Alarm KRC0396

KUKA Robot KRC0396 - <path> INVALID DATA MODULE NAME OR EXTENSION

This alarm indicates that a file path, module name, or file extension referenced in the KRC program or system configuration is syntactically invalid or does not conform to KUKA naming conventions. The controller cannot parse or locate the specified resource because the path format, module identifier, or extension is malformed or unsupported.

KUKA Robot KRC0396 - <path> INVALID DATA MODULE NAME OR EXTENSION

<path> INVALID DATA MODULE NAME OR EXTENSION

This alarm indicates that a file path, module name, or file extension referenced in the KRC program or system configuration is syntactically invalid or does not conform to KUKA naming conventions. The controller cannot parse or locate the specified resource because the path format, module identifier, or extension is malformed or unsupported.

Common Causes

  • Incorrect file extension used (e.g., .src instead of .src, or invalid extension like .txt for KRC modules)
  • Invalid characters in the module or file name (special characters not permitted in KUKA naming conventions)
  • Malformed file path syntax with incorrect separators or directory structure
  • Referenced module does not exist in the specified directory path
  • Typo in the module name or path statement within the KRC program source code

Troubleshooting Steps

  1. 1Verify the file path syntax matches KUKA KRC standard format and uses correct directory separators (typically backslashes for Windows paths in KRC programs)
  2. 2Check that the file extension is valid for the resource type (.src for source files, .dat for data files, .src for modules)
  3. 3Confirm the module or file name contains only alphanumeric characters and underscores, with no special characters or spaces
  4. 4Navigate to the specified directory path using the KRC file system browser to confirm the file exists at that location
  5. 5Review the program source code for the line referencing this path and compare against working examples or documentation for proper syntax
  6. 6Clear the alarm, correct the path or module name reference in the program, and recompile or reload the program into the controller
