Driver Design Specification
1. Target Device(s) and Protocol
1.1 Introduction
This section defines the types of I/O Devices that are targeted by this driver.
1.2 Device Manufacturer
OMRON Corporation.
1.3 Device Definition
This driver will communicate with any OMRON programmable logic controller supported within
the OMRON FINS network environment. This includes PLCs using the following interfaces:
?? SYSMAC Link
?? Ethernet
?? Host Link/ Controller Link
1.4 Communications Method
The driver communicates with OMRON PLCs via OMRON supplied “middleware” software
running on the same computer as the driver. This “middleware”
?? isolates the driver from dealing with specific communications methods such as
serial or TCP/IP,
?? allows the driver to communicate with any PLC as long as it’s interface is
supported,
?? provides routing and gateway functions between the driver and PLCs,
?? provides an API for the driver via a DLL.

Notes:
?? All nodes have 4 screw terminal connectors.
?? The shield must be externally earthed at one location only.
?? Data links can be configured for all nodes, including computers.
1.5.2 I/O Device Settings
Controller Link (hereafter referred to as CLK) is a 2-wire, token-passing bus network,
supporting up to 32 nodes per network. Currently, only the CV/CVM1 & C200HX/G/E series of
PLCs support CLK & both units will need hardware & software settings to be made. These are
covered in sections 1.5.2.2 & 1.5.2.3 respectively. CLK networks support computer nodes (to
run Citect) via a 3G8F5-CLK21-E interface board; as discussed in section 1.5.2.1.
The cabling needs to be connected so that all the terminals marked with black squares are
connected together and the same for white square terminals, for all nodes. As the CLK
network uses a bus architecture, the in-built terminator at each of the end nodes will need to
be switched to ON. The terminators for all other nodes need to be switched OFF. These are
shown below. The TER led on the node indicates the status of if the resistance. (Refer to
Omron manual W309-E1-1, section 3.3 or more details on wiring, etc.
All nodes in a CLK network must have a unique station number, between 1-32. Also, the baud
rate of the network is variable & all nodes all will need the same in order to communicate. A
data link can be run between the PLCs simultaneously & transparently to Citect.
When a Controller Link network is operating properly, the Run & Ins LEDs will be lit on every
single node. The SD & RD LEDs will flash or remain ON continuously. Ensure that neither the
ERC & ERH LEDs should be lit. A complete fault finding guide is provided in Omron manual
W309-E1-1, section 9.

Driver Design Specification
1.5.2.1 3G8F5-CLK21-E Computer Board Set Up
The 3G8F5-CLK21-E is an ISA compliant computer board, which does not support “Plug-andPlay”, when used in Windows 95. Node number & baud rate settings are made when
configuring the I/O driver in Citect. There are only two hardware settings that need to be made
on the board before installation:
?? Interrupt Request (IRQ), set to either 10 (the default), 11, 12 or 15, but the
setting must be unique for all other devices configured in your computer.
?? Memory address, is set by a 4-pin dip-switch. One of 16 different memory areas
can be configured, with base address C800(hex) being the default. Ensure that
no other device or program requires the memory allocated by this setting.
Refer to Omron manual W307-E1-1, section 2.1 for more details for on these settings.
1.5.2.2 CVM1-CLK21 PLC Set Ups
A maximum of four CVM1-CLK21 units can be installed per CV/CVM1 system. They can be
mounted anywhere on the CPU or CPU Expansion racks. Only three hardware settings need
to be made:
?? Unit number (00-15), which must be unique for all SIOUs connected to the PLC,
?? Node Number (01-32), must be unique for all nodes on the CLK network
?? Baud rate (2M, 1M or 500K), via pins 1 & 2 of the dip-switch bank. The default
baud rate is 2Mb, allowing up to 500M cable to be run. (Refer to Omron manual
W309-E1-1, section 4.2, for more details for this set up)
If more than one network is used, a network number (001-127) needs to be assigned to the
CLK, in the PLC. Full routing tables will need to be set up if inter-network communications are
required. Both these setting can be made by Syswin; from the Project|Routing Table dialogue.
(Refer to Omron manual Syswin-Eman-3.2, pages 8.25-8.27, for more details).
1.5.2.3 C200HW-CLK21 PLC Set Ups
A maximum of two C200HW-CLK21 units can be installed per C200HX/G/E system. They
must be mounted on the right most slot of the CPU rack. A C200H-COM01/04 board & a
C200HW-CE0** bus must be used to connect the CLK21 unit to the CPU. Only three hardware
settings need to be made:
?? Node Number (01-32), must be unique for all nodes on the CLK network
?? Baud rate (2M, 1M or 500K), via pins 1 & 2 of the dip-switch bank. The default
baud rate is 2Mb, allowing up to 500M cable to be run. (Refer to Omron manual
W309-E1-1, section 4.1, for more details for this set up)
?? Level number (0 or 1), via pin 4of the dip-switch bank which must be different
from the other SIOU connected to the PLC.
If more than one network is used, a network number (001-127) needs to be assigned to the
CLK,in the PLC. Full routing tables will need to be set up if inter-network communications are
required. Both these setting can be made by Syswin; from the Project|Routing Table dialogue.
(Refer to Omron manual Syswin-Eman-3.2, pages 8.25-8.27, for more details).
1.5.3 Software Setup
Refer to section 1.8.3 “Software Setup & Configuration” which is common to all supported
OMRON network types.

?? 10 BASE 2 (ThinNet) fully supported. It uses a bus type architecture.
?? Data Links can not be configured in Ethernet systems.
?? Automatic address resolutions are not supported, as each node has a table to
map IP address to FINS address.
1.6.2 I/O Device Settings
Ethernet (hereafter referred to as ETN) is a standard industrial network supporting at least 126
nodes per network (more nodes can be configured, but these will not be able to communicate
via the FINS protocol). Currently, only the C200HX/G/E & CV/CVM1 series of PLCs support
ETN & both units will need hardware & software settings to be made. These are covered in
sections 1.6.2.3 & 1.6.2.4 respectively.
All communications between PLCs is via the FINS protocol, over UDP/IP. FINs uses a unique
addressing system, which allows inter-network communications, amongst other things. The
FINS address is unrelated to the IP node address used by Ethernet networks. Each node will
therefore require a table to statically map FINS to IP addresses, as will be discussed. ARP,
RAP or any other automatic IP address resolution system can not be used for nodes that need
to communicate with PLCs.
When a Ethernet network is operating properly, the Run LED will be lit continually. After
applying power the Run LED may take up to 20 seconds to turn on. Before this no
communication will be successful. The SD, RD & the Card LEDs will flash occasionally.
Ensure that the ERR LEDs is not lit. A complete fault finding guide is provided in Omron
manual W313-E1-2, section 12.

1.6.2.1 Computer Node Set Ups
Please refer your computer documentation for all details, including set up, relating to its
Ethernet interface board.
1.6.2.2 CS1 PLC Set Ups
Three hardware settings need to be made:
? ? Unit number (00 – 15). The unit number is used to identify individual CPU Bus Units when
more than one CPU Bus Unit is mounted to the same PC.
? ? Node number (1 – 126). With the FINS communications service, when there are multiple
Ethernet Units connected to the Ethernet network, the Ethernet Units are identified by node
numbers. Do not set a number that has already been set for another node on the same
network.
? ? Local IP Address. The nodes on an Ethernet network are identified by IP addresses. Each IP
address is set with 32 bits of binary data. These 32 bits are divided into four 8-bit fields called
octets, and each octet is expressed as four decimal numbers. At the Ethernet Unit, four bits
are expressed as on hexadecimal digit, and the eight hexadecimal rotary switches (the Local
IP Address Switches) on the back of the Unit are used to set the local IP address.
After the hardware settings and connections have been completed, turn ON the power supply to the
PC and create an I/O table. An I/O table is used to identify Units connected to the PC and to allocate
I/O to them. If any change is made to the Unit configuration of a CS1-series PC, an I/O table must be
created to register the Units to the CPU Unit. To create the I/O table, connect a Programming Device
(such as a Programming Console or CX-Programmer) to the PC. Refer to the CX-Programmer User’s
Manual for an explanation of how to create an I/O table using a CX-Programmer.
FINS_Extract.DOC

Driver Design Specification
When the FINS communications service is used, routing tables must be created in advance. The
routing tables describe the transmission path for FINS messages when the FINS communications are
used. Routing tables must be created by a CX-Programmer connected to the PC. For details on how
to connect and use a CX-Programmer, refer to the CX-Programmer User’s Manual.
The settings for the Ethernet Unit’s basic and special functions are made in the CPU Bus Unit
System Setup. For details on how to make the settings, refer to 4-2 CPU Bus Unit System Setup.
1.6.2.3 CV500-ETN01 PLC Set Ups
A maximum of four CV500-ETN01 units can be installed per CV/CVM1 system. They can be
mounted anywhere on the CPU or CPU Expansion racks. CV500-ETN01 supports 10Base5
(ThickNet), 10BASE2 (ThinNet) and 10BASE2 (Twisted-pair), however, an appropriate MAU
(Media Access Unit) needs to be installed on each ETN unit, for each network type.
Only two hardware settings need to be made:
?? Unit number (00-15), which must be unique for all SIOUs connected to the PLC,
?? Node Number (01-7E hex), must be unique for all nodes on the ETN network
(For more details, refer to Omron manual W242-E1-1, section 2.2).
All other settings need to be made in the PLC, through the Syswin. Once the hardware has
been correctly installed, it is generally best to connect Syswin through the serial port on the
CPU (For more details on how to do this, refer to section 1.8.3).
Once online, settings can be made through the Project|Edit I/O Table menu. Once this menu
is displayed, follow these steps:
?? Press the “Create” to write all the I/O units & their locations into the CPU
?? In the I/O table tree diagram, on the left hand side, the SIO Unit branch should
be displayed in bold, indicating the ERTN unit has been detected. Highlight &
expand this branch by clicking in the ‘+’symbol.
?? The ETN unit should be registered along side its unit number. Highlight it &
Click on the “Unit Setup” button. Any registered setting will now be read in from
the ETN unit.
?? The local IP address & Sub-net mask parameters must be filled in, in
accordance of the network requirements.
?? The following settings are generally the most appropriate ones, although for
certain networks, different options may be required:
?? Keep the FINS UDP Port number at its default value of 9600 (this will allow
PLCs to communicate with each other.
?? IP Address settings – Software switch
?? IP Address Conv. Method - Table
?? Click the “IP Ad Table” button to complete FIN to IP address mapping for each
node in the network.
?? When all settings have been made, click on the “Write” button to download
them to the PLC.
(Refer to Omron manual Syswin-Eman-3.2, pages 6.2,3 & 8, for more details).
If more than one network is used, a network number (001-127) needs to be assigned to the
ETN, in the PLC. Full routing tables will need to be set up if inter-network communications are
required. Both these settings can be made by Syswin; from the Project|Routing Table
dialogue. (Refer to Omron manual Syswin-Eman-3.2, pages 8.25-8.27, for more details).

1.6.2.4 C200HW-PCU01 PLC Set Ups
The C200HW-PCU01-E module handles Ethernet for the C200HX/G/E series. This unit is
actually a 386SX computer & provides two PCMCIA slots, for mounting external memory
modules (for high-capacity data storage) or Ethernet interface cards. Only 10BASE2 (ThinNet)
& 10BASET (Twisted-pair) are supported, not 10BASE5 (ThickNet). A maximum of one
PCU01 unit can be installed per C200HX/G/E system and only one of its slots can be used for
an Ethernet PCMCIA module. It is highly recommended that the KNE-PCM/T PCMCIA module
(made by Kingston Technologies) be used for the Ethernet interface. The PSU01 must be
mounted on the right most slot of the CPU rack. A C200H-COM01/04 board & a C200HWCE01* bus must be used to connect the PCU01 unit to the CPU.
Only one hardware setting needs to be made on the PCU01 & it involves the dip-switch bank
on the front of the unit.
?? Level number (0 or 1), via pin 1of the dip-switch bank. Ensure the level is
different from the other Sysmac communication module in the PLC, if one is
installed.
?? Mode, set both pins 5 & 6 to off to communicate via Ethernet. The run led on
the PCU will turn ON about ten seconds after powering the PLC up. (Refer to
Omron manual W313-E1-2, section 4.3, for more details for this set up)
If more than one network is used, a network number (001-127) needs to be assigned to the
PCU, in the PLC. Full routing tables will need to be set up if inter-network communications are
required. Both these setting can be made by Syswin; from the Project|Routing Table dialogue.
(Refer to Omron manual Syswin-Eman-3.2, pages 8.25-8.27, for more details).
1.6.2.4.1 Software Settings
All other settings need to be made in separate software, which is included in the C200HWPCS01-EV1 package. To operate this software, power down the PLC, set pin 5 of the dipswitch bank to ON & turn on the power again. Connect a RS232 cable between COM1 of your
computer & the RS232 port onboard the PCU01. (Refer to the cable mentioned in section
1.7.2.4 for more details). Install the set up software & run it (Refer to Omron manual W313E1-2, sections 7.5 & 7.6). Ensure that no other software is running at the same time.
The following settings need to be made within the setup software:
?? IP Address & Sub-net mask for the PCU01, as determined by the Ethernet
network. These & other settings will be stored in a file called “Setup.fil”.
?? ODI driver, (SPEC3 must be used, not SPEC4). This file is included in the
Kingston PCMCIA card
?? Host list – creates a file called “Hosts.fil”, listing all the nodes in the network
?? IP to FINS address conversion table – saved in a file called “IP_Fins.fil”.
?? Routing table, even if no routing table is used, the local network address must
be set up to say “7 0” (These are actual keys entered in), where 7 would be the
network number in this case. Relay network addresses need only be set is
internode communications are necessary.
?? Gateway address – if no Gateway address is required, enter “0 0 0 0”. (These
are actual keys entered in)
When all these settings have been made, transmit them to the PCU01 unit. This will take
around 30 minutes.

1.6.2.4.2 Checking/modifying the settings in the PCU01
Once all the files have been downloaded to the PCU01, settings can be checked and/or
changed by following the procedure outlined below:
?? Turn the power off the PLC & set both pins 5 & 6 on the PCU01 to ON. Turn the
power back on the PLC. Note that the Run led on the PCU remains off.
?? The PCU01 will now run MS-DOS, version 5.0 and can be monitored via a
standard computer, running Terminal or Hyperterminal. The communications
settings are: 9600 baud, 8 data bits, 1 stop bit & no parity bit. Connect a RS232
cable between the computer & the port on the PCU01 (not the PLC CPU). The
cable required is the same as the one used in serial communications. Refer to
section 1.7.2.4 for more details.
?? Run a program in the PCU01 called setup2. This program accesses the
parameters in the PCU01. Ensure that all parameters are checked, ie: that all
the options are run at least once to view all parameters. (Changes may not be
effectively made if this is not done).

Notes:
?? All C & CV series PLCs support the same protocol & can therefore be networked
together.
?? Interface adaptors can be freely used to convert interfaces between RS232 /
RS422 or optical fibre.
?? Omron Unit B500-AL004-EV1 is the recommended unit for this; it supports all
three interfaces.
1.7.2 I/O Device Settings
All of the Omron C, CV & CVM1 series support serial communications, called Host Link. Host
Link supports up to 32 PLCs (multi-dropped) & is available in either RS232, RS422 or optic
fibre interfaces. As the protocol is exactly the same throughout, All Omron PLCs can be
connected to one network and the various interfaces can be used interchangeably.
Host Link connections are made in one of two ways, either directly to the CPU or via some
extra hardware. Set up for both methods is described below.
1.7.2.1 Hardware Devices
Listed below are all the Host Link hardware modules available & the PLCs they can be used
on. When the Host Link unit is working properly, the run LED should be ON continuously & the
RCV & XMT flash accordingly. The ERR led should always remain OFF.

even parity & 2 stop bits.
?? Baud rate – set all nodes on the network to the same baud rate.
?? Unit number – set all the nodes on the network to a unique number between 00
& 31.
?? Command Levels – enable levels 1, 2 & 3.
?? Procedure – must be set to 1:N.
?? Data format – ASCII

Other settings are generally inconsequential & should be left at defaults.
1.7.2.2 Basic Operation Procedure on CS1-Series PLCs
An overview of the basic operating procedure is provided here.
1. Turn OFF the power supply to the PLC.
2. Set the unit number if a Serial Communications Unit is being used. Set the unit number
switch at the top of the front panel of the Unit to between 0 anf F. the number that is set will
determine which words are allocated as the Setup Area in the DM Area and which words are
allocated in the CIO Area.
3. Install the Board or Unit.
4. Connect the Unit and the external device(s).
5. Turn ON the power supply to the PC.
6. Create the I/O tables if a Serial Communications Units is being used. Creatd the I/O table
using a Programming Device, such as CX-Programmer.
7. Set the serial communications mode and the communications specifications for the Board or
Unit. Use a Programming Device, such as CX-Programmer.
8. make the new settings in the Setup Area valid by performing one of the following.
? ? Turn the power OFF and then ON again. The Setup Area allocated in the DM Area will
be read when the power is turned ON.
? ? Restart the Board by turning ON the Inner Board Restart Bit(A60800) or drestart the Unit
turning ON one of the CS1 CPU Bus Unit Restart Bits (A50100 to A50115, where the bit
number corresponds to the unit number).
? ? Restart the port on the Serial Communications Board by turning ON one of the
Communications Board Port Settings Change Bits (A63601 for port 1 and A63602 for
port 2) or restart the port on the Serial Communications Unit by turning ON one of the
Communications Unit Port Settings Change Bits (A620 to A635: the word will be A620 +
unit number and the bit will be bit 01 for port 1 and bit 02 for port 2).
? ? Execute the STUP(237) instruction. The Board or Unit Setup Area can be changed while
the PC power supply is ON.
Refer to CS1 Serial Communication Board/Module Manual W336-E1-1 for more details.
1.7.2.3 CPU RS232 Ports
Most of the PLCs also have RS232 ports on board that CPUs, which can also be run in other
nodes, to support different protocols or types of communications. The main mode is however
Host Link & this is the only protocol supported by Citect.
Regardless of the software settings, all CPU RS232 ports (except the C**H series) are
controlled by the bank of dip-switches on the front of the CPU. The ports can be set to Host
Link, with “default” parameters, by turning ON pin 5 (for the CQM1 & C200HS/E/G/X series) or
pin 4 (for the CV/CVM1 series). The default settings are: 9600 baud1, 7 data, even parity & 2
stop bits and these can be used to establish communications. (The C**H series requires
DM0920 to be set to 0 to enable the default communication parameters).
When these respect pins are turned OFF, the CPU port will run with its software settings,
which are described below:

Notes:
?? Fibre optic Sysmac Link is not supported.
?? The Sysmac network interface is provided by the C200HW-COM01/04-EV1 for
the C200HX/G/E series.
?? The maximum number of Sysmac Link units installed is reduced if other high
speed communication units are installed.
1.8.2 I/O Device Settings
Sysmac Link (hereafter referred to as SLK) is a token-passing bus network, supporting up to
62 nodes per network. The CV/CVM1, C200HX/G/E C2000H/1000H & C200H/S series of
PLCs support SLK, which need hardware & possibly software settings to be made. These are
covered in sections 1.8.2.2 & 1.8.2.3. SLK networks support computer nodes (to run Citect)
via a 3G8C2-SLK21-E interface board; as discussed in section 1.8.2.1.
Two cabling systems exist: coaxial (75? ) & fibre optic. The bus architecture requires separate
terminators to be installed in the end nodes for the coaxial system. As shown below.
Terminators are not required in optical systems. (Refer to Omron manual W174-E1-4, section
3.3 or more details on wiring, etc. A fault finding guide is provided in section 9 of the same
manual).
All nodes in a SLK network must have a unique station number, between 1-62 & this is set up
on the hardware. A data link can be run between the PLCs simultaneously & transparently to
Citect.
When a Sysmac Link network is operating properly, the Run & Ins LEDs will be lit on every
single node. The SD & RD LEDs will flash or remain ON continuously. Ensure that neither the
TS, ERC & ERH LEDs are lit. A complete fault finding guide is provided in Omron manual
W174-E1-4, section 8.
If more than one network is used, a network number (001-127) needs to be assigned to the
CLK, in the PLC. Full routing tables will need to be set up if inter-network communications are
FINS_Extract.DOC

Driver Design Specification
required. Both these setting can be made by Syswin; from the Project|Routing Table dialogue.
(Refer to Omron manual Syswin-Eman-3.2, pages 8.25-8.27, for more details).
1.8.2.1 3G8C2-CLK21-E Computer Board Set Up
The 3G8F5-CLK21-E is a ISA compliant computer board, which does not support “Plug-andPlay”, when used in Windows 95. Node number settings are made when configuring the I/O
driver in Citect. There are only three hardware settings that need to be made on the board
before installation:
?? Interrupt Request (IRQ), can be set to either 10 (the default), 11, 12 or 15, but
the setting must be unique for all other devices configured in your computer.
?? Memory address, is set by the 8-pin dip-switch. One of 4 different memory
areas can be configured, with base address D800(hex) being the default. Ensure
that no other device or program requires the memory allocated by this setting.
?? Node number (01-62), is set by two rotary dials & must be unique for all nodes
on the SLK network.
Refer to Omron manual W220-E1-1, section 2.3 for more details for these switch settings.
1.8.2.2 CVM1-SLK11/21 PLC Set Ups
A maximum of four CVM1-CLK21 units can be installed per CV/CVM1 system. They can be
mounted anywhere on the CPU or CPU Expansion racks. Only two hardware settings need to
be made:
?? Unit number (00-15), which must be unique for all SIOUs connected to the PLC,
?? Node Number (01-62), must be unique for all nodes on the SLK network
Refer to Omron manual W212-E1-1, section 2.2, for more details for this set up
1.8.2.3 C1000H-SLK11/21 And C200HW-SLK13/14/23/23 PLC Set Ups
A maximum of two of the above units can be installed per appropriate PLC system.
C2000H/1000H-SLK units can be mounted on any slot on the CPU rack that supports
communications. For all the C200H systems, SLK units must be mounted on the right most
slot of the CPU rack. The C200H/S will require a CPU with Sysmac communications & a
C200H-CE0** bus. The C200HX/G/E will require a C200H-COM01/04 board & a C200HWCE0** bus must be used to connect the SLK21 unit to the CPU.
For all SLK units two hardware settings, need to be made:
?? Node Number (01-62), is set buy the must be unique for all nodes on the SLK
network
?? Both units have dip-switches to set the level number (0 or 1), which must be set
to be different to other SIOUs connected to the PLC. It is important that all other
pins indicated as test switches, be left in the OFF position, as requested.
Refer to Omron manual W174-E1-4, section 2, for more details on the mounting positions &
setting up of these units.

1.10 Syswin Programming Software
Syswin is the programming software used to program & configure all the Omron PLCs &
networks. Version 3.2 is the latest version of Syswin & it runs on all networks that support
programming. A simple upgrade is available for all 2.* & 3.* users.
Syswin is a 16-bit Windows application, meaning that it can be installed on Windows 31., 95 &
NT (both NTFS & FAT). It requires around 8Mb RAM & 10Mb of hard disk space & numerous
other requirements in your computer.
Syswin software is copy protected & requires either a hardware dongle or software token to
operate. It is installed by running the Setup program from the first installation disk. For more
information on the installation & copy-protection of Syswin, refer to Omron manual Syswin

Driver Design Specification
V3.2 Users manual, pages 1-6 to 1-9. For more information on advanced installations (ie:
running on networks or remote servers, etc), refer to chapter 11 of the same manual.
The cable configuration used for serial communications, by Syswin is exactly the same as that
used by Citect & is shown in section 1.7.2.4. While Syswin can run simultaneously to Citect, it
does not use the same communication drivers as Citect & can therefore not communicate to
the same device at the same time.
Running Syswin over Ethernet only requires a standard Ethernet card, with all the appropriate
settings made in Windows Control Panel, under networks. (Refer to page 8-10 of the Syswin
Users manual for more details).
Syswin supports the Controller Link board, but only under Windows 3.1 & 95. This is because
the vclkd.386 driver file needs to be loaded in the System.ini file, in the Windows directory.
(This file is supplied in the master disks). Various other settings need to be made in the
System.ini file. (Refer to page 8-10 of the Syswin Users manual for more details) Note that
Citect can not use Controller Link when this file is installed.
Syswin also supports both Sysmac Link & Sysmac Net computer boards, but only when using
Windows 3.1 or 95. This is because two MS-DOS based drivers need to be loaded in the
config.sys file. Both these files are supplied with the software disk supplied with the actual
computer board. (Refer to pages 8-8 & 8-9 of the Syswin Users manual for more details)

?? Select a unique FINS network ID (1-127) for the each ETN module connected to
the CPU BUS. (eg 2)
?? Each ETN module on a CVM1 CPU bus will have a unique unit number (eg 01)
?? The Network routing table of the CPU must be configured before
communications can commence.
?? The steps are as follows:
?? Run SSS
?? press [ESC]
?? press [end], [up arrow] to advance to the Utility menu option Network Support

Make sure that there are no

It appears from experience that the 2 most significant Sub-Code bits may contain error status
indications. At one stage the C200HE CPU had its ERR LED flashing (non-fatal error) and this
resulted in 00/40 Response Codes. The driver currently ignores these bits.

commands. Increase the number
of transmit retry attempts.
Increase the value for the
response monitor time in the
control data.
Read out the error log and correct
as required.
Take corrective action, referring
to troubleshooting procedures in
this section
Check CPU indicators at the
remote node and clear the error in
the CPU (refer to the PC’s
operation manuals)
Check network communications
status and reset the controller
board. If the error still exists,
replace the controller board.
Make sure the unit number is
specified within range and that
the same unit number is not used
twice in the same network.
Check the command code and be
sure the command is supported
by the Unit to which you are
sending it
Check the unit model and
version.
Set the remote node in the
routing tables
Set routing tables at the local
node, remote node, and any relay
nodes.
Set the routing tables correctly,
FINS services eg. CPU_UNIT
may not be running
