6.2 Operating controls
Display
While in operation, the controller is in the
operating level.
The display is divided into two sections. Each
section is assigned to one controller.
The default assignment is as follows:
− Left display: Controller [1]
− Right display: Controller [2]
The controlled variable (actual value), error
signal, set point and manipulated variable
(output) are displayed for each controller in
the default setting.
Depending on the configuration, status
alarms of the digital inputs and outputs can
be shown. For control modes with just one
controller, further signals can be displayed in
five rows in the additional display.
Infrared interface
The infrared interface is used to exchange
data between the controller and the TRO-
VIS-VIEW software (see the 'Operation' sec-
tion).
DIP switches
Î See Fig. 6-1.
The DIP switches are used to initially select
whether an input is to accept a current/volt-
age signal (mA, V) or a resistance signal
(Pt 100, Pt 1000, potentiometer). The DIP
switches are located at the side of the hous-
ing.

A difference is only made between the keys

this case, the keys on the left are used to op-
erate the controller on the left display and
the keys on the right are used to operate the
controller on the right display.
The function of the keys varies depending on
the level/menu which is active (see Table
