235-007F

HEIDENHAIN 235-007F - PLCE partition cannot be integrated

PLCE partition cannot be integrated

The PLCE partition is currently in use and cannot be included. Another process is accessing this partition.

Root Cause Summary

HEIDENHAIN alarm 235-007F occurs when the PLCE (Programmable Logic Control Extension) partition is already active or locked by another process and cannot be integrated into the current system configuration. This typically happens during system startup, configuration changes, or when multiple processes attempt to access the PLCE simultaneously.

Safety

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

Causes and Fixes

  1. 1

    Check PLC program status

    Navigate to MOD function → PLC → Program Status to verify if any PLC programs are currently running and using the PLCE partition.

    Look for programs with status 'RUN' or 'ACTIVE' that may be blocking the partition

  2. 2

    Stop active PLC programs

    In PLC Program Status menu, select running programs and use STOP function to halt execution before attempting PLCE integration.

    Ensure stopping PLC programs won't affect critical machine functions or safety systems

  3. 3

    Clear PLCE partition locks

    Access MOD function → System → PLCE Configuration and use 'Release Partition' function to clear any remaining locks.

    Wait 10-15 seconds after releasing partition before attempting re-integration

  4. 4

    Restart PLCE integration

    Attempt the PLCE partition integration again through MOD → System → PLCE → Integrate Partition.

    Monitor the integration progress and check for any dependency conflicts

DIY Feasiblehigh confidence

Call a technician if:

  • ·Hardware communication failures persist after cable checks
  • ·PLCE partition corruption cannot be resolved with backup restoration
  • ·System resource issues indicate hardware memory problems

Prevention

  • Regularly backup PLCE configurations
  • Monitor system resource usage during operation
  • Implement proper shutdown procedures to prevent partition locks
  • Schedule periodic PLCE partition maintenance checks

Common Mistakes

  • Attempting PLCE integration while PLC programs are running
  • Not waiting for complete system startup before PLCE operations
  • Ignoring system resource warnings before integration
  • Forcing partition integration without clearing existing locks
