5-2 Programming Examples
Procedure
1. Create integer file N10. Integer file N10 should contain eight
elements (N10:0 through N10:7).
2. Using the programming software, enter the configuration
parameters for all eight thermocouple channels into data file
locations N10:0 through N10:7.
3. Program a rung in your ladder logic to copy the contents of
integer file N10 to the eight consecutive output words of the
thermocouple module beginning with O:3.0.
Initial programming example
On power up, bit S:1/15 is set for the first program scan. During the
first program scan, the configuration data in N10:0 through N10:7 will
be sent to the 1746-NT8 channel configuration words.
