Packaging OEMs are under constant pressure to build machines that are flexible, easy to integrate, and simple to support long after installation. In a recent episode of The Downtime Podcast, hosts Sarah Wynn and Sheri Kasprzak sat down with Weintek’s Automation Expert Nikki Gonzales to discuss how modern HMIs are evolving to meet these demands. Watch the podcast HERE.
During the conversation, Nikki explains how Weintek HMIs have become far more than operator screens. Instead, they function as a central hub that connects machines, systems, and people across the plant floor and beyond. For packaging OEMs in particular, this “universal remote” approach solves many of the interoperability and lifecycle challenges they face.
The Role of HMIs in Packaging OEM Machine Design
For many OEMs, the HMI has historically been treated as an afterthought. It displayed buttons, alarms, and basic status information, but rarely influenced broader system architecture. Nikki shared that this mindset is rapidly changing, especially in packaging environments where machines must operate across a wide range of customer facilities.
Packaging OEMs often have little control over what PLC brand, network protocol, or automation ecosystem their customer uses. A machine built for one plant may later be installed in a completely different environment. This is where an HMI designed for flexibility becomes critical. Weintek HMIs support hundreds of industrial communication protocols, allowing OEMs to design once and deploy everywhere without locking customers into a single vendor ecosystem.
HMIs as a Universal Remote for Industrial Systems
One of the most compelling ideas discussed in the podcast is the comparison of a modern HMI to a universal remote. Instead of controlling a single device, the HMI acts as a gateway that allows multiple systems to communicate seamlessly.
Weintek HMIs can bridge protocols between devices on the machine, eliminating the need for multiple standalone gateways inside the control cabinet. OEMs can translate data between EtherNet/IP, Modbus, EtherCAT, PROFINET, and other protocols directly through the HMI. This reduces hardware costs, simplifies cabinet design, and makes long-term maintenance easier.
Beyond machine-level communication, Weintek HMIs also support IIoT functionality such as OPC UA, MQTT, and secure remote access. This allows OEMs and end users to move data upstream to SCADA, MES, or cloud platforms without adding complexity.
Simplifying Training and Long-Term Support
Another key theme from the podcast is training and usability. Packaging lines experience frequent operator turnover, machine upgrades, and retrofits. Nikki emphasized that consistency in the HMI experience plays a major role in reducing training time and operational risk.
Weintek provides a clear upgrade path from legacy HMIs to modern capacitive touchscreen models, allowing OEMs and end users to reuse and migrate existing projects. EasyBuilder Pro, Weintek’s free HMI software, is designed to be approachable for beginners while still offering advanced functionality for experienced engineers.
Instead of relying on expensive, gated training programs, Weintek offers extensive free resources including hundreds of video tutorials and direct access to support engineers. This empowers OEMs and end users to learn at their own pace and resolve issues quickly, even outside of standard support hours.
Why Packaging OEMs Benefit from an OEM-First Approach
Weintek’s long-standing focus on OEMs also resonated throughout the conversation. Unlike vendors that attempt to sell complete automation ecosystems, Weintek concentrates exclusively on HMIs and related connectivity solutions. This specialization allows OEMs to integrate Weintek products into virtually any machine design without forcing downstream customers to adopt new standards.
Nikki highlighted that Weintek maintains transparent, OEM-friendly pricing with no hidden licensing fees or recurring subscriptions. This is especially important in packaging, where cost control and predictable machine pricing are essential to staying competitive.
The Future of HMIs in Packaging Automation
As packaging operations continue to modernize, HMIs will play an even larger role in connecting machines, people, and data. The podcast makes it clear that the HMI is no longer just an interface. It is a communication hub, a training tool, and a bridge between legacy equipment and modern automation strategies.
For packaging OEMs looking to build machines that are easier to integrate, easier to support, and ready for the future, treating the HMI as a “universal remote” is a powerful shift in mindset.
Key Takeaways:
- Supporting multiple protocols is essential for meeting strict application needs.
- The protocol chosen should always reflect the structure, processing speed, and feature requirements of the application.
