Studio 5000 Ethernet Connection Status Using a GSV Instruction

Studio 5000, a comprehensive software suite developed by Rockwell Automation, plays a pivotal role in programming and configuring industrial control systems. Within this suite, the management of Ethernet connections is crucial for facilitating communication among devices in industrial settings. This article delves into the Studio 5000 Ethernet Connection Status using the Get System Variable (GSV) instruction, a valuable tool for monitoring and troubleshooting network connections.

The GSV Instruction:

The Get System Variable (GSV) instruction is a versatile command within Studio 5000, allowing users to retrieve information about the controller’s operating environment. This encompasses data related to system parameters, communication status, and other runtime details. For Ethernet connection monitoring, the GSV instruction proves to be particularly useful.

Understanding Ethernet Connection Status:

Before exploring the GSV instruction, it’s essential to grasp the significance of Ethernet connection status in an industrial automation context. Industrial control systems heavily rely on Ethernet communication to exchange data between programmable logic controllers (PLCs), human-machine interfaces (HMIs), and other devices. Monitoring the status of these connections is vital for ensuring the reliability and performance of the overall system.

Using GSV for Ethernet Connection Status: To obtain Ethernet connection status using the GSV instruction, users must locate the specific system variable addressing Ethernet status. Typically found in the [Controller] > [Controller Tags] > [System] > [ENet] > [ENetModule] > [Status] path, the Ethernet status system variable can then be accessed using the GSV instruction.

Benefits of Using GSV for Ethernet Monitoring:

  1. Real-time Monitoring: GSV facilitates real-time monitoring of Ethernet connection status, allowing for the swift identification of issues or disruptions.
  2. Diagnostic Capabilities: Incorporating GSV instructions into Studio 5000 programs enhances diagnostic capabilities, enabling proactive maintenance and troubleshooting.
  3. Improved System Reliability: Monitoring Ethernet connection status contributes to the reliability of communication within the industrial control system, minimizing downtime and improving overall operational efficiency.


Effective management of Ethernet connections is paramount in industrial automation, and Studio 5000 provides a robust solution through GSV instruction. By integrating GSV into programming logic, users can monitor Ethernet connection status, enabling timely responses to potential issues and contributing to the seamless operation of industrial control systems.

Video – Studio 5000 Ethernet Connection Status

The video below shows an example of using a GSV instruction to monitor the connection status.

This is a short video to give a clear and easy understanding of using a GSV to monitor the connection status of a device in your I/O rack.

This video uses Studio 5000 version 35.

I will be putting together more programming videos and articles upon request, I already have several ideas and will be starting to add more videos to my YouTube channel which is Shane Welcher

I would love to hear what you guys think so far as I try to get this website whipped into shape.

Drop me a comment here or on my YouTube channel.
