Hi All,
As many of you have, I had some issues with simply wanting a button that acted as a switch. On each press, to toggle the status of a Boolean variable. The attached flow is what I have now. While this is probably overly complicated, it works well for what we are doing...EXCEPT for the fact that after deploying, each button has to be clicked twice for it to work.
After that initial double click it works fine until deployed again. I read into the nodes from the OPCUA Read to get the current status and continuously be monitoring it and the buttons are accurate and also send to the OPCUA Write node so that it can change the status on click. 1) Does anyone know how I can get it to work on the first click? or 2) Does anyone have a better and more efficient way of doing this?
I forget where but over the past months i have used various examples and kind of made this into my own so any input would be greatly appreciated.
Thanks,
Paul
