What causes KUKA Robot alarm KRC0826?

Digital output variable name is misspelled or undefined in the program. Missing or incorrect DO declaration in the variable definition section. Incorrect syntax when referencing a digital output (missing brackets, wrong parameter format). Attempting to use a DO that was declared in a different scope or module without proper import. Data type mismatch - attempting to assign non-boolean value to a digital output.

How do I fix KUKA Robot alarm KRC0826?

1. Open the KRL source file and navigate to line 2162 to identify the exact statement causing the error 2. Verify that all digital output variables are properly declared in the DECL section at the program start 3. Check the spelling and syntax of the DO variable name - ensure it matches the declaration exactly 4. Confirm that the digital output is assigned to a valid hardware output address in the program configuration 5. Review the KRL syntax for DO operations - verify correct bracket notation and parameter structure 6. If the DO is defined in another module, ensure proper referencing and that the module is included or imported correctly
