In production and administrative environments, multiple systems are often used in parallel, for example for order management, production control, or process monitoring. The need for information directly at the workplace is constantly increasing. In many cases, a single screen is no longer sufficient to display applications clearly. Whether a multi-monitor solution can be implemented depends largely on the respective IT and security guidelines. In particular, the question of whether different IP networks may be combined on a single end device determines the technical design. Against this background, R. Stahl offers two different solutions.

Multi-monitor operation with approved network coupling

If the company allows two networks to be connected within a single device, a multi-monitor architecture with a direct monitor is used. This is designed for potentially explosive areas in zones 1, 2, 21, and 22 and is connected to a thin client via USB.

The solution enables different applications to be displayed on separate monitors. Users can thus work with two screens, similar to an office workstation, but under industrial and explosion-proof conditions. Processes can be monitored and operated in parallel without having to switch between applications.

Shared keyboard as an alternative to multi-monitor

If network coupling is not permitted for safety reasons, R. Stahl offers a shared keyboard variant. In this case, two separate thin clients are used, on which the respective applications run strictly separated from each other. There is no direct connection between the networks.

Solution independent of automation or management systems

However, the keyboard and mouse are shared. The operator can switch between the systems, with the focus automatically placed on the active application. The solution works independently of specific automation or management systems and can be used universally. Horst Friedrich, Director of Product Marketing at R. Stahl HMI, explains: “Multi-screen and keyboard sharing enables companies to control their processes more efficiently whilst meeting all pertinent IT guidelines. This solution has been operated successfully for several months now in real-life applications.”

Multi-monitor technology for greater process reliability

The parallel display of multiple applications reduces sources of error and makes processes more transparent. Complex processes can be operated and documented simultaneously without the need for additional hardware or extensive network adjustments. The multi-monitor and shared keyboard concepts thus help companies improve their process control and comply with existing IT security requirements.
