Working Principle
Acquires field data via a high-speed bus, performs logic and regulation computations using built-in algorithms, dispatches control commands to actuators, and communicates with upper-level computers via Ethernet.
Installation Requirements
- Ensure the rack is properly grounded.
- Avoid direct sunlight exposure and proximity to high-temperature heat sources.
- Secure all wiring firmly to prevent loosening over time.
Usage Precautions
- Strictly prohibit hot-plugging modules.
- Regularly clean control cabinet filters to guarantee adequate heat dissipation.
- Promptly record alarm codes during faults to facilitate troubleshooting.
