Built-in Ethernet Communications

6.2.4 When the MP2300S Acts as Master (ladder program which uses a MSG-SND

function)

The I/O message communication function cannot operate any registers other than the holding register (M register).
Note that it can communicate with only one slave.
To communicate with more than one slave, use a ladder program with a message transmit function (MSG-SND) on the
MP2300S side. You can use the message transmit (MSG-SND) function as well as the I/O message communication
function by keeping connections separate from each other.

This section explains how to communicate with the MP2300 message receive function (MSG-RCV) using the
MP2300S message transmit function (MSG-SND).
