ST100 Series Profibus PA
Analog Input Blocks Description
There are 4 AI blocks; three of those blocks will be described in this section the fourth one will be described in the Totalizer Blocks Description
section. The three blocks described in this section are Flow, Temperature and Pressure.
The AI blocks are the ones that present the process variable data that gets mapped to the DPV0 PROFIBUS layer for the cyclic transmission to the
PROFIBUS master.
Flow Analog Input (AI) Block
The Flow AI block is the instrument’s primary output variable. This block gets its input from the Flow Transducer block.
