Configuring
9.7 Address space
Interface X142 (CPU)
The digital input/outputs of interface X142 are permanently assigned to the CPU.
Table 9- 6
I
Q
STEP 7 assigns the addresses automatically. You can change the addresses in the hardware
configuration of STEP 7, that is, freely assign the start address. The addresses of the channels
are derived from the start address.
You can find the addresses in the device view of the CPU under Device overview and in the
Inspector window, on the General tab under I/O addresses.
You can find a description of the control and feedback interface of the digital input/outputs at
interface X142 in Parameter assignment of digital input/outputs (X142) (Page 160).
Interfaces X122/X132 (SINAMICS Integrated)
The digital inputs and digital inputs/outputs are by default assigned to the drive (CU DO1).
You can use frame interconnection so that these digital inputs and digital inputs/outputs can
also be used by the CPU. To do so, you configure a frame 39x for automatic speed control.
Note
Telegram 393 is set by default during configuration of the SINAMICS Integrated.

You can find a description of the control and feedback interface of the frames in the
SINAMICS S120/S150 List Manual
(https://support.industry.siemens.com/cs/de/de/view/109822659/en), function diagram 2422
and 2495 to 2500. There, you will also find a description of other selectable telegrams that
are not the focus with the SIMATIC Drive Controller (for example, telegram 395).
