Siemens SINAMICS DCM Operating Instructions Manual page 429

The following drive objects can exchange process data:
● Control Unit (CU_DC)
● Terminal Module 15 (TM15)
● Terminal Module 31 (TM31)
● Terminal Module 150 (TM150)
● DC drive control (DC_CTRL)
Note
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
The structure of the telegram depends on the drive objects taken into account during
configuration. Configurations are permitted that do not take into account all of the drive
objects that are present in the drive system.
Example:
The following configurations, for example, are possible:
● Configuration with CU_DC, DC_CTRL
● Configuration with DC_CTRL, TM31, TM31
● etc.

Task
The drive system comprises the following drive objects:
SINAMICS DCM with the objects
● CU_DC
● DC_CTRL
Configuration settings (e.g. HW Config for SIMATIC S7)
The components are mapped to objects for configuration.
Due to the telegram structure shown, the objects in the "DP slave properties" overview must
be configured as follows:
• CU_DC
• DC_CTRL
