Functional Features:
- Manages real-time data exchange and node routing (NCU variant)
- Buffers data and manages handshake with CPU
- Handles digital field device interfacing (SIO variant)
- LED indicators for channel status and module health
Installation Requirements:
- Power down rack unless hot-swap is explicitly supported
- Discharge static electricity before handling
- Use extraction levers or pull gently by faceplate edges
- Align carefully with guide rails before insertion
Usage Notes:
- Verify hardware revision compatibility (Ver. 05, 07, 08, 09)
- Clear or reconfigure network parameters/IP addresses before installation
- Inspect card guide rails for debris to prevent misalignment
- Do not mix incompatible revisions in the same rack
