Implementing an electronic series connection of safety components in a laminating line from the 1990s – this was the task that zfrcontrol faced together with BERNSTEIN as part of a retrofit at a customer in the East Westphalia region. In the course of this modernisation, one or two challenges had to be solved. But in the end, the system not only meets the most modern requirements for safety technology, but now also provides extensive diagnostic data for easy troubleshooting and analysis.

This report begins in Weinsberg near Heilbronn, where the company zfrcontrol has made a name for itself in the fields of electrical design, (PLC) programming and conversion of machine controls. The company itself sees its main focus in wrapping machines and laminating lines. It was the latter that brought zfrcontrol to a customer in the East Westphalia region.
