I have a program to take a resistive input in from a fuel level sender, and do a calculation to convert to a percentage and display it on a gauge. The calculation works correctly as I can see it run in my function block, but the HMI will not connect to display the gauge live. Codesys says my gateway is not configured properly but I cannot find how to configure it so that it works. Does anyone have any tips or tricks on how to do this?
