The Q1 and Q2 group boxes allow the user to specify the operation of the multi-function outputs.
The PWM State On Controller Stop group box contains items that allow the user to specify how the
PWM outputs behave when the controller is stopped. These items can either hold their value or default
to some value when the controller is stopped.
Note that the PWM outputs are set to the OFF state at power-up and during program download and
remain in that state until the unit is placed in RUN
