Hi Dear, I just found out that Ignition 8.3.6 has module referencing issues on tag value changed event. This is the situation: i do have modules like: [image] on console script i can reference those module without any error: [image] but i put the same lines of code inside the tag value chan…

I just want to make sure that we are all understanding each other, because, at least to me it is unclear if you have this project set as the gateway scripting project or not. Here is what we know about your set-up: You are trying to use these scripts in a Tag Change Script. The scripts are define…
