Timeout (s): Permits the setting of the time within which the override function must be ended from 10 s to infinite.
Override Mode: Makes it possible to configure the start of the override function (pulsed or state triggered).
With OverOut: Makes it possible to activate an active override signal output (active if high).
With Request: Makes it possible to activate a signal output (active if high) to indicate that the override function can be activated.
Manual Reset:
Ì If the RESET input is active (TRUE), the OUTPUT output on the function block is enabled.
Ì If the RESET input is not active (FALSE), the OUTPUT output on the function block follows the override request.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual reset, the system only checks the
signal transition from 0 to 1. With the monitored reset the double transition from 0 to 1 and then back to 0 is checked.
