Function block PID Control
The function block "PID Control " is a key component for various tasks in the process automation
and is used universally. PID blocks can be cascaded if this is necessary or requested due to differ-
ent time constants with the primary and secondary process measurement.

Function block Output Splitter
The function block "Output Splitter" generates two control outputs out of one input. Each output is
a linear image of a part of the input. A retrograde calculation function is realised by using the linear
imaging function inversely. A cascading of several Output Splitters is supported by an integrated
decision table for the combinability of inputs and outputs.
