Additional Assembly Instances 10 and 11
In addition to the (static) assemblies (1 ... 9) that are permanently pre-
programmed in the device, the Controller has the assembly instances 10 and
11.
These simplify and speed up the transmission of the input and output image of
the PFC variable from the fieldbus Controller to the master.
