Ladder Program
The following data define extend and retract profiles for the
sample program:
Extend position setpoints #N7:0
Extend voltage values #N7:10
Retract position setpoints #N7:20
Retract voltage values #N7:30
This ladder program loads profiles into the module through the output
image table. (The 1746-QV module is in slot 1 for this example.)
