This section explains the I/O signals of the QJ71MT91 for the programmable controller
CPU.
The following table shows the I/O signals of the QJ71MT91.
The following I/O signal assignment is based on the case where the start I/O No. of the
QJ71MT91 is "0000" (installed to slot 0 of the main base unit).
Device X represents an input signal from the QJ71MT91 to the programmable
controller CPU.
Device Y shows an output signal from the programmable controller CPU to the
QJ71MT91.
Refer to the corresponding reference sections for details.
