G.1 Message Transmit Function (MSG-SND)

A-56

G.1.3 Message Transmit Function Parameter List (Param) Overview

The param of the MSG-SND function has a parameter list structure composed of 17 words. (The value of the Param
itself is the start address (MA, DA) of the parameter list.)
In the parameter list, enter a connection number, function code and its relevant parameter data. Process results and sta-
tus are also output.
When MEMOBUS or non-procedure is used as a communication protocol, the parameter list is as follows:

Note: Parameter details are explained in the parameter details for each protocol type. Refer to the following

items:

G.1.4 Function Setting and Parameter Details for MEMOBUS and Extended MEMOBUS Protocols
G.1.5 Function Setting and Parameter Details for MELSEC Protocol
G.1.6 Function Setting and Parameter Details for MODBUS/TCP Protocol
G.1.7 Function Setting and Parameter Details for Non-procedural Protocol
