Selecting Communications Functions
Section 1-3
1-3
Selecting Communications Functions
Select the data link function if alarm or status data (in bits) must be constantly
shared between PLCs or between a PLC and an IBM PC/AT or compatible
computer or if the present value or set value data (in words) must be con-
stantly shared between PLCs or between a PLC and an IBM PC/AT or com-
patible computer.
Select the message service function (SEND/RECV instructions or CMND
instructions) if data (in words) must be sent (or received) from one PLC to
other PLCs in other nodes or from one PLC to IBM PC/AT or compatible com-
puters.

Basic Procedures
Preparation for Communications
1,2,3...
1.
Perform wiring and installation.
• Install the Unit in the PLC.
• Connect the communications cables.
2.
Set the unit number on the front rotary switches.
• 00 to 15 (0 to F: CS-series display is in hexadecimal)
Note When using Communications Units in duplex operation, set the same
unit number for both Units in a duplex pair.
3.
Set the node address on the front rotary switches.
• 01 to 62
Note When using Communications Units in duplex operation, set the same
node address for both Units in a duplex pair.
4.
Connect power to all nodes.
5.
Connect the Programming Device to the PLC.
6.
Make the duplex settings in the PLC Setup.
• Specify the Units used in duplex operation.
• Specify the active Units and standby Units.
Note These settings are required only when Communications Units are
used in duplex operation.
7.
Create I/O tables.
Note When I/O tables for configurations with Communications Units used
in duplex operation are created, the Unit with the lower slot number
will be designated as the active Unit and the Unit with the higher slot
number will be designated as the standby Unit. To reverse this des-
ignation, edit the I/O tables offline and transfer them to the PLC.
8.
Set the transmission path format using software switches in the DM param-
eters area.
• Token-ring mode or token-bus mode
Note This setting is made for Optical Ring Controller Link Units only. (It is
not required for Optical Bus Systems because the token-bus mode is
always used.)
9.
Register routing tables.
Note This setting is required only for connection between networks or
when using CVM1 or CV-series PLCs.
