Industrial automation
and WAGO PLC programming

A PLC is an industrial control computer that reads inputs (temperature, presence, switch position, meter reading) and switches outputs on that basis: a pump, a valve, a light, a blind. The logic runs in the controller, not in a phone app.

In a building, this means the house keeps working on its own: heating, ventilation and shading keep regulating even when nobody touches them. In an industrial setting, the same platform controls a production line or a technological process.

WAGO is an industrial PLC platform that can be used for building automation and machine control alike. Unlike boxed smart home systems, the logic here is programmed completely freely, so there is no custom requirement that cannot be implemented.

For an industrial or agricultural project, custom technological control or a large building, the freely programmable WAGO is the stronger foundation. For a home, where a ready-made app and quick configuration matter, Loxone is more convenient. The two can also be integrated; we cover the details on the Loxone building automation page.

CODESYS is the most widely used vendor-independent PLC programming environment. A program written in it is documented and standardised, so the system can later be maintained by other specialists too, and does not depend on a single company.

The price depends on the number of controlled functions and the size of the building. The main cost elements are the controller, the input and output modules, the sensors and the labour. After a survey, we give an itemised quote, and the system can also be expanded in stages.

WAGO is a wired system, so it really pays off in new builds or renovations. When modernising an existing distribution board, it can often be fitted in retrospectively too, but for a finished, furnished flat we would rather recommend a wireless solution, such as a Loxone Air system.

Programming and commissioning a home-scale building automation system typically takes 1–2 weeks, depending on how far the electrical installation has progressed. For industrial control, the complexity of the technology decides, and we give a schedule there after a survey. The control logic is tested before going live, and fine-tuning takes place in the first weeks after commissioning.

No. Control runs locally on the WAGO controller, and the web-based visualisation also works on the local network. An internet connection is only needed for remote access.

WAGO is built on open standards: it also handles KNX, DALI, Modbus, MQTT, BACnet and OPC UA communication. This means heat pumps, solar inverters, computer systems and equipment from other manufacturers can all be integrated too.

Yes, and this is where WAGO brings the most benefit. The controller sees the solar system's current output, the household's consumption and the battery's state of charge, so it schedules the larger loads (heat pump, water heater, electric car charger) for when there is own-generated power available.

This is real money: using your own generation is always worth more than feeding it back into the grid. The measured data also shows afterwards how much stayed in the house.

Web-based visualisation runs on the WAGO controller, accessible from a browser and from a phone on the local network, and remotely over an encrypted connection. We tailor the interface to the building: floor plan view, heating zones, consumption data, alerts. There is no separate app with a monthly fee.

Yes. We take on automation of machine controls, technological processes, irrigation and climate control alike, complemented with measurement data collection and remote monitoring.

Yes, the entire control logic runs locally, and every function keeps working even if the internet connection goes down. Remote access takes place over an encrypted connection, with per-user permission management.

WAGO has a modular design: a faulty input or output module can be replaced on its own, while the rest of the system stays untouched. The modules are industrial products, available for years and obtainable from any automation supplier, so there is no dependency on a single manufacturer.

The control program keeps running unchanged with the replaced module, and no reprogramming is needed. For critical technology, it is also worth keeping a spare module on site.

Yes, it can be requested. The system can monitor operating limits (temperature, pressure, pump status, fault signals), and sends an immediate notification by email or message if there is a deviation.

On industrial and agricultural sites, this is often the most important function: a stopped pump or a rising temperature flagged in time is a cheap fault, but unnoticed it can cause serious damage.

Yes, the handover includes the CODESYS source project, the wiring diagram and the variable list, along with a short description of how each function works. This means the system can be carried forward by any automation specialist.

Yes, we take on the takeover, documentation, expansion and troubleshooting of existing WAGO and other PLC-based systems too, so you are not tied to a single contractor.

We choose according to the size of the task: for smaller building automation, a compact controller is enough, while for more complex technology and a higher point count, the PFC200 family is the right choice, with support for a range of buses and interfaces.

The input and output modules can be expanded to suit, as needed, so there is no need to oversize the system from the start. The exact type is determined by the number of controlled points recorded during the survey.
