Operating the X136 interface as MPI

Operated like PROFIBUS
The information on wiring the connector (terminating resistors) and the rules for routing of
cables for PROFIBUS apply to this interface as well.
To do this, consult the relevant references.
Bus connector
This bus connector is used to connect the MPI bus cable to the MPI interface (X136), thus
establishing a connection to an external programming device. You should only use plugs
with a 35° cable outlet for the MPI connection.
MPI bus cable
The PROFIBUS cable specifications apply here as well; the only difference is that the cables
can be longer due to a lower transmission rate.
To do this, consult the relevant references.

Wiring PROFINET

Prerequisite
For SINUMERIK 840D sl, a PROFINET system can only be installed with the following
Control Units: NCU 720.2 PN, NCU 730.2 PN
Data Transmission Rate and Cables
For PROFINET, you require a data transmission rate of 100 Mbit/s (Fast Ethernet) full
duplex. For data transfer purposes you can use electrical twisted copper cables (twisted pair,
4-wire, 100Base-T):
● The transmission characteristics of these cables must meet the requirements of CAT5.
● The maximum length of the connections between the end device and network component
86
or between two network components (e.g. switch ports) must not exceed 100 m.
