I guess the alarm expression aspect can't parse the "$" symbol (in 800xA/CHMI800 it is reserved to point on the structures: e.g. $'Root/.../...)
Place your property in the left side of operator to the single quotes to interprete the property as whole ('ST$Pos$stSeld' == true).

Re: [?+]: Compact HMI 800 with Third party OPC
You're correct. Right syntax is "ST$Pos$stSeld"==true
But I don't know why the signal alarm display only one time on Alarm and Events List. After ack. it not appaer any more whether condition changed.
