MaxEdgeTime input
Specification of the maximum duration of the request signal at the ResetIn input.
Data type: TIME
Initial value: #2s
Minimum value: #0.1s
Connection: Connect this input to a time literal, i.e., to a constant of the data type TIME.
The input specifies the maximum duration (in seconds) for which the request signal at the ResetIn input may have the TRUE state. The request signal must switch to FALSE again before this time has elapsed. If this not the case, the function block signals an error (output Error = TRUE). By doing so, the input specifies in combination with the MinEdgeTime input the time slot for the falling edge of the request signal to occur so that the request signal is recognized as valid signal.
The setting value of this input is only relevant when the function block evaluates the falling edge of the request signal (RisingEdge = FALSE) and the duration monitoring of the request signal is activated (EdgeMonitoring = TRUE).
| Hinweis
The time slot set via the MinEdgeTime and MaxEdgeTime inputs must correspond to at least one cycle of the Sicherheitssteuerung. For information on this value, please refer to the corresponding PLC user manual. |
