Features:
- Provides the Cnet network-interface front end.
- Works with the SPNPM22 network processor.
- Supports documented Cnet rates of 10 MHz or 2 MHz.
SPNIS21 is the ABB front-end network interface for a Cnet communication node.
It links the node to Cnet so modules can communicate with other network nodes and operates with SPNPM22.
For SPNIS21, confirm the exact companion hardware, network mode, addresses, firmware and termination before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Cnet links operate at the documented 10 MHz or 2 MHz rate and connect control nodes across the Symphony network.
- The interface routes node traffic onto Cnet while the paired processor manages communication with the rack bus.
- Node addressing, network cabling and termination must follow the installed topology before the communication interface is energized.
- Operation requires the documented SPNPM22 network processor and the correct rack positions for the communication pair.
- ABB communication kits combine matched interface modules, processors, cables and termination hardware for defined Cnet architectures.
- Verify node type, companion revision and system release because physical fit alone does not establish functional compatibility.
- The Cnet connection carries peer traffic between Harmony control nodes and supported supervisory computer interfaces.
- The rack-side path exchanges communication data through Controlway and the paired network processing module.
- Cable routing, shielding and termination values must conform to the control-network installation documentation.
