This section describes the input/output signals of the Q series C24.
The following I/O signal assignment is based on the case where the start I/O No. of the
Q series C24 is "0000" (installed to slot 0 of the main base unit).
Device numbers starting with X indicate input signals from the Q series C24 to the
programmable controller CPU.
Device numbers starting with Y indicate output signals from the programmable
controller CPU to the Q series C24.
The following table lists the input/output signals for the programmable controller CPU.
