HEIDENHAIN 140-0024 - Attribute renamed in data object Attribute

Attribute renamed in data object Attribute

The loaded configuration data comes from an older control version. An attribute was renamed by update rules during the migration process.

Root Cause Summary

This alarm is triggered when the TNC control detects that an attribute name within a system data object, machine parameter structure, or PLC configuration has been changed, typically due to software versioning differences. The control's internal consistency checking identified a renamed attribute during initialization, configuration loading, or after a software update, requiring the user to acknowledge the change and ensure all dependent references are updated accordingly.

Safety

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

Causes and Fixes

  1. 1

    Identify the renamed attribute details

    Press MOD key, navigate to System Error Messages, and record the complete alarm text including data object '%1', object type '%2', and attribute '%3' values displayed in the alarm message.

    Screenshot or write down all three parameter values as they are essential for locating the affected configuration element.

  2. 2

    Check NC software version and release notes

    Press MOD key, select System Information, note the current NC Software number. Access the Heidenhain Service Pack Notes or Software Update Documentation for your specific control model (TNC 320/530/620/640) to find the attribute rename reference table.

    Heidenhain typically provides attribute conversion tables in the 'Configuration Changes' section of service pack documentation.

  3. 3

    Update machine parameter references

    Press MOD key, enter password if required, select Machine Parameters. Search for the old attribute name identified in step 1 and verify the system has automatically remapped it to the new name. Document any parameters that require manual adjustment.

    Do not modify machine parameters without OEM authorization or complete backup of current settings.

  4. 4

    Verify PLC program compatibility

    Access the PLC programming environment (MOD > PLC > Edit) and search for any references to the old attribute name in markers, data objects, or function calls. Update to the new attribute naming convention as documented in the release notes.

    Use the PLC search function (Find Text) to locate all instances of the old attribute name throughout the PLC program.

  5. 5

    Clear alarm and verify system stability

    Acknowledge the alarm using the CE (Clear Error) key. Perform a complete control restart (power cycle or CTRL+ALT+DEL reboot). Verify the alarm does not reappear and check the error log for any additional related messages.

    After reboot, run through a complete machine initialization sequence to ensure all data objects load correctly with the new attribute names.

DIY Feasiblehigh confidence

Call a technician if:

  • ·Servo functionality is impaired after attribute renaming
  • ·Critical machine parameters show incorrect values
  • ·Multiple related alarms persist after acknowledgment

Prevention

  • Always create configuration backup before software updates
  • Document parameter changes during version upgrades
  • Maintain version compatibility records for configuration files

Common Mistakes

  • Ignoring the alarm without verifying parameter functionality
  • Restoring old configuration over updated attributes
  • Not documenting which attributes were renamed for future reference
