4 Analog Input function block
In the Analog Input function block (AI function block), the process variables from
the Transducer Blocks "TRANSDUCER_CH1" (flow channel 1, base index 1200),
"TRANSDUCER_ CH2" (flow channel 2, base index 1300) and "TRANSDUCER_ TOT"
(totalizer, base index 1550) 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
