Hi,
I have the problem with Datatype variable.
I created a datatype and I used it for 5 componente (same variables inside the PLCs) but I do not have the same results.
I do not see all variabiles and I have this error in the logs of Ignition: “Error fetching groups.java.lang.NullPointerException”
Please show the complete error with backtrace. Don’t use a screenshot. Instead, copy the text from the wrapper log and paste it here. Use triple backquotes (these: ```) on a line above and again below the pasted text so it will be formatted in a code block.
Also show the OPC Item Path for the affected tags.
I don't think the error fetching groups/users is relevant. That looks like some other problem, happening every couple minutes or so.
I can't tell what's wrong with the affected elements of the UDT.... you'll have to carefully compare every property against the corresponding property of a working tag.
Consider exporting in XML format (one working, one non-working) and posting here as a code block. (Please use the triple back-quotes as requested--not the blockquote function.)
