Check Network Cable Connections

Verify Ethernet cable connections at TNC control X116 connector and network switch. Check cable for damage and ensure LED indicators show link activity.

Power down control before disconnecting network cables to prevent data corruption.

Verify IP Configuration

Access MOD function, select 'System Parameters' and check MP7680 (IP address), MP7681 (subnet mask), and MP7682 (gateway). Ensure these match your network configuration.

Use ping test from TNC diagnostic screen to verify network connectivity to configuration server.

Test Network Hardware

Replace Ethernet cable and test different network switch port. Check network switch power and status LEDs.

Connect a laptop to the same network segment to verify network infrastructure is functioning.

Check Server Status

On the configuration server PC, open Windows Services and locate 'HEIDENHAIN Configuration Server' service. Verify it shows 'Running' status.

Right-click the service and select 'Restart' to force a clean restart of the configuration server.

Verify Server Port Availability

Check that TCP port 2000 (default configuration server port) is not blocked by Windows Firewall or antivirus software. Add exception if necessary.

Ensure proper firewall configuration to maintain network security while allowing TNC communication.

Review Server Event Logs

Check Windows Event Viewer for HEIDENHAIN Configuration Server errors. Look for startup failures, database corruption, or permission issues.

Server logs often contain specific error codes that can pinpoint the exact cause of communication failure.

Stop Configuration Server Service

In Windows Services, stop the 'HEIDENHAIN Configuration Server' service before attempting database repair operations.

Always backup configuration database before attempting repairs to prevent data loss.

Run Database Integrity Check

Navigate to configuration server installation directory and run 'ConfigDBCheck.exe' utility to scan for database corruption and attempt automatic repair.

Keep regular backups of the configuration database in C:\ProgramData\HEIDENHAIN\ConfigServer\Database folder.

Restore from Backup

If database repair fails, restore the most recent backup of configuration database files and restart the configuration server service.

After successful restore, immediately create a new backup and verify all machine configurations are intact.

Check TNC System Time

Press MOD key, select 'System Info' and verify current date/time. Compare with configuration server system time.

Time differences greater than 5 minutes can cause communication authentication failures.

Synchronize Time Settings

In MOD menu, access 'Date/Time' settings and manually correct TNC system time to match server time within 1-2 minutes accuracy.

Changing system time may affect active programs and logged data timestamps.

Configure NTP Synchronization

Set up automatic time synchronization using machine parameter MP7690 (NTP server address) to prevent future time drift issues.

Use the same NTP server for both TNC control and configuration server to ensure synchronized time.
