Universal Analog Input Module
Procedure
1. Using the memory map function, create integer file N10. Integer file
N10 should contain eight elements (N10:0 through N10:7).
2. Using the APS software data monitor function, enter the
configuration parameters for all eight universal channels into a source
integer data file N10.
