Setup PC program
(accessory)
The setup PC program is available in German,
English and French for configuring the
instrument. You can use it to create and edit
sets of data and transfer them to the
instrument, as well as read them out from it.
The data can be stored and printed.
Setup interface
The setup interface is integrated into the
JUMO dTRANS CR 02 by default. You can
use it, together with the setup program
(accessory) and a setup interface (accessory),
to configure the instrument.
RS232/RS485 interface
The serial interface is used for communication
with higher-level systems when the Modbus/
Jbus protocol is used.
PROFIBUS-DP
The JUMO dTRANS CR 02 can be integrated
into a fieldbus system according to the
PROFIBUS-DP standard via the PROFIBUS-
DP interface. This PROFIBUS-DP version is
especially designed for communication
between automation systems and distributed
peripheral devices at the field level and is
optimized for speed.
Data is transferred serially based on the
RS485 standard.
Using the project design tool that is included
in the delivery (GSD generator; GSD = device
master file), a standardized GSD file is created
by selecting characteristic device features of
the JUMO dTRANS CR 02. This file is used to
integrate the controller into the fieldbus
system.

Pulse width controller
(output active with x > w and P control structure)
If actual value x exceeds setpoint w, the P controller will control in proportion to the control
deviation. When the proportional range is exceeded, the controller operates with an output level
of 100 % (100 % clock ratio).
Pulse frequency controller
(output active with x > w and P control structure)
If actual value x exceeds setpoint w, the P controller will control in proportion to the control
deviation. When the proportional range is exceeded, the controller operates with an output level
of 100 % (maximum switching frequency).

Math and logic module
The math module makes it possible to
integrate measurement value of the analog
inputs into a mathematical formula so that the
calculated process variable can be displayed.
The logic module can be used, for example, to
link binary inputs and limit comparators with
each other logically.
Up to two math or logic formulas can be
entered with the optional setup program and
the results of calculations can be displayed or
exported via outputs (via PC setup software
only).
