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.

3. Program a rung in your ladder logic to copy the contents of integer

file N10 to the eight consecutive output words of the universal

module beginning with O:3.0.
