10.10 Web server in force mode
WARNING!
Manipulation of the control unit!
In force mode, the system may be manipu-
lated to such an extent that can result in life-
threatening personal injury and damage to
materials.
Only use force if you are very familiar with the
connected system and know at all times the
consequences that your actions will have!
If the force mode is activated during an estab-
lished eld bus connection a diagnose alarm is
generated. Depending on parametrised alarm
behaviour the PLC can continue to transmit
output process data and the u-remote station
will process them for all unforced output chan-
nels. However, forced output channels will
ignore any process data and behave according
to forced values.
Input process data are transferred all the time,
independently whether they are simulated by
forcing or read via the physical inputs.
If the force mode is activated without an es-
tablished eld bus connection the eldbus
interface will be deactivated for the duration of
forcing. Another eldbus connection can only
be established after the force mode has been
deactivated.
Safety related modules (safe I/O modules and
safe power-feed modules) can not be forced.
The force mode allows you to carry out functional tests or
precongure the station prior to commissioning, even if sen-
sors have not yet been connected.
To do so, you must change the operating mode of the web
server.
▶ Click on Force and enable.
Switching over to force mode
The web server is now in force mode.
When force mode is activated, the screen dis-
play changes – the entire station is highlighted
and outlined in warning colours.
If the USB connection is interrupted, force
mode is stopped immediately.

Open the detail view of the station in force mode
For a better survey we recommend to change to the detail
view. In this view modules can be fade out and in, which is
helpful, especially when working with larger stations.
▶ Click on Force and Station.
