Description
ABB SPNPM22
Technical Specifications:
- Processing Power: Dedicated microprocessor for local data manipulation.
- Memory: Sufficient RAM and flash for local logic and buffering.
- I/O Interface: Connects to Symphony I/O bus and local submodules.
- Update Rate: Deterministic local scan rates.
Functional Features:
- Local Processing: Executes scaling, linearization, and simple logic locally.
- Data Buffering: Stores historical data during communication interruptions.
- Signal Conditioning: Advanced filtering and validation of raw I/O signals.
- Diagnostics: Comprehensive self-testing and submodule monitoring.
Application Scenarios:
- Complex signal processing for specialized instruments.
- Local control loops that must operate independently of the main controller.
- High-density I/O applications requiring local data aggregation.
Material Composition & Structural Characteristics:
- Design: High-density industrial PCB.
- Mounting: Standard Symphony Plus rack mount.
- Connectors: Backplane and loop interface connectors.
Working Principle:
The SPNPM22 receives raw data from local I/O submodules, applies configured processing algorithms, and sends the refined data to the main controller. It also receives setpoints and logic commands from the controller to execute locally.
Installation Requirements:
- Configure processing parameters and logic in the engineering tool.
- Ensure adequate backplane power for the module and connected submodules.
- Set the correct module address.
Usage Precautions:
- Do not overload the module with excessive local logic.
- Verify that processed data ranges match controller expectations.
