6.11.3 External input/output forced on/off
The external input/output can forcibly be turned on/off on the screen opened by selecting [Online] [Debug]
[Forced input output registration/cancellation] in GX Developer.Note1
The information registered for forced on/off can be cancelled by an operation from GX Developer.
(1) Input/output operation when a forced on/off operation is performed
There are three kinds of forced on/off operations: forced on ("Set forced ON"), forced off ("Set forced OFF"), and
forced on/off cancellation ("Cancel it").
Table6.11 shows the CPU module operation when a forced on/off operation is performed.

The CPU module performs sequence program operations
using external inputs.
The CPU module outputs the results of sequence
program operations externally.
