GEFRAN Launches Retrofit Service for Machine Controls
Automation modernization extends machinery lifecycles and integrates legacy assets into digital networks via G-Mation.

GEFRAN has introduced a new retrofit service for control, regulation, and automation technology, enabling plant operators to economically upgrade legacy machinery to the latest technological standards. Rather than making costly new capital investments, these modernization measures aim to improve repeatability, increase plant availability, and significantly extend the lifecycle of existing production assets. At the same time, the service establishes the necessary technological foundation to integrate older machines into modern automation concepts and digital Industry 4.0 applications.
Tailored Modernization and System Integration
The retrofit offering is scalable, ranging from simple control software updates to complete switchboard modernization, including machine wiring. Working closely with operators and machine builders, GEFRAN first analyzes the technical and economic framework conditions—such as unstable process qualities, excessive energy consumption, or obsolete electronic components. Following the implementation of the developed concept, GEFRAN provides ongoing remote support to sustainably optimize machine performance. Users benefit from high system openness, which also facilitates the seamless integration of third-party components into the control concept.
Container Technology for the PLC
A central element of the new service is the modular G-Mation automation platform. The heart of this solution is the G-Mation P6 programmable logic controller (PLC), which provides modern Docker container technology. This container architecture allows new IT applications to be executed securely, rapidly, and in an isolated manner on already installed machines. By simply retrieving pre-built application templates for common manufacturing technologies, companies can automate their legacy machines without requiring deep interventions in the existing mechanical structure of the machinery.
Additional Context: PLC Virtualization and Edge Computing in Retrofitting
This section details technical specifications and competitive benchmarking not included in the original product announcement.
In industrial automation, the obsolescence of control components (such as PLCs, HMIs, and drive controllers) often poses a massive risk to mechanically intact machinery (brownfield assets). A retrofit solves this problem by replacing outdated Operational Technology (OT) with modern, IT-compatible hardware. The deployment of Docker containers at the PLC level, as seen in the G-Mation P6, represents a technological paradigm shift. Traditionally, software updates in monolithic PLC programs require machine downtime and carry the risk of system instability. Container technologies, however, encapsulate individual applications—such as edge analytics, MQTT gateways, or machine learning algorithms—away from the machine's hard real-time control core. This enables developers to update, add, or independently restart new IIoT functions during ongoing operation without compromising the safety-critical base control of the plant.
