Working Principle
The PO700HU collects data from FBM modules via the fieldbus, executes user control programs, and dispatches control commands to actuators. It synchronizes data and coordinates with host computers and other control stations via the 100Mbps Ethernet network.
Installation Requirements
- Must be installed in designated control station rack slots.
- Fiber optic communication cables must be spliced or terminated according to specifications.
- Ensure redundant power supplies are connected correctly.
Usage Precautions
- Strictly prohibited to forcefully remove the processor module while the system is running.
- Regularly perform redundancy switching tests to ensure the backup module is in a ready state.
- Firmware upgrades must be strictly conducted according to manufacturer guidelines.
