Hi guys

I am running 8.0.2 version with opto22 module 4.0.2 version. I am trying to write to a single integer or string in opto22 through ignition but something weird happening and i cant write even through quick client. It says that it is writing succesfully when i am trying to write through quick client but nothing is written actually. When i am trying to write from pac control its ok but i cant through ignition.

The most weird is that i managed to write in the past but now i dont.

Any suggestions??

@ntsib I am having the same issue while running Ignition version 8.0.14 and opto module version 4.0.2. Did you ever resolve this issue?
