Posted 25 May 2020 I'm using simple function block, one input and one output, like in this example: Problem I have is how to call function block and use inverted (NOT) value , ie instead 5.01 I need to use NOT (5.01) . Of course I could create new symbols that are inverted values of actual inputs but i'm trying to avoid that, number of addresses is significant. Share this post Link to post Share on other sites
Posted 26 May 2020 Change the function block. Add a second boolean input that is called Invert. If it is true, it inverts the input if not, it does not. Or if it always needs to be inverted, just change the FB to invert it all the time. Share this post Link to post Share on other sites
Posted 27 May 2020 OK, thank you. Then I'll just create two different FBs. Share this post Link to post Share on other sites
