FSoE Master/Slave Stack

FailSafe over EtherCAT (FSoE) protocol software

The implementation of the Ixxat FSoE protocol software (Functional Safety over EtherCAT®) is characterized by efficient protocol processing, which is essential for safe drive applications, for example.

The FSoE software allows parallel instantiation, both for slave and master functionality, providing a multitude of communication options for the safe application. The clearly structured interfaces of the FSoE software also enables the use of different, non- safe EtherCAT communication interfaces, such as the HMS Anybus CompactCom modules.

  • Operating system independent - Runs with and without operating system
  • Simple connection to an insecure EtherCAT communication module through abstraction layers
  • Simplified integration and re-certification on any target system via included unit test suites and safety manual
  • Multiple instances enable the parallel integration of master and slaves on one device
  • Designed for applications according to IEC 61508 up to SIL-3
