Allen Bradley 1769-ADN CompactLogix DeviceNet Adapter I-O Module
The Allen-Bradley 1769-ADN is a CompactLogix I/O DeviceNet Adapter module. It is an open, low-level network module that connects simple industrial devices such as actuators and sensors with high-level devices such as computers and PLC controllers. It uses the well-known Common Industrial Protocol (CIP) that provides various capabilities such as control, data collection, and configuration for industrial devices. It connects low-level devices directly to plant floor controllers instead of interfacing them through I/O modules. Data is sent as needed through
