Basics
This chapter describes the possibilities offered by the Enhanced Function Interface (EFI).
The Enhanced Function Interface (EFI) was developed to implement safe communication
between ESPE, Flexi Soft modular safety controller or EFI gateway.
However, EFI is more than an interface for connecting together SICK devices. EFI expands
the functionality of the individual protective devices.
Using protective devices connected with EFI, safety-related applications can be
implemented that would otherwise only be possible with a large amount of circuitry or
extensive installation effort. These applications include, for example, simultaneous
protective field monitoring using the S3000 safety laser scanner, operating mode
switching on the C4000 or sampling status signals (e.g. for a contaminated front screen).
Status and control information is exchanged between devices via EFI. The applications can
be integrated into higher level bus systems using EFI gateways.
In addition the concurrent configuration of the devices in a project is possible.
You will find the advantages of EFI in SICK safety systems only.
