Plan Four Monitoring-Only Web Clients for PCS 7 V8.2 SP2
Plan the web-serving PCS 7 station and its capacity licenses separately from monitoring-only permissions. Siemens' V8.2 multiple-station design uses an OS client as the web server, and the manual documents Web Access - Monitoring only for view-only users. For four sessions on V8.2 SP2, exact hardware and MLFBs still require the installed component baseline and existing entitlements; a generic WinCC license paragraph is not a complete purchase specification.

Use the PCS 7 Station Roles
For an OS multiple-station system, the V8.2 Web Option manual places PCS 7 Web Server on an OS client and installs the web-client license keys there. The PCS 7 licensing table separately lists OS Client, OS Web Server Basic and OS Web Server capacity. Web Option, section 5.2; Licensing, section 4.3.
This differs from quoting only a generic WinCC license paragraph. The requested system has redundant OS servers, an ES and existing clients; first identify the intended dedicated web-serving station and its present entitlements.
Prepare the Hardware and License Requirements
Create a requirements list before requesting exact order numbers:
The exact MLFBs and capacity package cannot be established from the supplied information. Obtain a version-specific bill of materials matching these requirements; do not invent a four-user package or select a generic tier without evidence.
Configure Monitoring-Only Access
The V8.2 manual documents this configuration:
- Publish the necessary data with Web View Publisher.
- On the ES, open User Administrator for the web-server project.
- Create or select the intended users/groups and assign their authorizations.
- Enable Web Navigator for those users and configure start screen and language.
- Assign Web Access - Monitoring only. The manual states that this overrides higher-level user rights.
Web Option, sections 8.2.1–8.2.2. Confirm the exact installed SP2 edition before applying the procedure.
Verification
In a controlled test, verify each of the four intended concurrent sessions can display the required process information with the correct user identity. Check that representative control actions are unavailable to monitoring-only users while the required displays remain usable.
Separately verify the agreed OS redundancy and web-station availability behavior. Four successful logins alone do not establish capacity under the required load or continuous web access during a station failure. No concurrency, permission or failover test has been performed.
Limitations and Operational Precautions
The references are V8.2 editions; exact SP2 component applicability, current entitlements, supported hardware and purchase MLFBs remain unresolved. This candidate therefore requires review before it can serve as a complete procurement list.
Back up the OS configuration and record existing authorizations before changes. Do not assume a redundant OS pair automatically makes the web-serving station redundant. Keep the rollout, permission tests and rollback within the approved operational plan.
Engineer FAQ
Does monitoring-only access eliminate capacity licensing? The permission and capacity requirements must be evaluated separately.
Can generic WinCC advice supply a complete PCS 7 bill of materials? Not without matching the actual station roles and release.
Is four-client access verified here? No; it is a stated requirement requiring capacity and runtime verification.
