Working Principle:
The NIOC-02 connects to the AC800M controller’s internal I/O bus. It encapsulates controller data into standard Industrial Ethernet frames and transmits them over the network. Conversely, it receives Ethernet frames from field devices, extracts the process data, and maps it to the controller’s memory space. The dual ports work in tandem to monitor link health and automatically reroute traffic in milliseconds if a primary link fails.
Installation Requirements:
- Network Cabling: Use shielded Cat5e or Cat6 Ethernet cables with proper grounding to ensure EMC compliance.
- Redundancy Setup: When using MRP, configure the ring topology correctly in the engineering software to prevent broadcast storms.
- Addressing: Assign unique IP addresses and station names to prevent network conflicts.
- Environment: Install in a controlled environment avoiding direct sunlight, excessive vibration, or corrosive gases.
Usage Precautions:
- ESD Protection: Always use electrostatic discharge protection when handling the module to prevent damage to sensitive communication ICs.
- Firmware Compatibility: Ensure the module firmware is compatible with the AC800M controller’s operating system version.
- Cable Routing: Maintain strict separation between Ethernet cables and high-voltage power cables to prevent signal degradation.
- Diagnostics: Regularly monitor the LED indicators and software diagnostics to proactively identify network degradation.
