As of TIA Portal V15, Siemens enables the integration of the SINAMICS S120 drive as a speed or position axis via PROFINET/PROFIBUS. Siemens.mc.drives.acx.model.configuration Data.package

is a critical software component required in TIA Portal to recognize and configure SINUMERIK MC or specific drive models, with missing packages often resulting in "installation required" errors. Resolving this issue typically involves installing the corresponding version of the SINUMERIK MC STEP 7 Toolbox or updating Hardware Support Packages (HSP) via Siemens Support.

The ACX model is evolving from a pure offline engineering tool to a runtime asset administration shell (AAS) in the context of Industry 4.0. The name itself reveals its function: ParameterGroup As

: Indicates that this specific package handles the modeling of the drive's behavior and hardware configuration.

PROFIdrive telegrams (Standard Telegram 1, 352, 370, etc.) are predefined within the data package. The package tells the CPU exactly how to structure input/output data words for process data (PZD) and parameters (PKW). For more details, visit Siemens SiePortal Siemens SiePortal
