Technical Write‑Up: Siemens MC Drives ACX Model Configuration – Data Package Container Download 1. Overview In the Siemens Motion Control (MC) ecosystem, the string siemens.mc.drives.acx.model.configuration data.package container download refers to a structured process for transferring a complete drive configuration package—encapsulated in an ACX (Automation Component eXchange) container—from an engineering system to a target drive device or controller. This mechanism is fundamental for deploying parameter sets, firmware updates, topology settings, and application‑specific logic to Siemens SINAMICS drives and SIMOTION controllers. 2. Key Concepts | Term | Description | |------|-------------| | Siemens MC | Motion Control product family (e.g., SIMOTION, SINUMERIK, SINAMICS). | | Drives | SINAMICS drive units (S120, G120, S210, etc.). | | ACX | Automation Component eXchange – a data format based on XML/ZIP for exchanging configuration, commissioning data, and engineering objects between Siemens tools and devices. | | Model Configuration | The hierarchical, object‑oriented representation of drive parameters, functions (e.g., positioning, synchronism), and hardware topology. | | Data Package Container | A compressed archive (.acx) containing all engineering data: device parameters, communication settings, technology objects, and optionally firmware. | | Download | The action of transferring the container from TIA Portal, STARTER, or SCOUT engineering software to the non‑volatile memory of the drive/controller. | 3. Typical Workflow

Engineering

Create/configure the drive in TIA Portal or SCOUT (e.g., SINAMICS S120). Define motor parameters, control structure (speed/position/torque), fieldbus (PROFINET, EtherNet/IP), and safety functions.

Generate ACX Container

The tool exports the configuration as a .acx file – a ZIP archive with XML documents, binary data, and checksums. Example filename: Drive_Unit_1.acx .

Transfer / Download

Connect via Ethernet, USB, or onboard PROFINET interface. Initiate “Download to device” in the engineering software. The tool transfers the ACX container to the drive’s persistent storage (e.g., memory card or internal flash). | | ACX | Automation Component eXchange –

Activation

Drive verifies container integrity and compatibility. On next power‑up or by command, the drive adopts the new model configuration.

4. Why Use a Container‑Based Download? via libsiemens or Openness API)

Reproducibility – Entire drive setup is versioned and deployable to multiple units. Offline/Online Sync – Engineering remains consistent with actual device state. Firmware & Parameters Together – Avoids dependency mismatches. Safety Integration – ACX can include safety parameters with CRC protection.

5. Example Command / Tool Context In automation scripts or advanced diagnostics (e.g., via libsiemens or Openness API), a pseudo‑call might appear as: # Conceptual Python-like invocation siemens.mc.drives.acx.model.configuration.import( container_path="C:\\Projects\\Line1_Drive.acx", target_device="192.168.1.10", download_mode="complete" )
