Target area for the read data.
It must have the same length as the area
that you configured for the selected DP
slave/PROFINET IO component. Only the
data type BYTE is permitted.
Please refer to SFC 14 - DPRD_DAT - Read consistent data.
15.3.2
FB 21 - SETIO - PROFIBUS/PROFINET write all Outputs
With the FB 21 SETIO you consistently transfer the data from the source area indicated
by
OUTPUTS
to the addressed PROFIBUS DP slave/PROFINET IO device, and, if nec-
essary, to the process image (in the case where you have configured the affected
address area for the DP standard slave as a consistency area in a process image). In
doing so, FB 21 calls the SFC 15 DPWR_DAT. The source area must have the same
length that you configured with for the selected component. In the case of a DP standard
slave with a modular structure or with several DP IDs, you can only access the data for
one component/DP ID with an FB 20 call each time at the configured start address.

FB 22 - GETIO_PART - PROFIBUS/PROFINET read a part of the Inputs
With the FB 22 GETIO_PART you consistently read a part of the process image area
belonging to a PROFIBUS DP slave/PROFINET IO device. In doing so, FB 22 calls the
SFC 81 UBLKMOV.
