block will convert this to a
maximum change of the
milliamp output per execution
cycle of the block.
Example
HFigure 18 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.
ATTENTION
Reverse scaling is required for duplex control outputs.
