				X		X			DO5FlSpeed is how long it takes for the actuator motor to move one cycle of travel
									from closed to open. This value would be required if DO5Type were configured to
									either Float_Open or Float_Close.
				X		X			DO6FlSpeed is how long it takes for the actuator motor to move one cycle of travel
									from closed to open. This value would be required if DO6Type were configured to
									either Float_Open or Float_Close.
				X		X			DO7FlSpeed is how long it takes for the actuator motor to move one cycle of travel
									from closed to open. This value would be required if DO7Type were configured to
									either Float_Open or Float_Close.
				X		X			DO8FlSpeed is how long it takes for the actuator motor to move one cycle of travel
									from closed to open. This value would be required if DO8Type were configured to
									either Float_Open or Float_Close.
				X	M	X			DO1PWMPeriod is a intermittent voltage pulse whose width varies in proportion to
									the desired actuator position. The PWM signal has three parameters that have to be
									configured in order for the output to function correctly. The period, is the overall pulse
									lenegth in seconds. The percent_time (signal presence) is the zero percent position
									of the actuator output. The actuator requires this signal (pulse width) sent once every
									period, so that it knows that it is still connected to the controller and where the zero
									position starts. The variable width (delta_time) portion is incremented in proportion to
									the signal percentage. There are 255 increments available (for example 0.1 second).
									Thus, the pulse width will be the minimum width (percent_time) plus the number of
									increments (delta_time/ 255). The smallest time that can be used with the RIO
									controller is 0.1 second. An example stroke at mid position is: 0.1 second
									(percent_time) + 128 x 0.1 (255/0.5 - 50 percent position) = 12.9 seconds. The period
									would equal the percent_time plus the delta_time (for example 0.1 seconds) + 255 x
									0.1 seconds = 25.6 seconds.
