HEIDENHAIN 235-009C - Zwei Geräte am HSCI-Strang vertauscht

Zwei Geräte am HSCI-Strang vertauscht

Zwei Geräte im HSCI-Strang sind gegenüber der Projektierung vertauscht. Die Hardware-Reihenfolge stimmt nicht mit der Konfiguration überein.

Root Cause Summary

HEIDENHAIN alarm 235-009C indicates two HSCI devices are physically swapped compared to their configured positions in the system. The TNC control detected device serial numbers at different HSCI addresses than expected during system initialization.

Safety

  • Refer to Heidenhain service manual
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Access HSCI Configuration Parameters

    Navigate to MOD > Machine Parameters > enter password > search for MP72xx series parameters related to HSCI device configuration.

    Use the parameter search function with 'HSCI' keyword to quickly locate relevant parameters

  2. 2

    Compare Physical vs Configured Devices

    Check the alarm message for device types and serial numbers, then verify MP7200.x parameters match the actual HSCI device installation sequence.

    Document original parameter values before making changes

  3. 3

    Correct Device Type Parameters

    Modify the appropriate MP72xx parameters to match the physical HSCI device arrangement, ensuring device types correspond to correct HSCI addresses.

    Cross-reference device serial numbers from alarm message with physical device labels

  4. 4

    Restart Control and Verify

    Perform a complete TNC restart (Ctrl+Alt+Del) to reinitialize HSCI communication and verify alarm clears during startup sequence.

DIY Feasiblehigh confidence

Call a technician if:

  • ·Parameter changes don't resolve alarm after multiple restart attempts
  • ·Physical cable inspection reveals damaged HSCI connectors
  • ·Multiple related HSCI communication alarms persist

Prevention

  • Document HSCI device configuration before making changes
  • Label HSCI cables with device addresses
  • Perform regular HSCI cable connection inspections
  • Maintain backup of working machine parameters

Common Mistakes

  • Changing parameters without documenting original values
  • Disconnecting HSCI cables with power on
  • Not following proper daisy-chain sequence
  • Ignoring device serial number verification
