Heavy Vehicle Manufacturer

To automate a long-duration testing platform within the heavy vehicle production line, a dedicated control panel was developed using programmable controllers from the Nexto System. Integrated with safety controllers featuring advanced functional safety capabilities and operator interfaces, the system ensured reliable and continuous monitoring of the test station responsible for inspecting the axles and wheels of the manufacturer’s vehicles.

For this application, the NX3010 CPU was selected as the main controller. Communication between the primary PLC, safety controllers, and HMI was established through the open MODBUS TCP protocol, enabling efficient and stable data exchange.

The architecture also incorporated analog and digital I/O modules installed in the Nexto rack, ensuring precise acquisition of field signals and accurate control of test parameters. Seamless integration with the supervisory system, combined with fast field data acquisition, was fundamental to achieving high reliability, traceability, and operational efficiency throughout the testing process.
