Description
    • Environmental and Indicator Parameters
      • The operating temperature range is 0°C to 60°C, and the storage temperature range is -40°C to 85°C, adapting to most industrial working environments.
      • It can operate normally in environments with 5% to 95% relative humidity, non-condensing. The module is equipped with LED indicators for power, module status, PROFIBUS DP communication status and fault status, enabling intuitive monitoring of the module’s operating conditions.
    • Software and Compatibility Parameters
      • Configuration is completed via ProSoft Configuration Builder (PCB) software, which supports offline configuration and online parameter modification without stopping the system.
      • It is fully compatible with Rockwell RSLogix 5000 software, and the data exchange between the module and the ControlLogix processor is realized through block transfer (BT) instructions or the side-connect interface.
  • Functional Features
    • Dual Standard Compliance for Wide Compatibility
      • Compliance with PROFIBUS DP V0 and V1 standards allows the module to communicate with various PROFIBUS DP master devices, including Siemens S7-300/400/1200/1500 PLCs and other brand PROFIBUS DP masters. The support for acyclic services enables advanced functions such as remote parameterization and diagnostic data reading.
      • The configurable slave address and baud rate make the module adaptable to different PROFIBUS DP network architectures, eliminating compatibility barriers between Rockwell ControlLogix systems and PROFIBUS DP devices.
    • Flexible Data Exchange Mechanism
      • The 244-byte input and output data areas meet the data transmission needs of most industrial control scenarios. The asynchronous data transfer method separates the ControlLogix processor’s operation from the PROFIBUS DP network’s data transmission, avoiding mutual interference and ensuring the stability of both the control system and the communication network.
      • Support for both cyclic and acyclic communication modes enables the module to handle real-time control data (cyclic) and non-real-time diagnostic/configuration data (acyclic) separately, optimizing data transmission efficiency and network bandwidth utilization.
    • Easy Configuration and Maintenance
      • The ProSoft Configuration Builder software provides a graphical user interface for parameter setting, including slave address, baud rate, data area mapping and acyclic service configuration. The software also supports configuration file import and export, facilitating batch configuration of multiple modules.
      • The LED indicator panel and detailed diagnostic data accessible via RSLogix 5000 software enable maintenance personnel to quickly locate faults such as communication interruptions, parameter mismatches and power supply abnormalities, reducing system downtime.
    • Reliable Integration with ControlLogix Systems
      • The single-slot design and compatibility with local/remote racks maximize the flexibility of system layout, especially suitable for distributed control systems where the PROFIBUS DP network is far from the ControlLogix main chassis.
      • The seamless integration with RSLogix 5000 software allows the module’s data to be directly mapped to ControlLogix controller tags, simplifying programming and data access for engineers.
  • Application Scenarios
    • Automotive Manufacturing Industry
      • In automobile assembly lines, the module connects ControlLogix systems with PROFIBUS DP-equipped robotic arms, welding equipment and conveyor systems. It transmits real-time control commands from the ControlLogix processor to the on-site equipment and collects equipment operation status data, ensuring the coordination and efficiency of the assembly line.
    • Petrochemical Industry
      • In petrochemical plants with mixed Rockwell and Siemens control systems, the module acts as a communication bridge between ControlLogix processors and PROFIBUS DP-based flow meters, pressure transmitters and valve positioners. It realizes the unified monitoring and control of key process parameters, supporting safe and stable operation of the production process.
    • Food and Beverage Industry
      • In automated food packaging lines, the module links ControlLogix controllers with PROFIBUS DP-compatible weighing machines, labeling equipment and temperature control devices. It ensures accurate data transmission between the central control system and on-site equipment, maintaining consistent product quality and production efficiency.
    • Metallurgical Industry
      • In steelmaking and rolling workshops, the module connects ControlLogix systems with PROFIBUS DP-based temperature sensors, thickness gauges and motor drives. It transmits real-time data of smelting temperature and steel plate thickness to the controller, and the controller adjusts process parameters in a timely manner to meet the quality requirements of metallurgical products.
    • Legacy System Upgrade Projects
      • When upgrading legacy production lines equipped with PROFIBUS DP devices to Rockwell ControlLogix systems, the module enables seamless connection between the new control system and existing field devices. It avoids the need to replace a large number of PROFIBUS DP devices, reducing upgrade costs and minimizing production downtime.
