I have the following lines in the wrapper.log over and over, but im not sure what they are or how to fix them. Does anyone have any suggestions on how to track them down and fix them or should i Just leave them alone?

Any ideas where these collisions would take place? Thanks

These should be harmless. Judging by the naming I’d guess they’re coming from the MES instrument module or something like that.

It just means that the scripting functions are being double-registered. I’ll pass it along to the MES guys. If you could let me know what version of Ignition you’re running that would be useful.

Just to get into the possible fix and a full explanation. When you say double registered do you mean that there are two possible methods that could be invoked at

> [@](#):
>
> system.instrument.parse.types.values

And the warning is to indicate that?

No, only one will be invoked. It’s more a warning to the developer doing the registration.
