Automation for Food Production
Modern production plants in the food industry are highly automated: PLC controllers coordinate conveyors, filling machines, packaging machines and sorting systems. When this automation fails, the entire line stops. Our team combines automation engineering with practical plant experience — we understand not only the software, but also the machine behind it.
PLC Programming and Parameterization
We program and parameterize PLC controllers for your production plants. Whether initial commissioning, adapting existing programs or complete reprogramming — we work with common control systems and adapt the logic to your production processes. Including recipe management, batch tracking and interfaces to higher-level systems.
PLC Migration
Outdated controllers are one of the most common causes of production downtime: spare parts no longer available, software no longer compatible, no support from the manufacturer. We migrate your existing control system to current platforms — with minimal production interruption and complete functional testing.
SCADA and Process Visualization
Clear visualization of your production processes: plant states, alarms, production data — all at a glance. We implement SCADA systems and operator interfaces that make daily work easier for your staff.
Pneumatics
Valve terminals, cylinders, compressed air supply, throttle valves — pneumatic systems are ubiquitous in the food industry. We install, maintain and repair pneumatic components and perform systematic troubleshooting for pressure losses and malfunctions.
