11.1 Applications

As well as selecting the lowest input value (common application), function code 11 can be used to memorize the lowest value over a period of time.

 

To memorize the lowest value over a period of time (set with S3 of function code 9), use function code 11 with function code 9 as shown in Figure 11-1. Create a loop with the output of function code 11 as an input to a function code 9 block and the output of function code 9 as an input to the function code 11 block. By selecting the output of the block executing function code 11 as the value that function code 9 tracks, the output of function code 11 feeds back into function code 11. As a result, this yields the same value as the output of function code 11 for the period of time that it is the input with the smallest algebraic value.
