  • Rockwell Automation’s RSLinx is a communication and connectivity software.
  • Its major function is to establish communication between devices in an industrial automation system.
  • RSLinx serves as a communication bridge, allowing data to be exchanged and controlled between various devices and software applications.
  • Device discovery is a core function of RSLinx.
  • It helps in the identification and configuration of network-connected automation devices.
  • When you have a complicated automation system with several PLCs, HMIs, and other devices, RSLinx simplifies the process of identifying and configuring these components.
  • RSLinx also supports data access, allowing engineers and operators to read and write data to and from PLCs and other devices.
  • This data access is critical for monitoring processes, making real-time modifications, and gathering useful data for analysis and optimisation.
  • RSLinx can also serve as an OPC (OLE for Process Control) server. OPC is a popular industry standard for linking industrial automation software and hardware components.
  • RSLinx serving as an OPC server allows third-party programmes to access data from linked devices, such as data historians or custom software solutions.

In summary, RSLinx is primarily in charge of:

  • Device detection and configuration.
  • Offering communication drivers for a variety of devices.
  • Providing data access to PLCs and other devices.
  • Serving as an OPC server for the integration of third-party software.

  • RSLogix, on the other hand, is a collection of software tools used to programme and configure programmable logic controllers (PLCs) in industrial automation systems.
  • The RSLogix suite includes software packages such as RSLogix 5000, RSLogix 500, and RSLogix Micro, which are each geared to various Rockwell Automation PLC systems.
  • RSLogix’s primary function is PLC programming. RSLogix is used by engineers and programmers to construct the control logic that governs industrial processes.
  • It is compatible with a variety of programming languages, including ladder logic, structured text, function block diagrams, and sequential function charts.

This flexibility enables users to select the best language for their application.

  • In addition, RSLogix provides PLC configuration tools. Users can modify the connected PLC’s hardware settings, I/O modules, and connection parameters.
  • This phase is critical to ensuring that the PLC interacts correctly with other devices and achieves its control objectives.
  • RSLogix also includes simulation capabilities, which allow users to test and debug PLC logic without interfering with the actual industrial process.
  • This tool is essential for debugging and fine-tuning control programmes to ensure they work as intended.

In summary, RSLogix is primarily in charge of:

  • PLC programming in a variety of languages.
  • Configuration of the PLC, including hardware and communication settings.
  • Control logic simulation for testing and debugging.

RSLinx and RSLogix work together in many industrial automation applications. RSLinx communicates with PLCs and other devices to ensure that data flows smoothly between them. Based on the connectivity created by RSLinx, RSLogix is used to programme and configure the PLCs. They work together to provide effective and dependable automation processes by designing, implementing, and maintaining industrial control systems.
