TECHNICAL SPECIFICATIONS
The Allen-Bradley 1756-DNB/A DeviceNet scanner module serves as a connection bridge, collecting data from DeviceNet modules and sending copies to the controller and back.
The user can anticipate DeviceNet connection speeds of up to 500 KB per second when using the 1756-DNB/A scanner module, with a default speed of 125 KB per second. DeviceNet node addresses for the module range from 0 to 63, with 63 being the default, and it can support up to 64 nodes.
The Logix5550 controller is the only one with which it works. The module may download configuration information, read and write to from devices, and keep track of their operational status since it serves as a bridge between DeviceNet-using devices and the network itself.
The Allen-Bradley 1756-DNB/A scanner module interfaces with the controller through diagnostic tables, inputs, and outputs. The module uses cyclic, poll, strobe, and change-of-state signals to connect with other devices. All devices get or receive data from these messages. The controller gets structured data (input data) from the device immediately after it transmits it, and the controller then transmits that data back to the device (output data).
Regarding current consumption, the 1756-DNB/A scanner module utilizes 400 mA at 5.1V dc and 0 mA at 24V dc. This module's thermal dissipation is 11.9 BTU/h, while its power dissipation is around 3.5 Watts/h. This module functions with the RSNetWorx and may be inserted in any open chassis slot.
The open-type DeviceNet network used by the 1756-DNB/A ControlLogix DeviceNet scanner module makes it possible to link basic devices used for specialized processes in an industrial setting. These include enhanced gadgets and important devices, including computers, controllers, sensors, and actuators.
The Common Industrial Protocol (CIP) is a key component of the DeviceNet network's operation since it allows for configuring industrial devices and controlling systems. This module has a voltage rating of 11 to 25V dc and can support up to 64 nodes.
A basic form of insulation and DeviceNet network to backplane characteristics are included, and the isolation voltage is 50V (continuous).
Various chassis types and standard/redundant power supply configurations are compatible with the ControlLogix 1756-DNB/A scanner module. DeviceNet power meets UL requirements and the CE low voltage LVD guideline. Users must adhere to certain regulations about the different types of power supplies to meet these standards.
This module contains one linear open-style connector with 5 or 10 pins for DeviceNet connections. Data is sent at a maximum speed of 12 Mbps and USB 2.0. The module's working temperature should be between 0 and 60 °C (32 and 140 °F). Storage is allowed in the -40 °C to 85 °C (-40 °F to 185 °F) temperature range.
