          PRODUCT DESCRIPTION

          1756-DNB DeviceNet Scanner Communication Module

          1756-DNB is a DeviceNet Scanner Communication Module in the ControlLogix family. It connects a ControlLogix controller to devices on a DeviceNet network through a configured scan list.

          The scanner mounts in a ControlLogix chassis and exchanges network I/O with the controller through the backplane. DeviceNet communication speed and trunk length must be coordinated, and status indicators support network diagnostics. USB servicing applies to the documented Series C/D configuration; confirm the actual supplied series.
