8080

Access Diagnostics > License Management (HMI menu path varies by operator panel). Verify the License Key Status display shows 'Valid' and matches the activated options. If status shows 'Missing' or 'Invalid', proceed to load the license key.

Do not clear the alarm without addressing the root license issue; it will re-trigger on next power cycle.

Obtain the license key file (.key or .lic) from Siemens Sales or your distributor. Use the control's Service/Configuration menu to import the license via USB CompactFlash or network. Verify the license key serial number matches the control's system ID (found in Diagnostics > System Information).

After importing the license, perform a warm restart (cycle power to the control) to reload the licensing module and validate the key against activated options. Monitor the startup sequence for license validation messages in the alarm/message list.

Verify alarm 8080 is cleared and check machine data MD10200 (ENABLE_OPTIONS) to confirm all activated option bits are now covered by valid license keys. Log the license installation date and key ID in the machine commissioning record.

Enter the machine data editor (Setup > Machine Data or via SINUMERIK Operate). Navigate to MD10200 ENABLE_OPTIONS and document which option bits are set to 1 (e.g., bit 0 for ADVANCED, bit 1 for OPTIMIZE). Cross-reference the control's commissioning documentation to identify which options are activated.

Compare the activated options list against the License Management display. If any activated option does not appear in the 'Licensed Options' list, contact Siemens to purchase and generate a license key for that option. Provide the control's system ID (HW ID) to ensure the key is bound to this specific machine.

If no license is available for an activated option, disable that option in machine data by setting the corresponding bit in MD10200 or the specific option-enable MD to 0. Save the changes and perform a warm restart.

Disabling an option may restrict NC program functionality; coordinate with the machine builder or end-user before disabling options.

After modifying machine data and restarting, verify alarm 8080 is cleared. If the alarm persists, perform a license key re-import or contact Siemens Field Service for license key regeneration.

Access Diagnostics > License Management and note the License Key Status, expiration date (if displayed), and any error messages (e.g., 'CRC Error', 'Expired'). Document the license key ID or serial number shown.

If the license is expired, contact Siemens Sales to renew the license. If the key is corrupted (CRC error or unreadable), delete the old key via the License Management menu and prepare to re-import a fresh copy from backup or from Siemens.

Deleting a corrupted license key will trigger alarm 8080 until a valid key is re-imported; do this only if a backup key file or a Siemens-supplied replacement is available.

Re-import the license key (fresh copy or renewed key) via USB CompactFlash or the network-based license import utility. Verify the import log shows 'Success' and the License Key Status changes to 'Valid'.
