Supplementary Manual DeviceNet for NORDAC SK 200E
8 Subject to technical amendments BU 0280 GB
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 DeviceNet documentation contains supplementary descriptions concerning the DeviceNet options for
the SK 200E frequency inverter series.
The description of other optional modules (e.g. CANopen, Profibus DP) is dealt with in other supplementary
documentation.
In order to set up communication with DeviceNet, either an internal Customer Unit or an external
DeviceNet Technology Unit
(according to the particular application) must be installed and connected.
The DeviceNet bus system
DeviceNet allows numerous different automation devices to exchange data with the frequency inverters.
PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in serial bit mode.
DeviceNet is primarily used for communication between sensor and actuator where system response needs
to be very fast. DeviceNet is primarily used where time critical, fast and complex communication between
the individual devices is essential. DeviceNet is a suitable alternative to expensive 24-volt parallel signal
transmission and transmission of measured values. This type of DeviceNet, which is optimised to speed, is
used for instance for operating frequency inverters on automation devices.
