Hi,
Vision Client turns red all over. Looks like it is losing coms every time I add a tag (UDT) or edit a tag(UDT). What could be the issue?
What PLC are you using?
PLC is AB 1756-L85E.
And you mean Ignition UDTs right?
How do you have your tags groups setup?
What does your PLC loading look like?
for how long?
It's normal for that to take a few seconds, depending on how many UDT instances you have.
When you edit a UDT, every instance of the UDT is interrupted while it updates with the changes that were made.
If your changes are scripting edits (not good), use Gateway Tag Change event scripts (best) or have tag change event scripts call gateway scripts (better) and that will allow you to make code changes without interrupting all your UDT instances.
What version of Ignition are you running? v7 would restart all of the UDT instances upon changes to any of the tags within the definition which would cause red overlays like this.
Does it stay red or does it come back?
Are you change tags in the PLC with Studio 5000? If so, then you are losing access to fresh data while Ignition rescans the tags and types in the PLC. (Ignition looks for metadata changes once per minute if set to auto-rebrowse.)
?
What loading is 50%? The Ignition device performance? How many tags, what poll rates, etc. You've given very limited info to receive a relevant response. You didn’t answer are the changes to UDTs in the PLC (which would be offline and require a download, during which Ignition loses connectivity), or are the changes to UDTs in Ignition? How many instances of the UDT types that youre changing. How many elements in the UDT?
