Description
ABB CI830
Technical Specifications:
- Protocol: PROFIBUS DP-V1 Master.
- System: ABB S800 I/O and AC 800M.
- Baud Rate: Up to 12 Mbit/s.
- Physical Interface: 9-pin D-sub connector.
Functional Features:
- Integrated DP Master: Eliminates the need for external PROFIBUS master devices.
- Cyclic and Acyclic Data: Supports both cyclic I/O data exchange and acyclic parameterization/diagnostics.
- Bus Diagnostics: Advanced diagnostic capabilities for PROFIBUS network health.
Application Scenarios:
- Connecting PROFIBUS drives, valves, and analyzers to the AC 800M system.
- Distributed control stations requiring direct fieldbus integration.
- Retrofitting PROFIBUS devices into modern DCS architectures.
Performance Parameters:
- High-Speed DP-V1: Supports advanced PROFIBUS features for fast parameterization and alarm handling.
- Deterministic Cyclic Data: Guaranteed I/O update times.
Material Composition & Structural Characteristics:
- Form Factor: S800 I/O communication unit.
- Connectors: Standard PROFIBUS D-sub and S800 bus connectors.
Working Principle:
The CI830 operates as a Class 1 DP Master, cyclically polling configured PROFIBUS slaves and exchanging I/O data. It translates this data into the S800 I/O bus format for the AC 800M controller. Acyclic requests for parameter changes or diagnostics are handled on-demand without disrupting cyclic data flow.
Installation Requirements:
- PROFIBUS Wiring: Use certified PROFIBUS cables with proper termination and grounding.
- GSD Files: Import the correct GSD files for all connected slave devices into Control Builder.
- Addressing: Assign unique PROFIBUS addresses to all slave devices.
Usage Precautions:
- Baud Rate Matching: Ensure all devices on the PROFIBUS network are configured with the same baud rate.
- Cable Length: Adhere to PROFIBUS cable length specifications based on the selected baud rate.
