KUKA Robot KRC0578 - Invalid trigger “PRIO”
This alarm indicates that an invalid priority value was assigned to the TriggerPRIO parameter in the robot program or system configuration. The TriggerPRIO parameter controls the interrupt priority level for trigger events, and only specific predefined values are permitted by the KUKA KRC controller. The system rejected the entry because it falls outside the valid range or does not match the required format.

KUKA Robot KRC0578 - Invalid trigger “PRIO”
Invalid trigger “PRIO”
This alarm indicates that an invalid priority value was assigned to the TriggerPRIO parameter in the robot program or system configuration. The TriggerPRIO parameter controls the interrupt priority level for trigger events, and only specific predefined values are permitted by the KUKA KRC controller. The system rejected the entry because it falls outside the valid range or does not match the required format.
Common Causes
- Entered a priority value outside the valid range (typically 0-255 or controller-specific limits)
- Used incorrect data type for TriggerPRIO (e.g., string instead of integer)
- Typo or syntax error in the priority value assignment within the program or configuration file
- Attempted to use a reserved or system-protected priority level not available for user-defined triggers
- Configuration file corruption or improper editing of robot controller settings
Troubleshooting Steps
- 1Review the KUKA KRC controller documentation to identify the valid range of TriggerPRIO values for your specific controller model
- 2Locate the line of code or configuration parameter where TriggerPRIO is defined and verify the assigned value matches controller specifications
- 3Correct the priority value to fall within the permissible range and ensure it uses the correct data type (typically integer)
- 4Check for typos or formatting errors in the parameter assignment and correct syntax if necessary
- 5Clear any cached configuration data and reload the program or configuration file to ensure changes take effect
- 6If the issue persists, restore the configuration from a known working backup or contact KUKA technical support with the specific priority value attempted
