What would be one possible cause of stop code 8180H or 80H in a Unity Quantum HSBY system ?
If the default Watch Dog Timer value of 250 milliseconds is lowered on a Quantum HSBY system, there exists the possibility
that the Quantum PLC will stop with an error code 8180 during initial start up. The condition occurs because the scan time
will increase as the Primary attempts to copy the logic to Standby during start up, this results in the WDT expiring and a
no end of logic error because the tranfer was incomplete.
Lowering the default WDT setting is not a recommended practice for HSBY systems.
