Not sure if anyone else has seen this behavior.
I am having a problem that when a controller (PR1) comes back online in Ignition my integer values report zero (0) for one scan - it is possible non-integer values do the same, but I haven’t checked those.
You can see in the historian entries below:
Unplugged PR1 network cable
22:03:44.2780 the data quality goes bad, value shows last known value of 3 - as expected
Plugged PR1 network back in
22:04:04.7830 the value goes to 0 with good quality - not so good
22:04:06.0580 the value goes to 3 with good quality - correct
Is this an issue with me, IA, Cirrus Link, or Opto22?
