Description
Technical Specifications:
- System Compatibility: ABB AC 800M / System 800xA.
- Function: CPU processing or network interface gateway.
- Communication: Supports multiple industrial fieldbus protocols.
- Form Factor: Standard modular industrial card.
Functional Features:
- Protocol Translation: Converts proprietary ABB bus data to standard fieldbus formats.
- Data Buffering: Manages high-volume data traffic to prevent network congestion.
- Redundancy Support: Compatible with redundant controller architectures.
Application Scenarios:
- Expanding communication capacity in large DCS networks.
- Integrating third-party PLCs into the ABB control environment.
- Remote I/O station interfacing.
Performance Parameters:
- Throughput: High-bandwidth data processing.
- Latency: Deterministic communication delays.
Material Composition & Structural Characteristics:
- Construction: Rugged industrial PCB with backplane connectors.
- Indicators: Status LEDs for power, communication, and fault conditions.
Working Principle:
The PP846 intercepts data packets on the internal bus, processes or translates the protocol headers, and routes the payload to the appropriate destination network or controller.
Installation Requirements:
- Configuration: Assign unique network addresses and routing tables.
- Cabling: Use certified ABB communication cables.
Usage Precautions:
- Compatibility: Verify hardware revision compatibility with the master controller.
- Termination: Ensure proper bus termination if acting as a network endpoint.
