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.

3.2 Function expansion by connecting ESPE
By connecting together individual ESPE via EFI additional applications become possible.
Example 1: Two S300 in host/guest operation
1
3
2
4
The S300 safety laser scanners are connected to a host/guest system via an EFI connec-
tion. It is then possible, for instance, to realize vehicle monitoring in two directions of
movement.
The guest (2) receives the incremental encoder values (4) from the host (1) over the EFI
interface (3). It monitors the areas for the second direction of travel as a function of the
velocity. As soon as there is an object in the protective field, it switches the OSSDs on the
host via the EFI interface to the OFF state (5).

Advantages:
•less configuration effort:
–central interface for the configuration of the system
–concurrent monitoring case switching
•less wiring costs:
–The cables for the input signals only need to be connected to the host.
–One pair of OSSDs is sufficient for the entire system.
•simplified diagnostics on the host/guest system:
–combined error messages
–central interface for system diagnostics

Example 2: Two C4000 in operation as a cascaded system
Two C4000 safety light curtains form a cascaded system. The C4000 Host (1) performs
the actual hazardous point protection on a press. The C4000 Guest (2) performs the
presence detection. The two C4000 are connected together using EFI. The OSSDs on the
C4000 Host are integrated into the machine controller (4). If the protective field of
the C4000 Guest is interrupted by standing behind or by an attempt at crawling
beneath/reaching under, the OSSDs on the C4000 Host are switched via EFI (3) to the
OFF state.

Advantages:
•Up to three safety light curtains can be connected to each other.
•No additional external circuitry required. Quick to connect.
•Resolution and protective field height may differ among the individual systems.

3.3 Function expansion using switching amplifiers
Using the UE402 switching amplifiers for C4000 and UE403 for M4000 the functionality of
the C4000 safety light curtains and the M4000 multiple light beam safety devices can be
expanded.
Example: Muting with M4000 and UE403
Two pairs of inductive muting sensors (1) connected to the UE403 detect the transport
platform. The UE403 switching amplifier (2) transmits signals via EFI (3) to the M4000
multiple light beam safety device (4) and controls the muting function.

Advantages:
•less wiring due to local connection of all signals
•less wiring between switching amplifier and ESPE due to EFI

3.4 Applications with safety controllers
Complex safety applications can be solved specifically using safety controllers.
In the insertion station with rotary table shown and the downstream robot station (1) all
the safety-related functions (hazardous point protection, hazardous area protection, door
contacts, emergency stop, restart) are realized using a Flexi Soft safety controller (2). The
ESPE are integrated into the safety application via EFI.

3
One S3000 simultaneously monitors two protective fields (1 and 2). Via EFI it signals the
states of the protective fields to the Flexi Soft safety controller (3). The safety controller
has two OSSDs for separate safe shut down. The related industrial robot is shut down by
an object in one of the protective fields. The second station continues to operate.
Advantages:
•all safety-relevant functions in one application
•one ESPE saved due to simultaneous protective field monitoring
•increased availability of the system, as only the robots related to the hazardous
situation are stopped and not the complete system

3.5 Network solutions
By integrating ESPE with the aid of the EFI gateway it is possible to bidirectionally transmit
configuration, status and diagnostics functions from the ESPE to the bus system
PROFINET IO PROFIsafe.
Using the EFI gateway, one or more ESPE or even entire applications realized with safety
controllers can be integrated into, for example, an (F)PLC.

4Technical realization
EFI is a linear bus system. Up to four devices can be connected to this bus system. The
actual number of devices depends on the related application or product family.
Twisted-pair cable with a characteristic impedance of 108 … 132 Ωis used as the bus
medium (see also chapter 6 “Technical specifications” on page 54).

4.1 Data exchange via EFI
To enable data to be exchanged via EFI, each device connected has a unique address.
7
8
7
8
8
7
In the example the S3000 Host has the address 7, the S3000 Guest the address 8. The
host receives via address 8 the status information on the OSSDs and the diagnostics
messages from the guest on contamination. The guest however receives the incremental
encoder values from the host over the address 7.
The safety controllers receive via these addresses status information on the
electrosensitive protective devices (C4000, S3000 etc.) or they control functions on the
ESPE via these addresses (muting, operating mode switching etc.).
If an EFI system is connected via an EFI gateway to a PROFINET IO, these data can be
forwarded to an (F)PLC or control tasks performed by the (F)PLC.
In the example the (F)PLC can write data to the M4000 via the routing in the EFI gateway
(address 14). I.e. muting signals can be simulated by the control system. Conversely,
status information including the output information from the M4000 (address 1) can be
transferred to the (F)PLC via the routing in the EFI gateway.

•Devices with the same address cannot be operated on the EFI at the same time.
•If there are several C4000 safety light curtains on the EFI string, the addresses for the
cascaded system are assigned automatically.
The addresses are saved in non-volatile memory in the device memory in the C4000.
The device can no longer be used as a standalone device or in a different system
position.
Reset the system position saved in the C4000 using the CDS configuration software or
using the Host-Guest Plug available as an accessory.
•In an EFI system with two safety laser scanners, set the address of one of the scanners
to guest! The procedure for addressing is described in the related operating instructions
in the chapter “Electrical installation” (S300 Mini, S300, S3000).
•For the UE4740 EFI gateway, the UE403 and the Flexi Soft FX3-CPU1, -CPU2, -CPU3 the
EFI device address can be modified using CDS or Flexi Soft Designer.
To change the addresses of the EFI gateway, connect to the EFI gateway in the CDS.
Right click the symbol for the EFI gateway and on the context menu choose Operate
service/gateway with control system.
To change the addresses of the Flexi Soft FX3-CPU1, -CPU2, -CPU3, connect to the Flexi
Soft Designer and the CPU. Right click the symbol for the CPU, a menu then appears
where you can select the required EFI device address.

4.1.2 Sending and receiving of information
Send
Each device sends exactly one item of status information with a length of up to 26 bits of
data (C4000 and M4000 senders do not provide any information, this is provided by the
C4000 or M4000 receivers).
The status information is not addressed to a specific user on the EFI string, i.e. all users on
the EFI string can receive the status information.
Receive
The product families differ in the number of items of status information received.
The maximum number of items of status information received and their addresses are
listed in the following table by product family. The table shows the items of status
information received per EFI string.

•The maximum number of items of status information received defines the number of
devices from which a device can receive information (e.g. C4000 Host from the two
guests and a safety controller).
•The devices addresses in column 4 define the devices to which a device can be
connected. The C4000 Host receives, e.g., only the addresses 2 and 3 (C4000 Guests)
and 14 (safety controllers or EFI gateways). The connection of an M4000 (1) or an
S3000 (7) is not possible.
•Also pay attention to the information given in section 4.2 “Firmware compatibility of the
EFI devices” on page 17.
