The 1756-DNB will communicate in the form of Diagnostic Tables, Inputs, and Outputs when the controller is involved. The I/O’s exchange configuration data, status information, and the I/O data of the device. The module communicates using strobe, poll, change of state, and/or cyclic messages with another device. These messages are used to gather from or deliver data to every device. The data received from a device will then be organized and made available to the controller (input data) and the data received from the controller will be sent to the device (output data). 

The 1756-DNB's current draw at 5.1 Volts DC is 400 milliamps while it stays at 0 milliamps when the current draw is at 24 Volts DC. The power dissipation of this module is around 3.5 Watts and its thermal dissipation is at 11.9 BTU/hour. This module can be installed in any available chassis slot and is used together with the RSNetWorx.

The 1756-DNB is a DeviceNet Scanner module that connects to a ControlLogix system. It serves as a bridge that collects data from the DeviceNet modules and then delivers a copy of the information to the controller and vice versa.
