Technology CPU: configuring the MPI interface

The X1-MPI/DP interface of the CPU is set by default to MPI communication with

187.5 KBit/s and to "not networked". To access the Technology CPU and the

SINAMICS S120, the transmission rate of the interface should be set to the highest

transmission rate supported by the programming device, for example 12 Mbps.

To do this, press the right mouse button to open the object properties of the

X1-MPI/DP interface and set the maximum possible transmission rate:

1. Click the "Properties" button in the "Interface" field of the "General" tab.

2. Set address 2 and select the MPI subnet from "Subnet". Click the "Properties" button.

3. Set the transmission rate to 12 Mbps in the "Network properties" tab.

Note

If the transmission rate of the X1-MPI/DP interface is set to a value larger than the

transmission rate supported by the programming device, it will no longer be possible

to access the CPU after the HW Config has been downloaded.
