Posted 1 May 2019 Hey, I recently started trying my hand at creating function blocks. At the moment I'm trying to create a PID function block, however I keep getting this error: "ERROR: Variable does not have enough size." No idea why it does this. Can anyone help?

Posted 1 May 2019 (edited) I don't see where you have PID_I defined. Is it large enough? Edited 1 May 2019 by IO_Rack Share this post Link to post Share on other sites
