Safety protocol for EtherCAT accepted by IEC committees
The Safety-over-EtherCAT protocol is referred to as FSCP 12 (Functional Safety Communication Profile) in the IEC 61784-3 specification. This standard defines the fundamental requirements of a communication system in terms of safety-relevant data transmission. It also defines potential errors and describes possible recognition and corrective measures.
The Safety-over-EtherCAT protocol was introduced in 2005 by the EtherCAT Technology Group (ETG) and has been widely used in applications worldwide. The protocol is ideal for applications up to the Safety Integrity Level SIL3 according to IEC 61508. Safety communication and standard communication use a single-bus system.
