VALUE MISSING 2179
This alarm indicates that a required value or parameter is missing from a KRL program object during execution. The system expected a specific parameter or variable value at @P1@ but could not find or access it, preventing the program from continuing.
Common Causes
- Missing or undefined parameter in a function or module call
- Variable declared but not initialized before use
- Incorrect parameter passing syntax in function invocation
- Data structure or array element referenced without proper initialization
- Module or include file not loaded or improperly linked
Troubleshooting Steps
- 1Check the KRL program source code at the location indicated by @P1@ for missing parameter declarations
- 2Verify all variables are properly initialized with default values before being referenced in expressions
- 3Review function calls to ensure all required parameters are provided in the correct order and format
- 4Confirm that all necessary modules and include files are properly declared and linked in the program
- 5Use the KUKA IDE debugger to inspect variable values and parameter states at the point of failure
- 6Recompile the program after corrections and clear any cached bytecode before restarting execution
