The Digital Key: Navigating the Siemens SIMOCOM U Software Download

In the world of industrial automation and drive technology, software is the invisible hand that configures, commands, and communicates with powerful hardware. For the Siemens SIMOCOM U, a now-legacy yet still widely used communication processor for SIMODRIVE and MASTERDRIVES, the software download is more than a simple file transfer—it is the critical first step toward gaining control over complex motion control systems. This essay looks into the purpose of the SIMOCOM U software, the challenges of obtaining it today, and the essential considerations for a successful installation and setup.

The Hard Truth: Discontinued & Unsupported

Siemens officially discontinued SIMOCOM U over a decade ago. It has been replaced by STARTER (for stand-alone drives) and integrated into SINAMICS Startdrive within TIA Portal. Siemens Simocom U Software Download

Because the software is obsolete:

  • It is not available for public download on Siemens' main support site (SIOS).
  • It is not supported on Windows 10 or 11 (though some users report limited success with compatibility modes).
  • Siemens no longer issues licenses or updates for SIMOCOM U.

Step 1: Install on legacy Windows (recommended)

  • Use a dedicated Windows XP (32-bit) PC or VM (VMware with physical COM port passthrough).

Part 2: The Challenge of Downloading SIMOCOM U Today

Unlike modern software distributed via the Siemens Industry Online Support (SIOS) portal with simple filters, SIMOCOM U was discontinued in the early 2010s. Siemens no longer actively promotes or updates it. This creates three primary challenges: The Digital Key: Navigating the Siemens SIMOCOM U

  1. No Direct Download Link: You will not find a button labeled "Download SIMOCOM U" on the front page of Siemens.com.
  2. Registration Requirements: Siemens requires a free account (or a paid Service & Support contract for very old archives).
  3. Version Confusion: Multiple versions exist (V3.0, V4.0, V5.0, V5.2, V5.4). The latest stable release is SIMOCOM U 5.4 SP2.

3. The Installation CDs (Physical Media)

Many automation engineers still hoard the original SIMOCOM U CDs (often yellow-labeled). Check eBay, industrial surplus sites, or automation forums for physical media. It is not available for public download on

Step 5: Reboot and Test Launch

  • After reboot, launch SIMOCOM U from Start Menu.
  • If you see an error about MSCOMCTL.OCX or COMDLG32.OCX, proceed to Troubleshooting below.

Part 1: What is Siemens SIMOCOM U?

SIMOCOM U is a PC-based parameterization and commissioning tool developed by Siemens for its older generation of variable frequency drives (VFDs) and DC drives. The "U" stands for "Universal," reflecting its ability to communicate with multiple drive series via serial interfaces (RS-232/RS-485) or a PROFIBUS network.
