6.2.2 When the MP2300S Acts as Slave (ladder program which uses a MSG-RCV
function)
The MP2300S can communicate with only one master when using the automatic receive function.
To communicate with more than one master, use a ladder program with a message receive function (MSG-RCV) at the
MP2300S end. You can use the message receive function (MSG-RCV) as well as the automatic receive function by
keeping connections separate from each other.
This section explains how to communicate with an MP2300 message transmit function (MSG-SND) using the
MP2300S message receive function (MSG-RCV).
