The ET 200S and ET 200M distributed I/O systems may be used right into Zone 2. The ET 200iSP intrinsically safe distributed I/O 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).
1) PROFIBUS connector has a PG socket
|30° outgoing cable unit
|35° outgoing cable unit
|90° outgoing cable unit|
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 (order number: 6XV1831-2A) and the PROFIBUS connector 6ES7 972-0DA60-0XA0 to connect the ET 200iSP intrinsically safe remote I/O system to the PROFIBUS network.
The IK PI catalog ("PROFIBUS" chapter) contains the technical data, order data and the order 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.
