Siemens.mc.drives.acx.model.configuration Data.package Container Link May 2026

The string siemens.mc.drives.acx.model.configuration data.package container

refers to a specific software component or internal metadata structure used within the Siemens TIA Portal (url) environment, specifically related to the SINAMICS Startdrive (url) engineering tool. What is this Package?

This is a software "container" that holds the model and configuration data for ACX (Advanced Control eXtension) drives. In the Siemens ecosystem: MC (Motion Control): Indicates it belongs to the motion control product family.

Refers to the specific drive technology or extension (commonly associated with (url) drive macros and configurations). Package Container:

It acts as a prerequisite software module that TIA Portal must have installed to "understand" and open projects containing these specific drive models. Common Issues: "Missing Package" Errors

Users typically encounter this exact string when trying to open a TIA Portal project created on a different machine that had a newer or specific version of Startdrive or a SINUMERIK MC toolbox installed. The Symptom: TIA Portal displays an error message stating:

"Installation required: Siemens.MC.Drives.Acx.Model.ConfigurationData.PackageContainer" The Cause: You are likely missing the specific version of SINAMICS Startdrive (url) or the SINUMERIK Toolbox (url) that the original developer used. How to Resolve Check TIA Portal Version:

Ensure your TIA Portal version matches or exceeds the version used to create the project (e.g., V17, V18, V19). Install/Update Startdrive: Download and install the latest SINAMICS Startdrive

(url) package. This "container" is bundled within Startdrive installers. Check Toolboxes: If the project involves CNC, you may specifically need the SINUMERIK ONE (url) or SINUMERIK MC toolbox. Hardware Support Packages (HSPs): Sometimes, simply updating your Hardware Support Packages (url) within TIA Portal can resolve missing model errors. Are you seeing this as a "Missing Product" error when opening a project, and if so, which TIA Portal version are you currently running?

is a critical software component (metadata package) within the Siemens TIA Portal ecosystem. It is primarily associated with SINAMICS Startdrive configurations for motion control (MC) and AC drives. Siemens SiePortal Overview of the Data Package Container

: This package acts as a container for drive-specific configuration data and models used by TIA Portal to recognize and configure motion control hardware. : It is often part of the SINUMERIK MC STEP 7 Toolbox SINAMICS Startdrive installation. Common Versions : Frequently cited versions include

, which is typically required for projects created or updated in TIA Portal V17 and later. Typical Use Case: Missing Package Errors

Users often encounter this specific container name when a project fails to open in TIA Portal

with an "Installation required" error. This indicates the following: The project was created with specific Motion Control

toolboxes that are not currently installed on the workstation. The system requires the SINUMERIK MC STEP 7 Toolbox (e.g., V17 Update 12 or similar) or the SINAMICS Startdrive

package to decode the hardware model data within the project file. Siemens SiePortal Resolution Steps

2. What is Inside the Container?

When you create a drive object in a Siemens environment (e.g., TIA Portal or STARTER/SCOUT), the system generates a data.package container behind the scenes. Inside this container, you typically find:

| Component | Description | | :--- | :--- | | Device Configuration (.cfg) | Basic hardware identification: Order number of the drive unit, power unit, and Control Unit (CU320-2, CU310-2). | | Parameter List (.acx) | A flattened or structured list of all drive parameters (p-numbers and r-numbers). For example, p1300 (Control mode) or p1520 (Torque limits). | | Communication Mapping (.dft) | Defines how process data words (PZD) map between the drive and the controller. This is critical for PROFIdrive telegrams (e.g., Telegram 1, 5, 7, 9, 105). | | Firmware and Safety (.edz) | Links to the required SINAMICS firmware and Safety Integrated configurations (STO, SS1, SLS). | | Topology (.tpl) | In multi-axis systems (e.g., S120 with a 32-axis line-up), this describes which motor module is connected to which drive slot. |

3. The Role in TIA Portal and SCOUT TIA

Modern engineering relies on TIA Portal (v15.1 and above) and the integrated SCOUT TIA. Here is how the siemens.mc.drives.acx.model.configuration data.package container functions in practice:

1. Breaking Down the Naming Convention

To understand the container, one must first understand the Siemens naming hierarchy.

2. Source Code Content

6. Version Tolerance & Upgrade Path

  • The container stores its schema version and target firmware version. A newer drive firmware can accept an older container, converting missing parameters to defaults – but an older firmware will reject a newer container with a clear error.
  • This provides a safe upgrade path without surprise parameter corruption.

B. ParameterEntry.java

Represents a single parameter (e.g., Parameter 1300 = 50.5).

package siemens.mc.drives.acx.model.configuration.data.package;

import java.io.Serializable;


/**


    

  • 

    Represents a single configuration parameter entry.
*/
public class ParameterEntry implements Serializable { and device replacement.
    

    private static final long serialVersionUID = 1L;
    

    private int index;          // Parameter Index (e.g., p1300)
private double value;       // Parameter Value
private String unit;        // e.g., "Hz", "Nm", "ms"
private String description; // Readable description
    

    public ParameterEntry() {}
    

    public ParameterEntry(int index, double value, String unit, String description) 
this.index = index;
this.value = value;
this.unit = unit;
this.description = description;

    

    // Getters and Setters
public int getIndex()  return index; 
public void setIndex(int index)  this.index = index; 
    

    public double getValue()  return value; 
public void setValue(double value)  this.value = value; 
    

    public String getUnit()  return unit; 
public void setUnit(String unit)  this.unit = unit; 
    

    public String getDescription()  return description; 
public void setDescription(String description)  this.description = description; 
    

    @Override
public String toString() 
return String.format("p%d = %.4f [%s]", index, value, unit);
}

ACX Model

The "ACX" model refers to a specific line of Siemens drives designed for various applications, including industrial automation. These drives are capable of advanced control techniques and have features like high dynamics, precision positioning, and high torque density.
