ResetIn input

This edge-triggered input evaluates the signal of a control device connected to the function block for a manual reset request.

Data type: BOOL
Initial value: FALSE

Connection: Connect this input to the signal of a reset button connected to the Safety PLC (value TRUE or FALSE). Constant TRUE or FALSE values are not permitted.

If the function block is activated (input Activate = TRUE), the possible values at this input lead to the following function block behavior:

Value Description

FALSE The control device for resetting is not triggered.

Edge FALSE>TRUE The control device for resetting has been triggered:

If the function block is parameterized for the evaluation of the rising edge (RisingEdge = TRUE), resetting is requested. If input OperationStop = TRUE and the function block detects no error, the reset signal is output at the ResetOut output.

If the function block is parameterized for the evaluation of the falling edge (RisingEdge = FALSE), resetting is not yet requested. No reset signal is output at the ResetOut output. If the monitoring of the request signal duration is additionally activated (EdgeMonitoring = TRUE), the timer for the monitoring of the MinEdgeTime and MaxEdgeTime time is started.

Edge TRUE > FALSE The control device for resetting has been released:

If the function block is parameterized for the evaluation of the rising edge (RisingEdge = TRUE), no resetting is thus requested. The falling edge at the ResetIn input is then not evaluated and no reset signal is applied to the ResetOut output.

If the function block is parameterized for the evaluation of the falling edge (RisingEdge = FALSE):

If the monitoring of the request signal duration is not activated (EdgeMonitoring = FALSE), resetting is requested. If input OperationStop = TRUE and the function block detects no error, the reset signal is output at the ResetOut output.

When the monitoring of the duration of the request signal is activated (EdgeMonitoring = TRUE), the function block checks whether the falling edge has occurred within the time slot set by MinEdgeTime and MaxEdgeTime. If so, resetting is requested and the reset signal is output at the ResetOut output (if OperationStop = TRUE). When the falling edge does not occur within this time slot, the function block detects an error and the Error output switches to TRUE. In such a case, no reset signal is output at the ResetOut output.

Value	Description
FALSE	The control device for resetting is not triggered.
Edge FALSE>TRUE	The control device for resetting has been triggered: If the function block is parameterized for the evaluation of the rising edge (RisingEdge = TRUE), resetting is requested. If input OperationStop = TRUE and the function block detects no error, the reset signal is output at the ResetOut output. If the function block is parameterized for the evaluation of the falling edge (RisingEdge = FALSE), resetting is not yet requested. No reset signal is output at the ResetOut output. If the monitoring of the request signal duration is additionally activated (EdgeMonitoring = TRUE), the timer for the monitoring of the MinEdgeTime and MaxEdgeTime time is started.
Edge TRUE > FALSE	The control device for resetting has been released: If the function block is parameterized for the evaluation of the rising edge (RisingEdge = TRUE), no resetting is thus requested. The falling edge at the ResetIn input is then not evaluated and no reset signal is applied to the ResetOut output. If the function block is parameterized for the evaluation of the falling edge (RisingEdge = FALSE): If the monitoring of the request signal duration is not activated (EdgeMonitoring = FALSE), resetting is requested. If input OperationStop = TRUE and the function block detects no error, the reset signal is output at the ResetOut output. When the monitoring of the duration of the request signal is activated (EdgeMonitoring = TRUE), the function block checks whether the falling edge has occurred within the time slot set by MinEdgeTime and MaxEdgeTime. If so, resetting is requested and the reset signal is output at the ResetOut output (if OperationStop = TRUE). When the falling edge does not occur within this time slot, the function block detects an error and the Error output switches to TRUE. In such a case, no reset signal is output at the ResetOut output.
