AC450 system message mtype 26, code 1

Hello.
Does anyone have a more specific explanation of this system message?

Is it an object in a HMI-display pointing at a renamed DB-object? If so, how can I get more specific info about which?

mtype 26
Code 1
address = H'83 = D'131, = trace number
Task = DCBAB00 = AI object handler.
Data1 = 0 and 1 = parameter value.
Data 2 = H'00504645, No explanation
