5.8 Connecting interfaces for communication with S7-1500R
Connecting interfaces for communication
Connect the communication interfaces of the CPUs using standardized plug connectors.
Use prefabricated connecting cables for the connection. If you want to prepare
communication cables yourself, the interface assignment is specified in the CPU manuals.
Observe the mounting instructions for the connectors.

Connecting the PROFINET ring to S7-1500

Introduction
You connect the PROFINET ring between the two R-CPUs at the RJ45 sockets of
PROFINET interfaces X1 P1 R and X1 P2 R.
Requirements
● One of the two connections of the PROFINET ring between the two R-CPUs must not
contain any other IO devices, switches or other PROFINET devices apart from
transparent media converters.
The default setting in STEP 7 is port 2 at PROFINET interface X1. Connect the
PROFINET cable to the ports of the PROFINET interfaces of the two R-CPUs. The
maximum length of the PROFINET cable is 100 m.
You can increase the distance between the two R-CPUs with an (electrical/optical) media
converter. In this case, the maximum length depends on the type of media converter
used.
You can find more information on the technical specifications, use and commissioning of
the media converter in the relevant documentation.
● You connect the IO devices, switches and other PROFINET devices to the other
PROFINET ring connection. The default setting in STEP 7 is port 1 at PROFINET
interface X1.
Accessories required
● PROFINET cable for the PROFINET ring
● Optional transparent media converter (electrical ⇔ optical)
