Siemens 840D 61428 - Channel block: Error while creating log file -> Error code

Channel block: Error while creating log file -> Error code

The alarm can be triggered by the following measuring cycles: CYCLE996 Remedy: Causes of error: 1. Error code = A 2. Error code = B

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Insufficient disk space on the CNC controller or storage device preventing log file creation
  • File system permissions or access rights preventing write operations to the log directory
  • Corrupted or missing log file directory path configuration
  • Hardware failure of the storage device (hard drive or compact flash)
  • Log file directory path contains invalid characters or exceeds system path length limits

Troubleshooting Steps

  1. 1Check available disk space on the CNC controller; delete old log files or unnecessary data to free up storage capacity
  2. 2Verify file system permissions on the log directory; ensure the CNC user has read/write access to the configured log path
  3. 3Review the log file path configuration in the machine parameters; confirm the directory exists and the path is correctly formatted
  4. 4Run disk diagnostics or storage self-test through the controller's maintenance menu to detect hardware failures
  5. 5If error code A or B is displayed, cross-reference with the measuring cycle CYCLE996 documentation to identify cycle-specific log requirements
