Powerful, Failsafe Controller Technology for Standard and Safety-Related Applications
Jane Alexander | June 9, 2014
Siemens Industry has introduced the SIMATIC S7-1518F, a failsafe controller with a bit performance of 1 nanosecond. Designed to increase flexibility, safety, efficiency and productivity at the plant-floor level, it’s suitable for high-end standard and safety-related machine and plant automation applications.
The S7-1518F has four communication interfaces: a Profinet interface with a 2-port switch for communication with the field level, two Profinet interfaces and one Profibus interface. The unit also accommodates up to 128 drive axes, operates isochronously in 250 microseconds and has 10MB of memory.
Siemens has also introduced the SIMATIC S7-1516F CPU. Programs can be easily created with the Step 7 Safety Advanced V13 engineering tool that incorporates drag & drop, project-wide cross-reference list, safety administration editor, online/offline comparator and additional integrated-system-support functions. The tool creates fail-safe applications and delivers the same engineering and operating concepts for both standard and safety-related tasks.
Both CPUs are certified to EN 61508 (2010) for functional safety and are suitable in safety-relevant applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849. Additional password protection has been set up for F-configuration and F-program for IT security.
