I have a situation that I need some assistance with. I’m not much of a coder and I’ve been tasked with troubleshooting a project someone else wrote. We’ve got a UDT for each workstation. On that UDT are tags for some call buttons, Button 1, 2, 3, etc. On those call button tags are tag event scripts…

If the tag diagnostics on the tags are not showing any error, then, your best bet is to implement a logger with a try…except structure. Something like: import java.lang.Exception logger = system.util.getLogger("yourLoggerName") try: #script to attempt except: java.lang.Exception, e: log…

Thanks for your reply. I got back to this today. I added your code around the code I’m trying to troubleshoot and tested the buttons. I’m not seeing anything in the logs though. Can I assume that an exception in these circumstances would be something like, say, a DB query looking for a column that …

If SQL throws and error, it would be caught and printed to the log. If you are not seeing any errors in the log, this means 1 of 2 things. 1.) The code is not being executed. You have already stated that the tag values are changing, and we can be fairly sure that Ignition is raising the value cha…

I think the issue is the latter you described. It’s executing and the query is just coming up empty. Since the query is attached to a UDT and the same UDT is used across several stations, why we’re getting the results we want on several other stations but not this one is confusing. I’m trying to fig…

I tried to use the code in post 2, and I got errors.

[image] Zach_Larson: got errors. That's because that code has the same extra colon I mentioned elsewhere.

In addition to what @pturmel has mentioned about the extra ':', you also have not used the full script neglecting to import the Java type, and not defining the logger.

See my mention of PythonAsJavaException in the new topic.

Every time I attempt to use an example try except with a logger, it throws errors, and I get instructions that I don't understand. I tried using chatGPT and it starts using a different syntax that throws different errors. Is there a spot that explains it well?
