Process automation
Control of an entire plant: raw material transport, recipes, dosing, heating and monitoring in one system.

In the process industry it is not enough to automate individual machines. Raw material transport, mixing, heating, process equipment and field signals must run under one control system that the operator can monitor from a single place.
We design control systems for new plants and migrate existing plants to modern control infrastructure without unnecessary production downtime.
What it includes
Process control
Sequential control of valves, motors and process equipment with interlocks and monitoring of process values.
Recipe management
Transfer of raw materials and intermediates according to the recipe to the appropriate tank, mixer or reactor.
Dosing and controlled filling
Time- and quantity-controlled filling with proportional valves.
Temperature and heating control
Control of furnace heaters and acquisition of temperature signals into the control system.
Distributed I/O and communication
Remote I/O stations distributed across the plant, connected via industrial networks (e.g. EtherNet/IP).
HMI, SCADA and data
Operator panels and SCADA for monitoring, plus transfer of process data to existing systems.
Where it is used
- Production of paints, coatings and chemical products
- Building materials and mixtures
- Glass production and processing
- Food industry and liquid dosing
How we work
- Process and requirements – together we go through the process flow, equipment and the way the plant operates.
- Control architecture – we define the PLC, distributed I/O, communication and operator interface.
- Cabinets and field level – building control cabinets, installing remote I/O stations and wiring.
- Software and integration – programming the process, recipes and screens, and connecting to existing systems.
- Testing and commissioning – on-site verification and commissioning under real process conditions.
Benefits for you
- Recipes are executed consistently, without manual errors
- An overview of the entire process from one place
- Modernisation without unnecessary production downtime
- Process data available for analysis and traceability
Equipment and technologies
