SIEMENS TIA PORTAL Understanding Rising and Falling Edge
In this tutorial, we explain the concept of Rising Edge and Falling Edge detection in PLC programming using Siemens TIA Portal for Siemens S7-1200 and Siemens S7-1500 PLCs.
Edge detection is used to detect a change in a signal state rather than the continuous signal. It allows the PLC to execute an action only once when the signal changes.
