Communicating between OMRON PLCs Section 8-6
Note 1. With CS/CJ-series PLCs, the Communications Port Enabled Flags at bits
0 to 7 in word A202 turn OFF even when the PCMR(260) instruction is be-
ing executed using the ports corresponding to those flags.
2. Before using the sample program as is, confirm that the memory areas
(words and bits) used in the sample program are not already being used in
the user program o r by Special I/O Units.
When the Communications Port Enabled Flag for port 7
is ON, and SEND(090) is not being executed, the trans-
mission execution program will start when execution
condition CIO 000001 turns ON.
Input CIO 120002 remains ON from the start of
RECV(098) execution until completion.
