H.9 Analog Input Block
The Analog Input (AI) Block (see Figure 138 below) is designed as a generalized signal conditioning function.
The output from an
AI block can be connected to the Fieldbus. The AI block receives and processes data
measured by the
Transducer Block and provides additional functions such as scaling, filtering, alarm
generation, and trending.

H.10 PID Block
The PID function offers control based on a programmable algorithm. The PID function block may be used with
a valve to control flow.
Note: See Foundation Fieldbus Specifications for more detail on use of the
PID Block.
