Match the PCS 7 PC Station Name to the Target Computer

When a PCS 7 initial OS download fails but succeeds after changing a WinCC computer name, verify that the configured SIMATIC PC Station identity matches the target computer. Siemens documentation requires matching names for relevant station roles. Treat renaming as a clue, not a universal fix: align the project's PC Station, target Station Configuration Editor/Component Configurator, and WinCC computer properties using the procedure for the installed PCS 7 release.

Why the names must agree

PCS 7 associates a configured SIMATIC PC Station with the station name in the component configuration on the target machine. Siemens' PC Configuration manual states that the computer name and PC station name must match for OS/BATCH servers and the Engineering Station. The source reports that changing the WinCC computer name before download made one initial download succeed, but the durable correction is to configure the intended station identity consistently.

Check the project and target station

Record the Windows computer name of the target and the name configured for the SIMATIC PC Station in the project.
On the target, inspect the station name in the Station Configuration Editor/Component Configurator used by the installed PCS 7 release.
Compare that identity with the PC Station configured in SIMATIC Manager and the computer properties in the WinCC project.
Correct the configuration through the version-matched PCS 7 workflow so the target and project identities agree; do not repeatedly rename WinCC project computers as a workaround.
Retry the initial download using the standard procedure and retain the download log.

Do not confuse project name and computer identity

The WinCC project folder or project display name is distinct from the Windows/PC Station identity. Renaming the project may change behavior, but it does not prove the station assignment is correct. Siemens documentation treats matching station/computer names as part of PC-station configuration.

Verification

Confirm SIMATIC Manager recognizes the PC Station as assigned to the intended computer. After download, verify that the OS project opens on the correct target and that its configured computer properties match the machine. Keep the engineering and runtime identities aligned when cloning or replacing stations.

Limitations and Operational Precautions

The source does not state the PCS 7 version or exact rename operation. Siemens references located are V9.1 SP1/V10.0, so check names and menus in the installed release. Renaming a Windows computer or PC Station can affect network identity and configured communications; use the approved station-change procedure and back up the project.

Engineer FAQ

What name should be corrected? Align the configured PC Station name and target station/computer identity as specified by the installed PCS 7 release.

Does renaming the WinCC project solve the underlying issue? Not necessarily; the reported workaround does not establish correct station assignment.

Where is the configured name checked? In SIMATIC Manager's PC Station and the target's Station Configuration Editor/Component Configurator.

Does the exact menu path vary? Yes; use the procedure for the installed PCS 7 version.
