Function Block Error

Was bedeutet Diag3:off, Diag4:1_pulse ?

This diagnostic flashing code (Diag 3 off, Diag 4: 1 uniform flash pulse) indicates a function block error within one of the TwinSAFE groups. This means that a component or logic block in the safety program is not operating as expected, potentially due to incorrect parameterization, invalid inputs, or an internal logic issue.

• An error has been detected within an active function block or application module.
• The function block failed to execute correctly or encountered an internal runtime error.
• Incorrect configuration or parameters passed to the function block.

1. 1

   Connect to the EL6900 using TwinCAT and examine the status of the TwinSAFE function blocks within the active safety project.

2. 2

   Verify the parameterization and interconnections of the function blocks identified as problematic in the safety logic, ensuring all inputs are valid.

3. 3

   Ensure that all input signals to the TwinSAFE groups are within their expected ranges and states by measuring actual signal levels if possible.
