Alarm KRC0264

KUKA Robot KRC0264 - WRONG DATA TYPE FROM TEPRO

This alarm indicates that the Safe Brake Control (SBC) module is transmitting data with an incorrect or incompatible data type to the TEPRO (Teleoperation Protocol) interface on the KRC controller. The controller's cyclic communication handler expects specific data format definitions, and when the SBC deviates from these predefined structures, the safety-critical system triggers this alarm to prevent unsafe operation.

KUKA Robot KRC0264 - WRONG DATA TYPE FROM TEPRO

WRONG DATA TYPE FROM TEPRO

This alarm indicates that the Safe Brake Control (SBC) module is transmitting data with an incorrect or incompatible data type to the TEPRO (Teleoperation Protocol) interface on the KRC controller. The controller's cyclic communication handler expects specific data format definitions, and when the SBC deviates from these predefined structures, the safety-critical system triggers this alarm to prevent unsafe operation.

Common Causes

  • Corrupted or outdated SBC firmware version incompatible with current KRC controller software
  • Hardware communication error or signal integrity issue in the SBC-to-KRC data bus connection
  • Incorrect parameter configuration in the TEPRO interface configuration files or data mapping
  • Memory corruption in the SBC module's data buffer or register definitions
  • Software version mismatch between KRC operating system and SBC control module

Troubleshooting Steps

  1. 1Verify the SBC firmware version matches the compatible version for your installed KRC software release
  2. 2Inspect all electrical connectors and communication cables between the SBC module and KRC controller for loose connections or corrosion
  3. 3Review and validate the TEPRO data type definitions in the KRC configuration files to ensure correct format specifications
  4. 4Perform a complete power cycle of the entire system, including a 30-second discharge of capacitors before restarting
  5. 5If available, update the SBC firmware to the latest certified version compatible with your KRC controller software
  6. 6If alarm persists, initiate a KRC system software integrity check or contact KUKA service support for advanced diagnostics
