sNetID : AmsNetID of the controller.
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 via which the UPS status is read (standard value is 16#588).
tTimeout : Timeout for the execution of the QuickShutdown.
eUpsMode : The eUpsMode defines whether persistent data are to be written and whether a
QuickShutdown is to be performed.
Standard value is eSUPS_WrPersistData_Shutdown, i.e. with writing of the persistent data and then
QuickShutdown. See E_S_UPS_Mode.
ePersistentMode : Mode for the writing of the persistent data. Standard value is SPDM_2PASS.
tRecoverTime : Time after which the UPS reverts to the PowerOK status in the case of UPS modes without
shutdown.
The tRecoverTime must be somewhat longer than the maximum holding time of the UPS, since the UPS
switches off even when the voltage returns.

E_S_UPS_State
bPowerFailDetect : True during the power failure; False if the supply voltage is present.
eState : Internal state of the function block, for values see E_S_UPS_State.

E_S_UPS_State
eGlobalUpsState : Internal state of the function block as a global copy of the VAR_OUTPUT eState; for
values see E_S_UPS_State.
