EdgeMonitoring input

This input specifies whether the duration of the request signal at the ResetIn input is to be monitored or not.

The monitoring of the request signal duration is only possible when the function block evaluates the falling edge of the request signal (RisingEdge = FALSE). The function block signals an error when the EdgeMonitoring and RisingEdge parameters are TRUE at the same time.

Data type: BOOL
Initial value: FALSE

Connection: Connect this input to a variable or constant.

Value Description

TRUE The signal for the reset request at the ResetIn input is monitored whether the falling edge occurs within the time slot set at the MinEdgeTime and MaxEdgeTime inputs.
The function block signals an error (output Error = TRUE) when the falling edge does not occur within this time slot.

FALSE There is no time monitoring of the request signal.
