Retrofit

PLC retrofit, troubleshooting and modernization for existing machines.

Modernization, extensions and fault correction for existing machines and plants. The goal is reliable operation, understandable diagnostics and clean documentation.

Industrial automation, water treatment, wastewater technology, HMI and SCADA

Modernize existing equipment

Existing systems can often be improved step by step: software cleanup, HMI updates, diagnostics, new interfaces, replacement of obsolete components or extension of existing machine functions.

Reduce risk during changes

Retrofit work must respect running production. Before changes are made, the current state, backups, interfaces, safety functions and operating procedures are checked as far as possible.

Troubleshooting included

Faults in PLC logic, HMI alarms, drives, safety signals and communication are analyzed systematically. The aim is not only a quick fix, but more stable and understandable operation afterwards.

Documentation and handover

Retrofit changes are documented with practical handover in mind: what was changed, why it was changed and how maintenance can diagnose the new behavior later.
