I am using Lookout 6.2. Whenever the software starts up it loads two values, that are consistently wrong, into my PLC setpoint registers. I have Lookout configured to save the state file every 60 minutes. The two items in question are POTs that are set up as remote connections to the PLC register. My research indicates that remote connections are not saved in the state file. If this is true then I don't know where these values are originating. Any ideas?

Have had a similar issue.
Modbus TCP site using Symblic Links and Remote URL for a pot or switch.
If the "config" process is open, it works fine most of the time (rarely the Latch Delay causes issues). After we close the "config" process and leave the Modbus driver process running (IO limits...), the value will hold for sometime, but will sometimes and at random change to 0/Off.
There is no function in the PLC to set/reset these setpoints.
If we do not open the "config" process, the values will never change.
