I/O Area; Number Of Error Addresses; Value Of Error Addresses - Mitsubishi Electric MELSEC-Q Series User Manual

4.2.1

I/O area

The slave module requires "Address setting" which specifies the start number assigned in the transmission frame.
The settings are configured in 2-point unit. The addresses of both an input slave module (e.g. input remote I/O module)
and an output slave module (e.g. output remote I/O module) start from "0", and the area later than that number is
occupied corresponding to the number of module points.
Ex. Assignment of two 8-point input remote I/O modules

The number of error IDs (addresses) is entered in 2000
Any value from 0 to 128 is entered.
4.2.3

Value of error addresses

If a disconnection or a slave module error is occurred, the error address is written to 2001
the lowest address up to 128 addresses.
This value is maintained until the disconnection error is reset or until the power is turned off.
Buffer memory address
The detected error address is classified and displayed in the memory and on the monitor according to the table below.
Hexadecimal display address
