Which PROFIBUS connectors can you use in Zones 1 and 2?

  • Entry
  • Associated product(s)

The ET 200S and ET 200M distributed IO systems may be used right into Zone 2. The ET 200iSP intrinsically safe distributed IO system may be used right into Zone 1.

You can use the following PROFIBUS connectors for connecting the PROFIBUS network in Zone 2 (non-intrinsically safe PROFIBUS network).

30° outgoing cable unit
(max. 1.5Mbit/s)
35° outgoing cable unit
(max. 12Mbit/s)
90° outgoing cable unit
(max. 12Mbit/s)

1) PROFIBUS connector has a PG socket

For connecting an ET200iS in Zone 1, you must configure the PROFIBUS network in this area as intrinsically safe. Therefore, the above-listed PROFIBUS connectors are not suitable.

Use the PB FC Standard Cable IS GP (article number: 6XV1831-2A) and the PROFIBUS connector 6ES7972-0DA60-0XA0 to connect the ET 200iSP intrinsically safe remote IO system to the PROFIBUS network.

The "IK PI catalog - SIMATIC NET Industrial Communication" ("PROFIBUS" chapter) contains the technical data, order data and the article numbers of other PROFIBUS bus cables and bus connectors.

In order to set up an intrinsically safe PROFIBUS segment, it is imperative to use the RS 485-IS coupler.
The manual for the RS 485-IS coupler is available in Entry ID 29306413.

Security information
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions constitute one element of such a concept. For more information about industrial security, please visit
