Siemens Automation and Drives (A&D) will present new integrated safety functions for the Sinumerik 840D solution line control system at this year's EMO trade show. They meet all the requirements to SIL2 (Safety Integrity Level / IEC 61508) as well as PL d (Performance Level/EN ISO 13849-1), and they have the relevant certification.
There are now sufficient safe cams available for detecting up to 30 traversing ranges. Safe communication via standard Profibus between several Sinumerik 840D sl systems significantly simplifies plant installation. The new DP/AS-I F-Link implements a safe transition from ASIsafe to Profisafe for the first time. The compact network transition (F-Link) collects safety-related signals via the AS-i bus and transfers them via Profibus to the higher-level F controller. This enables simple and low-cost connection between the two bus systems.
With the safe digital electronics module 4F-DI/3F-DO for Profisafe, the ET 200S I/O system now has a module available that is specially tailored to the requirements of machine tools. The electronics module offers four safe inputs and three safe outputs and fulfills the requirements both of SIL2 (IEC 61508) and PL d (EN ISO 13849). It can be used in the Sinumerik 840 D sl as well as in the Sinumerik 840D powerline.
