Communication Modules

DeviceNet Network

The DeviceNet network is an open, low-level network that provides connections between simple industrial devices (such as sensors and actuators) and higher-level devices (such as PLC controllers and computers). The DeviceNet network uses the proven Common Industrial Protocol (CIP) to provide the control, configure, and data collection capabilities for industrial devices.

Select a DeviceNet Interface

The 1769-ADN and 1769-SDN communication modules interface with all CompactLogix controllers.

If your application	Select
• Communicates with other DeviceNet devices (I/O and messages) • Requires explicit messaging • Uses the controller as a master or slave • Uses the controller serial port for other communication • Requires higher performance than the 1761-NET-DNI interface	1769-SDN DeviceNet scanner
• Uses any CompactLogix controller • Accesses as many as 30 remote Compact I/O modules • Sends remote I/O data back to a scanner or controller	1769-ADN DeviceNet adapter

Accessories—DeviceNet Network

Cat. No.	Description
KwikLink Lite flat media	KwikLink Lite flat media is a newer, ODVA-approved solution for wiring DeviceNet networks. Drop-lines for connecting nodes are added by using the KwikLink Lite two-piece connectors. This cable system supports the intermixing of DeviceNet cable types (thin-round with flat). All of the KwikLink Lite connectors provide insulation displacement technology with reduced assembly time.
KwikLink flat media	The KwikLink flat media system provides a modular cabling method with its flat 4-wire cable and Insulation Displacement Connectors (IDCs). The KwikLink system allows nodes to be added to the network without severing the trunkline. Cutting or stripping of the trunkline is eliminated, as is the need for predetermined cable lengths.
Round media	Round trunk cable is available in bulk spools or as pre-molded cordsets or patchcords in varying lengths. A wide variety of rugged, durable DeviceNet components is available for use in round trunk systems. Stainless steel versions of round cable system components are also available. • Thick trunk round media systems use thick cable for maximum DeviceNet trunk line length. • Round media thin trunk systems use thin cable to reduce maximum trunk line distances with a more compact and cost-effective installation for some applications. Thin cable outer jacket material is TPE for additional chemical resistance.
