Working Principle
The module continuously scans field input signals, executes control algorithms to derive output values, and synchronizes status with other nodes in the system via a redundant network to achieve global coordinated control.
Installation Requirements
- Maintain control cabinet ambient temperature strictly below 60℃.
- Keep fiber optic connections clean and avoid bending them beyond their minimum radius.
- Correctly configure redundancy jumpers or DIP switches.
Usage Precautions
- Regularly inspect the synchronization status indicator lights on redundant modules.
- Avoid unsecured usage in high-vibration environments.
- Store spare modules in moisture-proof and anti-static conditions.
