As part of a joint project with Leuze electronic GmbH + Co KG, a PROFINET connection for a camera-based code reader was developed and certified.
The customer
Leuze electronic GmbH + Co KG is a specialist company with established application know-how in the field of sensor solutions for industrial automation. The company has had an international market presence for the past 50 years and is acknowledged as an established player.
The task
Reliable and uninterrupted product traceability is essential in packaging technology, automation, robotics and production. For this purpose, the existing product, a DCR 200i camera-based code reader, was to be fitted with a PROFINET connection without hardware modifications. The existing software platform, based on a Linux system, was to be modified accordingly and certified by an accredited PROFINET test centre. The connection was to be implemented in a generic way for multiple industrial buses.
The solution
In compliance with the specifications given by Leuze electronic, a software solution without hardware support had to be identified for the PROFINET connection. Because PROFINET makes strict demands on timing, the Linux system had to be modified accordingly and the PROFINET data traffic prioritised correctly. The modifications were not permitted to affect the already existing product.
The PROFINET interface was connected via a generic interface in order to support other Industrial Ethernet protocols in the future. A modular extension of the system is therefore always possible.
“In Solve, we found a development partner who implemented our requirements quickly and flexibly and brought the project to a successful conclusion with us.”
