Internal PROFIsafe Initialization/Operation Error

¿Qué significa E2-2 ?

The SM560-S Safety PLC has encountered a fundamental internal error during PROFIsafe initialization or general PROFIsafe operation. This critical fault indicates a problem with the safety communication stack, preventing safe operation.

• Corrupted PROFIsafe stack or firmware within the SM560-S Safety PLC during boot-up or runtime, preventing proper safety communication.
• Internal hardware failure within the SM560-S Safety PLC affecting its PROFIsafe communication controller or internal bus system.
• Incorrect or incompatible PROFIsafe configuration loaded into the Safety PLC, preventing proper initialization of the safety communication parameters.
• Severe electromagnetic interference (EMI) disrupting the internal communication buses or processor of the SM560-S PLC during PROFIsafe operations.
• Critical operating system error within the SM560-S Safety PLC impacting its ability to manage safety-critical tasks and PROFIsafe protocols.

1. 1

   1. Perform a power cycle of the entire SM560-S Safety PLC and observe if the internal PROFIsafe error clears upon restart.

2. 2

   2. Connect to the Safety PLC via engineering software and perform a complete re-download of the boot project and the safety application to the device.

3. 3

   3. Verify the integrity of the PROFIsafe configuration parameters for all connected safety devices within the engineering software (e.g., F_Source_Address, F_Dest_Address, F_iPar_CRC).

4. 4

   4. Check the PLC's diagnostic buffer via the engineering software for more detailed sub-codes or contextual error messages related to the PROFIsafe initialization failure.

5. 5

   5. If the error persists after all software and power checks, replace the SM560-S Safety PLC CPU module with a known good spare and re-download the safety application.
