Remarks

I/O signals of the AnyWire DB A20 master module
I/O signals of the master module indicate the state of the module, and are used as command
output. This is different from using as ON/OFF signals of the remote station for MELSEC-I/OLINK.
The "n" in the table is the start I/O number of the master module which is determined according to
the mounted position and modules mounted before the master module.
When the start I/O number of the master module is "X/Y10"
