Alarm KRC0778

KUKA Robot KRC0778 - PROTOCOL VARIABLE MUST BE OF STRUCTURE TYPE 2114

This alarm indicates that a protocol variable declared in the KRL program is not of the required structure type 2114. The runtime environment expects a specific protocol structure definition but encountered an incompatible data type or incorrectly defined structure.

PROTOCOL VARIABLE MUST BE OF STRUCTURE TYPE 2114

This alarm indicates that a protocol variable declared in the KRL program is not of the required structure type 2114. The runtime environment expects a specific protocol structure definition but encountered an incompatible data type or incorrectly defined structure.

Common Causes

  • Protocol variable declared with wrong data type instead of the required structure type 2114
  • Missing or incorrect structure definition in the program's type declarations
  • Protocol variable initialized with incompatible data from another structure type
  • Outdated or incomplete KRL source code missing proper protocol structure imports
  • Incorrect parameter passing to a function expecting a protocol structure type 2114

Troubleshooting Steps

  1. 1Verify the protocol variable declaration matches the required structure type 2114 in the KRL source code
  2. 2Check the structure definition in the program and ensure it follows KUKA's protocol specification for type 2114
  3. 3Review variable initialization statements to confirm they use compatible data types
  4. 4Consult the relevant KUKA system documentation or interface specifications for proper protocol structure formatting
  5. 5Compare the current program against a known working reference implementation of the same protocol
  6. 6Recompile the KRL program after correcting the structure declarations and verify syntax in the KUKA IDE
