The SYSMAC LINK is an FA network that can send and receive large data packets flexibly and easily among advanced OMRON Programmable Controllers
(CS-series, C200HX/HG/HE-series, C-series, CVM1, and CV-series PCs) and
IBM PC/AT or compatible computers.
The SYSMAC LINK supports data links that continuously share certain ranges
of data and a message service that can be used to send and receive specific
data when required. Data link areas can be freely set to create a flexible data link
system and effectively use data areas.
The network is connected using either coaxial cable or optical fiber cable, and
high-volume data transmissions at high speed allow construction of a wide
range of networks, from low-level systems to highly complex systems.

1-1-2 Features
The SYSMAC LINK FA Network has the following features to meet the various
requirements of FA sites.
Data Links
Flexible and efficient data links can be created to automatically transfer large
amounts of data as listed below.

Specifications
508 words max. (254 words max. in the CIO/LR Area
and 254 words max. in the DM Area)
Coaxial or Optical SYSMAC LINK PCI Support Board:
2,966 words max.
Data links can be configured automatically, or they can be configured by the user
to freely change the sizes of the data areas used. A data link can also receive
only part of the data sent from another node. This function enables nodes to receive only the required data, thereby increasing data link efficiency.
Message Service
The message service can send and receive up to 552 bytes of data (including
the FINS header), allowing large volumes of data to be sent and received without
having to be split up.
Coaxial Cable or Optical Fiber Cable Connection
The SYSMAC LINK Units can be connected to the network using either coaxial
cable or optical fiber cables.
Optical fiber cable (H-PCF cable) has superior noise resistance, so the system
can provide highly reliable communications even in very noisy conditions.
With H-PCF cable, the total communications distance can be up to 20 km (1 km
max. between nodes when using the adhesive polishing method), which allows
long-distance and large-scale networks.
Communications between Different Models of PCs
The following SYSMAC LINK Units are available for communications between
different PCs. Wired Units and Optical Units, however, cannot be used together
in the same SYSMAC LINK Network.

• SYSMAC LINK PCI Support Board for IBM PC/AT or compatibles
Flexible Inter-network Connections
The SYSMAC LINK Network can be connected to another network (Ethernet,
SYSMAC NET Link, SYSMAC LINK, or Controller Link network) through a CSseries or CV-series PC. By installing Ethernet, SYSMAC NET Link*, or SYSMAC
LINK, or SYSMAC LINK Communications Units on the same CS-series PC or
CV-series PC, a message service can be created with nodes in the interconnected networks through that PC. Up to three network levels are possible.
Note *A SYSMAC NET Link Unit cannot be mounted in a CS-series PC.
Improved Error Handling (RAS Functions)
Error Log and Data Link
Status Display
An error log enables quick handling of errors by recording the time the error occurred and error details. The current SYSMAC LINK Unit and Support Board status are also available, as are the data link and network status.
Polling Node Backup
When an error occurs in the polling node that controls the SYSMAC LINK Network, another node automatically becomes the polling node. This prevents an
error at a single node from influencing other nodes on the network, achieving a
highly reliable system.
Node Bypass Function
In an Optical SYSMAC LINK Network, data communications can be continued
by bypassing the node, even when a node in the communications line malfunctions or the PC or computer power supply is turned OFF. This prevents the whole
network system from being affected by a node malfunction or power interruption.
To use the bypass node function, backup power must be supplied to the SYSMAC LINK Units/Support Boards.

1-1-3 What Is a SYSMAC LINK Support Board?
A SYSMAC LINK Support Board is used to directly connect an IBM PC/AT or
compatible with an ISA or PCI slot to a SYSMAC LINK Network. A SYSMAC
LINK Support Board supports data links, a message service, and RAS functions
in the same way as a SYSMAC LINK Unit.

packages of communications middleware. These software packages must be
purchased separately. For details, refer to the manual for the appropriate software.
1-1-5 Outline of PCI Bus SYSMAC LINK Support Board Functions
Data Links
SYSMAC LINK Support Board data link data is stored in the event memory in the
computer. Event memory is shared memory with names such as DM or CIO, and
is stored in the computer memory. Event memory recreates virtually the DM
Area and CIO Area of an OMRON PC.
Event memory can be written or read by executing the C library data link data
read/write functions SlkWriteDatalink( ) and SlkReadDatalink( ) from the user
program.

2-2-2 Wiring the Optical Fiber Cables
All of the nodes in the Optical SYSMAC LINK Network are connected in a line
(daisy-chain configuration) with H-PCF Optical Fiber Cables.
Begin connection with the rightmost connector (SL1) of the highest node in the
network and connect to the leftmost connector (SL2) in the next lower node, as
shown in the following diagram.
The nodes can be connected in any order, but connect the nodes in the order of
node addresses (i.e., node 1, node 2... node 62) as much as possible to reduce
the effect on the communications time if a wire breaks.
Always cover the unused connectors on the highest and lowest nodes in the network with the enclosed Optical Connector Covers.

Note
1. Always use the specified Optical Fiber Cables.
2. The maximum distance between nodes depends on the method used to attach the connector to the cable.
2-2-3 Installing Connectors
A special connector is used to connect the Optical Fiber Cable to the SYSMAC
LINK Support Board.
This manual does not provide details on attaching Connectors to the Optical Fiber Cable.
Connect the nodes in order beginning with the highest node in the network and
continuing on to lower nodes.
• Always turn OFF the computer and backup power supply before connecting
Optical Fiber Cables or the backup power supply connector.
• Special tools are required to attach Optical Fiber Cables to the connectors.
The cable may disconnect from the connector if the proper tools and methods
are not used during cable assembly.
Connection Procedure
1, 2, 3...
1. The Optical Fiber Cable’s power supply line is not used, so it can be cut.
2. As shown in the following diagram, secure the Optical Fiber Cable, and secure the clamp to the mounting bracket. Secure the two cables simultaneously for nodes (except the end nodes). Pay attention to the orientation of
the mounting bracket and the connector position when connecting the cable

3. Install the mounting bracket on the Board with the screws provided. Insert
the tip of the mounting bracket with the grooves into the hole on the Board
surface until it locks firmly (a), and then secure the other end of the mounting
bracket using the screw (b). Take care not to bend or pull the Optical Fiber
Cable forcefully.
(The cable was omitted from the diagram
to make the connector more visible.)
4. Remove the Optical Connector Cover from the Board again. If there are covers on the end connectors of the Optical Fiber Cable, remove them.
5. Double-check the direction of the cables. The cable from the node higher in
the network connects to the Board’s right connector and the cable to the
node lower in the network connects to the Board’s left connector. Insert the
cable’s connectors fully into the Board’s connectors.
Connection Precautions
• Insert the connectors completely and check that the connectors are locked before starting operation.
27

Each node requires a backup power supply for the node bypass function. Several nodes can be connected to a single power supply or each node can be connected to an independent power supply. If several nodes are connected to a
single power supply, be sure to wire each node separately as shown in the diagram.
Note Use a separate power supply as the backup power supply. Do not use the same
power supply being used as the I/O power supply, equipment (such as motors)
power supply, or control power supply.
2-3-1 Backup Power Supply Specifications
The input specifications for the backup power supply to the SYSMAC LINK Unit
and Support Board are described below. When providing a backup power supply, make sure that the following specifications are satisfied.

An OMRON S82K-series Power Supply Unit is recommended.
Note
1. If connecting multiple nodes to one power supply, or if the distance between
the power supply and the node is great, carefully consider the maximum current and voltage needed to satisfy the specifications at the node’s power
supply connectors and terminals.
2. Power supply from the backup power supply is given priority. Consider the
following points when designing a system.
a) Turn ON the backup power supply before turning ON the power supply to
the PC and computer.
b) The communications data will be corrupted in the instant when the backup power supply is turned ON or OFF.
c) To make sure that the node bypass function is operating when the power
supply to the PC or computer is OFF, use a separate backup power supply that is not connected to the PC or computer.
d) Always use a separate backup power supply. Do not use the same supply as the I/O power supply, motor power cables, or control power cables.

What Are Data Links?
A data link is a function that automatically exchanges the data in predetermined
areas between nodes (PC ↔ PC or PC ↔ Computer) on one network. Data links
can be created freely among CS-series PCs, C200HX/HG/HE PCs, CV-series
PCs, and IBM PC/AT or compatible computers.
Two data link areas, area 1 and area 2, can be set in the Board.
SYSMAC LINK data links can be set in two ways: manually or automatically.
• Data link areas can be manually set by inputting each node’s data link table
using the SYSMAC LINK Support Software or the FinsGateway’s SLK Data
Link Setting Utility. Data link tables are created to define the data links. The
configuration of the data links can be set freely with manual settings.
• Data links can be set automatically from a Programming Device. With automatically set data links, each node has the same sized send area.
Either the automatic or the manual setting method must be used throughout the
network. The two methods cannot be combined in the same network. The following rules apply to these two methods of setting data links.
1, 2, 3...
1. The data links in area 1 and area 2 can be used simultaneously.
2. The settings (starting words and send area size) for areas 1 and 2 are completely independent. The send/receive order is the same for areas 1 and 2.
3. It is not necessary for the Board to participate in the data links.

• Each node’s send area size and location can be allocated freely.
• It is possible to change the order in which data is received from the other
nodes.
• Nodes can be set as send-only or receive-only.

• Use a Programming Device (such as a Programming Console) to set the automatic data link mode in the startup PC’s PC Setup or DM parameter area.
• The CIO or LR Area can be selected for area 1 and the DM Area can be selected for area 2.
• A computer cannot be used as the startup node if the data links are being automatically set.
• A computer can only participate in the data links if the data links are being automatically set.

Setting Data Links
5-2-1 Selecting Manual or Automatic Settings
The data link mode (manual or automatic) is specified by using a Programming
Device to set the data link mode parameter in the startup PC’s PC Setup in the
DM Parameter Area.
Note
1. The data link mode can be selected only with a SYSMAC LINK Unit. Refer to
the SYSMAC LINK Units Operation Manual (W202/W376) for more details.
2. Data links must be set manually when the SYSMAC LINK Support Board
has been set as the startup node.
3. The data link mode can be set in the data link startup node only. The data link
mode setting is determined by the data link mode of the startup node even if
the data link mode settings of the nodes participating in the data links are
different from the settings in the startup node.
4. In manual setting, a data link table must be set in the data link startup node
and in automatic setting, automatic data link setting parameters must be set
in the data link startup node. Data links will not be started unless the settings
are correct.
5-2-2 Manual Setting

3, 2, and 1 starting from the data link starting word address. When the
local node address is 1, data will be received from node 3, received
from node 2, and then sent from the last area.
Note
Note
1. Always include the local node in the node refresh order.
2. When the node address of a node is omitted from the node
refresh order, data will not be received from that node.
1. The actual range of addresses in the CIO/LR and DM Areas depends upon
the PC being used. Refer to the PC’s Operation Manual for details on the
actual data area ranges.

Starting and Stopping Data Links
The data link must be started after data link areas have been created. Use any of
the methods described below for the startup node to start and stop data links.
These methods are the same for both manually and automatically set data links.
Note The data link mode (manual setting or automatic setting) and data link method
are determined according to the data link setting in the startup node. In the startup node, set a data link table in the case of manual setting and data link automatic setting parameters in the case of automatic setting. If the settings are incorrect, the data link will not start.
! Caution
Check the following items before starting data links. If incorrect data link tables
or parameters are set, injury may result due to unexpected operation of the system. Even if the correct data link tables and parameters have been set, do not
start or stop data links before verifying that there will be no adverse influence on
the system.
• Manually Set Data Links
Check the data link tables in each node participating in the data link to see that
they are correct.
Be sure that data link tables are deleted from nodes that are not participating in
the data links.
• Automatically Set Data Links
Set the appropriate settings in the data link startup PC’s DM parameters or
CPU Bus Unit system setup area.

from ON to OFF.
Note
1. Refer to the SYSMAC LINK Units Operation Manual (W202/W367) for details on starting and stopping data links using a Programming Device or ladder program.
2. The data in the DM Area is retained even when the power is turned OFF.
Therefore, settings can be made in the DM Area in advance so that the data
links will start as soon as the power is turned ON.
When a CV-series PC is being used, specify the Start Bit in the Holding Area.
We recommend turning ON the Start Bits in multiple nodes that are participating in the data link so that the data links will start even if the startup node
is down. The same data link mode must be set in these nodes. Also, the
same data link settings must be set in these nodes when automatic settings
are being used for the data links.

5-3-3 Using the SYSMAC LINK Unit’s DIP Switch (C-Series Units Only)
Data links can be started turning with the Start Bit on the DIP switch on the front
of a C-series SYSMAC LINK Unit. The data links will start when the Start Bit is
turned from OFF to ON or is already ON when power is turned ON. The data links
will stop when the Start Bit is turned from ON to OFF.
Note
1. Refer to the SYSMAC LINK Units Operation Manual (W202/W367) for details on starting and stopping data links using the Unit’s DIP switch.
2. If the DIP switch’s Start Bit can be turned ON in advance so that the data
links will start as soon as the power is turned ON.
We recommend turning ON the Start Bits in multiple nodes that are participating in the data link so that the data links will start even if the startup node
is down. The same data link mode must be set in these nodes. Also, the
same data link settings must be set in these nodes when automatic settings
are being used for the data links.
5-3-4 Using FINS Commands
Data links can be started and stopped by sending the DATA LINK START and
DATA LINK STOP FINS commands from a node on the SYSMAC LINK to a node
that is in the data links.

Section
Checking Data Link Status
5-4
5-3-5 Data Link Timing Precautions
When the data link table’s communications cycle time is not being calculated automatically, set a fixed communications cycle time that is long enough. If the setting is too short, it will not be possible for 3G8F7-SLK11/21 SYSMAC LINK PCI
Support Boards and CS1-series SYSMAC LINK Units to participate in data links.
Furthermore, the data links will not start if the communications cycle time setting
is too short and a SYSMAC LINK PCI Support Board or CS1-series SYSMAC
LINK Unit is being used as the startup node.
If a timing error such as the one above occurs, the LNK indicator will be flashing
quickly. At the same time, a “data link communications cycle time setting error”
with error code 021D will be recorded in the error log.
Calculating the Minimum Communications Cycle Time
Use the following equation to estimate the minimum communications cycle time
(TMIN) that can be set:
TMIN =
+
+
+
+
Maximum node address × 0.01
Number of polled nodes × 0.25
Number of linked nodes × 0.161
Total number of data link area words × 0.01
5.322 ms
The communications cycle time is expressed in ms units and fractions are
rounded off.
Error Log Contents
The following error log entry will be recorded if a “data link communications cycle
time setting error” occurs.

2. When a communications error occurs in the local node or it is separated
from the network, the local node retains the most recent status information it
received for the other nodes in the network.
5-4-3 Checking by Manipulating Bit/Word Status
Although the data link function itself may be operating correctly, the data link
areas may have been input incorrectly.
After you have confirmed that the data link function is operating normally, check
to see whether or not the data link is operating as intended, i.e., check to see if
the desired bits/words data is being transferred to the intended words at other
nodes.
Change the contents of a bit or word in a data link send area using a Programming Device or the user program and check whether the change is reflected in
data link areas of other nodes as intended.
The contents of the data link areas set on the local node for the SYSMAC LINK
Support Board can be read and written using the memory monitor program of the
FinsGateway. For details refer to the FinsGateway online help.
5-5
Data Link Performance
When precise timing is required, it will be necessary to know the time required for
to send and receive data through data links and the exact timing when the data is
exchanged.
Data Link Communications Cycle
In a SYSMAC LINK network, the data link service takes priority and the communications cycle time is fixed even if FINS message communications (instructions
such as SEND, RECV, and CMND) are being used simultaneously.

When the communications cycle time varies due to noise or other factors, use
the Support Software to set a fixed communications cycle time between 5 and

62
Number of polled nodes:
4
Number of event frames allowed: 10
Number of linked nodes:
32
Total number of data link words: 2,000
• Coaxial System:
T (ms) = 62 × 0.085 + 10 × 0.654 + 4 × 0.75 + 32 × 0.056 + 2,000 × 0.01
+ 1.322 ms
= 37.924 ms
→ 38 ms
• Optical System:
T (ms) = 62 × 0.1115 + 10 × 0.77 + 4 × 0.75 + 32 × 0.056 + 2,000 × 0.01
+ 1.322 ms
= 40.727 ms
→ 41 ms
The communications cycle time (present value and maximum value) can be
read or set with the Support Software or a command.
Note
1. Refer to Section 8 Communications Timing for details on the network parameters.
2. The data link may no operate correctly if the communications cycle time is
changed to a value shorter than the value that was automatically set by the
system.
3. If the LNK indicator on the front of a CS1W-SLK11/21 SYSMAC LINK Unit is
flashing quickly (about 10 times/second), either change the data link table’s
61
Section
Data Link I/O Response Time
5-6
communications cycle time setting to automatic calculation or set a longer
manual setting.
Changing the
Communications Cycle
Time
When the communications cycle time is set to automatic calculation, the communications cycle time can be changed by changing the network parameters
(maximum node address, number of event frames allowed, number of polled
nodes) with the Support Software. The communications cycle time is set to automatic calculation, the communications cycle time will change just after the network parameters are changed.
The following table shows the default values and setting ranges of the network
parameters.
Network parameter
Maximum node address
Default value
62
Setting range
2 to 62
Number of event frames allowed 10
5 to 255
Number of polled nodes
1 to 62
4
If the result of the following formula is positive, the communications cycle time
will be reduced. If the result is negative, the communications cycle time will be
increased. The units are ms and fractions are rounded off.
Coaxial System
Change (ms) =
(Old max. node address – new max. node address) × 0.085
+ (Old no. of event frames – new no. of event frames) × 0.654
+ (Old no. of polled nodes – new no. of polled nodes) × 0.75
Optical System
Change (ms) =
(Old max. node address – new max. node address) × 0.1115
+ (Old no. of event frames – new no. of event frames) × 0.77
+ (Old no. of polled nodes – new no. of polled nodes) × 0.75
Example Calculations
The example calculations are based on the following changes to the network parameters:
Maximum node address: 62 → 16
Number of event frames: 10 → 13
Number of polled nodes: 4 → 5
• Coaxial System
Change (ms) = (62 – 16) × 0.085 + (10 – 13) × 0.654 + (4 – 5) × 0.75
= 1.198 ms
→ 1 ms
• Optical System:
Change (ms) = (62 – 16) × 0.1115 + (10 – 13) × 0.77 + (4 – 5) × 0.75
= 2.069 ms
→ 2 ms
Note
5-6
1. If there are any nodes in the network with node addresses higher than the
maximum node address set in the network parameters, those nodes will be
unable to join the network or communicate through the network.
2. If the number of event frames setting is too small, the FINS message communications that can be executed in one communications cycle (such as the
SEND, RECV, and CMND instructions, echoback tests, and remote monitoring) will be overly restricted during data link operation and may end in errors.
3. If the number of polled nodes setting is too small, it will take too long for a
node to join the network when a Unit is reset or the PC’s power is turned ON.
Data Link I/O Response Time
When the SYSMAC LINK Support Board’s data link function is being used, there
is a time delay from the time the data link area of one node is changed until this
62
Section

change is reflected in the data link area at another node. This time delay is called
the data link I/O response time.
5-6-1 Computer to PC
In the following diagram illustrating the maximum data link I/O response time, a
CS-series PC is used for the PC (node #2) and the PC’s cycle time is greater
than or equal to the communications cycle time.

There are two points shown in the diagram above where processing is delayed.
1, 2, 3...
1. Data exchange occurs just after the computer at node #1 receives the token
that gives it the right to send data, so processing is delayed about one communications cycle time until the data is transferred in the next data exchange.
2. The data link transmission just misses the PC’s data exchange at node #2,
so processing is delayed about one PC cycle until the data is read into the
PC during the PC’s next data exchange. (If the cycle time of the PC at node
#2 is longer than the communications cycle time, the delay would be approximately two PC cycles.)
Note
1. The I/O response time may be increased by noise or other factors.
2. The data send processing time for the area marked by the asterisk (*) in the
diagram will be affected by the processing capacity of the computer that is
used.
3. The communications cycle time may fluctuate.
4. For details regarding the time required for data exchanges between the
SYSMAC LINK Unit and the PC, refer to the SYSMAC LINK Units Operation
Manual (W202/W367).

Introduction
A message service is a command/response system used for data transmission
between nodes on a network, i.e., computer to computer, PC to computer, or
computer to PC. The message service can also be used to control operations,
such as mode changes. The message service is implemented by executing from
the user program the library functions for sending or receiving messages.
6-1-1 Message Service Specifications
Communications from an computer are executed according to the specifications
shown in the following table.
Item
Direction of transmission
Data length
Data content
Specifications
1:1
Message transmission or reception
1:N
Message transmission (broadcast)
522 bytes max. (including FINS header)
Any command/response data can be sent or received.
Depends on the message being sent.
6-1-2 Message Service Functions
FINS commands can be sent to specified nodes and FINS responses can be
received by executing C library functions from the user program to send and receive messages.
Functions
Features
Sending Messages
This library function and driver call send command/response data.
SlkSendFins library
function
(See note.)
Can be issued with respect to any Units at a PC, or to the Support Board or user
program at a computer.
Mainly used for sending FINS commands and responses. The FINS commands
and responses enable various types of control, and allow the status to be read.
Data is prepared according to a fixed format in the program and sent by executing
SlkSendFins.
No special program is required at the receiving end if FINS commands and
responses supported by the receiving Unit are used.
When sending data to the computer with a user program, a program that can
process the received data is required.
When a response to a command is returned, a program for reading and analyzing
the response is required.
Receiving Messages
These library functions and driver call receive command/response data.
SlkRecvFins library
function
Data received by the SYSMAC LINK Support Board is read.
Mainly used for receiving FINS commands and responses. The FINS commands
and responses enable various types of control, and allow the status to be read.
Data is received by executing SlkRecvFins, and it is analyzed by the program
according to a fixed format.
A program is required for analyzing the data that is received.
A program is required for preparing and sending responses when commands
requesting responses are received.
Note Using SlkSendFins or SlkRecvFins to send the “MEMORY AREA READ” and
“MEMORY AREA WRITE” FINS commands for PCs is equivalent to executing
the SEND and RECV ladder-diagram instructions.

FINS Command/Response Format
This section explains the format of the FINS commands and responses specified by the “SlkSendFins” library function.
When actually sending or receiving message service data, the contents specified by the library function parameters are attached as a header. When the message service is used, however, there is normally no need to pay special attention
to headers.
6-2-1 Headers
Although parameters are used to designate the source, the destination, and other required information, there are some cases where a header must be manually
added before the command code. Refer to the operation manuals for individual
systems to determine if a header is required. The header format described below is attached before the command code and the other parameters described
for individual commands in the rest of this manual.

The main response code (MRES) in the first byte classifies the response and the
sub-response code (SRES) in the second byte indicates details under the
MRES classification.
If bit 7 of the first byte is ON, a network relay error has occurred. Refer to 6-4-2
Network Relay Errors for details on troubleshooting the error.
If bit 6 or 7 of the second byte is ON, an error has occurred in the PC or computer
returning the response. Refer to the operation manual for the device returning
the response for details when troubleshooting the error.
6-4-2 Network Relay Errors
A network relay error will occur whenever a command cannot reach the destination. These errors can occur for several reasons: 1) Data was not successfully
passed between two Link Units, 2) Data was not passed successfully between a
Link Unit and another Unit, such as the PC’s CPU Unit, or 3) The destination of a
gateway does not exist. In any case, the Unit that was not able to transfer data
will return a response indicating a network relay error.
Bit 7 of the first byte of the response code will be ON if a network relay error has
occurred. When this happens, two more bytes of data will follow the response
code to indicate the location of the error. This information, along with the response code, should enable you to track the error.

Relay Errors
78
A relay error indicates that the command did not reach the Unit to which it was
sent. There are two types of situation in which this can occur. Example 1 (below)
shows a situation in which a relay error occurs when data cannot be transferred
from one Communications Unit to another in an interconnected network. In Example 2, the relay error occurs because either the specified destination node or
the next relay node does not exist.
Section
Response Codes
6-4
In the two diagrams, the numbers indicate the following:
(1) The transmitted data fails to be received.
(2) The relay error and response code are returned to the command
source.
In this example, data cannot be transferred between SYSMAC LINK Units due to
some cause such as a routing table error.

What is Network Interconnection?
Network interconnection enables commands and responses for the message
service to be sent and received across multiple networks, including FA and OA
networks. The four networks listed below can be interconnected to achieve this.
FA Networks
• Controller Link Networks
• SYSMAC NET Link Networks
• SYSMAC LINK Networks
OA Networks
Ethernet Networks
7-1-1 Interconnecting SYSMAC LINK Networks

• Communications across bridges or gateways can include up to three networks, including the local network (data generating network).
Network 1 (local network)
Network 2
Network 3
Although 2,012 bytes of data (including the header) can be sent and received
through a Controller Link Network, the maximum amount of data is limited by any
network the data passes through, i.e., the network with the the smallest capacity
will determine the limit.
If, for example, data passes through a SYSMAC LINK network as shown in the
figure, the amount of data sent and received from the SYSMAC LINK is limited to
552 bytes (including the header) because the SYSMAC LINK Network can only
handle that many bytes.
See the manual for the network you are using in order to determine the maximum amount of data for each network.
7-2
Routing Tables
Routing tables that define the communications path from the SYSMAC LINK
Unit on the local PC to the network connected to the destination PC must be
created in order to send and receive data across networks.
Creating Routing Tables
The routing table consists of a local network table and a relay network table.
Local Network Table
The local network table lists the unit numbers and corresponding network addresses for the SYSMAC LINK Unit and Support Board unit numbers.

1. The unit number is set between 00 and 15 using the rotary switch on the front
panel of CV-series and CS-series SYSMAC LINK Units, and is the same as
the operating level for C200HX/HG/HE PCs. For a SYSMAC LINK Support
Board, the unit number is 16 less than the unit address (i.e., the Communications Unit number: 16 to 31) set for the Board in the FinsGateway settings.
2. The network address is the address of the network connected to the Unit
(between 1 and 127). The address is set when the local network table is
created.
A relay network table provides the node and network addresses corresponding
to the initial relay point (first point the data must go to) en route to a target network (end network) not directly connected to the local PC. The table traces the
route from the relay point to the end network.

Network Parameters
This section explains how to use SYSMAC LINK Network communications and
how to adjust the network parameters to match the system.
8-1-1 SYSMAC LINK Communications
The token bus method is used for communications in the SYSMAC LINK Network. With this method, a piece of data called a “token” is passed between the
various nodes in the network. The only node that can transmit data at any given
time is the one that currently holds the token, thereby preventing interference or
conflicts in the transmission of data within the network.
The token travels from in node-address order beginning with the node with the
lowest node address, without regard to the order in which the nodes are connected. When the token reaches the node with the highest address, it is passed
back to the node with the lowest address to start the cycle over again. If a node
has data to send, it will send that data and then pass the token to the next node. If
the node has no data to send, it will just pass the token to the next node.
Polling Node
Each SYSMAC LINK Network always has a Unit that controls communications
within the network. This Unit is called the “polling node.” Normally, the node that
has the lowest node address in the network is the polling node. All Units at nodes
other than the polling node are called “polled nodes.” The polling node controls
the token, checks the network, and performs other relevant tasks. Should the
polling node break down, the node with the next lowest node address is automatically selected as the polling node to prevent the entire network from shutting
down.
Note There are times when the node with the lowest node address will not be the polling node depending on the order in which the nodes are started, models, settings, and node status.
8-1-2 Communications Cycle
The “communications cycle” is the cycle for repeating SYSMAC LINK Network
processing. The time required for one communications cycle is called the “communications cycle time,” and each communications cycle is divided into a “token
cycle” and a “polling cycle” as shown in the following diagram.
Communications cycle
Token cycle
Polling cycle
Communications cycle
Token cycle
Polling cycle
Token Cycle
The token cycle is the period during which the token is sent from the polling node
to the nodes in order and returned to the polling node. During this cycle, any
nodes with data to send will send that data. Data link data will also be sent during
this cycle.
Polling Cycle
The polling cycle is the period during which the polling node checks the status of
the nodes in the network. The polling node checks whether each node is actually
participating in the network, whether there are any new nodes participating, and
so on, and notifies all the nodes of the results of the check.
8-1-3 Network Parameters
Network parameters are also used to control network operations. Network parameters are read from the polling node and distributed to all other nodes when
96
Section
Network Parameters
8-1
the SYSMAC LINK Network is started. In this way, all nodes on the network always have the same network parameter settings. If nodes are connected to the
network halfway during network operation, the network parameter settings will
also be distributed to these nodes when they are connected. The following three
network parameters can be specified.
Maximum Node Address
This parameter specifies the maximum node address of nodes to be checked by
the polling node. The default is 32 for Wired Networks and 62 for Optical Ring
Networks Reducing the setting of this parameter reduces the number of nodes
checked by the polling node and can thus avoids unnecessary check operations. However, if the network contains nodes with node addresses greater than
the setting of the parameter, these nodes will not be connected to the network.
No. of Polled Nodes Per
Communications Cycle
This parameter specifies the number of nodes to be checked (polled) by the polling node during each polling cycle. The default is 4.
Increasing this setting increases the communications cycle time, but reduces
the time required to recognize that nodes have been removed from or added to
the network. On the other hand, reducing this setting shortens the communications cycle time but delays a network response when a node is disconnected
from or connected to the network.
No. of Event-frames per
Communications Cycle
This parameter specifies the maximum number of event frames (communications other than data links, such as message service transmissions) that can be
transferred during a communications cycle. Specify a value in units of 128 bytes.
The default is 10 (128 10 = 1,280 bytes).
Increasing this setting increases the communications cycle time but allows for
more event communications such as the message service. If this setting is too
low, event communications will be restricted and errors will occur.
See 5-5 Data Link Performance for the actual effects of network parameter
changes on communication cycle times.
8-1-4 Specifying Network Parameters
Set the network parameters from the FinsGateway’s SLK Data Link Setting utility. This section describes only the allowable setting range for each network parameter. Refer to the FinsGateway online help for setting procedures.
The following table shows the setting range and default for network parameters.
Network parameter

Maximum node address
2 to 62

Number of polled nodes per communications cycle
1 to 61

No. of event-frames per communications cycle

The network parameters become valid immediately after being set.
Note
1. Always stop the data link before changing network parameters.
2. Specify a value for the maximum node address that is equal to or greater
than the highest node address in the SYSMAC LINK Network.

Error Log
Information on errors that occur in the SYSMAC LINK Support Board is recorded
in the Board’s RAM or EEPROM. The entries that are stored in EEPROM will be
retained even when the computer is turned OFF or reset.
The error log can be read or cleared using a Programming Device (FinsGateway
or Controller Link Support Software) or the message service.

Cleaning and Inspection
9-4-1 Cleaning
Conduct the following periodic cleaning to keep the SYSMAC LINK Support
Board in optimum condition.
• Wipe the Unit with a dry, soft cloth daily.
• If glue, vinyl, or tape is left on the Board for long periods of time, it will stain.
Remove these items during cleaning.
! Caution
Do not use volatile solvents such as benzine or paint thinner, or chemical cloths
for cleaning. They will damage the quality of the coating on the Board.
9-4-2 Inspection
SYSMAC LINK Support Boards must be inspected on a regular basis to ensure
correct operation. Inspections should be conducted once every 6 to 12 months.
If the Board is subject to extremes in temperature or humidity, inspections
should be conducted on a more regular basis.
Tools and Equipment Need for Inspection
The following tools and equipment will be needed to perform inspection and adjustments.
• Assorted flat-blade and Phillips screwdrivers
• Circuit tester or digital voltmeter
• Industrial-grade alcohol and clean cotton cloth
• Synchroscope
• Pen-chart recording oscilloscope
• Thermometer, hygrometer
• Optical tester

Handling Precautions
The SYSMAC LINK Support Board is a Network device. If the Board is damaged, it will affect the entire Network, so always ensure repairs are undertaken
immediately. We recommend that you have a spare SYSMAC LINK Support
Board on hand so that repairs may be conducted quickly.
9-5-1 Replacing the Unit
Observe the following precautions when replacing the Board.
• Always turn OFF the power to the computer before replacing the Board.
• Check that the new Board is not faulty.
• If you suspect that a poor connection is the cause of a malfunction, clean the
connector terminals using a clean, soft cloth and industrial-grade alcohol. Remove any lint or threads left from the cloth, and remount the Board.
• When returning a faulty Board for repairs, always attach a detailed fault report
to the Unit and return to you nearest OMRON outlet as listed at the back of this
manual.
Note In order to prevent faulty operation be sure to turn off the power to all nodes before replacing the Board.
9-5-2 Replacing the Board
Note
112
1. When replacing the Board, do not reconnect that node to the Network before
carrying out the procedures listed below. In particular, a node with a low
node address setting will become the polling node and communicate the initial network parameter status to other nodes, so there is the chance that network parameters in the entire Network will be damaged.
2. The data link table, network parameters, and routing table are stored in the
SYSMAC LINK Support Board’s EEPROM. When the Board has been replaced, make these settings again before starting operation.
The following procedure can be used to automatically set the network parameters in EEPROM from other nodes operating on the network. The data link tables
will need to be reset from the FinsGateway’s SLK Data Link Setting utility.

1. Turn OFF the power supply to the computer containing Board to be replaced.
2. Detach the communications cables attached to the SYSMAC LINK Support
Board to be replaced and remove the Board.
3. Set the new SYSMAC LINK Support Board’s ID switch to the same setting
that was set on the previous Board.
4. Mount the SYSMAC LINK Support Board in the expansion slot of the computer and connect the communications cables.
5. Turn ON the power supply to the computer where the Board was replaced
and open the FinsGateway settings.
6. Use the following procedure to set the Board as a polled node.
a) Click the Basic Tab in the FinsGateway Settings.
b) Click the Drivers Icon.
c) Select SLK (PCI) and click the Properties Button.
d) Select the Board to be set and click the Change Button.
e) Click the Driver Tab in the SYSMAC LINK (PCI) Lists Dialog Box.
f) Remove the check from the setting for the polling unit.

7. Use the following procedure to start the SLKPCI-UNIT service from the
FinsGateway Settings so the Board will participate in the network.
a) Click the Basic Tab in the FinsGateway Settings.
b) Click the Services Icon.
c) Select SLKPCI-UNIT and click the Start Button.
8. Using the SLK Data Link Setting Utility in the FinsGateway or the SYSMAC
LINK Support Software, read the network parameters and make sure the
Network is operating normally.
9. Using the SLK Data Link Setting Utility in the FinsGateway, register data link
tables and routing tables in the new Board.
10. Change the Board to the polling node from the FinsGateway Settings, reversing the procedure in step 6., above. The RUN and INS indicators should
light on the Board. The LNK indicator may also light.
11. Check that the data links are operating normally by using the SLK Data Link
Setting Utility in the FinsGateway.
Note The following procedure can be used to start the SLK Data Link Setting Utility in
FinsGateway.
1, 2, 3...
1. Click the Basic Tab in the FinsGateway Settings.
2. Click the Networks Icon.
