2.1 Module description
2.1.1 Purpose, ordering code, module overview
The SFB-EC-8M12-IOP safety fieldbox is designed for connection of up to
8 safety switchgear units with parallel IO signals to a EtherCAT® / FSoE
network.
A maximum of 4 BDF200-FB control panels can be connected to the
device ports X4 – X7.

controller via the safety field bus for evaluation.
For larger safety applications, multiple fieldboxes can be connected to the power
supply and field bus in series.
WARNING
The user must evaluate and design the safety chain in accordance with the
relevant standards and the required safety level.
The non-safe IO signals of the connected devices are connected to the control
system via the field bus.
Safety switchgear with parallel IO signals can be connected to
device ports X0 - X7.

2.1.2 Safety inputs and test pulse outputs
The SFB-EC-8M12-IOP has two safety inputs and two test pulse outputs for the
supply of dry contacts at each of the 8 device ports X0 - X7.
These safety inputs are usable for:
1 channel safety switches (1oo1) with dry NC contacts
−Cross fault monitoring to all other safety inputs of the fieldbox
−Debounce filter / stable time filter for the input signal
−Supply contact by test pulse outputs with test pulse duration 1 ms
and test pulse interval 500 ms
2 channel safety switches (1oo2) with dry NC contacts
−Cross fault monitoring to all other safety inputs of the fieldbox
−Debounce filter / stable time filter for the input signals
−Supply contacts by test pulse outputs with test pulse duration 1 ms
and test pulse interval 500 ms
2 channel Safety switches (1oo2) with 24 V-PNP solid state outputs (OSSDs)
−No cross fault monitoring of the device connection cables by the
fieldbox
−Debounce filter / stable time filter for the input signals
−Supply safety inputs of the safety switchgear with 24 VDC without test
pulses
−When the OSSD is switched on, negative test pulses with a length of
10 µs to 1 ms and an interval of 20 ms to 120 s must be sent.
WARNING
For safety switchgear with electronic OSSDs, cross fault detection of the device
connection cable must be carried out by the safety switchgear!
2.1.3 Safety outputs
The SFB-EC-8M12-IOP has a safety digital output at each of the 8 device
ports X0 - X7 for controlling loads up to 0.8 A and a configurable safety signal
output for controlling 2-channel safety inputs up to 15 mA.
Safety output via 1 wire (digital output DO)
−Safety digital output (PP switching) up to PL d, for controlling
e.g. solenoids in interlocks
−Tested output, short-circuit and overload protected
Safety output via 2 wires (digital output DO and test pulse output Y1)
−Safety digital outputs (2P switching) up to PL e, for controlling
e.g. interlocks with 2-channel locking functions or for
2-channel control of safety relay modules, e.g. SRB-E-301ST
−Tested outputs, short-circuit and overload protected

12 2 Product description
2.1.4 Diagnostic input / FB interface
The SFB-EC-8M12-IOP has one diagnostic input at each of the 8 device ports
X0 - X7 for status signals of the connected safety switchgear.
At the 4 device ports X4 - X7 a FB interface is additionally integrated on this input.
The non-safe signals from command and signalling devices, e.g. the BDF200-FB,
can be transmitted via the single-wire FB-Interface interface.
FB interface automatically detects if a safety switchgear with integrated
FB interface is connected.
2.1.5 FailSafe over EtherCAT® communication
FailSafe over EtherCAT® (FSoE) is a functionally safe expansion of standard com-
munication via EtherCAT®. Communication based on FSoE is safe against altera-
tion, transmission errors and changes to the telegram sequence, etc.
The Safety Field Box SFB-EC is a FSoE module in the EtherCAT® network.
The module establishes a safety communication to a FSoE master and
transmits safety data via "FSoE" and functional data via "EtherCAT®".

2.2 Configurable functions SFB-EC
2.2.1 Parameter data sets of the device ports
Four different configurations (Types) can be selected for each device port.
The parameter data sets (Types) are used to configure the device ports for
the different safety switchgears.
A debounce filter / stable time filter is integrated for all safety inputs.
The parameters for the stable time filter are fixed for the different
parameter data set types.
The operation of the stable time filter is described in chapter 2.2.2.

INFORMATION
Further information about the connection of the different safety switchgear can be
found in chapter 2.3.
2.2.2 Description stable time filter
The stable time filter is used for bouncing safeguards.
The stable time filter automatically detects when a bouncing safeguard has come
to a standstill, in other words when it has come to a "stable" situation.
If a constant switch-on signal is received at both inputs for the duration of the
stable time, the safety function is switched on.
In difference to discrepancy time filters, the release of the safety function is only
delayed by the set stable time in the stable time filter and the release of the safety
function is not time-dependent, but only when the safeguard has actually come to a
standstill.
The stability time filter is required for safety switchgear with contacts.
In safety switchgear with electronic OSSDs, the output signals are normally filtered
internally.
Operation of the stable time filter when using 2 channel safety inputs
−The stability time filter effects an intelligent discrepancy monitoring
of the input signals.
−If one contact is switched on for the first time, the monitoring time is started.
−If both contacts are switched on for the duration of the stable time inside the
set monitoring time, the safety function is switched on.
−If the contacts do not come to a standstill, the fault message
"Discrepancy / stability time fault Device-Port X…" is displayed
after the monitoring time has passed.
−If only one contact, temporary or permanent, is switched off or the two contacts
do not come to a standstill, the fault message is also displayed after the
monitoring time has passed.

2 Product description 17
Operation of the stable time filter when using 1 channel safety inputs
−The stable time filter effects a debounce function for the input signal.
−If the contact is switched on for the first time, the monitoring time is started.
−If the contact is switched on for the duration of the stable time inside the set
monitoring time, the safety function is switched on.
−If the contact does not come to a standstill, the fault message
"Discrepancy / stability time fault Device-Port X…" is displayed after the moni-
toring time has passed.
−If the contact switches off temporary or does not come to a standstill, the error
message is also displayed after the monitoring time has passed
Frequency limit of the input signal:
The maximum switching frequency of the input signal depends on the adjusted
stability time.
The switch-on time and also the switch-off time of the input signal must both be
present at the input for at least 2 x the adjusted stable time.
The cut-off frequency of the input signal is therefore 2.5 Hz for the parameter data
sets Type A and Type B.
For the parameter data sets Type C and Type D, the cut-off frequency is therefore
0.5 Hz.
