PROFIBUS DP – Supplementary manualfor NORD Frequency Inverter SK 2xxE
8 Subject to technical amendments BU 0220 GB-0912
1 General information
Various technology options are available for Getriebebau Nord frequency inverters. General information
regarding these can be found in the relevant main manual of the frequency inverter series (e.g. Manual
BU0200 for the SK 200E frequency inverter series). Further information concerning special technology
options (e.g. the field bus module) is included in the relevant supplementary operating instructions.
This PROFIBUS DP documentation contains supplementary descriptions concerning the PROFIBUS DP
options for the SK 200E frequency inverter series.
The description of other optional modules (e.g. CANopen) is dealt with in other supplementary documentation.
In order to set up communication with PROFIBUS DP, either an internal Customer Unit or an external
PROFIBUS DP Technology Unit (according to the particular application) must be installed and connected.
The PROFIBUS DP bus system
A large number of different automation devices can exchange data with frequency inverters using
PROFIBUS DP. PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in
serial bit mode. PROFIBUS DP is primarily used for communication between sensor and actuator where
system response needs to be very fast. PROFIBUS DP is used where the time for rapid and complex
communication between the individual devices is critical. PROFIBUS DP is a suitable alternative to
expensive 24-volt parallel signal transmission and transmission of measured values. This type of
PROFIBUS, which is optimised to speed, is used for instance for operating frequency inverters on
automation devices.
PROFIBUS communication is standardised and specified in the international standards IEC 61158 and
IEC 61784. Application and planning aspects are specified and documented in the guidelines of the
PROFIBUS users´ organisation (PNO). This ensures intercommunication between devices from different
manufacturers. Data exchange is specified in DIN 19245 Part 1 and 2 and application-specific upgrades in
Part 3 of this standard. Within the European field bus standardisation process, PROFIBUS is integrated into
the European field bus standard EN 50170.
