Chapter 8 - Fieldbus communication (option)
8:1.3 DeviceNet
The DeviceNet protocol is a fieldbus protocol that provides full control and status
information on the softstarter as well as reading and writing of parameters.
Through the fieldbus, it is possible to start and stop the motor, perform jog,
sequence start, read out currents and frequency, acquire information about
protections, warnings, faults and much more.
See chapter 7 “ Settings and configuration” for programming the inputs /
outputs.
Before the DeviceNet fieldbus can be put into operation, the following param-
eters must be set in the softstarter:
• Parameter Fieldbus Ctrl set to Yes
• Parameter Fieldbus Type set to other
• Parameter Fieldbus Addr set to a free communication address.
Warning!
If the motor is running and the parameter Fieldb Ctrl is changed from No to
Yes, this will stop the motor (fieldbus control overrides the programmable
inputs).
If the motor is not running and the parameter Fieldb Ctrl is changed from
Yes to No, this might start the motor if there is a start signal present.
For installation and commissioning of the DeviceNet fieldbus, see document
2CDC193002D0201 available at www.abb-control.com/html/products/
soft_strs.html.
For the set-up of the PLC, specific software is required and is available on
the softstarter web pages. Look under the documentation-link named
Software. If you need help or advice, please contact your local ABB office.
