Uncertain_InitialValue on only 1 tag group

Ignition
1

Hello,

I am setting up a new Rockwell PLC (ControlLogix V35). I have one tag UDT where some of its values are showing up fine and some of its values are showing up as Uncertain_InitialValue. This is the only tag that is doing this. I've read about the PLC being idle but with all of my tags working aside from this one I don't think that is the case. It doesn't seem to be the Ignition version (8.1.4) or Rockwell PLC version (V32) where this was common. Does anyone have any other solutions?

Make sure the UDT members have the correct external read/write access applied.

I got it. The tag groups were incorrect.
