As an expert in programming and installing process controls, Hellebrekers controls and supports various brands of PLCs. We also program the required HMIs and supply PLCs equipped with safety technology.
PLCs, or Programmable Logic Controllers, are essential in the process and manufacturing industry. A PLC is a computer specially designed to control processes and machines. Although PLC computers have a processor, memory, software and i/o just like a normal PC, they are designed to survive in a rugged industrial environment, unlike a PC.
PLCs receive data from connected sensors (input), process these data and, based on pre-programmed parameters, transmit a certain output for production processes or machines. For example, a PLC can monitor and record machine productivity or production temperature, but can also automatically start and stop processes or trigger an alarm if a machine malfunctions.

Our PLC brands
There are multitude of PLC brands, and Hellebrekers works with some of the best known, most reliable brands. We develop programs and install them on PLCs, which means we are fully familiar with the different qualities, specific features and applications of each PLC brand. Together with the client, we look for the most suitable control solution and determine the optimal PLC. Once a choice has been made, we can integrate the control system with higher-level automation layers of the automation pyramid (e.g. MES).
To build its control systems, Hellebrekers uses PLCs by the following brands:
HMI
An HMI (Human Machine Interface) is the intermediate link between a computer or machine and the human using it. In other words, an HMI allows man and machine to interact. HMIs are similar to information displays with (touch screen) controls. They translate complex process variables into a graphic representation of real-time operational information, such as visualisations of motor or valve statuses or fluid and fuel levels. Hellebrekers also designs and builds automation systems in which a PLC control system is integrated with an HMI. Using the concrete information that the HMI extracts from the PLC and visualises, decisions can be made on how to control and optimise production processes. The HMI can also be used to pass on any adjustments to the PLC, making it the primary tool for coordinating and controlling production processes or industrial systems on the factory floor.
Safety PLC
In addition to standard PLCs, Hellebrekers also writes and installs programs for Safety PLCs for new and existing production lines or plants. Just like a standard PLC, a Safety PLC can be used to automate and control industrial processes and machines. Safety PLCs, however, are specially designed to implement safety measures in a production process or plant, such as emergency stop and the person detection systems. In other words, a Safety PLC is a safety control. When critical components fail, these devices make sure that the process or plant stays safe. All Safety PLCs that we deliver to our clients meet strict international requirements.
