Programming
In the eSUPS_CheckPowerStatus mode only a check is performed as to whether a power failure has
occurred. If this is the case, the function block only switches back to the PowerOK state after the expiry of
tRecoverTime (10s).

Description
AmsNetID of the controller (type: T_AmsNetId)
Port number of the PLC runtime system (851 for the first PLC
runtime system, 852 for the second PLC runtime system, ...). If
you do not specify a port number, the function block then
automatically determines the port of the PLC runtime system.
Timeout for writing of the persistent data or the quick shutdown.
Defines whether persistent data are to be written and whether a
quick shutdown is to be executed. The default value is
eSUPS_WrPersistData_Shutdown, i.e. a quick shutdown is
executed automatically once the persistent data have been
saved. (Type: E_S_UPS_Mode)
Mode for the writing of the persistent data. Default value is
SPDM_2PASS.
Time after which the UPS reverts to the PowerOK status in the
case of UPS modes without shutdown. tRecoverTime must be
somewhat longer than the maximum holding time of the UPS in
order to ensure that the capacitors are fully charged.
Description
TRUE during power failure. FALSE if the supply voltage is
present.
Internal state of the function block (type: E_S_UPS_State)
Description
Internal state of the function block as global copy of
VAR_OUTPUT
For values see E_S_UPS_State
