5. In the Scan Time box, enter the number of units and select the time unit
to specify the time cycle of scanning HART equipment data.
For example, if you enter "1" for the number of units, and select
"(500 ms)" for the time unit, the scan time will be 1 x 500 ms = 500 ms.
This means that the current HART scan block will be executed every
500 ms.
