XML_TAG_SIZE

Tag too long

Fanuc · R-30iA R-30iB Controller

What does XML_TAG_SIZE mean?

This error occurs when an XML tag within the parsed file exceeds the maximum allowed length, preventing the XML parsing process from completing successfully. This limitation helps manage memory and processing resources.

Common Causes

  • An XML tag name exceeds the defined character limit of the parser.
  • The configuration file contains an unusually long identifier for an XML element.
  • Software limitation on the maximum length of XML tag identifiers.
  • Data corruption during file transfer resulting in an extended tag name.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Shorten the XML tag name in the configuration file.

  2. 2

    Verify the character count of the offending XML tag in the configuration file.

  3. 3

    Ensure the configuration file adheres to the specified XML schema or format.

  4. 4

    Re-export or re-generate the configuration file if it was automatically created.

  5. 5

    Check parser documentation for the specific maximum tag name length.
