Application Precautions
• Turn ON the terminating resistance switch only for the nodes at both ends
of the network and turn OFF the switch for all other nodes.
• Turn OFF the power of all the nodes on the network before connecting or
disconnecting a cable.
• Use the specified cable only.
• Set the same baud rate for all nodes on the same network.
• Be sure to set routing tables for CVM1 and CV-series PLCs. When a
CVM1 or CV-series PLC is connected to the network, set routing tables at
all the nodes.
Note
Routing tables are not required if all of the CVM1 and CV-series CPU Units if
the Controller Link Network were manufactured on or after May 1996.
Note
The manufacturing date can be determined from the four-digit lot number on
the side of the CPU Unit.
