Configuring telegrams and drive units

5.1

Overview

The drive communication of a SINUMERIK NCU takes place via the SINAMICS Integrated
subcomponent and, if applicable, via additional connected NX modules. The scope of
functionality of the SINAMICS Integrated (or of an NX module) includes the functionality of a
SINAMICS S120 of the corresponding firmware version:
NCU firmware
V4.5
V4.7
V4.8
You can find detailed information about drive communication, e.g. function charts, in the
SINAMICS S120 List Manual for the corresponding SINAMICS version
(https://support.industry.siemens.com/cs/document/109739998/).
The standard telegram configuration of a SINUMERIK NCU (Page 104) is redundantly preset
in the TIA Portal and in the machine data and usually does not have to be modified.
Alternatively, you can switch over to a user-defined telegram configuration (Page 110).
You can also use various standard functionalities of STEP 7 (TIA Portal) in combination with
telegrams, e.g.:
● In the properties of the PLC, you can see a complete overview of the assigned I/O
addresses (Page 105).
● In the PLC tag editor, you can define telegram I/O addresses as PLC tags to access them
symbolically in the PLC program.
