Modules in the system. Any

Bus Receiver Module present will then respond to the VME access if the address is allocated to the rack it resides in.

Restrictions for AM Code 29H

During short access the Bus Receiver Module waits to receive the Series 90-70 defined

AM code for its rack. The Bus Receiver Module then converts the Series 90-70 defined

GFK-0448E

B-1

B

AM code to the corresponding short access AM code. After converting an AM code, the

Bus Receiver module takes control of the VME bus transferring control signals and data to and from its rack. For example, assume that you have programmed AM code 18H and address 4000H in a VME byte write function block. The Bus Transmitter Module will take control of the VME bus in the main rack and transmit AM code 18H and address

4000H. The Bus Receiver Module present in rack 7 will convert AM code 18H to 29H and transmit it, the control address, and data to the local bus in rack 7.

Restrictions for AM Code 39H

The user defined address 100000H through 7FFFFFH for AM code 39H is restricted to rack 0. This is due to the fact that the Bus Transmitter Module will not pass rack 0 allocated addresses to extended racks. If a Bus Transmitter Module is not present address 100000H through 0EFFFFFH is unused address space and can be allocated to 3rd party modules.

When a Bus Transmitter Module is present unused address space allocated to expansion racks cannot be assigned to 3rd party modules in the main rack. This restriction is due to the fact that the Bus Transmitter Module will always drive the backplane when an address allocated to an expansion rack is used. This occurs with or without the expansion rack present.

Unused address space in expansion racks must only be assigned to 3rd party modules located in that rack. This restriction is due to the Bus Receiver Module. The Bus

Receiver Module will only respond to addresses allocated to the rack it resides in.

Restrictions for AM Codes 0DH and 09H

It is possible to use extended addressing (32 bit address) in the main rack only. To use extended addressing you must pull the upper address bits A24 through A31, located on the P2 connector, to a known state. You can then program a VME access function block with the correct extended AM code and address. Extended access will not interfere with

Series 90-70 modules.

Restrictions for AM Code 2DH

Immediately after a power cycle or after Logicmaster 90 has downloaded a new configuration to the CPU, the Series 90-70 CPU will check for the presence of GE Fanuc modules in each available rack and slot. Using AM code 29H, the CPU will attempt to read the module “VME ID” bytes from each of the short address ranges listed in the table on page 3-2. If any data can be read successfully, indicating the presence of a module, then the CPU will set a diagnostic bit at offset address 1 using AM code 2DH.

When using a non-GE Fanuc module, the effect of such a write to the board should be carefully considered. If this could cause a problem, it is recommended that the module addressing be configured to respond in the “user defined” range as listed. Another alternative might be to disable the board response to AM code 2DH.

Configuration Examples

C


This appendix contains three examples of configuring 3rd party VME modules. These configuration examples include:

1.

Two examples of a single slot board in the main (CPU) rack;

2.

A 3rd party VME module in an expansion rack.

Example 1 - Single Slot Module Located in the Main Rack

The following assumptions are made:

A. The module can be configured as a D16/A16 or D16/A24.

B. The address and AM code are configurable.

The module will be configured for two different Series 90-70 configurations.

Example 1 - Configuration 1

For Configuration 1 the 3rd party module must be located in slot 6. The following address ranges are available:

Table C-3. Example 1 - Configuration 1 Available Address Range

AM Code

29H

2DH

39H

3DH

Address Range

3000H - FFFFH

3000H - FFFFH

080000H - 7FFFFFH

000000H - 7FFFFFH

The best address choice is AM code 3DH. With this configuration, the module will be out of the Series 90-70 address range. This allows for Series 90-70 module expansion without having to reconfigure the 3rd party module.

Example 1 - Configuration 2

For configuration 2, the 3rd party module must be located in slot 5. Without the Bus

Transmitter Module the following address ranges are available:

Table C-4. Example 1 - Configuration 2 Available Address Range

AM Code

29H

2DH

3DH

Address Range

2800H - FFFFH

2800H - FFFFH

080000H - 7FFFFFH

000000H - 7FFFFFH

The best address choice is AM code 3DH. As with the previous example, this will allow for Series 90-70 module expansion. If a Bus Transmitter Module will never be present in the system, then AM code 39H with address range 100000H through FFFFFFH will also allow for Series 90-70 module expansion within the main rack.

C-2 User’s Guide to Integration of 3rd Party VME Modules - December 1997 GFK-0448E

Example 2 - Single Slot Module Located in an Expansion Rack

In this example, a 3rd party module will be located in an expansion rack. It is assumed that the module’s AM code and address range are configurable. The module will be located in expansion rack 4 which has the following configuration:

Table C-5. Example 2 - Series 90-70 Expansion Rack Configuration

Slot

3

Module

IC697BEM711 - Bus Receiver Module

With this configuration the available address range is as shown in the following table.

As stated previously, AM code 3DH is not available in expansion racks.

Table C-6. Example 2 - Available Address Range

AM Code

29H

2DH

39H

Address Range

1800H - FFFFH

1800H - FFFFH

B20000H - BFFFFFH

The best choice for this configuration is to use either AM code 29H or 2DH and address range 5000H through FFFFH. This will allow for expansion within this rack without having to reconfigure the 3rd party VME module. When using a short access to address this module the AM code programmed must be 1BH for configured AM code 29H and

13H for configured AM code 2DH.

Quick Compatibility Checklist

D


GFK-0448E

This appendix provides a checklist to be used as a quick reference to help select Series

90-70 PLC compatible 3rd party VME modules. There may also be other factors which determine compatibility. Refer to the text in this manual for more detailed information. h The module must comply with VMEbus Specification Revision C.1.

h Series 90-70 CPUs that allow operation with foreign masters were available beginning with the first quarter of 1992. Catalog numbers of these CPUs are:

IC697CPU731P, IC697CPU732D, IC697CPU771M, and IC697CPU772D (or later revision of each model), and all newer CPU models. Previous revisions may not work properly when used with foreign masters.

h The Series 90-70 rack accommodates 6U modules; 3U modules require the use of adapter hardware or a 6U faceplate to support the smaller 3U module.

h The standard Series 90-70 rack has only a J1 backplane. To use modules with both P1 and P2 connectors you must add a J2 backplane to the Series 90-70 rack and provide the required power connections. No Series 90-70 module uses the J2 backplane.

h The standard Series 90-70 racks (catalog numbers IC697CHS750/790/791) provide card guides for every other VME slot. Multiple slot modules, or modules which have daughter boards can not plug into these racks without modification. The VME

Integrator racks (IC697CHS782/783) provide card guides and connectors for every

VME slot (17 slots).

h The module must be A24 (standard) or A16 (short) address compatible. Although the Series 90-70 PLC system does not support A32 (extended) bit addressing, such modules may be used if the upper 8 address bits (A24 through A31) are strapped to a fixed value.

h The module must be compatible with D16 (16 data bits) and D8 (8 data bits) data transfers. The Series 90-70 PLC system does not support D32 (32 data bits) data transfers. 16 bit data transfers are preferred.

h The module must respond to one or any combination of the following address modifier (AM) codes:

H 2DH, 29H Short Access

H 39H, 3DH Standard Access h Modules responding to AM code 3DH must reside in the main rack.

h The module must not respond to Series 90-70 defined AM codes 10H through 1FH.

h Modules requiring " 12VDC must reside in a rack powered by the GE Fanuc 100W

AC/DC, 90W 24 VDC or 90W 48 VDC power supply.

D-1

D

h Per connector current requirements for any VME module must not exceed 4.5A at 5

VDC and 1.5A at " 12 VDC at 25

°

C (77

°

F). The GE Fanuc power supplies provide:

H 55W AC/DC power supply: 11 amps of 5 volt DC power;

H 90W 24 VDC power supply: 18 amps of 5 volt DC power, 1.5 amps of +12 volt

DC power, and 1 amp of –12 volt DC power;

H 90W 48 VDC power supply: 18 amps of 5 volt DC power, 1.5 amps of +12 volt

DC power, and 1 amp of –12 volt DC power;

H 100W AC/DC power supply: 20 amps of 5 volt DC power, 2 amps of +12 volt DC power, and 1 amp of –12 volt DC power.

h Multi-board sets which have 0.8I centers will not fit in the standard Series 90-70 rack since the rack backplane connectors and card guides are on 1.6

I centers. To use these these types of modules requires the VME Integrator rack, which has connectors and card guides on 0.8

I centers.

h Cooling fans may be required for non GE Fanuc modules to meet the 0 to 60

°

C (32 to

140

°

F) operating temperature range of the Series 90-70 PLC. For applications requiring additional cooling, an optional rack fan assembly (IC697ACC721) is available.

h The range of addresses to which the module responds must be configurable to prevent overlap with those used by any Series 90-70 modules present in the system.

h All Bus Arb functions must be disabled at power-up.

h Modules must not assert the signals ACFAIL and SYSRESET. If they do, the system will not operate properly. If the module asserts SYSFAIL, it must do so only at power-up, and must drive SYSFAIL for no longer than one second.

h Masters must not use Address Only (ADO) cycles.

h The module must be able to recover from SYSFAIL which is asserted by the Series

90-70 CPU during power-up, and during I/O configuration.

h Modules must not generate block transfer cycles.

h VITA categorizes modules by address width, data width, data transfer type, and master/slave. Modules which are most likely to be integrated into the Series 90-70

PLC System are characterized by one or more of the following acronyms (the acronyms are explained in both the VITA catalog and the VMEbus Specification).

Figure F-1. VME Integrator Rack

Each rack configuration will accept one power supply in the leftmost module position, and either

1.

17 3rd Party VME modules

2.

9 Series 90-70 modules, or

3.

a combination of Series 90-70 and 3rd

Party VME modules.

Two racks can be interconnected to share a single power supply for applications having extended I/O requirements. A

Power Supply Extension Cable kit

(IC697CBL700) is available for such applications. There are also four power cube screw connections (+5V, +12V, –12V, 0V) on the backplane for use with a Series

90-70 power supply when used to supply power to an optional P2 backplane. These

connections are not intended for direct connection to a 3rd Party power supply.

The power supply capacity may limit the maximum number of modules in a rack. No more than three VME modules

can be used in a rack with Series 90-70 modules.

Each rack provides slot sensing for rack-type I/O modules designed for the

Series 90-70 PLC. No jumpers or DIP switches on the I/O modules are required for module addressing.

The flexibility of this rack to allow both 3rd party VME and Series 90-70 modules is accomplished through the use of jumpers on the backplane to configure slots. The

VME Integrator rack is factory configured to accept standard Series 90-70 modules.

Integration of 3rd party VME modules is done by moving these jumpers to different positions. The exact jumper configuration depends on the requirements of each 3rd

Party VME module.

Overall rack dimensions are:

height = 11.15 inches (283mm) width = 19 inches (483mm)

depth* = 7.25 inches (184mm).

*

Depth is 8.25 inches (209mm) with spacers in VME option kit installed.

Slots are 0.8 inch wide except the power supply slot which is 2.4 inches wide.

Rack Mounting

Racks are available for either rear (panel) or front (rack) mounting. Rack dimensions and installation information for each type or rack is shown in Figures F-2 and F-3 on the previous page. The rack must be mounted in the orientation shown in the figures.

Sufficient space must be left around the rack as shown to allow air flow for module cooling. A Rack Fan Assembly is available for installations requiring forced air cooling.

The mounting requirements (either front or rear mount) must be determined according to the application and the proper rack ordered. Refer to the illustrations on the previous page for mounting dimensions of these racks. Mounting flanges are an integral part of rack side panels and are installed at the factory.

I/O Connections

The VME Integrator racks accommodate two module types.

First, they accommodate rack-type Series

90-70 high-density I/O modules, which use a detachable field wiring terminal board.

Each I/O module will accept up to forty

AWG #14 (2.1 mm

2

) wires. The wire bundle is routed out the bottom of the terminal board cavity where a cleat is provided for a tie wrap to secure the bundle to the terminal board housing.

Second, they accommodate VME modules which may have varying methods of connecting to field devices.

Configuring a VME Integrator Rack

A series of jumper positions are located on the backplane near each slot. These jumpers provide for flexibility in the types of modules to be installed, either VME modules in single slots (0.8 inch spacing between centers) or Series 90-70 modules, which require two slots (1.6 inch spacing between centers).

Table F-1 shows the relationship of the slot numbers to the jumper numbers.

Configurable functions and signals are:

H select rack ID for multiple rack systems (Series 90-70 feature)

H configure SYSFAIL signal to be enabled or disabled (per slot)

H LWORD signal in slot 1 configurable to be inactive

H configure IRQ1/ - IRQ4/ signals for

VME slots 12PL to 19PL

H configure Bus Grant signals for VME slots 12PL to 19PL

Standard Configuration Jumper Positions

Refer to Figure F-4 which is an example of jumper positions and numbers per slot.

H JP1 through JP4 (rack ID jumpers) jumpered to the proper position for

Rack ID, where applicable.

H JP43 remains in its default position

(as shipped from factory). This allows the SYSFAIL signal to be activated by the Series 90-70 CPU.

H JP44 remains in its default position.

This jumpers the LWORD signal in slot 1 to be inactive allowing only

16-bit wide data transfers.

H All other jumpers remain in their factory set default positions.

(2) Series 90-70/VME Configuration

This configuration consists of a Series 90-70

CPU or Bus Receiver module in slot 1PL

and a combination of Series 90-70 modules and 3rd party VME modules in the remaining slots. Series 90-70 modules can

Appendix F VME Integrator Racks F-7

F

F-8

be placed in slots 2PL to 9PL only. 3rd party

VME modules can use the VME slots 12PL to 19PL and slots 2PL to 9PL. Note that all slots have a jumper that allows you to disable the SYSFAIL/ signal to that slot by removing the appropriate jumper.

Note

Integration of 3rd Party VME modules must be in accordance with guidelines described in this manual

(User’s Guide to Integration of 3rd Party

VME Modules, GFK-0448B, or later).

Series 90-70/VME Jumper Positions

H JP 1 through JP4 (rack ID jumpers) jumpered to the proper position for

Rack ID.

H JP43 remains in its default position

(as shipped from factory). This allows the SYSFAIL signal to be activated by the Series 90-70 CPU

(SYSFAIL required by Series 90-70

I/O modules).

H JP44 remains in its default position.

This jumpers the LWORD signal in slot 1 to inactive (for GE Fanuc modules) allowing only 16-bit wide data transfers.

H VME modules can be installed in either the Series 90-70 module slots

(2PL to 9PL) or in the VME slots

(12PL to 19PL).

H If VME modules are installed in the

Series 90-70 module slots (2PL to

9PL) and they use the IRQ1/ - IRQ4/ signals, then you must install the four jumpers in positions that are located to the immediate left of the Series

90-70 slots in use.

H If the VME modules are installed in

VME slots (12PL to 19PL), and the board must pass the Bus Grant and

IACK signals, you must remove five jumpers for each slot being used.

Leave these jumpers in if the board does not need to pass the Bus Grant and IACK

signals on a daisy chain. These jumpers are the top four to the immediate right of the slot being used and the lower (of two jumpers) to the immediate left of the slot being used.

(3) VME Configuration

This configuration consists of a 3rd party

Controller in slot 1PL and 3rd party VME modules in the remaining slots (2PL to 9PL and 12PL to 19PL). Note that each slot has a jumper that allows the SYSFAIL/ signal to be disabled to that slot since all VME modules may not require access to that signal.

VME Jumper Positions

H To configure slot 1 for a 3rd party controller, five jumpers must be removed. There are four jumpers behind the power supply (JP1 to JP4) that must be moved to positions JP39 to JP42. Jumper JP44 must be moved from its default position to the right.

H If VME modules are installed in the

Series 90-70 module slots (2PL to

9PL) and they use the IRQ1/ - IRQ4/ signals, then you must install four jumpers in the positions that are located to the immediate left of the

Series 90-70 slots in use.

H If the VME modules are installed in

VME slots (12PL to 19PL), and the board must pass the Bus Grant and

IACK signals, you must remove five jumpers for each slot being used.

Leave these jumpers in if the board does not need to pass the Bus Grant and IACK

signals on a daisy chain. These jumpers are the top four to the immediate right of the slot being used and the lower (of two jumpers) to the immediate left of the slot being used.


GFK-0448E

Power Supply Extension Cable

For many applications, one power supply is sufficient for the power requirements of two racks. This two-rack operation from a single power supply can be implemented if only 5 volt power of 5.2 amperes or less is required in the second rack.

A 3-foot Power Supply Extension cable available from GE Fanuc (see the Ordering

Information at end of this appendix) provides the necessary interconnection. In addition to +5 volt power, the extension cable includes power sequencing signals necessary for proper system operation.

The Power Supply Extension cable attaches to a 9-pin D-type connector located on the backplane. Access to the connector is through a hole in the left side of the rack as shown in the outline drawing (Figure F-1).

Adequate clearance (approximately 6 inches) must be provided on the left side of the rack for access to the connector.

This connector can also be used to provide power to a user installed 3rd party J2 backplane. An option kit (IC697ACC715) is available for installing a J2 backplane.

Maximum power that can be supplied to the J2 backplane is 5 VDC at 5.2 amps.

The Power Supply Extension cable must be secured before power is applied. It must not be disconnected during system operation.

Slot Addressing

The Series 90-70 PLC system allows user configuration of I/O point references for modules in a rack without the need for board address DIP switches or jumpers. The address structure is described below.

Configuration is done with the configurator function of the Logicmaster t 90-70

Programming Software package. For more information on configuration, see GFK-0263, the Logicmaster 90 Programming Software

User’s Manual.

Note

In order to configure slots 12PL to

19PL, you must have version 4.xx, or later of Logicmaster 90 Programming

Software.

Appendix F VME Integrator Racks

Rack Number

Multiple racks in a system must be assigned a rack number from 0 to 7; the

CPU rack is always Rack 0. The PLC determines the number of each rack in the system from the configuration of four binary-encoded jumpers on the rack’s backplane. These jumpers are located on the backplane directly behind the power supply, which must be removed to gain access to the jumpers.

To set the rack number, move the jumpers corresponding to the 1, 2, 4, and 8 bits to either the 0 or 1 position. The sum of the digits in the 1 position equals the desired rack number. For example, as shown below, rack number 2 would have the 2 bit jumper in the 1 position and the 1, 4 and 8 bit jumpers in the 0 position.

Shield Ground

The bottom rail of the rack is used for module shield grounding. Some Series

90-70 I/O modules have a ground clip that contacts the conductive bottom rail when the module is fully inserted. Shield connections in the user connectors are routed to this ground clip through conductors on the module.

F-9

F

Safety Ground

The ground lug on either side of the rack must be connected to earth ground with not less than an AWG #12 (3.3 mm

2

) wire.

The ground lugs are #8-32.

Warning

If the ground lug is not connected to earth ground, the rack is not grounded. The rack must be grounded to minimize electrical shock hazard which may result in severe personal injury.

Module Retention

Series 90-70 I/O modules have molded latches that automatically snap onto the upper and lower rails of the rack when the module is fully inserted (3rd party VME

modules do not have these latches

).

Optionally, M2.5x8 screws may be used to secure the modules to the rack for high vibration applications.

To remove a Series 90-70 module, first remove the field half of the terminal board

(if it is an I/O module), then grasp the top and bottom of the module to depress the latch releases while pulling the module out.

For more detailed information on removing

I/O terminal boards, refer to the Series 90-70

Programmable Controller Installation Manual or individual data sheets for I/O modules.

Warning

System Noise Immunity

Three easy steps must be taken to properly ground the Series 90-70 PLC system to reduce the possibility of errors due to electrical noise.

1.

Make sure that the power supply mounting screws, especially the bottom two, are properly secured.

2.

The GND terminal on the power supply must be connected to the GND terminal on either side of the rack using AWG

# 12 wire. Use of a ring terminal and star washer is recommended.

3.

The GND terminal on the rack must be connected to a good earth ground.

Do not remove (or insert) modules when either the Series 90-70 PLC power supply or any externally connected power sources are on.

Hazardous voltages may exist.

Personal injury, damage to the module or unpredictable operation of the device or process being controlled may result.

If M2.5x8 screws have been used to secure modules to the rack, remove the screws before removing the modules.

A blank faceplate is available to cover two consecutive unused slots in the rack. See the Ordering Information on page F-12.

VAC power source) for installation on the bottom of the rack for additional cooling if forced air cooling is required when a number of high-power VME modules are installed in the rack and heat build-up could be a problem.

The fan assembly consists of three fans wired in parallel. The fans have a low noise level and are assembled using ball bearings for extended life.

The three fans on the fan assembly are wired in parallel. The fan on the left

(looking at front of rack) has a three foot cable to be wired to the AC power source.

The other two fans are connected through a cable/connector assembly to this fan. It is recommended that the fans be wired to the same source of power as the Series

90-70 PLC so that the fans are energized regardless of whether or not the PLC is energized. This will ensure that the fans are running when the PLC is active.

The following illustration shows the position of the fan assembly when it is mounted on a rack. Note that it is mounted on the bottom of the rack with air flow from the bottom towards the top of the rack. For detailed specifications and installation instructions, refer to the data sheet for the

Rack Fan Assembly, GFK-0637D, or later version.

Application Note for Xycom XVME-420 Intelligent

Peripheral Controller Module

Overview

The following application note describes a successful integration of a third party VME module into the

Series 90-70 PLC system. Note that the Xycom XVME-420 is NOT a fully qualified third party module and has not gone through the Vendor Qualification Program. The application was not intended to represent a real situation, and was constructed only to demonstrate that the Xycom XVME-420 module could be successfully integrated, and made to work as described in its own manual.

The Xycom XVME-420 Intelligent Peripheral Controller module is ideally suited for cost sensitive applications which need more than 1 or 2 serial interfaces for devices such as terminals, bar code readers, and weigh scales. There are four RS-232 (or four TTL compatible) ports per module, as well as an IEEE-P959 expansion port. Internal buffering is available, so it is not necessary for the module to interrupt the CPU, or for the CPU to handle each serial character as it arrives at the port.

Although the module has many different programmable characteristics, the application described in this document is basic and uses two of the four ports. In this application, the module is NOT used as an interrupter, and is used only as a slave, not as a master on the VME bus. Once this application has been successfully duplicated, more complex applications can be attempted.

The XVME manual used for this demonstration was Xycom part number 74420 and was dated 1984.

IMPORTANT NOTE

The standard XVME-420 module needs to be modified slightly to work with the Series

90-70 PLC. The standard module will not correctly recover from the SYSFAIL signal, which is asserted by the PLC during I/O configuration at power up. Xycom is aware of the modification which is required. When ordering this module, be sure to mention the modification.

Application Description

A serial RS-232 Bar Code Reader was connected to port 1 to input data to the PLC. The PLC stores the bar code in registers, verifies it for the correct number of characters and then causes the bar code to be transmitted through port 2 of the module with a BAD BAR CODE error message if appropriate. A Dumb

Terminal was connected to port 2 of the module to receive the echoed bar code and any error message due to mis-verification.

System Configuration

The system configuration for this demonstration consists of the standard Series 90-70 Demo Case with a

100 watt power supply (the module does require +/– 12 VDC). All modules were left in the Series 90-70

Demo rack (with the exception of the power supply being changed to a 100 watt) and the XVME-420 was put in slot 9 which was previously empty. If a bar code reader is not available, it could be exchanged for a dumb terminal or a PC running terminal emulation software on which a bar code could be manually entered (typed). The XVME-420 defaults to look for a carriage return as the record terminator character, although it can be changed. The Universal Simulator Case display unit was used as the dumb terminal for Port 2. The XVME-420 ports default to 9600 baud, 8 bits/character, no parity, 1 stop bit, full duplex.

The only thing that needs to be reconfigured at the universal simulator display unit is the baud rate from

19.2K to 9600 baud. For the demonstration, cables to and from the XVME-420 ports require only transmit, receive and ground to be wired.

The module must be assigned a starting address in the VME address space. You must use address modifier 2DH, and the address must be in the short address space. Although the manual states that AM code 29H can also be used, this will result in attempts by the module to access external global memory instead of its own on-board memory. The module uses 1K byte in the short address space, and the start address can be assigned to any one of 16 specific 1K byte boundaries ranging from 0000H to 3C00H. Note that the short address space that would be used by a Series 90-70 I/O module, for slot 9 of the Series 90-70

CPU rack starts at 4800H, which is outside of the range the XVME-420 can respond to.

To accommodate the XVME-420 in slot 9 for this demonstration, address 2800H was used, which is the start of the address space that would be used by a Series 90-70 I/O module, for slot 5. This is possible because the address modifier code used to get to the VME-420 is 2DH and NOT 29H. The discrete I/O module in slot 5 of the demo cases does not respond to AM code 2DH so there is no conflict between the two modules. Base address 2800H was set with J4 and J7 IN, and with J5 and J8 OUT. In general, any previously unused short VME address space can be used by a 3rd party module.

The bus request jumpers were set to J1=A, J2=B, J6=A. These should not have any effect since the board will not be used as a master.

Jumpers J10-J13 were all set to the A position, and J15-J16 were set to the B position. This is NOT as described in the manual, but it was the way the product was shipped to us, and Xycom confirmed that it was correct. The explanation for the difference is that these jumpers may be set differently depending on the types of memory devices used on the module.

The application was done with J3 IN, but this may work better with J3 OUT. J3=OUT restricts the module to responding to address modifier 2DH instead of 2DH and 29H.

Programming

All of the serial operating parameters such as baud rate, parity, stop bits, and others are programmable on a port by port basis. As noted above, the power-up default parameters were used for this demonstration

(the entire power up default list is on page 4-25 of the Xycom manual).

There are 2 basic modes of operation - character read/write, and record read/write. Character read/write basically turns the board into a four port USART, and requires that the Series 90-70 CPU handle each character individually. This would have severely limited the baud rate which could be handled without missing characters coming into the port, and would have required the construction of a PLC based buffer handler for the data.

The record read/write mode was used, since this takes advantage of the internal buffers on the module.

This application closely followed the example in the Xycom manual on page 3-12 to 3-14 (reading a record under polled operation).

With reference to this example, the host base address is 0, the base address of the I/O interface block is

2800H, the command block is at 2A00H, the data buffer is at 2A14H, and the command is set to read a maximum of 48 bytes.

As noted above, with the default board parameters, the end of record for incoming data is defined as a carriage return. If more than 48 characters arrive before a carriage return arrives, then only the first 48

3

4



characters will be available in the buffer. There are several other ways to configure the XVME-420 to terminate a record including ending the record if a specific number of characters has arrived.

The following describes what is necessary to receive a record on port 1 of the XVME-420. Since the default port and module parameters were used, the remaining tasks for the Series 90-70 CPU are to:

1.

Write the command block described below to address 2A00H. There is nothing magic about address

2A00H except that it is in the module’s dual ported address space, and it is not used for anything else.

The command block basically tells the module/port what to do. But it doesn’t do it until it gets a go command (see item 3). For the Series 90-70, you MUST use an AM code of 2DH at address 2A0DH in the command block or the module might (depending on J3 jumper setting) use it’s inherent mastership capability to attempt an access of the external (non-existent) global memory and cause erroneous operation of the CPU.

2.

Write the command block pointer described below to address 2892H. The command block pointer for each port is at its own fixed location in memory compared to the base of 2800H, and tells the module where to find the command block (item 1 above). Remember you MUST use an AM code of 2DH at address 2893H or the CPU might crash as described above in item 1.

3.

Write 01H to the I/O channel 1 request register at 2882H. This tells the module to look at 2892H to find out where it’s command is, then execute the command.

4.

When the command block is written in step 1, addresses 2A06H and 2A02H are set to FF. These are the response word and response flag respectively. When the CARRIAGE RETURN is received on the port, indicating the end of record, the FF is set to a 0 by the module. The CPU must poll 2A06H to see if the record is complete. If so, then go to step 5.

If the command block contains an invalid command, the address 2A02H will contain a non-0 error code.

5.

After the above steps are completed, the data block can be read at address 2A14H by the 90-70 CPU.

The command block which we used for the read record function is:

Writing a record out of port 2 is almost identical to the above description, except you first have to write the data you want to transmit to the module’s dual ported address space (unless it is already there, as it is with the bar code). Change the command to 06H instead of 05H and write the command block pointer for port 2 instead of port 1 (starts at address 2898H instead of 2892H. Also to execute the command, write

01H to the I/O channel 2 request register at 2883H instead of 2882H.

High Speed Inter-Rack Communications Using Reflective Memory

SUMMARY

There has been considerable interest on the part of traditional VME users to apply the Series 90 t-70 in their applications. Many users require a configuration which allows a Series 90-70 system to be tied to a separate VME system via a high speed inter-rack link. In addition, many Series 90-70 users need a very high speed communications link among multidropped Series 90-70 CPUs.

The VMIVME-5550, a product from VME Microsystems International, was investigated as a possible answer to these needs. A cursory investigation revealed that the VMIVME-5550 is essentially compatible with the Series 90-70 at the VME interface level, and would be useful in some applications. Some restrictions were identified, and are noted on the next page.

No attempt was made to simulate any specific real application beyond the testing for basic Series 90-70 compatibility, and the actual transmission of data between the Series 90-70 systems.

OVERVIEW

The VMIVME-5550 is a reflective memory board. Its primary use is to connect multiple VME and/or Series

90-70 racks together in a multidrop parallel communications link. Each rack must have a master, which can read and write memory on the 5550 board. In a Series 90-70 system, the Series 90-70 CPU is the master. In a more general case, the master is typically a CPU based on a Motorola 680X0 chip.

The inter-rack link can be up to 1000 feet long, with up to 16 nodes on the bus. The bus can run at 20

Mbytes per second over short distances between compatible VME systems. In the Series 90-70 the transfer rate is limited to 10 Mbytes per second due to absence of Lword transfers. Long cables also restrict the maximum data rate.

Any data written by a master to one of the cards is transmitted immediately to all other nodes on the bus to the same relative address in the other cards.

The 5550 might be useful in applications which require

D A high speed communication link between Series 90-70 racks.

D A high speed communication link between Series 90-70 racks and standard VME racks.

D Data sharing between separate systems.

D A Geniust tie-in to a traditional VME based computer. This would be done using a standard Series

90-70 and Genius Bus Controller, with a CPU program providing the data transfer between the CPU

Genius I/O tables and the reflective memory board.

The board is a single wide 6U board, which contains both J1 and J2 connectors. The board is available with different amounts of memory. As tested, the modules contained 256K of dual ported memory, and a

512 byte FIFO. This was the least expensive configuration. Per VMIC’s price list of February 1991, these modules would cost $2195 each in small quantities. This configuration appears to be more than adequate for use in most Series 90-70 related systems.

RESTRICTIONS

Application restrictions which were noted are as follows:

D The board needs 7A at 5V to operate. In many instances, the 100W Series 90-70 power supply would be required to support a configuration which includes this board. A detailed power analysis should be done before deciding on the 55W supply.

D A P2 backplane would be strongly recommended due to the power consumption of the board. The board was run successfully using only a J1 backplane, however this is NOT recommended for a real installation. A P2 kit is available from GE Fanuc as part number IC697ACC715. This kit contains hardware necessary to mount a P2 backplane, which must be purchased from another source. The

P2 backplane would only need to be of sufficient length to support this board, unless additional third party modules in the system also require P2.

D Due to the power consumption noted above, forced air cooling is strongly recommended for an industrial environment. The GE Fanuc Series 90-70 Rack Fan Assembly IC697ACC721 or

IC697ACC724 could be used. In a lab environment, forced air cooling may not be required. If in doubt, temperature measurements should be made, and compared with VMIC’s specifications.

D The ribbon cables which are used as the link transmission media may not be suitable for lengthy cable runs in an industrial environment. VMIC should be consulted if this is a problem.

D Many of the components are on sockets, including a crystal oscillator. It is possible that these components could come loose in a high vibration environment. This board is not recommended for a high vibration environment. Also, be sure to check that all components are seated before plugging in the boards.

D The board includes the ability to interrupt its local CPU when data is received from one of the other racks. This capability must be disabled with the present versions of the Series 90-70. Future versions of the Series 90-70 may allow interrupts of this type to be used. The board is useful even without this function.

This function would still be usable in a standard VME rack with a non Series 90-70 master.

D Discipline is required by each of the masters to ensure that they do not write to the same memory areas as the other masters (at least not at the same time). One approach is to allow all the masters to read the entire memory, but restrict (in local CPU software) write access for each master to a different area of the memory.

D If modification of a common data base by multiple masters is required, a mechanism must be set up in master firmware to ensure that modification of a data byte is not attempted simultaneously by more than one master.

D Extensive compatibility testing, quality testing, and so forth, was not done on this board by GE Fanuc.

Although the board appears to work properly in the application described here, this does not guarantee that it will operate in all environments, or in all applications.


SETUP

The test that was conducted consisted of connecting two Series 90-70 systems together with the 5550 cards, and transmitting data in both directions. In CPU 0, data was read from the reflective memory, incremented, then passed to CPU 1. In CPU 1, the data was read from the reflective memory, then written back to CPU 0.

The two 5550 cards were both mapped at the CPUs VME address 100,000H, and were accessed with AM code 39H. It is not required, however, that all cards on the link have the same base address. The cards could be mapped to different address spaces in each CPU. When the master accesses the board, it is looking for data at an address relative to the base address of the board, not at any absolute address.

For example, if card A is mapped at 100,000H and card B is mapped at 200,000H, then data written to address 100,100H in card A can be read in card B at 200,100H.

The jumpers on both cards were set identically, except for the node ID jumper.

Integration of a 68030 CPU with OS-9

t into the Series 90t-70 PLC

1. Overview

Adding a foreign CPU to a Series 90-70 PLC is an excellent way to provide additional processing power, add an additional operator interface platform, or incorporate a high-level process controller to the system. A real-time operating system such as OS-9 is ideally suited for such an application. OS-9 is a high performance multi-tasking, ROMable operating system for Motorola 680x0 microprocessors. OS-9 provides a complete software development environment including a file system, editors and compilers in a UNIX-like environment.

Several customers have already written applications for OS-9, which are running on non-PLC platforms.

By integrating a 68030 CPU with OS-9 into the Series 90-70 PLC, customers with OS-9 experience and/or canned applications can now take advantage of the industrial I/O provided by the Series 90-70 PLC.

Users who have traditionally used OS-9 (quite often in conjunction with other VME platforms) may find the ability to interface to true industrial I/O in the Series 90-70 PLC particularly appealing.

The application example which follows describes the integration of a 68030 based module, with OS-9 into the Series 90-70 PLC system.

1.1 The Hardware Platform

The Matrix CPU330 is a high performance 68030 based CPU which provides a fast, extended temperature platform for OS-9 applications. Options are available to run at speeds up to 33 Mhz with up to 8 Mbytes of on-board dynamic ram. It provides a variety of real-time controller functions, and includes a Dbus-68 daughterboard interface with many available options.

Matrix is a participant in the GE Fanuc Recommended VME Vendor program, and has developed a custom CPU330 package specifically for use in the Series 90-70 PLC. The part number for this custom version is GE-CPU331-N-2. This part number includes the standard extended temperature CPU330 board with 1 Mbyte of RAM memory, custom OS-9 software, a 25 MHZ clock, and documentation specifically for use in the Series 90-70 PLC.

1.2 The Application

This application note demonstrates the CPU330 being used as both a VME slave and VME master in a

Series 90-70 PLC system. No attempt has been made to use the complete set of hardware functionality of the CPU330 board; rather, an easy to understand application was developed primarily to demonstrate the successful integration of the CPU330 board and OS-9 into a Series 90-70 PLC system and provide a framework for more complex applications.

Integration of a 68030 CPU with OS-9 into the Series 90-70 PLC

To demonstrate the mastership capability of the Matrix CPU board in the Series 90-70 system, a XYCOM

XVME-428 8-port serial card was included in the setup. It not only provides dual port memory for the Matrix

CPU to access, but also demonstrates a realistic application in conjunction with the Matrix CPU330 as a smart bar code reader. The CPU330 is programmable in C, which is provided with the Professional OS-9 package supplied by Matrix. Version 3.2 was used to develop the code shown at the end of this application bulletin.

Also included in the setup is a Matrix DSM module containing a 50 Mbyte hard disk and 3-1/2 inch floppy disk drive. The DSM module contains the OS-9 system software for the disk-based Professional OS-9 and application software. The CPU330 and DSM communicate across the VME backplane. Keep in mind that the DSM is not needed to run the application. In this example, the CPU330 was used as the development environment, as well as the run time platform. The DSM was required only for development of the application program. A program could be developed on a totally different platform, then put into ROM or downloaded for execution on the CPU330.

2. Setup

The setup for this demonstration consists of the following:

Series 90-70 9 slot rack

- 100 Watt power supply (The Matrix CPU330, DSM and XYCOM 428 all require 12V provided by the

100 Watt power supply).

- SLOT 1: Series 90-70 CPU772 with expansion memory daughterboard. The CPU used must have multiple master support. This will be explained further below. The CPU772 is connected to a Workmaster II through a serial cable. The Workmaster II was used to develop the 90-70

CPU ladder program.

- SLOT 2: Matrix GE-CPU331-N-2 with 1 Mbyte DRAM, 25 MHz - 68030, and two

Serial ports. Professional GE-OS9 EPROMs installed. The CPU330 is configured to respond to 400000h - 4FFFFFh in standard address space (AM Codes 39h or 3Dh).

- SLOT 3: Matrix GE-DSM-SF-FFF-050 with 1Mb 3.5I floppy disk drive and 50 Mb hard drive with controller. The DSM is configured to respond to

5000h - 507Fh in short address space (AM Codes 29h or 2Dh).

- SLOT 4: XYCOM XVME-428Intelligent asynchronous serial communication module.

The XVME-428 is, configured as a slave only, responding to 3800h -

3BFFh in short address space (AM Codes 29h and 2Dh).

Note

A separate application note for the XVME-420/428 in a 90-70 environment has been published, if you would like additional information, contact GE Fanuc).

Please refer to GE Fanuc publication GFK-0448 (this manual) for additional information regarding integration of 3rd party VME modules into the Series 90-70 PLC environment.

2.1 Setup Notes

1.

A Standard EIA-232 cable is connected between Serial Port B of CPU330 front panel and a VT100 terminal set for 9600 baud, no parity. This terminal is used as the CPU330 system console.

2.

A serial cable assembly number XVME-930, available from XYCOM is connected between JK1 on the

XVME-428 front panel and a VT100 terminal set for 9600 baud, no parity. Of the four D-connectors from the cable assembly, the one corresponding to serial port 0 is used. This VT100 is used for data entry into the XVME-428 board and can be replaced by any serial device such as a bar code reader

(the OS-9 program, written in C, would need to be modified to accommodate the particular protocol of the bar code reader).

The Matrix DSM uses interrupt request 4 to communicate to the CPU330 board. Special backplane jumpers must be installed in the slots occupied by the CPU330 and the DSM to handle this interrupt.

In this demonstration, the jumpers for IRQ4 at slot 2 (JP5) and slot 3 (JP 9) must be installed.

4.

Since multiple VME master capability is demonstrated in this application note, a multiple-master

Series 90-70 CPU is required. Multiple-master capability has been phased into Series 90-70 CPU models. Please contact GE Fanuc for details on which CPU revisions support multiple VME masters.

5.

The CPU330 , DSM and XVME-428 in this application all require " 12 VDC, therefore the 100 Watt power supply is needed.

6.

A minor mechanical incompatibility problem exists between the Matrix Dbus-68 daughterboards and a standard Series 90-70 PLC rack. None of these daughterboards were used in this application. If you would like to use one of these Dbus-68 daughterboards, you will have to use a GE Fanuc Integrator rack (IC697CHS782/783) instead of the standard 9 slot rack.

7.

GE Fanuc Series 90-70 products require only convection cooling when operating in a 0 - 60 degrees

Celsius environment. Both the CPU330 and XVME-428 will also operate in this environment with convection cooling only. The DSM module however, is only rated at 4 - 45 degrees Celsius and would require fans if operating outside this range. This is not normally a problem since the DSM is typically only used for development (most likely in a controlled environment) and can be removed from many target systems.

2.2 Matrix GE-CPU330 Configuration

The Matrix GE-CPU330 is a standard MD-CPU330 shipped from the factory with jumpers already configured for operation in a Series 90-70 PLC and the special GE-OS9 firmware installed. Please verify that the jumpers are properly installed as described below before applying power to the system. A brief discussion of each jumper setting follows - refer to the MD-CPU330 User’s Manual for more information:

System Controller - Jumpers J7, J11:

EPROM Size - Jumper J4:

Reset/Abort Switch Enable - Jumper J5:

Disable system controller functions by removing J7 and J11. There can be only one slot one controller in the system, and this MUST be the

Series 90-70 CPU.

This jumper is set by the factory to match the EPROMs installed. Do not modify the factory setting.

This jumper should be configured to disable the Reset/Abort switch by removing J5. Using the switch to reset the CPU330 causes SYSFAIL to be activated, thus forcing all Series 90-70 output boards to their default state. Disabling the switch prevents this from happening. The preferred method to reset the CPU330 is to power cycle the entire system.

4


VMEbus Request Level - Jumpers J8, J9, J10:

Serial Port A Flow Control - Jumper J3:

Serial Port A Interface Selection

These jumpers are shipped with Bus Request level 3 set. The Series

90-70 PLC has a fixed priority arbiter with BR1 as the highest priority followed by BR0, BR3 and BR2. Foreign VME masters are only allowed to use BR3 and BR2.

This is configured for RTS/CTS flow control as shipped from the factory. It should be set to match the user ’s Port A serial device.

SPA-330-422 is installed in the DTE configuration as shipped from the factory. It depends on Port A option ordered. Set orientation to select

DCE or DTE according to the user ’s Port A needs.

The standard professional/industrial OS-9 EPROMS were specially modified by Matrix for use in a Series

90-70 PLC. Make sure you specify these EPROMs when ordering OS-9 from Matrix. When you order the

GE-CPU330, the special EPROMs come already installed.

The special GE Fanuc modifications made to the OS-9 EPROMs are as follows:

- The CPU330 VME slave address is at 0400000h. The standard CPU330 slave address was changed to avoid potential conflicts with reserved Series 90-70 PLC addresses.

A special 4K of memory is reserved for data transfers to/from the Series 90-70 PLC. The use of this

memory is completely user defined. This memory starts at offset 0400h from the base address of the board.

VME IRQ4 is the only VME interrupt enabled. Use of IRQ5-7 is not allowed by foreign VME boards.

The professional OS-9 EPROMs will look for the DSM module at address 5000h in short address space. The standard DSM slave address was changed to avoid potential conflicts with Series 90-70

PLC reserved addresses.

2.3 The Matrix DSM Configuration

THE GE-DSM is the standard DSM shipped from the factory with jumpers already configured for operation in a Series 90-70 PLC. Please verify that the jumpers are properly installed as described below before applying power to the system. A brief discussion of each jumper setting follows - refer to the

MD-SCSIFLP User’s Manual for more information:

Base Address - Jumpers J4:

AM Code Response - Jumper J6:

Interrupt Request Level - J3:

VMEbus Request Level - Jumper J5:

Bus Grant Daisy-Chain - Jumpers J7:

SCSI Termination Power - Jumper J1:

High Density Drive - Jumper J2:

Set jumpers for base address of 5000h. The jumpers MUST be set for this address in order for the GE-CPU330 to find the

DSM.

Remove J6 to allow both supervisory and non-privileged access

(Am codes 29h and 2Dh). Will work either way.

Set for Interrupt Request level 4. MUST be set for this level for the GE-CPU330 to recognize the interrupt.

These jumpers are shipped with Bus Request level 3 set. The

Series 90-70 PLC has a fixed priority arbiter with BR1 as the highest priority followed by BR0, BR3 and BR2. Foreign VME masters are only allowed to use BR3 and BR2.

Must be set to correspond with Bus request level which in this case is Bus Grant 3 Daisy-chain.

Remove J1 for no termination power.

Will be set by factory to correspond to DSM model ordered.

2.4 XYCOM XVME-428 Configuration

The XVME-428 Jumper settings were modified slightly from their factory defaults. A brief discussion of each follows - refer to the XVME-428 User’s Manual for more information:

Base address - Jumpers J4, J5, J7, J8:

Address modifier - Jumper J3:

Bus Request level - Jumpers J1, J2, J6:

Memory range select - Jumpers J9-J14:

P2 Power - Jumpers J17, J18, J19:

Set jumpers for base address at 3800h.

Set J4=IN; J5, J7, J8=OUT.

Install J3 for recognition in both supervisory and non-privileged short I/O space (AM Codes 29h and 2Dh).

Use factory default of Bus Request level 3. This is not used since XVME-428 will not be used as a bus master in this application.

These are set by the factory to match the memory installed in the board. Do not modify the factory settings.

Keep all jumpers in B position - no power supplied to P2 connector.

3.Application Programs

3.1 Overview

In this application, the Matrix CPU330 board will collect data from both the XYCOM serial card and the

Series 90-70 CPU, sort it and display the data in a simple bar graph. The data consists of three digit ASCII numbers which will be sorted and displayed by ranges (that is, 100-200, 500-900, and so forth).

The Series 90-70 CPU will periodically write data to the dual port ram on the Matrix CPU and set a flag indicating that data is available. The Matrix CPU330 polls this flag and when it is set, will read the data and reset the flag. This demonstrates use of the CPU330 as a VME slave.

The Matrix board collects data from the XVME-428 board by commanding it to read three characters. The

Matrix CPU then polls the read complete flag. When the read command is complete this flag is set and the Matrix CPU will read the data from the XVME-428 dual port ram. The three digit data is entered at the VT100 keyboard but could come from any serial device such as a bar code reader (the three digit data could represent a three digit bar code for instance). When the three digit data is read by the Matrix CPU, it will echo the data back to the XVME-428 by issuing a write command. The data will then appear on the

VT100 terminal. All commands are written to the XYCOM XVME-428 board by the CPU330. This demonstrates use of the CPU330 as a VME master.

Data collected from the Series 90-70 CPU and XVME-428 is checked, sorted and displayed on the Matrix system console (VT100) in bar graph format. When invalid data is detected, an error flag will be set in the Matrix dual port ram to inform the Series 90-70 CPU of an error (the CPU does nothing with this error).

The C program on the CPU330, and the ladder logic in the Series 90-70 CPU are described later in this document.

3.1.1 Controlling the XVME-428 Serial Card

The XVME-428 power up default settings are used for this application:

8 bits/character, 1 stop bit, no parity

9600 baud

no line control

incoming characters not echoed

record I/O mode (transmit/receive strings of characters)

no request acknowledge interrupt

Commanding the XVME-428 to execute a transmit/receive is a three step process. The first step is to write a command block to the XVME-428 dual port ram. This command block will tell the XVME- 428 what to do and also contains an area for the transmit or receive data (only if 6 bytes or less of data). The second step is to write a pointer to the command block into the Command block pointer for channel 0. This tells the XVME-428 where the command block is located. The third step is to write to the I/O request register for channel 0, initiating command execution.

For simplicity in this application, the Response Flag (byte 6 of the command block) will be polled to determine when the operation has completed. The XVME-428 is also capable of generating an interrupt to the CPU330 upon command completion. Using this method instead would cut down on bus traffic and possibly improve system performance.

The XVME-428 addresses are constructed as follows:

0xfff00000 access to VME short address space from CPU330

+ 0x00003800 base address of XYCOM 428 board

+ 0x00000092 XYCOM 428 pointer register offset

= 0xfff03892 address of XYCOM 428 pointer register

For more information on programming the XVME-428 please refer to the XYCOM XVME-428 Intelligent

Asynchronous Serial Communication Module Users Manual, and the XVME420/428 application note which was previously published.

3.1.2 Series 90-70 CPU and Matrix CPU330 Communications

The Matrix board is used strictly as a slave when communicating to the Series 90-70 CPU. Data is written directly by the Series 90-70 CPU into the Matrix dual port ram. To make this type of communication easy to use, Matrix has reserved a 4K block of dual port memory for transfers between the Series 90-70 PLC and the CPU330. This block of memory does not need to be allocated. It is hidden from OS-9 and therefore will never be used by the operating system or allocated to any application programs. This 4K block of memory is located at offset 0400h from the base address of the CPU330 and is only available on the special GE-OS9 firmware (prom set).

The use of this 4K block of memory is completely up to the user. If you need to use more than 4K bytes of memory for Series 90-70 PLC to Matrix CPU data transfers, have your OS-9 program execute a memory request and store a pointer to this newly allocated memory in the default 4K block. This will allow the PLC to find the extra memory block.
