4 Function blocks
The function blocks contain the basic automation functions of the field device. We distinguish
between different function blocks, e.g. Analog Input function block, PID function block
(PID controller), etc.
Each of these function blocks is used to execute different application functions. This means that
local control functions, for example, can be carried out directly in the field, and device errors such
as amplifier errors are reported to the automation system automatically.
The function blocks process the input values in accordance with their specific algorithm and their
internally available parameters. They generate output values that are made available to other
function blocks for further processing by linking the individual function blocks with each other.
