3.8 List of Input/Output Signals From/To the Programmable controller CPU
The QD51 (-R24)'s input/output signals are explained.
The following I/O signal assignment is based on the case where the start I/O No. of the
QD51 (-R24) is "0000" (installed to slot 0 of the main base unit).
Device X is an input signal from the QD51 (-R24) to a programmable controller CPU.
Device Y is an output signal from the programmable controller CPU to the QD51
(-R24).
The input/output signal list for the programmable controller CPU is shown in the
following table.

1 The multitask execution start signal (X0B) is a signal that announces whether
access to the QD51 (-R24) by the programmable controller CPU is possible or
not. Use it as the system program interlock signal. (It goes ON when a BASIC
program is run.)
2 If the QD51 (-R24) system down signal (X0D) goes ON, start up the
programmable controller CPU again. (Power supply reset, CPU module, QD51
reset)
