Ladder Logic Configuration Examples
Publication 1746Ć6.8 - April 1997
Procedure
1. Create integer file N10. Integer file N10 should contain eight
elements (N10:0 through N10:7).
2. Enter the configuration parameters for all eight analog input
channels into a source integer data file N10. See Appendix B for
the channel configuration worksheet.
3. Program a rung in your ladder logic to copy the contents of
integer file N10 to the eight consecutive output words of the
1746-NI8 analog module beginning with word O:3.0.
