70 ID_PROFILE_STATE - This is the run state of the profile.
71 ID_PROFILE_STEP - This is the step in the profile which is currently
being run.
119 ID_UI_PROFILE_STARTRUN - This is the restarting mode of the
profile.
9.7 Single "Puff" Solenoid Control Variable
73 ID_PULSE - This variable allows opening the inlet or exhaust for the
specified duration for one pulse period. After one pulse duration, the
variable is returned to a value of 0.
9.8 Pulse Mode Variables
81 ID_PULSE_PERIOD - This controls the rate of the pulse while pulse
mode is active. The value represents how many passes through the
control algorithm (25ms per pass) before sending a pulse to one of the
solenoids.
82 ID_PULSE_WIDTH - This controls how long the solenoid is held open
while pulse mode is active.
allowed system fluctuations (or noise) so too small a number will not
open the solenoid valve.
83 ID_PULSE_DEADBAND - This is the error from the setpoint allowed
for the pulse function to stop pulsing. This value is in counts read up
from the sensor. One count of error is .03% and typically this number
is in the range of 0-3.
84 ID_PULSE_ENABLE - This turns the pulse function ON(1) or OFF(0).

0 => STOP
1 => START
2 => RUN
0 => Restart profile at the beginning.
1 => Resume profile at current profile step.
0x08fa => Inlet full open.
0x0800 => Both valves closed.
0x0706 => Exhaust full open.

The "units" variables are used by
supplied software to display the pressure
range units (i.e. psi.).
The scale minimum and scale maximum
variables are used by supplied software to
show minimum and maximum ranges.
