G(P).RDMSG

These instructions read/write parameters from the master station to the remote device station and read out the status.
(A master/local module with a serial number (first five digits) of 10032 or later supports these instructions.)
The instructions can be used with the remote device station, for example NZ2AW1C2AL, that supports the message
transmission function.
