TRIGGER (SCHMITT TRIGGER)

When the VALIDATE FUNCTION input is set to ON, this function analyses the variations of the VALUE TO BE COMPARED input in relation to the SETPOINT FROM ON TO OFF and SETPOINT FROM OFF TO ON thresholds. When the VALUE TO BE COMPARED input falls below the SETPOINT FROM ON TO OFF threshold the OUTPUT changes to OFF. It remains in this state until the VALUE TO BE COMPARED input rises above the SETPOINT FROM OFF TO ON threshold. At this point, the OUTPUT changes to ON.

In summary, the OUTPUT remains unchanged as long as the VALUE TO BE COMPARED input is between the SETPOINT FROM ON TO OFF and SETPOINT FROM OFF TO ON thresholds.

If the VALIDATE FUNTION input is OFF when the program is started, the output is OFF, regardless of the input values. When the VALIDATE FUNCTION input changes to OFF during program execution, the OUTPUT remains unchanged.

The VALIDATE FUNCTION input and the OUTPUT are digital.

The VALUE TO BE COMPARED, SETPOINT FROM ON TO OFF and SETPOINT FROM OFF TO ON inputs are INTEGER type inputs.
