The Citect Help says that a separate port
must be declared for each CV PLC. Not only a separate Citect Port
must be used but also a separate TCP/UDP port in the special
options must be used. The default TCP/UDP port for the OMRON
CV500-ETNO1 Ethernet card is 9600. If you have more than one
Ethernet card on the network, each card must have a unique port
number. This number is then used in the special options section of
the Ports form in Citect. e.g. PLC 1 --> -I192.168.50.101 -P9600
-U, PLC 2 --> -I192.168.50.102 -P9601 -U. |
