Parameter
ARCH_NO Archive number
BA_NA Batch name
BA_ID Batch ID
SETPOINT Setpoint
PA_CON Feedback structure of the data request
"x": WinCC tag available; "-": WinCC tag not available
Output parameters
The following table shows the output parameters of the "FB_PA_ST" block:
Parameter
NEW_DATA 1 = New data available
QRELEASED 1= Function block released for processing
QERR_VERR 1 = Version check error
QERR 1 = Read error, data header: requested data and
read data do not match
QMON_ERR 1 = Read job monitoring timeout
QPARAMF 1 = Parameter assignment error, ID=0 or
REC_ID=0 or ARCH_NA=' ' or TIME_MON=0
QLEN_ERR 1 = Length of the read data does not correspond
to length of block outputs
QARCHERR 1 = Archive error
ACTIVE_ID Block ID
QPA_REQ Request structure
"x": WinCC tag available; "-": WinCC tag not available
In/out parameters
The following table shows the in/out parameters of the "FB_PA_ST" block:
Parameter
APF_AS APF function block version in AS
APF_OS APF function block version in OS
"x": WinCC tag available; "-": WinCC tag not available
6.3 C functions for normalization/recalculation
If a value <= 0 is entered in the NORMAMOUNT (reference quantity) cell of the
FB_PARAM_XXX archive, the parameter set with the values originally entered is used for job
control. A value in this cell of > 0 means that the data record is to be normalized automatically
and the normalized values of the individual parameters saved directly at the block.
The FB_PARAM_CALC_XXX archives are used for this normalization or indeed for data record
recalculation–either manual or triggered by the process. Recalculation can also be triggered
