Contents of Operation/Setting of FX
Node A and Node B exchange data by using one message.
Node A
Node address: 128
Message 1
Tx Message
Message 2
Rx Message
Message 1 of Node A and Node B are configured as transmit (Tx) messages. Node A uses PGN 45312 for its
Tx message, Node B uses PGN 45568 for its Tx message.
Message 2 of Node A and Node B are configured as receive (Rx) messages. Node A Rx message receives
the Tx message of Node B, and Node B Rx message receives the Tx message of Node A.
The baud rate and node address setting, as well as the configuration of message 1 and message 2, are done
in the PLC program.
