Gateway Scripting Project not recognized on tag value change script


After restarting Ignition we frequently see this error for many tags. “Devices” is a script library and is set as the Gateway Scripting Project. They seem to go away after a while but I was curious as to why they occur. Shouldn’t a tag value change script have access to the Gateway Scripting Project? We are running 8.1.19.

Could you possibly show where the script project is and also where it is being used?


I would expect it happens when the global scripting project or one of its parent projects is edited and saved, causing those scripts to be reloaded. That could leave a small window where a tag event can’t load the script.

Use a Gateway Tag Change Event script (in a project) instead of a tag event (on the tag) if you wish to avoid this.
