Example
Figure 2-10 shows a Function Block Diagram configuration using an AO function block to retransmit an
analog input value. In example A, the output is from a SPP block to an external controller via the AO block.
In example B, the mA output is 4 mA for an analog input of 2000.
NOTE: Reverse scaling is required for duplex control outputs.
