About 1756-DNB:
The Allen-Bradley 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. Using the 1756-DNB scanner module, the user can expect DeviceNet communication rates of 125 kilobytes per second by default, 250 kilobytes per second, and up to 500 kilobytes per second. It has DeviceNet node addresses 00 to 63, with node address 63 set by default and a maximum of 64 nodes. It is only compatible with the Logix5550 controller. This particular module acts as a gateway between DeviceNet devices and the network in order to read input and write output from a device, download the configuration data, and monitor the operational status of a device.
