5 Analog Input function block
In the Analog Input function block (AI) the process variables from the Transducer Block are
prepared for the subsequent automation functions (e.g. scaling, limit value processing). The
automation function is defined by the connections of the outputs.
OUT = output value and output status of the Analog Input function block
