Handling Precautions
Section 10-7
2.
Detach the communications cables and backup power supply cable at-
tached to the Controller Link Unit to be replaced and remove the Unit.
3.
Mount the new Controller Link Unit in the PLC and connect just the backup
power supply cable. (Leave the backup power supply OFF.)
4.
Set the unit number, node address, baud rate, and the terminating resis-
tance for the new Unit to the same settings as the previous Unit. (Refer to
SECTION 4.)
5.
Turn ON the power to the PLC with the Controller Link Unit that was re-
placed.
6.
Use a Programming Device to turn ON (set to 1) the new Controller Link
Unit’s polling node/polled node control bit (bit 15 of the following word).
Turning this control bit ON sets the Unit as a polled node.

7.
Turn OFF the power to the PLC with the Controller Link Unit that was re-
placed.
8.
Connect the communications cables. (Refer to SECTION 3.)
9.
Turn ON the backup power supply to the Controller Link Unit that was re-
placed.
10. Turn ON the power to the PLC with the Controller Link Unit that was re-
placed.
11. Using the Controller Link Support Software, read the network parameters
and verify that the Network is operating with the correct settings.
12. If the data links are being used but not activated automatically, start the
data links from the data link startup node.
13. Check that the data links are operating normally by monitoring them from
the Controller Link Support Software.
14. Use a Programming Device to turn OFF (set to 0) the new Controller Link
Unit’s polling node/polled node control bit (bit 15 of the following word).
Turning this control bit OFF sets the Unit as a polling node.

Online Replacement in CS1D Systems
In CS1D Systems, if a Controller Link Network is used in token-ring mode,
Controller Link Units can be replaced without turning OFF the power for the
PLC (online replacement).
• Online replacement is possible only for Controller Link Units (including
models without “-V1” at the end) mounted to a CS1D PLC with the trans-
mission path format set to token-ring mode.
• Online replacement is possible in both CS1D Duplex Systems and Sim-
plex Systems.
• In token-ring mode, because of transmission path duplication, Units can
be replaced without interrupting communications. In token-bus mode,
because there is no transmission path duplication, the network is split
during Unit replacement.
• When using Controller Link Units in duplex operation, the standby Unit will
switch to active mode during online replacement of the standby Unit. (It
will leave the network temporarily before rejoining.) The influence of the
node disconnection can be reduced to a minimum. (Refer to 8-5 Switch-
ing Time for Duplex Units.) For Controller Link Units that are not used in
duplex operation, the node will remain disconnected from the network
throughout online replacement.
Online replacement is performed using a Programming Console (CQM1-
PRO01/CQM1H-PRO01/C200H-PRO27).
