3.4 I/O Signals for Programmable Controller CPU

3.4.1 I/O signal list

The following lists the MES interface module I/O signals to the programmable controller
CPU.
The following I/O signal assignment is based on the case where the start I/O No. of the
MES interface module is "0000" (installed to slot 0 of the main base unit)
If the MES interface module is mounted other than slot 0, see the list with changing the I/O
signals by those of the mounted slot.
Device X indicates an input signal from the MES interface module to the programmable
controller CPU and device Y indicates an output signal from the programmable controller
CPU to the MES interface module.
