APPENDIX

(3) Program example

The following program is designed to switc h the A/D converter module mounted

in the position of I/O number X/Y0 to X/YF to the offset/gain setting mode when

M10 is turned ON, and to return it to the norm al mode when M10 is turned OFF.

Switches to offset/gain setting mode

Switches to normal mode

Performs processing for offset/gain setting

Performs processing for normal mode

Stores setting of dedicated

instruction (G.OFFGAN) into D1.
