Code XMLF-002: Attribute too long
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Attribute too long alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: The attribute data is too long. Remedy: Limit the length of the attribute data to 64 characters. If a very long attribute string is required use it as the body of the XML for example: <MYTAG> This is a string longer than 64 characters. In fact it could be many pages of text </MYTAG>. There is no limit to the length of the data in this case. A KAREL program can retrieve the data 127 characters at a time from the XML data as the string.
