Siemens.mc.drives.acx.model.configurationData.PackageContainer
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.

Problem opening a project in TIA Portal – missing package files
The string "Siemens.mc.drives.acx.model.configuration Data.package" suggests a specific technical context, likely related to Siemens Motion Control (MC) drives, specifically the SINAMICS S120 or similar converter lines where "ACX" might refer to a specific drive object or a typographical variation of a component name. Siemens.mc.drives.acx.model.configuration Data.package
Here is a breakdown of good content to structure around this topic, assuming you are creating documentation, a technical guide, or a knowledge base article.
As of 2026, Siemens is transitioning towards OPC UA FX (Field eXchange). However, the Siemens.mc.drives.acx.model.configuration Data.package remains relevant. Newer packages for drives like the SINAMICS G220 now include:
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. Siemens
The XSD schemas within the package prevent misconfiguration. For instance, if you try to map a digital output to a non-existent hardware terminal, the package triggers a compile-time error rather than a runtime fault.
In TIA Portal, drive configuration objects are stored in .library or .alz packages, not typically in that exact string format.
A typical Siemens.mc.drives.acx.model.configuration Data.package includes the following artifacts: Native OPC UA node mappings inside the ACX file
| Component | File Extension | Purpose |
|-----------|----------------|---------|
| Device Model | .acx | Hierarchical description of the drive hardware (power unit, CU320-2, motor, encoders). |
| Parameter Schema | .xsd | Defines data types for each parameter (U16, Float, I32, etc.) and allowed ranges. |
| Telegram Mapping | .telemap | Links process data words to drive internal objects (e.g., Connect PZD1 to speed setpoint). |
| Text Table | .xml | Multilingual plain-text descriptions for diagnostics and HMI displays. |
| Configuration Wizards | .dll | .NET assemblies used by TIA's "Drive Parameter Assistant" wizard. |
When you export a configured drive from TIA Portal as a library type, you are essentially creating a custom instance of this data package.
| Issue | Implication | |-------|--------------| | Firmware drift | Package must store target firmware version; mismatches may cause incomplete transfer. | | Tooling dependency | Cannot be manually edited via text editor (binary/XML schema complex). | | No real-time data | This is a configuration package, not runtime diagnostics or trace data. |
The package allows custom telegrams. In high-speed applications (e.g., 250µs bus cycle), remove unused PZDs from the data package to reduce I/O throughput.
