ProSoft 1203-GD1 Module | Connect DeviceNet Devices to Allen-Bradley PLC Systems

Technical Specifications

Main Features and Advantages

Seamless Multi-Vendor Network Integration: The standout advantage of the ProSoft 1203-GD1​ is its ability to create transparent connectivity between two distinct industrial networking worlds. It allows an Allen-Bradley PLC using a standard 1771 or 1747 series scanner card to control and monitor a wide array of DeviceNet devices from any vendor (e.g., sensors, motor starters, valve manifolds, drives) as if they were native Allen-Bradley Remote I/O modules. This eliminates the need for a separate DeviceNet master card in the PLC chassis or a complete network migration. The 1203-GD1 module​ handles all the complex protocol translation in real-time, making the integration process straightforward and reducing engineering time significantly.Robust and Flexible Configuration: The ProSoft Technology 1203-GD1​ is designed for ease of use and reliable operation. Key parameters for the Remote I/O side, such as the rack address and communication rate, are set via simple DIP switches, allowing for quick field setup. The DeviceNet network configuration is performed using standard DeviceNet configuration tools (like RSNetWorx for DeviceNet), providing a familiar environment for network setup and device mapping. The module acts as a powerful DeviceNet scanner, supporting explicit messaging for device configuration and implicit (I/O) messaging for high-speed cyclic data exchange. This flexibility allows the 1203-GD1​ to handle a mix of simple I/O devices and more complex devices with parameter data. Its robust design includes optical isolation on all network ports, protecting the module and connected equipment from ground loops and electrical noise, ensuring stable data transmission in harsh plant environments.

Application Field

The ProSoft Technology 1203-GD1​ is invaluable in manufacturing and processing facilities that operate with a mix of Allen-Bradley control systems and DeviceNet-enabled field devices. A classic application is in Automotive Manufacturing plants, where legacy Allen-Bradley PLC-5 or ControlLogix systems control major production lines. The 1203-GD1 module​ enables the integration of newer, smart DeviceNet devices—such as photoelectric sensors on a conveyor, variable frequency drives on a paint booth fan, or distributed I/O blocks on a welding station—directly into the existing control architecture without costly PLC upgrades or rewiring. This allows for modernization and the addition of diagnostics at the device level while preserving the core control investment.In Material Handling and Packaging systems, the module is used to connect DeviceNet barcode scanners, sortation actuators, and motor starters to a central Allen-Bradley controller. The ProSoft 1203-GD1​ provides a clean, centralized data path, simplifying control logic and improving system diagnostics. Within Water/Wastewater Treatment facilities that have standardized on Allen-Bradley but utilize DeviceNet-enabled analyzers (e.g., for pH or chlorine) or valve actuators, the gateway serves as the perfect bridge. It is also extensively used in retrofit and upgrade projects across industries like Food & Beverage and Pharmaceuticals, where the goal is to incorporate newer, feature-rich DeviceNet devices into a stable, existing Allen-Bradley Remote I/O based control system. The 1203-GD1​ effectively future-proofs the control system by breaking down protocol barriers.
