• Communicates with other DeviceNet devices (I/O
and messages)
• Requires explicit messaging
• Uses the controller as a master or slave on the
DeviceNet network
• Uses the controller serial port for other
communications
• Requires higher performance than available from
the 1769-NET-DNI interface
1769-SDN DeviceNet
scanner
The scanner acts as an interface between DeviceNet
devices and the CompactLogix controller. The scanner
lets the controller:
• read inputs from slave devices.
• write outputs to slave devices.
• send and receive messages.
• Communicates with other DeviceNet devices
(messaging only)
• Uses the controller only as a slave on the
DeviceNet network
• Does not use the controller serial port for other
communications
• Trades lower cost for lower performance than the
1769-SDN scanner
1761-NET-DNI interface
The interface module links the CompactLogix
controller to other devices on a DeviceNet network
to:
• download configuration data to a device.
• monitor operational status of a device.
• communicate with peer devices (messaging).
• upload/download programs.
• Accesses remote Compact I/O over a DeviceNet
network
• Sends remote I/O data for as many as 30 modules
back to scanner or controller
1769-ADN DeviceNet
adapter
The adapter:
• interfaces with as many as 30 Compact I/O
modules.
• communicates to other network system
components (typically a controller or scanner and/or
programming terminals).

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. The DeviceNet network is a flexible network that works with
devices from multiple vendors.
