I am presently working on a project for what I am finalizing system architecture, For this I have some queries I would like to share:- 1. Is it possible that I can run a script on Wincc Flex PC Runtime by pressing button over a remote HMI (KTP1000) which is connected in network. 2. Can I run a script with PLC output signal.

For the first part of question, make some flag on PLC. When you press a button on panel, it changes this flag, and WinCC flex will run script on this change. Best regards

plcbug Posts: 68 Rating: (0)	Hey fbelic, I tried it & it works but not in the way I want. It runs script at both positive & negative edge of that bool flag but I want script to run on positive edge only. Is it possible.

fbelic Posts: 327 Rating: (28)	Greetings There are (at least) two ways to do this. First way is to simply add one IF...THEN at the begining of your script, comparing your boolean external flag to TRUE. Put all your code inside IF. Another way is a bit more complicated, but not much. Instead boolean, use integer variable. And instead "Change value" event, use "High Limit". Set some limit to that variable (e.g. 10). So, whenever you want to execute your script, just set it to value larger than your limit (e.g. 100). Best regards
