1.1 Overview
Features of the PROFIBUS DP modules

Electrically isolated bus interface

Transfer rate: 12Mbit/s

Easy connection, optionally via M12 round plugs or screw terminals

Looping of the PROFIBUS DP via the module

Integrated bus terminating resistor (switchable)

PROFIBUS DP-specific status indication with 2 LEDs on the internal (Customer Unit) and external
(Technology Unit) technology option

DEVICE or FI-specific status indication with 2 LEDs on the internal (Customer Unit) and external
(Technology Unit) technology option

PROFIBUS DP basic functionality as per DP-V0

Acyclic data traffic as per DP-V1

Up to four 24V inputs and two 24V outputs are integrated into the bus module

Direct connection of up to 4 sensors and 2 activators via M12 round plug connectors on the
SK TU4-PBR-M12(-C) version. Visualisation of signal status via LEDs

Transmission and reading of process and parameter data

PROFIBUS DP Gateway solution → up to 4 frequency inverters can be connected to a
PROFIBUS DP module

Up to 122 PROFIBUS DP modules can be connected to the bus. This enables the operation of up to
488 frequency inverters on one bus.

Automatic detection of baud rate and PPO type by the PROFIBUS DP module

"Simultaneous" access by up to 4 PROFIBUS DP masters (1 x DPM1 and up to 3 x DPM2) possible.
The DPM2 masters do not need to be permanently connected to the PROFIBUS DP network for
communication.

Interface (RS232/RS485) for parameter access by means of the SK PAR-3H manual control unit or
NORDCON software via RJ12 connector (Except for SK CU4-PBR. Here parameter access via the
SK 2xxE frequency inverter is possible)

Available as versions for installation in the inverter (IP20) or in a separate housing (optionally
IP55 / IP66)
1.2 Delivery
Check the equipment immediately after delivery/unpacking for transport damage such as deformation or
loose parts.
If there is any damage, contact the carrier immediately and carry out a thorough assessment.
Important! This also applies even if the packaging is undamaged.
