The analog comparator input is written in the Ladder Program Edit
Screen. Settings are made in the Parameter Settings Screen.
3-10-2 Settings in the Parameter Settings Screen
Refer to page 25 for parameter setting methods.
Comparison data 1 determines the comparison pattern. When
comparing to a constant, the constant is set for comparison data 2
next. The operator is specified last.
