Commissioning
Value Description Features
tBatt Time during which the system is
operated via the battery. Variable, depending on the duration of the
power failure. If tBatt >= tCA the UPS
service irrevocably starts shutting down the
system.
tCA Maximum time on battery voltage
before critical alarm. Once this time has
elapsed the UPS service irrevocably
starts shutting down the system. Configurable in minutes via the Beckhoff
UPS configuration dialog.
If tCA = 0 the UPS service immediately
starts shutting down the system.
tSDtask A time window provided by the UPS
service for a shutdown application
(shutdown task). Not configurable, fixed and limited to a
maximum of 30 seconds.
• NT4: tSDtask = 0 if no shutdown
application was configured and
tSDtask = tSDapp if a shutdown
application was configured.
• All other operating systems: tSDtask
always requires 30 seconds.
tSDapp Time actually required by the shutdown
application (shutdown task). Variable, depends on the features of the
application. Limited to a maximum of 30
seconds. After 30 seconds the shutdown is
irrevocably continued. tSDapp should
always be < maximum of tSDtask.
tTCstop This time is required for stopping the
TwinCAT system. During this time the
UPS service stops all TwinCAT servers. Variable, depends on the number of
configured TwinCAT servers. Limited to a
maximum of 45 seconds. Shutdown
continues irrevocably after 45 seconds.
tTCstop = 0 if TwinCAT is not installed or
has already been stopped beforehand.
tUPSoff Delay time for switching off the UPS.
The actual shutdown of the operating
system starts once the UPS service has
completed all internal shutdown tasks.
Once this time has started the operating
system takes over control and
continues with the shutdown (window
applications and services including the
UPS services are closed and the
system is shut down completely). Once
this time has elapsed the UPS
irrevocably switches off the outputs and
the IPC in order to save battery
capacity. Configurable via the Beckhoff UPS
configuration dialog. The available values
are hardware­specific. tUPSoff should
always be >tSDwin.
tSDsrv Time required by the UPS service for
shutting down internal tasks. tSDsrv =tSDtask +tTCstop
tSDwin Time required by the operating system
for a shutdown. Variable, depends on the number of
running applications that have to be closed.
tDlg For systems without soft power­off
functionality (e.g. NT4): For systems
with soft power­off functionality (e.g.
XP): Variable, depends on the operating system
used, the number of running applications,
the motherboard and the UPS hardware:
tDlg = tUPSoff ­ tSDwintDlg should always
be > 0. You can only influence this value by
the choice of tUPSoff. For systems without
soft power­off functionality the dialog
should be visible at least for a short time
before the UPS switches off the IPC. For
systems with APC­UPS and soft power­off
functionality the IPC should switch off first,
followed by the UPS.
