5.1 Enhanced Function Interface - EFI
The WS0-CPU1 and WS0-CPU3 CPU modules have 2 EFI interfaces each. This
section describes the properties, the functions and the benefits of these interfaces.
The general EFI function description and the possibilities for combining SICK
products with regard to EFI are available in the corresponding manuals of SICK
products.
5.1.1 Definition
An EFI interface is a safe communication interface between SICK devices. With it
information from the sensor equipment can be read out, as well as commands
transferred to the sensor equipment.
5.1.2 Properties
 Up to 4 SICK devices are possible per EFI line, in as far as the SICK EFI-
compatible devices support this number.
 Connection of the devices using a 2-wire cable
 Various device combination possibilities
– Sensor with sensor within the same product family
– Sensor with safety controllers and network modules
– Connection of up to four WS0-CPU1 or WS0-CPU3 modules in a Flexi Link
system (see Section 4.7).
 Transferring of status information (process data) between SICK devices using an
EFI interface
 Transferring the configuration from the Setting and Monitoring Tool to the SICK
EFI-compatible devices
 Uploading the configuration from the SICK EFI-compatible devices to the Setting
and Monitoring Tool
 Activation/utilization of sensor functions
