I am testing out PLCnext Engineer 2026.3 and I notice something strange.
Take a look at the online value of ai_2_IN01 - it shows as channel error with value 16#8002 (open circuit) in the data list of the analog input card, and in the global variable list.
However, in watch window (and logic analyzer), the real value of 16#332F appear just fine. Also actual program code the value seem to be correct.
In earlier versions this value was the same everywhere.
Someone experienced might ask if there is an intermittent error causing the channel to rapidly change between open loop and valid signal, but this is not the case as I am counting every reported channel error and shows in the diagnostics screen of the HMI. It should also appeared in the logic analyzer trend.
As for now I am calling this a bug and waits for either confirmation or that someone points out a gaping hole in my logic
