Figure 3-7 Overview of input parameters
Input signal extension
A short input signal can be extended compared to the actual input signal with the help of this
parameter. This enables reliable transfer to the controller (compensation of bus transfer
times and processing time in the controller).
Input signal delay
You can set a debounce time for the inputs in order to achieve interference immunity.
Input n signal
You can use this device parameter to specify whether or not the input level of the digital
inputs should be saved.
● Retentive, i.e. latching mode (edge evaluation)
Regardless of the input signal present, the action can be deactivated again by another
event.
● Non-retentive, i.e. jog mode (level evaluation)
This input action remains active for as long as the input is activated.
