A German printing firm, Senner Druckhaus GmbH, has successfully completed a major overhaul of its press control systems, transitioning from an older, proprietary platform too a modern, standardized system based on Beckhoff technology, known as DCOS. The upgrade was executed while maintaining uninterrupted nightly printing operations,a testament to the careful,phased migration strategy employed. The core of this transformation centers around improved data access and operational autonomy.
From Legacy Systems to Modern Control
For Years, Senner Druckhaus relied on a combination of PECOM, a Manroland control system, and a now-outdated S5 system. Recognizing the limitations of these legacy technologies, the company initiated a move towards a more flexible and accessible solution. The DCOS implementation wasn’t an overnight switch; rather, it involved running all three systems concurrently—PECOM, DCOS, and a coordinating system—requiring three dedicated printers per shift to manage the transition.
Empowering Operators Through Autonomy and Data
The redesigned system’s most striking benefit is increased operational autonomy.DCOS utilizes standard hardware components, empowering Senner Druckhaus’s technicians to handle repairs and replacements independently. This eliminates reliance on external service calls and reduces downtime. Furthermore, software updates and adjustments are now conducted remotely, streamlining maintenance and support.
“We can now solve hardware issues in-house,” stated a company spokesperson. “A huge gain is the idea of putting the intelligence into the software and not into the hardware.”
Previously, critical control logic resided within dedicated hardware cards, limiting availability and adaptability. With DCOS,that intelligence is embedded in the software,allowing for faster adaptation and troubleshooting.
Unlocking the Power of Press Data
The retrofit has ushered in an era of unprecedented data availability. Every aspect of the printing process—speed, splices, cutoff, ink levels, dampening settings, register motor performance, and more—is now meticulously recorded. Senner Druckhaus developed a custom “production recorder” tool that grants management, staff, and even clients the ability to review past production runs and analyze performance metrics.
This level of data clarity has fundamentally altered the company’s approach to problem-solving. According to sources within Senner Druckhaus, the focus has shifted from assigning blame to collaboratively identifying and implementing solutions. All personnel now have access to this valuable data, fostering a culture of proactive maintenance and continuous enhancement.
Cost Savings and Extended Asset Life
The move to a standardized system has also delivered significant cost benefits. Senner Druckhaus no longer requires a formal service agreement with DCOS, relying instead on on-demand phone support, primarily for software-related issues. The use of readily available, standard hardware ensures parts are consistently in stock or easily ordered, minimizing delays and expenses. According to a recent report by Smithers Pira, proactive maintenance driven by data analytics can extend the lifespan of printing equipment by up to 20%.
| Feature | Old System (PECOM/S5) | New System (DCOS) |
|---|---|---|
| Hardware | Proprietary, Limited availability | Standard, Readily Available |
| Maintenance | External Service Required | In-House Capabilities |
| Software Updates | on-Site Visits | Remote Access |
| Data access | Limited | Complete, Real-Time |
| Problem Solving | Blame-Focused | Solution-Oriented |
Ultimately, the DCOS retrofit has not onyl extended the operational life of Senner Druckhaus’s presses but has also transformed its internal processes and decision-making. “This project enabled us on many levels. Above all, it enabled us to deliver better products,” a company representative emphasized.

What are the main benefits of retrofitting a historic press with automation and data integration?
Retrofit Revolution: Extending a Historic Press Through Automation and Data
For decades, mechanical presses have been the workhorses of manufacturing, reliably forming metal components across countless industries. But as demands for efficiency,precision,and data-driven insights increase,simply replacing thes legacy assets isn’t always the most practical – or economical – solution.A growing trend, the “retrofit revolution,” focuses on extending the life and capabilities of historic presses through strategic automation and data integration. This article explores how to breathe new life into your existing press, unlocking performance gains and future-proofing your operations.
assessing Your Press for Retrofit Potential
Before diving into upgrades, a thorough assessment is crucial. This isn’t just about mechanical condition; it’s about evaluating the press’s suitability for modern automation technologies. Key areas to examine include:
* Mechanical Integrity: A detailed inspection of the frame, gears, crankshaft, and ram is paramount. Addressing wear and tear before adding automation prevents cascading failures.
* Control System Compatibility: Older presses often rely on relay logic or basic PLC systems. Determine the feasibility of integrating a modern, more powerful controller.
* Physical Space & Infrastructure: Consider the available space around the press for new sensors, safety systems, and potentially robotic integration. Electrical capacity is also a critical factor.
* Production Requirements: What are your current and projected production volumes, cycle times, and quality standards? This will dictate the scope and complexity of the retrofit.
Core Automation Upgrades: What to Prioritize
Several key automation upgrades consistently deliver significant ROI when retrofitting a historic press.
- PLC Migration & Modernization: Replacing outdated control systems with a modern Programmable Logic Controller (PLC) is frequently enough the foundation of a successful retrofit. This unlocks advanced control capabilities, improved reliability, and easier integration with other systems. Look for PLCs with open architecture for future expandability.
- Sensor integration for Real-Time monitoring: Adding sensors to monitor critical parameters – stroke length, pressure, speed, vibration – provides invaluable data for process optimization and predictive maintenance. Common sensor types include:
* Load Cells: Measure forming force, ensuring consistent part quality and preventing overload.
* Linear Encoders: Provide precise position feedback for accurate stroke control.
* Proximity Sensors: Detect part presence and trigger automated actions.
- Servo Control Systems: Replacing mechanical linkages with servo motors offers unparalleled control over ram movement. This enables:
* Variable Speed Control: Optimize cycle times for different part geometries and materials.
* Precise Dwell Control: Maintain consistent pressure during forming operations.
* Programmable motion Profiles: Create complex forming sequences for intricate parts.
- Safety System Upgrades: Modern safety systems are non-negotiable. Integrate light curtains, safety PLCs, and emergency stop buttons to protect operators and prevent accidents. Compliance with relevant safety standards (e.g., ISO 13849-1) is essential.
