1
RUN
The FB COMPARE module assumes the RUN state if a sufficient number of analog inputs
deviate from each other by no more than the allowed deviation (ValuesEqual=TRUE).
The outputs assume the following values:
Error=0
IsValid=1
CompOut=CompInX (X= smallest input that does not deviate)
2
STOP
The FB COMPARE module assumes the STOP state if the input FbRun is FALSE.
The outputs assume the following values:
Error=0
IsValid=0
CompOut=0
3
SAFE
The FB COMPARE module assumes the SAFE state if not enough analog inputs deviate
from each other by no more than the allowed deviation (ValuesEqual=FALSE) and the
DelayOutTimer has expired (DelayOutExpired=TRUE).
The outputs assume the following values:
Error=0
IsValid=0
CompOut=0
4
ERROR
If the FB COMPARE module detects an error while checking the value range of CompOut,
the FB COMPARE module switches to the ERROR state and transmits the corresponding
Diag message to the GROUP module.
The outputs assume the following values:
Error=1
IsValid=0
CompOut=0
5
RESET
The FB COMPARE 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.
The outputs assume the following values:
Error=0
IsValid=0
CompOut=0
8
DELAYOUT
If not enough analog inputs deviate from each other by no more than the allowed deviation
(ValuesEqual=FALSE), the DelayOutTimer is started with the ToleranceTime. The FB
COMPARE module assumes the DELAYOUT state as long as the DelayOutTimer has not
expired (DelayOutExpired=FALSE).
The outputs assume the following values:
Error=0
IsValid=1
CompOut = unchanged
