Working Principle:
The PM802F executes control tasks in a deterministic real-time environment. It communicates with distributed I/O stations over fieldbus networks, processes control logic, and exchanges data with higher-level SCADA/DCS systems. Redundant configurations ensure continuous operation during hardware failures.
Installation Requirements:
- Mounting: DIN rail or rack mounting.
- Battery: Install battery before first power-up.
- Network: Configure IP addresses and fieldbus parameters.
- Software: Use Control Builder for programming.
Usage Precautions:
- Battery Replacement: Replace battery within specified time to prevent data loss.
- Redundancy: Ensure both CPUs are synchronized and tested.
- Cooling: Maintain adequate airflow.
- ESD: Use ESD protection during handling.
