Consistent Data Access
Consistent data access >4 bytes is now also possible without SFC 14/15. The consistent data
area of a DP slave is configured in HW config as part of the process image for this purpose.
The operating system then transfers this data consistently during process image updating, and
you can access it via load and transfer commands in the process image. This is a much easier
and effective way (low runtime load) to access consistent data. This makes an efficient integra-
tion and configuration of e.g. drives and other DP slaves possible
