DeviceNet Communication Module

The Allen-Bradley 25-COMM-D is a DeviceNet communication adapter designed for the PowerFlex 520 series of adjustable frequency AC drives, including the PowerFlex 525, 523, and 520 models. The adapter supports data rates of 125 Kbps, 250 Kbps, and 500 Kbps, and features a Multi-Drive feature that allows up to five drives to share a single DeviceNet address node, reducing network overhead and installation costs

The Allen‑Bradley 1769‑SDN is a Compact I/O DeviceNet Scanner Module designed for the CompactLogix and MicroLogix 1500 controller platforms. It acts as a scanner on the DeviceNet network, collecting I/O data from up to 63 slave devices via strobe, poll, change‑of‑state, or cyclic messages, and makes that data available to the controller for application logic

The Allen‑Bradley 1756‑DNB is a DeviceNet Bridge/Scanner Module for the ControlLogix® platform that interfaces between DeviceNet devices and the ControlLogix controller. It acts as a scanner on the DeviceNet network, collecting I/O data from up to 64 slave devices and mapping it into the controller's tag database.
