Walter De Battista, head of Recom’s hardware engineering department, comments: “ABB proposed that we use AC500-S PLC in this application, which initially was not included in our project. Following this suggestion, we implemented a fully integrated control in the machine. This saved a lot of time thanks to the tips provided by ABB's engineers about software development and industrial drive commissioning.”
Recom’s programmers benefitted from already knowing the IEC 61131-3 programming language, which is used to set-up the PLC software. Also the memory card within the ABB industrial drives enables the application software to be stored. Should an extreme temperature or variable power supply damage the drive, it can be replaced and the memory card inserted to get the crane operational quickly. In the past, the customer could only return the failed drive or buy a new one already pre-set for their application, which was time-consuming to complete.
