2-6 Quick Start for Experienced Users

7. Program the configuration. Reference

Do the programming necessary to establish the new configuration word setting in the previous step.

1. Create integer file N10. Integer file N10 should contain one element for each channel used.

(For this example we only need one, N10:0.)

2. Enter the configuration parameters from step 6 for channel 0 into integer N10:0.

3. Program an instruction in your ladder logic to copy the contents of N10:0 to output word O:1.0.

On powerup, the first pass bit (S:1/15)

is set for one scan, enabling the MOV

instruction that transfers the channel

configuration word 0. This configures

and enables channel 0.
