PROFIsafe Safety Protocol

What is PROFIsafe?

PROFIsafe is a safety profile for transmitting safety-critical data over PROFINET or PROFIBUS. PROFIsafe meets the highest safety requirements of SIL3, thereby enabling safe communication in the process and manufacturing sectors.

PROFIsafe Products

AS-i 3.0 Gateways PROFIsafe over PROFINET or PROFIsafe over PROFIBUS provide an interface for a PROFIBUS or PROFINET fieldbus. These AS-i gateways are available in various versions with IP20 protection rating.

Standard devices

"Single Master":

1 ASi network, 1 ASi Master.

"Double Master":

2 ASi networks, 2 ASi Masters.

Safety devices

"Single Master" :
1 ASi network, 1 ASi Master.

"Double Master" :
2 ASi networks, 2 ASi Masters.

"Optional ASi Safety coupling circuit" :
2 ASi networks, 1 ASi Master.

Number of ASi networks, number of ASi Master

" yes, max. 4 A/ASi network ":
Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


"no, max. 8 A/ASi network, redundant supply ":
1 ASi power supply per ASi network. Gateway is powered in normal operation from one of the two ASi power supplies.

Should one ASi power supply fail, switching to the other ASi power supply allows all the diagnostics functions to be maintained and the unaffected ASi network continues to operate.

" no, max. 8 A/ASi network ":

1 ASi power supply per ASi network.

1 power supply, 1 gateway for 2 ASi networks, inexpensive power supplies

"USB":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann proprietary software by using the USB interface.

"Ethernet fieldbus"

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface.

"Ethernet fieldbus + Ethernet diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface or Ethernet fieldbus interface.

"Ethernet diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface.

"Ethernet diagnostic + Modbus TCP diagnostic":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software or via Modbus TCP by using the Ethernet diagnostic interface.

For a full-fledged Modbus TCP fieldbus interface use one of our Modbus TCP gateways in stainless steel or Modbus TCP gateways with integrated safety monitor.

"Ethernet fieldbus + RS 232":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface or by using an adapter cable via RS 232 interface.


"RS 232":

Access to ASi Master and Safety Monitor with Bihl+Wiedemann software by using an adapter cable via RS 232 interface.


The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device.

Diagnostic and configuration interface

Detects whether the same address has been assigned to two ASi slaves. Frequent error when using a handheld addressing device.

Recognition of duplicate ASi addresses

Checks the ASi line for interference effects such as noise, external voltages, ...

ASi fault detector

Using a C-program offers the possibility to run mini-PLC functions with a gateway.

Programming in C

An externally connected relay (contactor) can be connected via a feedback loop to the Safety Monitor for monitoring purposes.
