Write time to third party opc server

Ignition

Hi!
I have a question regarding writing tags to third-party opc server like Kepserver, ABB 800xA and similar.

I have script that does a system.tag.writeblocking call with 89 tags in the list. The function call returns after about 90-100s, over a second for each tag. Is this normal behaviour or do I have an issue in my setup?

What version are you on? At some point a performance regression writing to OPC tags via system.tag.writeBlocking was introduced, and it has since been fixed.

8.1.35

Yeah, that's one of the affected versions. Upgrade and see if your issues persists.

Thanks Kevin, an upgrade to 8.1.37 worked.
Now the write was done in 424ms

Do you know what version the regression was introduced?

It was present in 8.1.34 and 8.1.35.
