Maintenance and Servicing of Control Technology
Control technology is a key part of every modern machine, CNC system or automated production line. It includes PLC controllers, CNC controls, servo drives, frequency inverters, HMI panels, communication modules, input/output units and safety systems.
Regular maintenance and professional service of control technology are essential for reliable machine operation. Timely diagnostics, communication checks, program backups and correct parameter settings can significantly reduce the risk of unexpected downtime, production interruptions and additional damage to equipment.
At Trecon, we provide support in the maintenance, diagnostics, service and modernization of control technology on CNC machines, production lines, conveyor systems and automated cells.

What does maintenance and service of control technology include?
- Diagnostics and Technical Inspections
- Analysis of controller performance (PLC, IPC, HMI, drive modules)
- Inspection of communication links (EtherCAT, Profinet, Modbus TCP, CANopen)
- Testing input/output signals and system responsiveness
- Thermographic and voltage diagnostics
- Failures and Repairs
- Replacement of damaged components (power supplies, interfaces, CPU modules)
- Reconfiguration after replacement or upgrades
- Repair and parameter recovery in case of data loss
- Support and Modernization
- Upgrading outdated controllers and interfaces to modern solutions
- Software migration while preserving system functionality
- Consulting on adapting existing equipment to new production requirements
Maintenance as Part of Digital Readiness
With regular preventive service, you reduce:
- Unplanned downtimes and failures
- Repair costs from cascading component damage
- Risk of damage to associated drive or safety components
With properly planned maintenance, you increase:
- Reliability of the entire control system
- Precision and responsiveness of processes
- Equipment lifespan and personnel safety
