4.3 Reset Input
This section describes the function for clearing the values of the Touch devices by means of external input.
●
Function Description
This function clears execution of the Touch control devices by means of an external input, such as a control panel
switch. The normal external inputs of the Touch are set as reset inputs.
If a reset input is ON, the ladder program or FBD program stops during execution and all control devices and general
errors are cleared, except for special internal relays and special data registers. When a reset input is set to OFF, the
ladder program or FBD program executes from the top.
To set the reset input to OFF and execute the ladder program or FBD program once again, it is necessary that M8000
is ON and that stop inputs are OFF (if a stop input is set).
If these conditions are not satisfied, then even if the reset input is OFF, program execution will remain stopped and
the ladder program or FBD program will not execute.
The external inputs that can be set as reset inputs are I0 to I7.

4 Designate an external input (ex. I1) as a reset input.

This concludes configuring the settings.
If I1 is set to ON after a ladder program or FBD program is downloaded, these programs will stop and the value of the
control device will be cleared.
