F-device Parameter F_SIL Exceeds Specific Application SIL (V3 CPU)

What does 28682 mean?

Parameter "F_SIL" for F-device instance <n> in an AC500 V3 non-safety CPU PM56xx system exceeds the Safety Integrity Level (SIL) specified by the device application. This indicates a configuration that violates the safety requirements.

• The configured F_SIL (Safety Integrity Level) value for the application exceeds the maximum SIL supported by the V3 CPU.
• Overly stringent SIL requirements set for the safety function.
• Incorrect SIL assessment or configuration for the safety system.

Click steps to track your progress.

1. 1

   Check the Safety PLC configuration for F-device instance <n> and the "F_SIL" parameter.

2. 2

   Ensure the F_SIL value is within the limits defined by the specific device application's safety requirements.
