Weidmuller Advances Open Control Systems for Enhanced Manufacturing Flexibility

At the Automate 2025 event, Weidmuller showcased its innovative approach to open control systems, illustrating how app-based ecosystems and adherence to industry-standard protocols are transforming the manufacturing landscape. This shift towards flexible and vendor-agnostic control technologies is seen as a pivotal development in industrial automation, enabling manufacturers to increase efficiency and reduce dependency on single-source vendors.

The demonstration, led by Ken Crawford, Weidmuller’s Senior Director of Automation, highlighted the growing reliability and security of open systems, which have gained increasing traction within the manufacturing sector. "Open control systems provide a platform that allows the installation of publicly available applications to build custom control solutions that meet specific requirements," Crawford explained. This approach minimizes the need for extensive design teams, as manufacturers can leverage proven applications to develop their software rapidly.

Weidmuller’s commitment to open control systems is underscored by its use of widely accepted industrial protocols such as OPC UA, MQTT, and Modbus. These protocols are supported by robust developer communities, facilitating a broader adoption of open technologies. "The proprietary systems, in contrast, rely on a closed architecture that discourages the integration of external software," Crawford noted, pointing out that these systems often necessitate ongoing investment to sustain their internal design capabilities.

In a separate discussion, Jack Fillenwarth, Senior Software Specialist at Weidmuller USA, elaborated on the company’s u-OS open control platform. During the event, he demonstrated how containerized applications operate on Weidmuller’s u-Control M4000 controllers, emphasizing the distinctiveness of their app-based ecosystem. "With u-OS, we can run multiple applications simultaneously on the same device, which streamlines operations and enhances accessibility through a web browser interface," Fillenwarth said.

Weidmuller’s open control systems stand in stark contrast to traditional automation setups, which typically rely solely on PLC runtime. The integration of remote I/O, u-link remote access, and ProCon-Web within the u-OS framework allows for comprehensive analysis and control of production flows, significantly enhancing operational efficiency.

The growing adoption of open control systems marks a significant trend in the manufacturing industry, where flexibility and adaptability are increasingly crucial. As companies continue to navigate the complexities of industrial automation, the support from established players like Weidmuller is critical in addressing the hesitations surrounding open systems. By providing scalable, secure, and customizable solutions, Weidmuller is positioning itself as a leader in the evolution of manufacturing technologies.

The implications of this shift extend beyond operational efficiencies; they pave the way for future innovations in industrial automation, potentially reshaping the competitive landscape. As manufacturers increasingly embrace open control systems, the industry may witness a reduction in costs and an increase in collaboration among vendors, ultimately benefiting end-users and consumers alike.
