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.
