Beckhoff CU8110-0060 Manual page 29

Value Description
tSDapp Time actually required by the shutdown
application (shutdown task).
tTCstop This time is required for stopping the TwinCAT
system. During this time the UPS service stops
all TwinCAT servers.
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.
tSDsrv Time required by the UPS service for shutting
down internal tasks.
tSDwin Time required by the operating system for a
shutdown.
tDlg For systems without soft power-off functionality
(e.g. NT4):
• Time during which the dialog: "It is now safe
to turn off your computer" is displayed.
For systems with soft power-off functionality
(e.g. XP):
• With Beckhoff P24Vxxxx UPS: tDlg = 0, the
UPS switches off the outputs and the IPC
immediately.
• With APC-UPS: Time during the IPC
continues to be supplied with UPS voltage
(standby mode).
tBoot Time required by the operating system during
the boot process until the UPS service is
started.

Properties
• 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.
Variable, depends on the features of the
application. Limited to a maximum of 30 seconds.
After 30 seconds the shutdown continues
irrevocably.
tSDapp should always be < maximum oftSDtask.
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 no TwinCAT is installed or was
already stopped previously.
Configurable via the Beckhoff UPS configuration
dialog. The available values are hardware-
specific.
tUPSoff should always be >tSDwin.
tSDsrv =tSDtask +tTCstop
Variable, depends on the number of running
applications that have to be closed.
Variable, depends on the operating system used,
the number of running applications, the
motherboard and the UPS hardware:
tDlg = tUPSoff -tSDwin
tDlg should always be > 0. This value can only be
influenced throughtUPSoff.
For systems without soft power-off functionality
the dialog should be visible at least for a short
time before the UPS switches off the IPC.
For systems with APC-UPS and soft power-off
functionality the IPC should switch off first,
followed by the UPS.
Variable, depends on the number of applications
and services that have to be started.
