The ABB infrastructure and network devices for PROFIBUS facilitate creating a robust infrastructure for fieldbus and ease for maintenance and expansions. Support for PROFIBUS DP line redundancy helps to increase availability of critical equipment. ABB's fieldbus components are ideally prepared for their specific use in the field. With the available set of devices following advantages are provided:
- Connection of non-redundant slave devices to redundant PROFIBUS DP lines
- Transparent gateway between PROFIBUS DP and PROFIBUS PA
- The bus segment is protected against communication errors and shortcircuits
- EEx i field devices can be connected during operation
- No further T boxes or distribution boxes are needed
