MVP 2023 Joe Tauser Posted April 21 MVP 2023 Report Share Posted April 21 What you've posted looks like a good start to me. I'm guessing you've verified that your "Message" tag is the same length as your "Vklop10" tag. If it doesn't work I'd add both tags to a Watch when you're online with the PLC so you can actually see what's going on. Joe T. Link to comment Share on other sites More sharing options...
