I'm new to Festo PLC Programming. Can you tell me in ladder diagram, how do I detect falling edge and rising edge in FST 4.21 software? There is no icon in ladder element.

The information about falling and rising edge is presented in the Festo manual file. Access Google Search and then click the Manual from the 4th link listed in the search results. Download and open the PDF file then press CTRL + F to search for the information you need. I have used the file and there were instructions on how to adjust the falling and rising edge.

Note: A compatible PDF reader is required in order to open the PDF file.
