Analog Input Block
Figure 5-11. Analog-Input Block
The Analog Input (AI) function block processes field device measurements
and makes them available to other function blocks. The output value from the
AI block is in engineering units and contains a status indicating the quality of
the measurement. The measuring device may have several measurements or
derived values available in different channels. Use the channel number to
define the variable that the AI block processes and passes on to linked
blocks. For further information refer to Appendix J: Analog-Input Block.
For more information on the different function blocks refer to Appendix F:
Level Transducer Block, Appendix G: Register Transducer Block,
Appendix H: Advanced Configuration Transducer Block, Appendix I:
Resource Transducer Block and Appendix J: Analog-Input Block.
