 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-

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).
