SYSMAC LINK
SYSMAC LINK Units: CS1W-SLK11/SLK21
SYSMAC LINK Support Boards: 3G8F5-SLK21/SLK22
A Basic FA Network with Data Links and Message Communications.
Both Wired and Optical Networks Supported.
An FA network SYSMAC LINK Network supports
data links between PCs or between PCs and
personal computers (data constantly shared over a
given area), as well as communications messages
between PCs or between PCs and personal
computers (i.e., send and receive data when
necessary).
What is the SYSMAC LINK?
The SYSMAC LINK is an FA network that can transfer data among
OMRON Programmable Controllers (CS1-series, C200HX/HG/HE,
and CV-series PCs) and IBM PC/AT or compatible computers. The
SYSMAC LINK supports data links that enable data sharing and a
message service that enables sending and receiving data when
required.

Features
Data Links
Data links allow the constant sharing of data in predetermined data
areas between nodes, between PCs, or between a PC and an IBM
PC/AT or compatible computer on the network. Data links do not require the use of communications programs on the PC (CPU Unit) or
IBM PC/AT or compatible computer. Data written in the send area of
the local node will be automatically sent to the receive area of other
nodes.
Any portions of the I/O area (CIO Area), data link area (LR Area),
and data memory area (DM Area) can be specified as the send or
receive words.
•
Manual Setting
Used for flexible data link processing depending on each system.
Using the CX-Net of the CX-Programmer, individual data link tables
can be set for each node and the data link words can be freely allocated for each node. Send data size per node can be freely set. It is
also possible to set nodes for only send or receive data.
SYSMAC LINK Unit

PC
Number of send words per node: 508 words max. (CIO Area: 254
words + DM Area: 254 words)
•
Number of send and receive words per node: 2,966 words max.
(sum of CIO Area and DM Area)
The data link area can be set automatically or manually.
Automatic Setting
Used for simple data link processing. Data link can be performed by
simply setting parameters in the DM Area of the PC. Send data size
per node is the same for all nodes. All nodes participating in the data
link share the same data.

Message Service
This function controls data transmission with particular nodes, reading or writing of status data, changing of operation modes, etc., by
executing communications instructions on a program. The communications instructions include SEND/RECV instructions for data
transmission and CMND instructions for issuing various commands.
SEND/RECV
The SEND or RECV instruction sends or receives data in an area of
a particular node.
The SEND instruction sends data from an area of the local node and
writes to an area in the designated node.
The RECV instruction requests the designated node to send area
data and writes the data to the local node.
SYSMAC LINK
Product Specifications
CMND
The CMND instruction issues a command to read or write data of
other nodes, control, or read error logs. With the SYSMAC LINK
Unit, OMRON’s command protocol called “FINS commands” is
used.

Flexible Inter-network Connections
• The SYSMAC LINK Network can connect to
other networks
(Ethernet, Controller Link, and SYSMAC LINK) via CVM1,
CV-series, or CS1-series PCs. By installing a Communications
Unit for the Ethernet, Controller Link, or SYSMAC LINK on the
same CS1-series, CVM1, or CV series-PC as a Controller Link
Unit, a message service can be created with nodes in
interconnected networks through this PC. Up to three network
levels are possible.

Coaxial Cable or Optical Fiber Cable Connection
The SYSMAC LINK Units can be connected to the network using
either coaxial cables or optical fiber cables. Select the system that
suits your application.
Features of System Using Coaxial Cable
The 5C-2V Coaxial Cable is used for wiring the SYSMAC LINK Unit
or Board.
Features of System Using Optical Fiber Cable
• Optical Fiber Cable has superior noise resistance, so this
system can provide highly reliable communications even in very
noisy conditions.
•
The communications distance can be up to 10 km in total (1 km
max. between nodes), which allows long-distance or large-scale
networks.
Compatible with Different Node Configurations
• The following SYSMAC LINK Units are available for
communications between different models. It must be noted,
however, that the wired system and optical system cannot exist
in one SYSMAC LINK Network.
The programming and monitoring of other PCs on the network
can be conducted from Programming Devices connected to the
PC’s CPU Unit. Inter-network connections are possible in this
case also and can cover up to three network levels.
Node Bypass (Optical System Only)
With the 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 IBM PC/AT or compatible 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, 24-VDC backup power must be
supplied to the SYSMAC LINK Unit.
RAS
RAS performs real-time monitoring of the network status. If an error
occurs in the network, RAS records and displays the time and contents of the error.
Status Area
•
Data Link Status Area
When the data link function is used, the data link status is
reflected in the data link status area of the PC.
Network Status Area
The network status such as the state of node participation is
reflected in the status area of the PC.

The error log function records contents (codes) and times of errors
that occur in the network into the RAM, or EEPROM in the SYSMAC
LINK Unit.
The recorded errors can be read using the CX-Net of the CX-Programmer or the message service function.
Data Link Settings Using CX-Programmer
You can make data link table settings, monitor the status of data
links, and perform similar operations for the CS1-series SYSMAC
LINK Unit using the CX-Programmer programming software. (You
cannot directly connect the SYSMAC Support Software to a
CS1-series CPU Unit using RS-232C.)
