Install PCS 7 V9.0 SP3 Before Applying Update Collection 04

PCS 7 V9.0 SP3 UC04 cannot be installed directly over base PCS 7 V9.0. Siemens' UC04 Readme requires PCS 7 V9.0 SP3 or an existing SP3 system with UC01, UC02, or UC03. First obtain and install the PCS 7 V9.0 SP3 baseline through its supported upgrade procedure; then apply UC04 and verify the component levels across the system.

Why Update Collection 04 rejects PCS 7 V9.0 base

PCS 7 V9.0 SP3 UC04 is an update collection for an existing V9.0 SP3 installation; it does not upgrade a base V9.0 system to SP3. Siemens' PCS 7 V9.0 SP3 Readme lists the UC04 installation prerequisites as PCS 7 V9.0 SP3 or SP3 with UC01, UC02, or UC03. The reported installation starts from V9.0 without SP, so it is below the required baseline.

Install the service-pack baseline first

Obtain the licensed PCS 7 V9.0 SP3 installation package/media and follow its supported upgrade procedure from the installed PCS 7 V9.0 release. The UC04 download is separate: Siemens describes it as a software-update bundle and the UC04 setup updates an already installed PCS 7 V9.0 SP3 system. It cannot substitute for the SP3 setup.

Apply UC04 after PCS 7 V9.0 SP3 is installed

Back up the project and each affected ES, AS, OS server/client, and related engineering station according to the site upgrade plan. 2. Confirm the installed system and regional media correspond to the supported V9.0 SP3 upgrade path. 3. Complete the PCS 7 V9.0 SP3 installation and verify component versions. 4. Check the UC04 Readme prerequisites and product-specific notices; the Readme says to stop SIMATIC PDM Asset Service manually on an engineering station where it is enabled before UC04 installation. 5. Install UC04 using the supported setup/SIMATIC Management Console update workflow for the system. The UC04 setup applies to installed PCS 7 components rather than letting the engineer select individual products.

Licensing and media are separate from the UC requirement

The source discussion reports that SP3 setup media had to be obtained separately and that the service pack did not require a new major-version license. The opened UC04 Readme establishes the software prerequisite, not current media availability or the license entitlement for a specific contract. Confirm the applicable PCS 7 license and media entitlement with Siemens or the site's license records before scheduling the upgrade.

Verification

Before installing UC04, verify the PCS 7 component inventory reports V9.0 SP3. After installation, verify the expected UC04 level across the relevant PCS 7 components, review setup logs and system diagnostics, and perform the project and runtime checks in the approved upgrade plan. A completed UC setup on one workstation does not verify the complete distributed system.

Limitations and Operational Precautions

The user's screenshot/error text and exact PCS 7 V9.0 base update level are absent. UC04 requirements are explicit, but the exact SP3 upgrade route depends on the starting configuration, architecture, and regional media. PCS 7 service-pack and update work can affect engineering and runtime availability; use backups, a staged schedule, and a tested rollback plan. Do not install UC04 directly over base V9.0.

Engineer FAQ

Can PCS 7 V9.0 SP3 UC04 upgrade a base V9.0 system? No. Siemens requires PCS 7 V9.0 SP3 or a listed SP3 update collection as the starting point.

What must be installed first? The PCS 7 V9.0 SP3 product/service-pack baseline, using its supported installation package and upgrade procedure.

Is UC04 a full PCS 7 SP3 installer? No. Siemens describes UC04 as an update collection that updates an existing SP3 installation.

Can I select only WinCC or CFC updates during UC04 setup? The Readme says UC04 detects installed PCS 7 SP3 software and updates it; individual products cannot be selected or deselected.

Does the source settle the license cost? It reports that no new major-version license was needed for SP3, but verify the actual license and media entitlements for the system.
