Description

SFB| Safety fieldbox
PN| PROFINET
IRT| Switch IRT-capable
8M12| 8 device ports for M12 connector, 8-pole
IOP| Device connection: IO parallel
V2| Version 2

2.2 Purpose
The SFB-PN-IRT-8M12-IOP-V2 safety fieldbox is designed for connection of up to 8 safety switchgear units with parallel IO signals to a PROFINET/PROFIsafe network.
A maximum of 4 BDF200-FB control panels can be connected.
Only safety switchgears are allowed to be connected for which the feedback of an external voltage can be safely excluded.
The safety signals from the connected safety switchgear are forwarded to a safety 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.
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.
BDF200-FB control panels can only be connected to device ports X4 – X7.

All fieldboxes have a good resistance against chemicals and oil. When used in aggressive media (e.g. chemicals, oils, lubricants and coolants in high concentrations) the material resistance must in each case be checked in advance for the specific application.
The sum of the total current of the individual device ports X0 – X7 for outputs A1 (power supply to devices) and DO (digital output) should not exceed 850 mA.
Protection class IP67 is only reached if all M12 connectors and blanking plugs, as well as the viewing window are properly fastening with screws.
2.4 Safety classification
– Safety inputs, 2-channel:

The SFB fulfills the requirements as PDDB according to EN 60947-5-3 in combination with magnetic sensors (2 NC contacts) up to PL e / SIL 3.
– Safety inputs, 1-channel:

– Safety outputs, 1 wire (PL d):

– Safety outputs, 2 wires (PL e):

This product must only be replaced in the application by an identical product of type SFB-PN-IRT-8M12-IOP-V2 with part no. 103040357.
The older product version has a lower safety level.
Safety response times, SFB-PN-V2
The overall reseponse time of a safety function is made up of the following:

• Response time of the connected safety switchgear
• Delay time safety fieldbox SFB-PN-V2 (WCDT_Input ≤ 20 ms)
• PROFINET/PROFIsafe transmission time
• Cycle time F runtime group F-PLC

3.2.2 Further accessories

Electrical connection

4.1 General information for electrical connection
The electrical connection may only be carried out by authorised personnel in a de-energised condition.
To supply the safety fieldbox, M12 power connectors, cables with a cross- section of max. 1.5 mm² can be connected to the fieldbox. In case of a fault, a voltage of up to 60 V can be applied to the device ports.
4.2 Notes for replacing the device
To replace a defective SFB, follow the steps below:
– Bring the machine and the SFB into a de-energised state
– Check replacement device for correct version
This product must only be replaced in the application by an identical product of type SFB-PN-IRT-8M12-IOP-V2 with part no. 103040357.
The older product version has a lower safety level.
The replacement of the older SFB-PN-IRT-8M12-IOP with the newer SFB-PN-IRT- 8M12-IOP-V2 is possible.
– The replacement device must be in the delivery state.
If necessary, carry out a “factory reset” (see 4.10).
– Set or transfer the safety address to the new device (see 4.10).
– Mount and install the unit
– Put the system and SFB back into operation
– Check all safety functions
The simple device change is only possible if the “Support device replacement without exchangeable medium” has been activated in the F-CPU for the PROFINET interface under “General / Advanced options / Interface options”.
4.3 Power supply and fuse protection
The supply voltage of the safety fieldbox is to be protected with a fuse of 10 A. In order to increase the cable cross section for the supply voltage of the fieldbox, both connections from Us and GND must be connected in parallel. Pins 1 + 4 and 2 + 3 in the fieldbox are bridged. 4.4 Internal fuse elements device ports
The device ports X0 – X7 are designed for 0.8 A continuous current and equipped in each case with an auto-resettable fuse of 1.5 A for line protection. If the fuse element is triggered, the red LED on the device port flashes with 4 pulses.
After eliminating the overload at one of the device ports, the fuse resets itself after a short cool-down phase. 4.5 Earth concept and shielding
A functional earth is connected for fault-free operation of the safety fieldbox. Earth loops must be avoided when connecting the functional earth.
The FE functional earth is normally connected via the switch. In the event of EMC problems, the fieldbox can be earthed via the separate FE connection.
An earth strap is available as an accessory.
Wiring examples for avoidance of earth loops:

  4.10 Setting the F-address and factory reset
  Carefully remove the viewing window. (Screws Torx 10)
  The screws of the viewing window are not secured.
  Keep the screws safe so that they do not get lost.
  Caution!
  Electrostatically sensitive components.
  Do not touch the printed circuit board directly.
  When you open the inspection window, ensure that no moisture or excessive humidity penetrates into the fieldbox.
  The 3 rotary coding switches behind the viewing window can be used to set the safety address and to carry out a factory reset of the SFB. F address
  1 – 999 Valid F address
  0 – 0 – 0 Factory reset

Setting of the F address

• Remove power from the SFB
• Set the desired F address in the range 1 – 999
• Resupply power to the SFB

Carrying out an SFB factory reset:

• Remove power from the SFB
• Setting of F address 0 – 0 – 0
• Resupply power to the SFB
• After 15 seconds, switch off the power of the SFB-PN again
  The IP address and the PROFINET name are deleted during a factory reset.

Set-up and maintenance

6.1 Functional testing
A check must be carried out to ensure that the projected safety function is effective.
The safety functions, configuration of the safety fieldbox and correct installation must be checked by a responsible safety specialist/safety representative.
6.2 Maintenance
The safety fieldbox operates error-free if installed and used properly.

Disassembly and disposal

7.1 Disassembly
Only disassemble the safety fieldbox if it is in de-energized state.
7.2 Disposal
Dispose of the safety fieldbox properly in accordance with national regulations and laws.

Annex system configuration

8.1 Configuration examples of the power supply
If the power supply of each fieldbox is separated and in a star configuration, the maximum cable length of a fieldbox series is limited only by the maximum permissible cable length of the field bus used.
If the power supply from fieldbox to fieldbox is looped through, the following maximum configurations apply.
3 different configurations are shown respectively for the different SCHMERSAL safety switchgear. One configuration with long cable lengths (maximum), one configuration with medium cable lengths (medium) and one configuration with shorter cable lengths (small).
The following assumptions are made for the configuration examples listed in the table:

• The examples represent maximum configurations. If individual cable lengths are shortened, larger systems are possible.
• 2 x 1.5 mm² power supply wiring and 10 A fuse protection.
• Use of SCHMERSAL cables.
• The cable lengths listed in the table between the power supply and the first fieldbox as well as the individual fieldboxes are the maximum lengths. Reducing the individual cable lengths is not critical.
• For interlocks, these designs are based on simultaneous activation of all lock and unlock functions. In the event of delayed activation of the lock and unlock function, larger systems are possible.
