9 Web server in force mode
9.1 Activating the 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 out-
put process data and the u-remote station will
process them for all unforced output channels.
However, forced output channels will ignore any
process data and behave according to forced val-
ues.
Input process data are transferred all the time, in-
dependently whether they are simulated by forc-
ing or read via the physical inputs.
If the force mode is activated without an estab-
lished eld bus connection the eldbus interface
will be deactivated for the duration of forcing. An-
other 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
precongure the station prior to commissioning, even if
sensors have not yet been connected. To do so, you must
change the operating mode of the web server.
▶ Click Force/Enable.

The web server is now in force mode, recognisable by the
signal red bar above the station view. Forced channels are
marked with a red border line.

If the connection between web server and cou-
pler is interrupted, the force mode is stopped im-
mediately.
