Troubleshooting & Replacement Tips

Symptom 1 — Browser returns blank page or “WinCC Web Navigator not found”
Root cause is almost always a missing or expired license key. Open the Siemens Automation License Manager (ALM) on the WinCC server. If 6ES7658-2GG00-0XB0 shows as “Not licensed” or “Trial expired,” the license object is gone — either the USB dongle failed, or the soft license was lost during an OS migration. Replacing the license unit restores service immediately after ALM re-reads the key.

Symptom 2 — IIS service running but WinCC Web Server not publishing
Check Windows Event Viewer → Application log for WinCC WebNavigator errors. Common codes: 0x80070005 (access denied — IIS app pool identity mismatch) and 0x800706BA (RPC server unavailable — WinCC Runtime not running). Confirm WinCC Runtime is active before the Web Server can publish. If Runtime is healthy and the error persists, the license is the next suspect.

Symptom 3 — License present but concurrent user limit hit
The 6ES7658-2GG00-0XB0 covers a defined concurrent client count. If your plant has expanded web client access points since original commissioning, you may need an additional license unit or an upgraded tier. Check ALM → License Details for the “Used/Total” counter. If at capacity, a second 6ES7658-2GG00-0XB0 unit stacks the concurrent user pool.

Replacement Procedure (field-tested, 8 steps):

1. Stop WinCC Runtime on the server — do not attempt license swap with Runtime active.
2. Open Automation License Manager → right-click the expired/missing license → Transfer or Delete.
3. Insert the new USB dongle (or apply the new soft license file via ALM → License → Transfer from File).
4. ALM will auto-detect the new 6ES7658-2GG00-0XB0 license object within 30 seconds.
5. Verify license status shows “Licensed” with correct expiry (perpetual for this SKU).
6. Restart IIS: iisreset /restart from elevated command prompt.
7. Restart WinCC Runtime — allow 60–90 seconds for full initialization.
8. Open a browser on a client machine, navigate to http://[server-IP]/WinCC — process graphics should load within 15 seconds.

Firmware / Version Matching Note: This license is validated for WinCC V7.3, V7.4, and V7.5. If your server runs WinCC V8.x (Unified), this SKU does not apply — WinCC Unified uses a different HTML5-based web client architecture with separate licensing. Contact us to confirm your WinCC version before ordering if uncertain.

Reliability in Harsh Conditions

The 6ES7658-2GG00-0XB0 is a software license product, but the physical USB dongle carrier is engineered to Siemens’ industrial-grade standards. The dongle housing withstands continuous operation in server rooms subject to vibration from adjacent compressors and HVAC systems — tested to IEC 60068-2-6 (sinusoidal vibration, 10–150 Hz). Thermal tolerance covers the full industrial server room range: 0°C to +60°C ambient, with no performance degradation at sustained 55°C rack temperatures common in tropical plant environments.

The license key itself is stored in non-volatile memory with ECC error correction, meaning brief power interruptions — the kind that corrupt soft licenses on standard PCs — do not affect the dongle’s license integrity. In high-humidity coastal or chemical plant environments (up to 95% RH non-condensing), the dongle’s sealed connector maintains signal integrity without corrosion-related read failures that plague generic USB devices.

Every unit we ship has been bench-tested in our Xiamen facility: ALM recognition confirmed, license object verified against Siemens MLFB database, and dongle read/write cycles validated. We do not ship untested stock.
