sNetID : AmsNetID of the PC.
iPLCPort : Port number of the PLC runtime system (AMSPORT_R0_PLC_RTS1 = 801,
AMSPORT_R0_PLC_RTS2 = 811, AMSPORT_R0_PLC_RTS3 = 821, AMSPORT_R0_PLC_RTS4 = 831).
iUPSPort : Port number for reading the UPS-State (default value is 16#4A8).
tTimeout : Timeout for the execution of the QuickShutdown.
eUpsMode : eUpsMode defines, if persistent data need to be written and if a QuickShutdown needs to be
executed.
The default value is eSUPS_WrPersistData_Shutdown, means with writing of the persistent
data and then a QuickShutdown. See E_S_UPS_Mode.
ePersistentMode : Mode for the writing of the persistent data. Default value is SPDM_2PASS.
tRecoverTime : Time which will be waited after a power failure (in case of UPS modes without shutdown) to
go back to the status PowerOK.
