Explanation:
Counted value invalid
When evaluating "CntValIn
valid" remember that the bit might only be set for
one OB1 cycle.
The CntValInvalid output indicates whether the last received counted value
was invalid. . With "Cnt04D_R", this counts as a group display for all 4 coun
t-
ed values, see the note below.
The ou
tput shows the validity status of the most recently received counted
value in inverted form.
The output serves the following purposes:
•
Error display
•
Signal for user-specific further processing
You can, for example, react to the lack of up-to-dateness, by c
orrecting the
counted value output at "CountedValueOutput_n" with possibly lost
counting pulses.
If you do not require the parameter, simply leave it open.
Note on Cnt04D_R
Although all 4 counted values have their own status bit in the data frame, for
the
status at the output "CntValInvalid" only the bit of the first counted value in
the previously received data frame is evaluated.
This status, however, applies to all 4 counted values.
(All counted values in the data frame always have the same status.)
