G.2 Message Receive Function (MSG-RCV)
A-102
( 5 ) Option (PARAM03)
A unique value is output for each communication device.
Not used for the MELSEC protocol.
( 6 ) Function Code (PARAM04)
Received function code is output.
The following table lists the function codes available when using the MELSEC protocol.
Note: 1. B: Bit type, W: Integer type
2. AnCPU dedicated commands are not supported. Commands for extended file register are not sup-
ported.
( 7 ) Data Address (PARAM05)
A data address requested from the transmission side is output.
( 8 ) Data Size (PARAM06)
The read/write data size (number of bits or words) requested from the transmission side is output.
( 9 ) Remote CPU Number (PARAM07)
Refer to G.2.4 Function Setting and Parameter Details for MEMOBUS and Extended MEMOBUS Protocols.
