Example:
The following example (of the process image partition 3 "TPA 3") shows such a configuration
in HW Config:
● TPA 3 at output: These 50 bytes are stored consistent in the process image partition 3
(pull-down list "Consistent over -> entire length") and can therefore be read through the
normal "load input xy" commands.
● Selecting "Process Image Partition -> ---" under input in the pull-down menu means: do
not store in a process image. Then the handling can only be performed using the system
functions SFC14/15.
