Configure CEMAT V9.0 OS Clients When Faceplates Are Missing

When CEMAT V9.0 faceplates fail to appear on one WinCC OS client, verify that the client's CEMAT OS configuration is complete and that required project data has been generated and loaded. Siemens' CEMAT V9.0 SP2 Engineering Manual provides an “OS Configuration (Client)” procedure. The support thread reports that presetup is required on each client but does not identify the failed setting in the follow-up case.

Check the affected client first

The reported case involved a newly added OS client while other clients worked. That makes client-specific setup a useful first check, but does not prove that setup alone caused the symptom. Confirm the installed CEMAT V9.0 service pack and use the matching manual.

Follow the CEMAT OS Configuration (Client) procedure

The Siemens CEMAT V9.0 SP2 Engineering Manual has a dedicated “OS Configuration (Client)” chapter (starting around page 94 in the cited PDF). It covers project properties, OS Project Editor, computer properties, tag management, authorization levels, updating the WinCC project with CEMAT functions, button sets, and loading server data in a client project.

Confirm the intended OS client project and computer name correspond to the added station.
Review project properties and OS Project Editor settings against a working client and the version-matched manual. Preserve the required client project type.
Verify computer properties and tag management, then apply the documented CEMAT function and button-set configuration.
Generate and load server data as required by the project architecture, and load that data in the client project.
Save, compile, or download only the components required by the manual and site deployment procedure. Preserve station-specific settings rather than copying an entire client project.

Check language and setup consistency

CEMAT setup can include language-dependent settings. Perform those steps in the project's engineering language and follow the instructions for the installed V9.0 service pack. Do not assume a V7 or V8 procedure applies unchanged.

Verification

Start WinCC Runtime on the affected client. Open a known CEMAT object and confirm its faceplate appears, shows the expected object context, and responds to the configured tags and commands. Test another representative object and compare results with a working client. If the faceplate remains missing, record which manual sections were completed and inspect runtime diagnostics rather than repeating setup blindly.

Limitations and Operational Precautions

The discussion reports that “presetup” on each OS client resolved one case but does not identify the settings or confirm the cause in the follow-up case. The cited manual is CEMAT V9.0 SP2; use a manual matching the installed release and architecture. Back up project data and schedule OS configuration changes through site change control because client updates and server-data deployment can affect runtime availability.

Engineer FAQ

Should CEMAT client setup be checked on every OS client? The discussion reports per-client presetup, and Siemens provides a dedicated OS Configuration (Client) procedure. Follow the version-matched instructions for each client project.

Does this prove incomplete setup caused the failure? No. The follow-up does not identify the failed setting.

Can I copy a working client's settings? Use it as a comparison while preserving the target station's unique project and communication settings.

Which procedure applies? Use the CEMAT V9.0 Engineering Manual for the installed service pack and architecture.
