ValueChange script run multiple time

Ignition

Hi everyone,

I have a UDT containing multiple tags. Some tag are OPC tag, other are expression tag. Some tag contains ChangeValue script. It was working fine since a few month.

We got a problem since about 2 weeks. Sometimes, a ChangeValue script execute 2 or 3 times when the value of the tag change only one time.

Any idea?

You could check that newValue is different from oldValue before executing.
