PLC / PC programming

In a PLC retrofit, we replace the outdated control system but keep the mechanics of your machine. We don’t simply copy the old code: we analyse it and convert it to the latest programming standards. Your machine keeps running for years without sudden breakdowns and can communicate with higher-level systems.

We can still help. We read the code from the existing PLC, analyse how the machine works and rewrite the software to the latest programming standards. That gives you a well-documented control system again, even if no documentation remains for the old installation.

We also modify the PLC software of machines built by other machine builders, for example to add a function, optimise a process or link a machine to other installations. We start with an analysis of the existing code and take the safety and CE conformity of the machine into account.

We are an official Beckhoff Solution Provider and also specialise in Siemens and Omron. Do you already have machines of a certain brand in your factory? We take that into account, so your maintenance team keeps working with familiar systems.

We design and program HMI interfaces tailored to your operators. Clear screens show the status of the machine, alarms appear with an understandable message and recipes or product changeovers are set up in a few clicks. User levels let you decide who may change which settings, and where needed we provide the interface in several languages. That way operators run the machine easily and safely, and solve minor faults themselves more quickly.

We make the production data of machines available through open standards such as OPC UA or MQTT. Higher-level systems such as MES or ERP can then easily collect and process the data, for real-time insight into your production.

On delivery, you receive the complete PLC code, the documentation and, where applicable, the electrical schematics. That way your maintenance team is not dependent on us and can carry on with the installation itself.

We prepare the retrofit as thoroughly as possible and test the new software in advance. Where possible, we pre-wire the new PLC using our own method, so we can install and connect it quickly on site. That keeps the changeover as short as possible.

We certainly do. The summer months and the Christmas period are usually busy weeks for us, because that is when many shutdowns are planned. It is also the ideal moment to replace critical parts, so the production line is fully up to standard again. For larger projects where a short installation time is crucial, we often keep working through the weekend.
