#HM14 Failsafe high-end controller

The Siemens Industry Automation Division is expanding its new Simatic S7-1500 generation of controllers with the most powerful failsafe CPU so far – the Simatic S7-1518F. The new failsafe CPU is suitable for high-end standard and safety-related applications in machine and plant automation. The Simatic S7-1516F CPU also supplements the range of failsafe CPUs. In the Step 7 Safety Advanced V13 engineering tool, users create their programs by using the same engineering and operating concept for both standard and safety-related tasks. Data consistency functions automatically synchronize standard and safety-related program sections.

Fehlersicherer High-End-Controller / Failsafe high-end controllerSimatic S7-1518F for high-end applications features a 10 MB (megabyte) user memory and 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 high performance and large memory allow connection of up to 128 drive axes and their isochronous operation in the range of 250 microseconds. The CPU 1518F has a bit performance of 1 nanosecond.

The new S7-151xF failsafe controllers are certified to EN 61508 (2010) for functional safety and are suitable for use in safety-relevant applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849. For IT security an additional password protection has been set up for F-configuration and F-program.

Migration tools are available for the conversion of existing failsafe automation based on Simatic S7300F/400F to the latest controller technology with Simatic S7-151xF: from the Distributed Safety V5.4 engineering tool, for example, to the TIA Portal with Step 7 Safety Advanced V13.
