Beckhoff · TwinSAFE Logic FB

What does 0x40CA mean?

The 'InValueError' flag within the FB Envelope function block is TRUE, indicating a specific issue with the input value. This signifies that the input signal is not valid or within the expected operational parameters, forcing the FB into a safe state. The fault provides the FB instance and the current InValue for diagnosis.
