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.
