ore bit in the received counted value.
The "RestoreStatus" output indicates the current status of the restore bit from
the last received counted value frame.
You can use the output for user
-specific further processing.
You can only access the info
rmation at "CountedValueOutput_n" when a
change has been detected at the "RestoreStatus" output; in other words,
when the counted value has been received due to a restore, such as a local
time
-driven restore.
If you do not require the parameter, simply lea
ve it open.
Although all 4 counted values have their own restore bit in the data frame, for
the status at the "RestoreStatus" output only the restore bit of the first counted
value in the previously received data frame is evaluated.
tatus, however, applies to all 4 counted values.
(All counted values in the data frame always have the same status.)
For the declaration, data type, range of values, default and function, refer to
the section
Reoccurring parameters (Page 144).
The output "NewData" is always set to TRUE for one OB1 cycle when the FB
has received new data and output it to the output
/ outputs "Count-
edValueOutput_1" to "CountedValueOutput_4"
CountedValueOutput_1 (Cnt01D_S)

Since the parameter is an in
-out parameter (declaration IN_OUT), direct I/O
output of the counted value to PQD0 ...PQDn is not permitted.
It is also difficult to specify local bit memory with this parameter type and this
should not be used.
