A new range of Logo! logic modules has been equipped by the Siemens Industry Automation Division with an integral Ethernet interface. The two new basic devices — Logo!12/24 RCE and Logo!230 RCE — with communication and network capabilities enhance the Siemens portfolio with logic modules geared towards meeting demanding applications. The performance of the new devices has also been significantly improved, the company says. The program capacity has been doubled to 400 function blocks, and a wide range of new practice-oriented functions has been introduced, including macro functions for recurring program sequences, and data logging functions for documentation and evaluation purposes. Up to eight of the new logic modules can be networked using standard Ethernet switches. Together with the Ethernet interface and the new SD card reader, the new modules have a width of six MW (modular width) and thus 108 millimetres. The standard devices with a width of four MW are still used for simple applications.
