Direct XML editing can break the schema validation. Instead, use the export/import feature in Startdrive.
Need to locate this package on your machine? Open TIA Portal, go to Options > Settings > Drive , and find the . There you will see the exact Siemens.mc.drives.acx.model.configuration Data.package folder. Backup this path before any software update to ensure legacy project compatibility.
: The file format or container used to distribute these updates to the engineering workstation. Implementation and Troubleshooting
Resolving this issue requires installing the missing software component, usually by updating the SINAMICS toolbox or installing the required hardware support package. 1. Identify the Required Version Siemens.mc.drives.acx.model.configuration Data.package
The package contains the necessary models, profiles, and parameterization data required to configure SINAMICS drives for motion control applications within the Siemens ecosystem.
Problem opening a project in TIA Portal – missing package files
Ensure the SIMATIC S7-1500 PLC or other controllers know exactly how to send commands and read status data from the drive. Direct XML editing can break the schema validation
: This package contains the metadata and configuration parameters required to integrate motion control (MC) drives into a TIA Portal project.
The Siemens.mc.drives.acx.model.configuration naming convention follows a standard modular hierarchy used in Siemens software deployments:
If your project manages high-precision machine tools or specialized CNC paths, the missing package is likely bundled inside the . Ensure this toolbox is installed alongside your TIA Portal environment to add the missing multi-axis drive libraries. Step 4: Clear the TIA Portal Hardware Catalog Cache Open TIA Portal, go to Options > Settings
, ensuring the PLC and the drive communicate using the correct data sets. Common Challenges: Missing Dependencies The primary reason users search for this package is a version mismatch
DeviceConfiguration
| Component | Meaning | |-----------|---------| | siemens.mc | Siemens Motion Control domain | | drives | Targets drive systems (SINAMICS family) | | acx | Automation Component XML – Siemens' data exchange format for drive parameters | | model.configuration | Domain model for configuration data (not runtime or diagnostics) | | Data.package | Indicates a composite data container – may be a .zip , .bin , or OSGi bundle |
: If this package is missing, the TIA Portal may be unable to open a hardware configuration that includes these specific drives, often prompting the user to download the corresponding Startdrive version or update.
