KUKA Robot KRC0816 - NO “CASE” AFTER “SWITCH” 2152
This syntax error occurs when a SWITCH statement in KRL code is missing a required CASE clause. The SWITCH-CASE-DEFAULT control structure requires at least one CASE statement to follow the SWITCH declaration with a selector expression. The program cannot compile until the missing CASE clause is added.

KUKA Robot KRC0816 - NO “CASE” AFTER “SWITCH” 2152
NO “CASE” AFTER “SWITCH” 2152
This syntax error occurs when a SWITCH statement in KRL code is missing a required CASE clause. The SWITCH-CASE-DEFAULT control structure requires at least one CASE statement to follow the SWITCH declaration with a selector expression. The program cannot compile until the missing CASE clause is added.
Common Causes
- SWITCH statement written without any following CASE clauses
- CASE keyword accidentally deleted or missing from the program
- Incorrect syntax structure where DEFAULT was used instead of CASE as the first clause
- Copy-paste error that removed CASE statements during code editing
- Incomplete refactoring of control flow logic that left SWITCH orphaned
Troubleshooting Steps
- 1Open the KRL source file and locate line 2152 or the area flagged by the compiler error
- 2Identify the SWITCH statement that triggered the alarm
- 3Verify the syntax structure follows the pattern: SWITCH(<selector>) CASE <value1>: ... ENDSWITCH
- 4Add at least one CASE clause after the SWITCH statement with appropriate value comparisons
- 5Ensure each CASE clause contains valid executable statements before the next CASE or DEFAULT
- 6Recompile the program to verify the syntax error is resolved
