PI UFL irregular tag updates.

Hi! I'm transfering lines of data from a simulator over a Serial input to PI UFL where the lines update PI tags on the DataServer.

The problem is that it only seems to update the tags when the change in input differs enought from the current tag value.

The reason i think it has with the change in value is because if i make the value increase/decrease more rapidly, the tag updates every second like it should.

For example: I have a value that goes from 17 to 17.5 and back again over the span of 25 seconds, and the UFL is supposed to update the tag value every second, but instead it only updates between every 3-6 seconds.

Is there any way to make it update constantly? (aka, for every second/for smaller changes in value)

(Note: If i set the timestamp to be in the future in the simulator, and then back to current time, all the tags starts to update every second, regardless of if the value has changed untill the connection is broken. It will then go back to irregular updates.)


Thanks in advance! Sam.
