A failed software update or broken installation pathway broke the registry paths that point to the drive configuration .dll and data asset files. Step-by-Step Resolution Guide
: The term .acx refers to an internal Siemens data format used to store macro definitions, device models, parameters, and backup configuration data for drive objects (such as the SINAMICS S120, G120, or SIMATIC MICRO-DRIVE systems).
Engineers typically encounter this specific string inside a or an environment-blocking error message. The three most common triggers include: 1. Version and Update Mismatches
This package is a core component used by Siemens to manage configuration data for Motion Control (MC) drives within the TIA Portal environment. It is typically bundled with specific toolboxes or software extensions required to view and edit drive configurations. Siemens.mc.drives.acx.model.configuration Data.package
The physical drive has a newer firmware version than the version supported by the software's current model.configuration catalog. Resolving this requires installing the latest Support Packages (HSP) in TIA Portal.
Newer Siemens automation uses (a code-based engineering approach). The naming could relate to an internal data package for drive configuration models.
Check the exact version number requested in the error message (e.g., 2.0.0.0 ). A failed software update or broken installation pathway
Download and install the exact version of that matches your core TIA Portal installation.
Given the acx tag, the actual serialization is likely based, possibly compressed into a binary .acx file. The Data.package may be a collection of:
The error (or similar "PackageContainer") typically appears when you try to open a TIA Portal project that was created with a version of SINUMERIK MC or Startdrive that is not currently installed on your computer. The three most common triggers include: 1
This block acts as the schema or template defining parameter data types, I/O allocations, and structural limits of a drive model.
Understanding the Siemens.mc.drives.acx.model.configuration Data.package in Sinamics Drive Systems
When Siemens introduces a new drive model or firmware version, they release a Hardware Support Package. These packages append the necessary configuration data containers to your local TIA library. A broken or incomplete HSP installation can leave the software unable to parse the drive's ACX data structural model. Required Software - Siemens SiePortal
The package would integrate into the Siemens ecosystem via:
