6.2.3 When the MP2300S Acts as Master (I/O message communication function is
used)
This section explains how to communicate with the MP2300 message receive function (MSG-RCV) using the
MP2300S I/O message communication function.
Fig. 6.6 Message Flow with MP2300 when I/O Message Communication Function Is Used
„ I/O Message Communication
I/O message communication implements out 1:1 communication.
In addition, you can read and write only the holding register in the case of “Communication Protocol Type: Extended MEMO-
BUS” used in the communication with MP series.
When you communicate with multiple remote devices, or when you need to read a coil state or input relay, or change a coil state
as well as read/write a holding register, use the message transmit function (MSG-SND).
