(1)
Activation of function
(2)
Positive acknowledgment: variables have been written
(3)
Reset function activation after receipt of acknowledgment
(4)
Signal change by means of FB
(5)
If function activation is reset prior to receipt of acknowledgment, the output signals are not
updated without the operational sequence of the activated function being affected.
(6)
Negative acknowledgment: Error has occurred, error code in output parameter state.
Call example
Reading of a GUD variable with the name "GUDVAR1" as an integer variable
(see also table in FB 2: Assignment of NC data type in SIMATIC data type).
