Duplex Settings in the PLC Setup

Note
2. Ensure that the cable does not exceed its maximum bending radius.
3. Use the following procedure to use data links.
a. Set the transmission path format, data link manual/automatic setting,
and data link status storage format using the software switches in the
DM parameters area of the CPU Unit.
b. Register the data link tables if using manual setting. If automatic set-
ting is used, set the data link automatic setting parameters.
c. Turn ON the Data Link Start/Stop Bit (software switch in bit 0 of the DM
parameters area of the CPU Unit) for the duplex node Controller Link
Units (CS1D system).
In CS1D Systems with Controller Link Units used in duplex operation, set the
duplex node as a startup node for data links (Data Link Start/Stop Bit in the
CS1D System CPU Unit is turned ON). If the duplex node is not set to be a
startup node for data links (Data Link Start/Stop Bit in the CS1D System CPU
Unit is OFF), and the relevant node is operating as a polling node, the net-
work's data links may stop if an ACT/STB (active/standby) switchover error
occurs.
In the PLC Setup on the CX-Programmer, select Options - Duplex Settings.
Click the Duplex Settings Tab and click the checkbox next to the unit number
for the Duplex Communications Units.
Example: Duplex Settings for Communications Units with Unit Number 0
For details on settings other than duplex settings for Communications Units or
the PLC Setup, refer to the CS-series Duplex System Operation Manual
(W405).
1. Duplex settings for Communications Units can be performed with CX-Pro-
grammer Ver. 3.0 or later.
2. Connect the CX-Programmer to the active CPU Unit when transferring the
PLC Setup settings to the CS1D. The settings cannot be transferred to the
CPU Unit if the CX-Programmer is connected to the standby CPU Unit.
(Only reading is possible.)
3. After changing PLC Setup settings, enable the changes by resetting the
PLC's power supply.
