KUKA Robot KRC0844 - “NODE” MUST FOLLOW 2180
This alarm indicates a syntax error in the KRL program where a NODE declaration or statement is not properly positioned after instruction 2180 in the program flow. The compiler has detected that a NODE element violates the required sequencing rule within the KRL code structure.

“NODE” MUST FOLLOW 2180
This alarm indicates a syntax error in the KRL program where a NODE declaration or statement is not properly positioned after instruction 2180 in the program flow. The compiler has detected that a NODE element violates the required sequencing rule within the KRL code structure.
Common Causes
- NODE declaration placed before the required instruction 2180 in program sequence
- Incorrect nesting or indentation of NODE structure relative to preceding statements
- NODE statement appearing in wrong scope or control block level
- Missing or improperly closed block statement before NODE declaration
- NODE used in incompatible program context or instruction sequence
Troubleshooting Steps
- 1Review the KRL source code around the NODE declaration and locate instruction 2180
- 2Verify that instruction 2180 precedes all NODE declarations in the correct program sequence
- 3Check the nesting structure and ensure NODE is at the appropriate indentation level
- 4Confirm that NODE is declared within the correct scope and control block
- 5Compare the program structure against KRL syntax documentation for proper NODE placement rules
- 6Correct the NODE position or remove/restructure the offending statement, then recompile the program
