Project Download Failure - Debug Parameter OFF

¿Qué significa Enable debug OFF ?

During project download to the safety CPU, the download process may stall at 0 bytes or an error message might appear because the "Enable debug" parameter was incorrectly set to "OFF" for the safety CPU configuration and then downloaded to the non-safety CPU.

• The "Enable debug" parameter within the safety CPU's properties in the PLC project was inadvertently set to "OFF".
• A previous download or change overwrote the debug parameter setting without it being re-enabled.
• Configuration mismatch where the online CPU expects debug to be enabled for download, but the project specifies it as "OFF".
• Corrupted project settings on the engineering station causing the "Enable debug" parameter to be incorrectly interpreted during download.

1. 1

   Open the safety CPU's properties in the PLC programming software (e.g., TIA Portal).

2. 2

   Navigate to the "Protection & Security" or "Debug Settings" section and set the "Enable debug" parameter to "ON".

3. 3

   Compile and re-download the entire safety PLC project to the safety CPU.

4. 4

   Verify that the CPU transitions to RUN mode after the download without further errors.
