If the FB ADD module detects an error when checking the value range of AnalogOut during
the addition, the FB ADD module switches to the ERROR state and transmits the
corresponding Diag message to the GROUP module.
The outputs assume the following values:
Error=1
AnalogOut=0
5
RESET
The FB ADD module assumes the RESET state if no further error is pending after an error
has occurred and the ErrAck input of the corresponding group is set to TRUE.
