Precautions
Refer to the procedure in the Controller Link Unit operation
manual for replacing the Unit while the system is still operat-
ing, and observe the following precautions.
1) The external power supply must be turned OFF. If
another node is sharing the power supply so that the
power supply cannot be turned OFF only to the Unit
being replaced, a power interruption will be detected,
causing a communications error. Confirm that the power
supply can be turned OFF safety.
2) When the optical cable is removed, a disconnection of
the line will be detected at other nodes.
3) If a Duplex Communications Unit is being used, the
standby Unit will take over and continue communications.
(Pre-V1 Unit do not support duplex operation and cannot
continue communications when replaced. Communica-
tions, however, will be continued at the other nodes.)
4) Set the same unit number and node address on the new
Unit as were set on the Unit being replaced.
5) When the new Unit has been mounted and the online
replacement operation has been completed for it, the set-
tings stored in the CPU Unit will be automatically trans-
ferred to the new Unit.
Refer to the Controller Link Unit operation manual for
replacement procedures and observe the following precau-
tions.
1) The external power supply must be turned OFF to all
nodes before a Unit can be replaced. Communications
will stop for all nodes.
2) Set the same unit number and node address on the new
Unit as were set on the Unit being replaced.
3) When the new Unit has been mounted and the online
replacement operation has been completed for it, the set-
tings stored in the CPU Unit will be automatically trans-
ferred to the new Unit.
Refer to the Controller Link Unit operation manual for
replacement procedures and observe the following precau-
tions.
1) If a CJ1W-TB101 Relay Terminal Block is being used, a
Unit can be replaced without turning OFF the power sup-
ply to all nodes in the network. Communications will stop
for the node of the Unit being replaced.
2) If a Relay Terminal Block is not being used or if the node
of the Unit being replaced is at the end of the network,
power must be turned OFF to all nodes on the network
before replacement is possible. Communications will
stop for all nodes.
3) Set the same unit number, node address, baud rate, and
terminating resistance setting on the new Unit as were
set on the Unit being replaced.
4) When the new Unit has been mounted and the online
replacement operation has been completed for it, the set-
tings stored in the CPU Unit will be automatically trans-
ferred to the new Unit.
Refer to the SYSMAC Link Unit operation manual for
replacement procedures and observe the following precau-
tions.
1) Turn OFF the power supply to all nodes in the network
before replacing the Unit. Because the power is turned
OFF to all nodes during online replacement, communica-
tions cannot be continued.
2) Set the same unit number and node address on the new
Unit as were set on the Unit being replaced.
3) When the new Unit has been mounted and the online
replacement operation has been completed for it, the set-
tings stored in the CPU Unit will be automatically trans-
ferred to the new Unit.
