Chapter 1 gives an overview of the XP8300 relay board and its specific features.

XP8300 Overview s 13

Z-Worlds XP8300 expansion boards provide a simple way to add relays to a control system built around a Z-World controller. These relay output boards can be connected on the PLCBus in conjunction with other expansion boards. The actuation voltage for the boards relays comes from the controller via the PLCBus port. The XP8300s six relays are high-power relays.

Figure 1-1 illustrates a system of expansion boards mounted on a DIN rail and connected to a controller. Chapter 2, Getting Started, provides instructions and illustrations for connecting a relay board to a controllers

PLCBus port. Appendix D, Simulated PLCBus Connection, provides instructions and illustrations for connecting relay boards to a specific controller that does not have a PLCBus port.

14 s Overview

Figure 1-1. Expansion Board System

XP8300

Features

The XP8300 board has six 24 V high-power relays installed as standard equipment: two are configured as SPDT and four are configured as SPST.

All the relays have wire terminals that allow easy connections to external devices. Each relay is protected with a 10 A fuse. To help eliminate noise transients, a metal oxide varistor (MOV) is attached between pin 1 and pin

3 of each relay.

The inputs (pin 1) and normally open output contacts (pin 3) for all relays on an XP8300 board are accessible on headers H1 and H2. The normally closed outputs (pin 4) for relays 4 and 5 are available at header H4.

The XP8300 also has six LEDs that correspond to the six relays. An LED turns on when the corresponding relays coil is energized. However, an illuminated LED does not verify that the contacts within the relay actually switch.

The XP8310 is a 12 V version of the XP8300.

Connecting Expansion Boards to a Z-World

Controller

Use the 26-conductor ribbon cable supplied with the expansion board to connect the expansion board to the PLCBus on a Z-World controller. See

Figure 2-1. The expansion boards two 26-pin PLCBus connectors, P1 and

P2, are used with the ribbon cable. Z-World recommends using the cable supplied to avoid any connection problems.

XP8300 Controller With PLCBus

Figure 2-1. Connecting XP8300 Expansion Board to Controller PLCBus

Be sure power to the controller is disconnected before adding any expansion board to the PLCBus.

Follow these steps to connect an expansion board to a Z-World controller.

1. Attach the 26-pin ribbon cable to the expansion boards P2 PLCBus header.

2. Connect the other end of the ribbon cable to the PLCBus port of the controller.

Be sure pin 1 of the connector cable matches up with pin 1 of both the controller and the expansion board(s).

3. If additional expansion boards are to be added, connect header P2 on the new board to header P1 of the board that is already connected. Lay the expansion boards side by side with headers P1 and P2 on adjacent boards close together, and make sure that all expansion boards are facing right side up.

$ See Appendix C, Connecting and Mounting Multiple Boards, for more information on connecting multiple expansion boards.

Controllers with simulated PLCBus ports require special expander cables, but are as easily connected. Appendix D, Simulated PLCBus Connection, gives detailed illustrated instructions for connecting relay boards to controllers without PLCBus ports.

18 s Getting Started XP8300

XP8300 Configuration

The XP8300 board holds six high-power relays. Each XP8300 relay has the following specifications:

Standard coil voltage 24 V DC.

3 2

Configuration: SPDT

Contact ratings:

10 A at 24 V DC

10 A at 120 V AC

7 A at 250 V AC resistive maximum.

4 5

Coil Actuation

Voltage: 24 V DC

Figure 2-2. Relay Circuit

Pin 1 is the common. Pin 5 goes to a high-voltage/high-current driver on the relay board. Pin 2 is for the actuation voltage. Turning on the driver allows current to flow through the coil, switching on the relay. Pin 3 is the normally open contact. Pin 4 is the normally closed contact.

Each relay is protected by a 10 A fuse on pin 1. To help eliminate transients, a metal oxide varistor (MOV) is attached between pin 1 and pin 3 on each relay. An LED is connected in line with the coil on each relay, and lights up when current passes through the coil.

Althought the relays are rated at up to 10 A, and are protected with 10 A fuses, the size of the traces on the printed circuit boards limits the current through each relay to 6 A.

Headers H1, H2, and H4 are used to connect external devices to the relays.

Pin 1 and pin 3 connections for all relays are provided on headers H1 and

H2. In addition, header H4 provides pin 4 connections for relays 4 and 5, allowing relays 4 and 5 to be used as SPDT relays. Relays 0 to 3 do not have their pin 4 available for external connection, and therefore can be used only as SPST relays.

Figure 2-3 illustrates the pinouts for the relay connection pins on headers

H1, H2, and H4.

Jumper settings on header J2 determine the actuation voltage for the boards relays. When pins 12 are connected, the actuation voltage is supplied by the +24 V line on the PLCBus. When pins 23 are connected, the actuation voltage is supplied by the VCC line on the PLCBus.

When no pins on header J2 are connected, an actuation voltage must be supplied by connecting a 24 V power supply at sockets V+ and GND on header H3.

!

The XP8300 relays require an actuation voltage of 24 V, and the XP8310 relays require an actuation voltage of 12 V. These relays will not work with J2 pins 23 connected.

Apply a voltage on header H3 only when header J2 is not jumpered. Applying power to the board when J2 pins 12 or

23 are connected can damage the relay board and other boards on the bus.

Setting Board Addresses

Jumpers on header J1 (along with PAL encoding) determine the boards bus address. Figure 2-4 shows the jumper settings to set addresses 07.

Relay Board Addresses

Physical Addresses

Up to 64 addresses are possible on a single PLCBus. The 12-bit address of a particular relay board is determined by two factors: (1) the encoding of the PAL chip installed on the board, and (2) jumper settings on header

J1. Since eight different PALs are available and J1 can be set eight different ways, 64 unique addresses are possible.

A 12-bit address can be conveniently placed on the bus using 4-bit addressing. A 12-bit physical address has the following format:

000z 000y pqrx

Jumper bits are defined by the following pin settings: z = 1 when J1 pins 56 are not connected y = 1 when J1 pins 34 are not connected x = 1 when J1 pins 12 are not connected and pqr is determined by the PAL.

The physical addresses correspond to the following PLCBus addresses.

000zBUSADR0

000yBUSADR1 pqrxBUSADR2

Logical Addresses

PLCBus expansion boards have logical addresses. Relay-specific software defines 64 integer board addresses, 063. The formula mapping physical address to logical address is defined by the following equation: logical address = pqr × 8 + zyx

The PAL encoding (pqr) and jumper bits (z, y, x) are defined above.

For example, a relay board that has PAL FPO4550 (pqr = 101) and J1 pins

5 and 6 connected (zyx = 011) would have the following addresses.

physical address: 000z 000y pqrx = 0000 0001 1011 = 0x01B.

logical address: 101

× 8 + 011

How to Use the Relay Boards

1. Send a reset command to all boards on the PLCBus.

2. Place the address of the target board on the PLCBus.

3. Operate the relays.

Reset Boards on PLCBus

These Dynamic C functions are used to initialize the PLCBus. Use these functions in a program before introducing any code to operate the relays.

 VdInit()

Initializes the timer mechanism.

LIBRARY: VDRIVER.LIB

 void eioResetPlcBus()

Resets all expansion boards connected to the PLCBus.

When using this function, initialize timers with VdInit() before resetting the PLCBus. All PLCBus devices must reset before performing any subsequent operations.

LIBRARY: EZIOPLC.LIB

 void eioPlcRstWait()

Provides a delay long enough for the PLCBus to reset.

This function provides a delay of 12 seconds to ensure devices on the

PLCBus reset. Call this function after resetting the PLCBus.

LIBRARY: EZIOPBDV.LIB

 long int eioErrorCode

Represents a global bit-mapped variable whose flags reflect error occurrences.

This register for this variable is initially set to 0. If the application tries to access an invalid channel, the flag EIO_NODEV (the first bit flag) is set in this register. Note that the other bits in EIO_NODEV deal with networked controllers.


Address Target Board

 unsigned _eioPlcRelayAddr( unsigned BrdAddr );

Converts bit pattern 00000000 00pq rabc to pqrc 000b 000a where pqr is the PAL number and abc is the address of the selected board.

PARAMETERS: The low byte of BrdAddr should contain the logical address (8*PAL# + Board#). The board number is 063 (07 if only the factory default PAL is used).

RETURN VALUE: The bit-mingled BUSADR address pqrc 000b

000a for the XP8300 board.


Operate Relays

 int plcXP83Out( unsigned address, int state );

Energizes a relay on an XP8300 expansion board.

PARAMETERS: address is 8*Board# + Relay#. The board number is 063 (07 if only the factory default PAL is used). The relay number range is 05.

state indicates whether the relay should be energizedthe specified relay is energized when state is non-zero, but is not energized when state is zero.

RETURN VALUE: 0 if the specified XP8300 and relay exist, otherwise 1. If the specified relay/board do not exist, the global variable eioErrorCode is bit-ored with the constant EIO_NODEV .


The plcXP83Out driver implements other function calls such as eioPlcAdr12 eioWriteWR .

, eioPlcAdr4 , eioReadD0 , eioReadD1 , and

Be sure power to the controller is disconnected before adding any expansion board to the PLCBus.

Follow these steps to connect an expansion board to a Z-World controller.

1. Attach the 26-pin ribbon cable to the expansion boards P2 PLCBus header.

2. Connect the other end of the ribbon cable to the PLCBus port of the controller.

Be sure pin 1 of the connector cable matches up with pin 1 of both the controller and the expansion board(s).

3. If additional expansion boards are to be added, connect header P2 on the new board to header P1 of the board that is already connected. Lay the expansion boards side by side with headers P1 and P2 on adjacent boards close together, and make sure that all expansion boards are facing right side up.

$ See Appendix C, Connecting and Mounting Multiple Boards, for more information on connecting multiple expansion boards.


Controllers with simulated PLCBus ports require special expander cables, but are as easily connected. Appendix D, Simulated PLCBus Connection, gives detailed illustrated instructions for connecting relay boards to controllers without PLCBus ports.

Jumper settings on header J2 determine the actuation voltage for the boards relays. When pins 12 are connected, the actuation voltage is supplied by the +24 V line on the PLCBus. When pins 23 are connected, the actuation voltage is supplied by the VCC line on the PLCBus.


When no pins on header J2 are connected, an actuation voltage must be supplied by connecting a 24 V power supply at sockets V+ and GND on header H3.

!

The XP8400 relays require an actuation voltage of 24 V.

These relays will not work with J2 pins 23 connected.

Apply a voltage on header H3 only when header J2 is not jumpered. Applying power to the board when J2 pins 12 or

The physical addresses correspond to the following PLCBus addresses.

000zBUSADR0

000yBUSADR1 pqrxBUSADR2

Logical Addresses

PLCBus expansion boards have logical addresses. Relay-specific software defines 64 integer board addresses, 063. The formula mapping physical address to logical address is defined by the following equation: logical address = pqr × 8 + zyx

The PAL encoding (pqr) and jumper bits (z, y, x) are defined above.

For example, a relay board that has PAL FPO4550 (pqr = 101) and J1 pins

5 and 6 connected (zyx = 011) would have the following addresses.

physical address: 000z 000y pqrx = 0000 0001 1011 = 0x01B.

logical address: 101

B

× 8 + 011

= 43 = 0x2B.

Certain library functions expect a logical relay address.

How to Use the Relay Boards

1. Send a reset command to all boards on the PLCBus.

2. Place the address of the target board on the PLCBus.

3. Operate the relays.

Reset Boards on PLCBus

These Dynamic C functions are used to initialize the PLCBus. Use these functions in a program before introducing any code to operate the relays.

 VdInit()

Initializes the timer mechanism.

LIBRARY: VDRIVER.LIB


Resets all expansion boards connected to the PLCBus.

When using this function, initialize timers with VdInit() before resetting the PLCBus. All PLCBus devices must reset before performing any subsequent operations.


 void eioPlcRstWait()

Provides a delay long enough for the PLCBus to reset.

This function provides a delay of 12 seconds to ensure devices on the

PLCBus reset. Call this function after resetting the PLCBus.


 long int eioErrorCode

Represents a global bit-mapped variable whose flags reflect error occurrences.

This register for this variable is initially set to 0. If the application tries to access an invalid channel, the flag EIO_NODEV (the first bit flag) is set in this register. Note that the other bits in EIO_NODEV deal with networked controllers.


Address Target Board

 unsigned _eioPlcRelayAddr( unsigned BrdAddr );

Converts bit pattern 00000000 00pq rabc to pqrc 000b 000a where pqr is the PAL number and abc is the address of the selected board.

PARAMETERS: The low byte of BrdAddr should contain the logical address (8*PAL# + Board#). The board number is 063 (07 if only the factory default PAL is used).

RETURN VALUE: The bit-mingled BUSADR address pqrc 000b

000a for the XP8400 board.


Operate Relays

 int plcXP84Out( unsigned address, int state );

Energizes a relay on an XP8400 expansion board.

PARAMETERS: address is 8*Board# + Relay#. The board number is 063 (07 if only the factory default PAL is used). The relay number range is 07.

state indicates whether the relay should be energizedthe specified relay is energized when state is non-zero, but is not energized when state is zero.

RETURN VALUE: 0 if the specified XP8400 and relay exist, otherwise 1. If the specified relay/board do not exist, the global variable eioErrorCode is bit-ored with the constant EIO_NODEV .


The plcXP84Out driver implements other function calls such as eioPlcAdr12 eioWriteWR .

Chapter 7 gives an overview of the SE1100 relay board and its specific features.

SE1100 Overview s 45

Z-Worlds SE1100 expansion boards provide a simple way to add relays to a control system built around a Z-World controller. These relay output boards can be connected to the digital outputs of any Z-World controller.

The SE1100 adds expansion capability even to boards without a Z-World

PLCBus interface. The SE1100s four SPDT relays are high-power relays.

Figure 7-1 illustrates a system of expansion boards mounted on a DIN rail and connected to a controller. Chapter 8, Getting Started, provides instructions and illustrations for connecting the SE1100 relay board to a controllers digital outputs.


46 s Overview SE1100

Features

The SE1100 relay board is designed to interface to the digital outputs of any Z-World controller. The boards four relays have a 6.3 A fuse connected to the common pin for overcurrent protection. In addition to the fuses, a snubber circuit across the common and the normally open/ normally closed pins suppresses voltage spikes across the contacts. All of the signals from the four SPDT relays are brought out to header J1.

The interface voltage has a range of 5 V to 24 V. A 24 V DC supply is needed to power the relays. When driving the relays with high-voltage drivers, an SE1100 can be located up to 15 m (50 feet) from the controller.

The opto isolation between the controller and the relays provides an extra level of assurance to guard against noise from high-voltage transients.

The LEDs on the relay board indicate the status of the relays. When an

LED is on, the relay associated with that LED is energized. When an LED is off, the relay is in a default state. The default state is for the common terminal to be connected to the normally closed terminal.

The onboard linear regulator provides the regulated +5 V to all the logic elements. The relays and the LEDs are driven with the unregulated DC input voltage. Altogether, the SE1100 draws approximately 80 mA from the DC power supply input when all the relays are turned on.

SE1100 Configuration

The SE1100 board holds four high-power relays. Each SE1100 relay has the following specifications:

Standard coil voltage 24 V DC.

Configuration: SPDT

Contact ratings:

10 A at 24 V DC or 120 V AC,

7 A at 250 V AC resistive maximum.

4 5

Coil Actuation

Voltage: 24 V DC


Pin 1 is the common. Pin 5 goes to a high-voltage/high-current driver on the relay board. Pin 2 is for the actuation voltage. Turning on the driver allows current to flow through the coil, switching on the relay. Pin 3 is the normally open contact. Pin 4 is the normally closed contact.

Each relay is protected by a 6.3 A fuse on pin 1. To help eliminate transients, a resistor/capacitor pair is attached between pin 1 and pin 3 on each relay. An LED is connected in line with the coil on each relay, and lights up when current passes through the coil.

Althought the relays are rated at 10 A, they are protected with

6.3 A fuses because the size of the traces on the printed circuit boards limits the current through each relay to 6 A.

Header J1 is used to connect external devices to the relays.

Figure 8-5 illustrates the pinouts for the relay connection pins on header J1.

PLCBus Overview

The PLCBus is a general-purpose expansion bus for Z-World controllers.

The PLCBus is available on the BL1200, BL1600, BL1700, PK2100,

PK2200, and PK2600 controllers. The BL1000, BL1100, BL1300,

BL1400, and BL1500 controllers support the XP8300, XP8400, XP8600, and XP8900 expansion boards using the controllers parallel input/output port. The BL1400 and BL1500 also support the XP8200 and XP8500.

The ZB4100s PLCBus supports most expansion boards, except for the

XP8700 and the XP8800.

The SE1100 adds expansion capability to boards with or without a

PLCBus interface. Table A-1 lists Z-Worlds expansion devices that are supported on the PLCBus.

Two independent buses exist on a 26-conductor connector: the LCD bus and the PLCBus.

LCD Bus Signals

The LCD bus consists of the following signals:

LCDX positive-going strobe.

/RDX negative-going strobe for read.

/WRX negative-going strobe for write.

A0X address line for LCD register selection.

D0X-D7X bidirectional data lines (shared with expansion bus).

The LCD bus is used to connect Z-Worlds OP6000 series interfaces or to directly drive certain small liquid crystal displays. Figure A-2 illustrates the connection of an OP6000 interface to a BL2100 controller.

PLCBus Signals

The PLCBus may be used as a 4-bit bus (D0XD3X) or as an 8-bit bus

(D0XD7X). Whether it is used as a 4-bit bus or an 8-bit bus depends on the encoding of the address placed on the bus. Some PLCBus expansion cards require 4-bit addressing and others (such as the XP8700) require

8-bit addressing. These devices may be mixed on a single bus.

The PLCBus consists of the following signals.

/STBX negative-going strobe.

A1XA3X three control lines for selecting bus operation.

D0XD3X four bidirectional data lines used for 4-bit operations.

D4XD7X four additional data lines for 8-bit operations.

/AT attention line (open drain) that may be pulled low by any

device, causing an interrupt.

XP8300/XP8400/SE1100 PLCBus s 59

Registers and Addresses

There are eight registers corresponding to the modes determined by bus lines A1X, A2X, and A3X. Writing or reading one of these registers takes care of all the bus details. Functions are available in Dynamic C libraries to read from or write to expansion bus devices.

To communicate with a device on the expansion bus, first select a register associated with the device. Then read from or write to the register. The register is selected by placing its address on the bus. Each device recognizes its own address and latches itself internally. The registers are listed in Table A-2.

A typical device has three internal latches corresponding to the three address bytes. The first is latched when a matching BUSADR0 is detected. The second is latched when the first is latched and a matching

BUSADR1 is detected. The third is latched if the first two are latched and a matching BUSADR2 is detected. If 4-bit addressing is used, then there are three 4-bit address nibbles, giving 12-bit addresses. In addition, a special register address is reserved for address expansion. This address, if used, would provide an additional four bits of addressing when using the

4-bit convention.

If eight data lines are used, then the addressing possibilities of the bus become much greater: more than 256 million addresses according to the conventions established for the bus.

Place an address on the bus by writing (bytes) to BUSADR0, BUSADR1, and BUSADR2 in succession. Since 4-bit and 8-bit addressing modes must coexist, the lower four bits of the first address byte (written to

BUSADR0) identify addressing categories, and distinguish 4-bit and 8-bit modes from each other.

There are 16 address categories, as listed in Table A-3. An x indicates that the address bit may be a 1 or a 0.

This scheme uses less than the full addressing space. The mode notation indicates how many bus address cycles must take place and how many bits are placed on the bus during each cycle. For example, the 5 × 3 mode means three bus cycles with five address bits each time to yield 15-bit addresses, not 24-bit addresses, since the bus uses only the lower five bits of the three address bytes.

XP8300/XP8400/SE1100 PLCBus s 61

Z-World provides software drivers that access the PLCBus. To allow access to bus devices in a multiprocessing environment, the expansion register and the address registers are shadowed with memory locations known as shadow registers. The 4-byte shadow registers, which are saved at predefined memory addresses, are as follows.

SHBUS0

Bus expansion

SHBUS0+1

BUSADR0

SHBUS1

SHBUS0+2

BUSADR1

SHBUS1+1

SHBUS0+3

BUSADR2

Before a new addresses or an expansion register value is output to the bus, its value is stored in the shadow registers. All interrupts that use the bus save the four shadow registers on the stack. Then, when exiting the interrupt routine, it restores the shadow registers and outputs the three address registers and the expansion registers to the bus. This allows an interrupt routine to access the bus without disturbing the activity of a background routine that also accesses the bus.

To work reliably, bus devices must be designed according to the following two rules.

1. The device must not rely on critical timing such as a minimum delay between two successive register accesses.

2. The device must be capable of being selected and deselected without adversely affecting the internal operation of the controller.

62 s PLCBus XP8300/XP8400/SE1100

Device Allocation

4-Bit Devices

Digital output devices, such as relay drivers, should be addressed with three 4-bit addresses followed by a 4-bit data write to the control register.

The control registers are configured as follows: bit 3 bit 2 bit 1 bit 0

A2 A1 A0 D

The three address lines determine which output bit is written. The output is set as either 1 or 0, according to D. If the device exists on the bus, reading the register drives bit 0 low. Otherwise bit 0 is a 1.

For digital input, each register (BUSRD0) returns four bits. The read register, BUSRD1, drives bit 0 low if the device exists on the bus.

Table A-4 provides the address allocations for the registers of 4-bit devices.

XP8300/XP8400/SE1100 Connecting and Mounting Multiple Boards s 75

Connecting Multiple Boards

Eight or more expansion boards can be connected (daisy chained) at one time. The actual number of expansion boards may be limited by capacitative loading on the PLCBus.

Be sure that each expansion board has a unique address to prevent communication problems between the controller and the expansion board.

Follow these steps to install several expansion boards on a single PLCBus.

1. Place all expansion boards right side up.

2. Use the ribbon cable supplied with the boards.

3. Connect one board to the main controller.

4. Connect another expansion board to the first expansion board, connecting each boards header P1 to the adjacent boards header P2.

Figure C-1 illustrates a controller with expansion boards attached.

Figure C-1. Connecting Multiple Expansion Boards

Do not twist the ribbon cable or mount the expansion boards

upside down! Damage may occur. Be sure Pin 1 of P1 and P2 of each board matches up with Pin 1 of the previous board.

Pin 1 should be at the lower right when the expansion board is right side up, that is, the board markings are right side up.

When several expansion boards are connected, there may be a voltage drop along the network of expansion boards. No action is necessary as long as the digital voltage, VCC, is greater than 4.9 V on the last board.

!

VCC can be measured at pin 2 on header P1, and GND is pin 1 on header P1.

76 s Connecting and Mounting Multiple Boards XP8300/XP8400/SE1100

There are two ways to compensate for the voltage dropoff. The easiest way is to connect +5 V DC and ground from the host controller to pins 2 and 1 of header P1 on the last expansion board. Another solution, which can approximately double the number of boards that could otherwise be connected to a single controller, is a Y cable available from Z-World.

Figure C-2 illustrates the use of the Y cable.

Mounting

The XP8300, XP8400, and SE1100 expansion boards can be installed in modular plastic circuit-board holders attached to a DIN rail, a widely used mounting system, as shown in Figure C-3.

The circuit-board holders are 77 mm wide and come in lengths of

11.25 mm, 22.5 mm , and 45 mm. The holders, available from Z-World and from other suppliers, snap together to form a tray of almost any length.

Z-Worlds expansion boards are 72 mm wide and fit directly in these circuit-board holders.

Z-Worlds expansion boards can also be mounted with plastic standoffs to any flat surface that accepts screws. The mounting holes are 0.125 inches

(1/8 inch) in from the edge of a board, and have a diameter of 0.190 inches.

 int plc_poll_node( int board )

Returns 1 if the board identified by physical address board can be found on the PLCBus and 0 if not.

 void plc_set_relay( int board, int relay, byte state )

Switches a relay on an XP8300 or XP8400 board.

PARAMETERS: relay must be from 07 (05 on an XP8300 board).

state must be 1 (on) or 0 (off).

board must be a logical board address (063).

 void Reset_PBus() void rset_pbus_wait()

The function Reset_PBus resets the PLCBus. The function

Reset_PBus_Wait provides the necessary delay (~450 ms) for the bus to reset.

 int plcrel_addr( int board )

Returns the (nibble-interchanged) bus address for a relay board identified by a logical address (063).


PBUS_TG.LIB

The PBUS_TG.LIB

library allows the BL1000 to operate Z-Worlds relay boards and the XP8600 expansion boards. The PBUS_TG.LIB

library does not support any other expansion boards.

The functions in this library are identical (except for internal details) to those in the PBUS_LG.LIB

library.

PBUS_LG.LIB

The PBUS_LG.LIB

library allows the BL1100 to operate Z-Worlds relay boards and the XP8600 expansion boards. This library does not support any other expansion boards.

There are three groups of functions in this library. The two groups used by relay boards are listed in Table D-3. Analogous functions exist in other libraries. For example, reset_pbus in PLC_EXP.LIB

is used with controllers with a PLCBus and performs the same function as Reset_PBus in this library, which is used with the BL1100 and the BL1300.

Carries out a BUSWR cycle.


 int Poll_PBus_Node( int addr )

Returns 1 if there is a board at addr on the PLCBus, and 0 if not. The first and third nibbles of addr must be interchanged: if the bus address is 0x125, addr must be 0x521.

 int Relay_Board_Addr( int board )

Returns the (nibble-interchanged) bus address for a relay board identified by a logical address (0-63).

 void Reset_Pbus() void Reset_Pbus_Wait()

The function Reset_PBus resets the PLCBus. The function

Reset_PBus_Wait provides the necessary delay (~450 ms) for the bus to reset.

 void Set_PBus_Relay( int board, int relay, int state )

Switches a relay on an XP8300 or XP8400 board. relay must be from 07. state must be 1 (on) or 0 (off). board must be specified by a logical board address (063).

DRIVERS.LIB

The functions set12adr , read12data , and write12data in

DRIVERS.LIB

use 12-bit bus addresses. When using the functions in the drivers library, swap the first and third nibbles of the address before passing the address to the function. For example, if the address is 0x125, pass

0x521.


Sample Projects

The following two sample programs activate the relays on one or more

XP8300 or XP8400 boards attached to a controller. Two versions of the program are shown: one for PLCBus controllers, and one for the BL1100 and BL1300.

The following instructions tell how to set up a system, write and compile a program, and run a sample program to operate relay boards on a bus.

PLCBus Controllers

Instructions

1. Power up the controller and make sure it is working properly. If you encounter problems, consult the controllers reference manual.

2. Disconnect power from the controller.

3. Using a PLCBus ribbon cable, connect header P2 of the relay board to the PLCBus on the controller. Make sure both boards are right-side up, with their input and output headers facing toward you. If you have additional relay boards, chain them to the first board with PLCBus ribbon cables.

4. Check the jumpers on headers J1 and J2 on the relay boards. With only one board, leave J1 unjumpered. With more than one board, leave J1 unjumpered on the first board and set J1 with a different and unique address on each additional board. On every relay board, connect pins

12 on J2. This connection causes each board to draw its relayactuation voltage from the +24 V provided over the PLCBus by the controller.

!

When using the standard XP8300 or XP8400 with 24 V relays, the controller must be powered by a 24 V supply or 24 V must be brought in externally in order to actuate the relays reliably.

5. Power up the controller and bring up Dynamic C on your PC. If you encounter problems reestablishing communications between your PC and the controller, consult the controllers reference manual.

6. Open and run the sample program. Refer to the Dynamic C Technical

Reference manual for detailed instructions on running a program.

7. The LEDs on the relay board(s) will begin flashing to indicate the relays are actuating.


Sample Program

The relay board demonstration program can be used to locate all XP8300 and XP8400 expansion boards. The program then loops, activating the relays on each board. For each board, the program concludes with an allon/all-off sequence. To locate each board, the program polls all 64 possible addresses, then displays the logical address in Dynamic Cs

STDIO window for each board that responds.

Controllers with Simulated PLCBus

Instructions for BL1000 and BL1100

1. Power up the BL1000 or BL1100 and make sure it is working properly.

If you encounter problems, consult the controllers technical reference manual.

2. Disconnect power from the controller.

3. Using the appropriate cable, connect the XP8300 or XP8400 to the

PIO port on the controller. See Appendix D, Simulated PLCBus

Connection, for detailed information regarding this cable. With more than one relay board, chain the additional boards to the first one with

PLCBus ribbon cables. Make sure all relay boards are positioned with headers facing the same direction.

4. Check header J1 on the relay board(s) for correct jumper setting(s).

With only one board, leave J1 unjumpered. With more than one board, leave J1 unjumpered on the first board and set J1 with a different and unique address on each additional board.

5. Make sure that header J2 has no pins connected. Connect a wall transformer or equivalent 24 V direct current power supply to the V+ and GND terminals on header H3 (when using XP8300) or on header

H1 (when using XP8400).

6. Power up the controller and bring up Dynamic C on the host PC. If a problem reestablishing communication occurs, consult Dynamic C

Technical Reference manual.

7. Open and run the program. See the Dynamic C Technical Reference manual for details on opening and running programs.

8. The LEDs on the relay board(s) will begin flashing to indicate that the relays are actuating.


Sample Program for BL1000 and BL1300

The program locates all XP8300 and XP8400 boards attached to the

PLCBus. The program then loops, activating the relays on each board.

For each board, the program concludes with an all-on/all-off sequence. To locate boards, the program polls all 64 possible addresses. The integer

(logical) address of each board that responds is displayed in Dynamic Cs

STDIO window.
