Responsiveness, cost-efficiency, and safety are the key pillars of a successful and productive partnership between an original equipment manufacturer (OEM), an integrator, or an end user. However, physically accessing logic controllers can be challenging—or even impossible—in certain situations, such as remote installations, hard-to-reach areas, or environments with strict safety requirements. These constraints slow down interventions and increase downtime, directly impacting productivity.
To address these challenges, new solutions are emerging to simplify operations. Among them, remote access to the controller screen known as virtual display allows teams to monitor, diagnose, and interact with their equipment in real time, without the need to travel on site. An approach that is fundamentally transforming industrial maintenance.
The challenges of traditional industrial maintenance
Imagine… You are a machine manufacturer or integrator, and your customer asks for a solution to improve machine management and control while minimizing downtime. This seemingly simple upgrade requires updating and installing software, which in turn means sending a technician on site.
The need to be on site
Despite advances in automation, industrial maintenance still largely relies on physical interventions. This approach presents several limitations that hinder team responsiveness and efficiency.
First, accessing machines can be complex. Some installations are in hard-to-reach areas, remote sites, or environments with strict safety constraints. This often involves lengthy procedures—or even production shutdowns—just to reach the controller.
In addition, intervention times can be significant. When an issue occurs, diagnosing and resolving it may take longer, especially if a technician must travel on site. These delays lead to productivity losses and increase costs associated with unplanned downtime.
Mobilize local experts
Moreover, maintenance often requires qualified personnel to be physically present. However, mobilizing experts is not always easy, particularly for remote sites or installations spread across multiple locations. This can slow decision-making and complicate resource management.
Finally, diagnostics carried out under time pressure or constrained conditions increase the risk of errors. Limited system visibility or misinterpretation of displayed information can lead to inappropriate intervention or even worsen the situation.
Faced with these limitations, it becomes essential to rethink maintenance methods. In this context, remote access solutions such as virtual display are emerging as a more agile and efficient alternative.
What is a virtual display for industrial controllers
Virtual display allows the interface of a logic controller to be replicated on a computer or tablet, without requiring physical access to the equipment. This technology provides real-time visibility and full interaction with the controller.
Concretely, it enables users to:
- View the controller screen remotely in real time
- Access key data (parameters, statuses, alarms)
- Interact with the buttons as if they were on site
- Adjust settings and perform diagnostics remotely
Easy to integrate into connected industrial environments, the remote screen is becoming an essential tool for modernizing maintenance and improving team responsiveness.
Key benefits of virtual display
- Faster Troubleshooting
Remote access to the controller screen enables instant troubleshooting, without waiting for a technician to be physically on site. Teams can analyze the situation in real time, quickly identify the root cause of an issue, and take immediate action. The result: significantly reduced downtime and improved production continuity.
- Improved Efficiency
Thanks to the virtual display experts can intervene remotely regardless of the installation’s location. This facilitates collaboration between teams and enables the right expertise to be mobilized quickly, without geographical constraints. Field teams also save time by avoiding unnecessary travel and accessing the information they need more quickly.
- Enhanced Safety
Some interventions require access to potentially hazardous or hard-to-reach areas. By leveraging a virtual display, you can limit these situations by performing maintenance operations without being physically present at the machine. This reduces risk exposure and improves operators’ working conditions.
- Cost Reduction
By reducing travel and optimizing interventions, remote access directly contributes to lowering maintenance costs. Less time wasted, fewer resources required, and better anticipation of issues all help improve overall operational performance.
How virtual display simplifies programming and monitoring
Virtual Display is transforming the way teams program and monitor their installations. By providing direct, real-time access to the controller interface, it enables fast intervention without physical constraints.
Thanks to this technology, it becomes possible to:
- Access the controller interface at any time, as if you were on site
- Modify parameters remotely in just a few clicks
- Perform tests and adjustments instantly
- Continuously monitor system operations
This approach significantly simplifies programming tasks. Automation engineers can work more efficiently, without interruption, while maintaining full visibility over the system.
At the same time, the remote screen ensures better operational continuity. Adjustments can be made in real time, reducing production downtime and enabling optimal responsiveness to unexpected events.
Easy to use and quick to deploy, it stands out as a key tool for improving agility and performance in modern industrial environments.
Discover Crouzet virtual display
With the constant desire to make operations easier, Crouzet has taken things one step further in the design and manufacture of communication systems by introducing its new app, the Crouzet Virtual Display, and providing a win-win relationship opportunity.
Simple and mobile for greater responsiveness
Crouzet is now offering you an alternative with a free app that will save you a lot of time and money. To provide your customer with fast support, all you have to do now is send the updated program, by email for example, to an on-site contact who can then simply transfer it from his phone via Bluetooth.
With the Crouzet Virtual Display, instead of sending technicians to work on site, machine manufacturers, panel manufacturers and other users now have a new solution to help implement their maintenance operations.
Virtual Display but real benefits
Designed to allow remote access to the controller’s display and front-end buttons, it provides an accurate representation of the display of the connected PLC without any need for additional coding on this virtual display. In addition, the Crouzet Virtual Display can be used on both PCs and mobile devices and can communicate with the controller via Ethernet, Bluetooth or a USB port.
This flexibility improves mobility and facilitates remote operations: making them easier than ever, from anywhere, without (un)plugging a single cable.
Virtually connected to an em4 or Millenium EVO (nano-plc, remote controller or Crouzet logic controller), the tool offers clear advantages for monitoring, daily supervision and maintenance of the systems. Its features allow you to view and change settings, read and write programs or applications, download datalog, or perform a diagnostic analysis.
This means you are able to choose the best location for the controller in the overall installation. By connecting a smartphone to several “blind” products, it is no longer necessary to actually see them in front of you and the result is a very economical solution. Moreover, there is also a guarantee of employee safety. The procedure is fast and safe even in remote locations, where access is difficult or where the computer network is inadequate.
Conclusion
As industrial environments become increasingly complex and connected, maintenance methods must evolve to remain efficient and responsive. Remote access to controller screens, or virtual display, is now emerging as a concrete solution to the challenges of productivity, safety, and cost reduction.
By enabling real-time visualization, diagnostics, and interaction with equipment, this approach greatly simplifies maintenance and programming operations. It provides teams with greater flexibility while reducing the constraints associated with on-site interventions.
With solutions like Crouzet Virtual Display, manufacturers gain access to a simple yet powerful tool to take a step forward in the digitalization of their processes—an opportunity to improve efficiency while ensuring optimal operational continuity.
