Product Features
Allen Bradley 1734-ADN functions as a slave device in the DeviceNet master network, supporting communication with the master device via Polled, Strobe, Change of State, and Cyclic modes.
Allen Bradley 1734-ADN operates as a master device in the PointBus backplane, managing up to 63 POINT I/O modules (up to 62 if ADR functionality is enabled), responsible for data acquisition and command issuance.
Allen Bradley 1734-ADN does not require manual configuration of EDS parameters, automatically detects backplane modules, assigns addresses, generates scan lists, and maps I/O data (supporting byte, word, double word, or fixed-boundary mapping), enabling rapid system startup.
After enabling it via RSNetWorx for DeviceNet software, Allen Bradley 1734-ADN can sequentially assign addresses to backplane I/O modules (starting from the module closest to the adapter and incrementing).
Allen Bradley 1734-ADN supports automatic configuration of replacement modules (provided the replacement module matches the original module's electronic key) and automatically downloads the original module's configuration parameters.
Allen Bradley 1734-ADN supports DeviceNet network Autobaud (automatic baud rate detection), compatible with 125K, 250K, and 500K baud rates, the default baud rate for the PointBus backplane is 1Mbaud.
Allen Bradley 1734-ADN can achieve data caching and forwarding through an internal memory buffer, supporting independent mapping of input data (3 buffers) and output data (1 buffer).
Upon power-up, Allen Bradley 1734-ADN automatically detects internal memory, status indicators, to ensure hardware functionality.
Allen Bradley 1734-ADN maintains the Faulted Node Table, Idle Node Table, and Node Status Table, and module fault causes can be viewed via RSNetWorx software.
Allen Bradley 1734-ADN supports upgrading Boot and Application code via the ControlFlash tool to maintain functional updates.
Product Working Principle
The DeviceNet master device sends output data to the 1734-ADN via I/O messages, which is stored in the internal output buffer.
The 1734-ADN, acting as a PointBus master device, forwards the output data to the corresponding I/O module.
The I/O module sends the collected input data to the 1734-ADN, which is stored in the internal input buffer.
The 1734-ADN feeds back the input data to the master device via the DeviceNet network, completing a data loop.
It can quickly generate scan lists and data mappings using Auto Start Mode, suitable for default configuration scenarios.
It supports offline or online configuration of parameters such as baud rate, address, scan list, and electronic key using RSNetWorx for DeviceNet software, and supports custom data mapping rules.
