6.4.2 When the MP2300S Acts as Master (I/O message communication function is
used)
This section explains how to carry out the communications between CPU and the MELSEC Q series using the
MP2300S I/O message communication function.
Fig. 6.13 Message Flow with MELSEC Q series when I/O Message Communication Function Is Used
 Caution
I/O message communication is 1:1 communication.
In addition, you can read and write the registers below using inter-CPU communication when “Communication Protocol Type:
MELSEC” is used in the communication with the MELSEC series.
• Bit device register - - - - X, Y (read only), M, B
• Word device register - - - D, W, R
Note: A bit device register reads or writes on a per-word (16 bit) basis.
When communicating with multiple remote devices.
To carry out a fixed buffer/random access buffer communication when reading/writing registers other than those mentioned
above, use the message transmit function (MSG-SND).
