The 1761-NET-DNI (DeviceNet Interface) from Rockwell Automation is a communication gateway module used to connect MicroLogix, SLC, and other DF1-based devices to a DeviceNet industrial network.
It acts as a protocol converter between DF1 serial communication and DeviceNet, enabling older PLC systems to participate in DeviceNet-based distributed control architectures.
Typical use cases include:
- Connecting MicroLogix PLCs to DeviceNet networks
- Peer-to-peer communication between controllers
- DeviceNet master/slave integration
- Legacy system network expansion
Main Functions
The 1761-NET-DNI provides:
- DF1 ↔ DeviceNet protocol conversion
- DeviceNet slave operation (with peer-to-peer messaging capability)
- Serial RS-232 communication interface for PLC connection
- Multi-node DeviceNet network participation
- Data exchange between PLCs and DeviceNet master controllers
It allows legacy MicroLogix or SLC controllers to communicate on a modern (for its era) industrial fieldbus network.
