Enable the PCS 7 V7.1 General Reset Faceplate Button by Checking User Rights

If the General Reset button is unavailable on only one PCS 7 V7.1 OS client, first check the logged-in user's WinCC User Administrator permissions and the project's authorization assignment for that operation. PCS 7 runtime enforces operator rights by user/group and configured permission levels; the ticket reply identifies authorization as a likely cause. The missing screenshot and faceplate type prevent identifying the exact required permission, so do not grant broad administrator rights as a workaround.

Check whether the restriction follows the user or the client

Test the same account on a known-working OS client and a suitably authorized account on the affected client, following site procedures. If the restriction follows the user, review group membership and assigned operation rights. If it stays with the station, inspect client-specific project deployment, faceplate version and OS configuration.

Review WinCC User Administrator

In the PCS 7 V7.1 project, inspect the User Administrator configuration for the affected runtime user and groups. Determine the authorization level assigned to the General Reset operation by the applicable block/faceplate documentation or project configuration. Compare with a working operator account; do not assume a fixed level without identifying the faceplate and library version.

Correct the least-privilege assignment

Identify the exact faceplate/block and its required PCS 7 OS permission level from the version-matched documentation or project properties.
In WinCC User Administrator, locate the role/group used by the affected client user.
Add only the specific authorization required for General Reset to the approved role; avoid granting unrelated maintenance or administrator rights.
Ensure the user/group configuration is deployed consistently to the affected OS client using the PCS 7 V7.1 workflow.
Log in with the intended account and verify the button becomes operable only for authorized roles.

If permissions are already correct

Confirm that the affected client has the current OS project and faceplate version, that the operator is logged into the expected account, and that the reset function is enabled by the block/process state. Inspect diagnostics and compare the deployed project with a working client. Do not bypass user management by changing faceplate scripts or disabling authorization checks.

Verification

Test the authorization with both an approved operator and a user lacking the permission. Confirm the authorized account can invoke General Reset only when process interlocks and block conditions permit, while the unauthorized account remains restricted. Verify the resulting process state through the normal diagnostics.

Limitations and Operational Precautions

The ticket provides PCS 7 V7.1 but not its update level, block/faceplate type, authorization configuration or screenshot. The exact required permission cannot be named from available evidence. General Reset can alter process state; granting access or using it must follow the plant's operating and authorization policy.

Engineer FAQ

Why might only one client show the button disabled? The user/group rights or client's deployed project may differ; compare both rather than changing all stations.

Which permission level is required? It depends on the faceplate/block configuration and must be identified from the version-matched documentation or project settings.

Should I grant administrator rights? No. Assign only the required operation permission to the approved role.

How can the cause be isolated? Compare the same user across clients and authorized/unauthorized users on the affected client.

How should the reset function be tested? Verify that an authorized account can use it under valid process conditions and an unauthorized account cannot.
