Machine Retrofit and Automation Modernisation
Replacing a mechanically sound machine only because its control system is outdated is often an unnecessary investment. With a retrofit we move the machine's PLC, operator panel and drives to current systems with available spare parts, keeping the machine in production for many more years.
Typical retrofit work
- Migration from discontinued PLCs to current ones (e.g. S7-300 → S7-1500)
- Replacing old operator panels with current HMIs
- Replacing old drives with new-generation drives
- Converting old relay-logic cabinets to PLC control
- Adding new functions, sensors or safety equipment to the machine
Retrofit or repair?
Not every old system needs a retrofit. Where spare parts are still available, repair and spare modules are often enough. When faults become frequent, parts get hard to find or new features are needed, a retrofit makes more sense. After the survey we present both options with their costs.
How we work
- 01
Survey and current state
We review the machine, existing program and electrical drawings.
- 02
Proposal
We plan hardware selection, scope and downtime.
- 03
Preparation
We prepare the program and cabinet as much as possible before the shutdown.
- 04
Installation and commissioning
We carry out the changeover during a planned shutdown and commission the machine.
Frequently asked questions
How long does the machine stop during a retrofit?
It depends on the scope. We aim to shorten on-site downtime by preparing the program and cabinet before the shutdown; the exact duration is written into the plan after the survey.
