IQM-233 Operating Manual

Sif142SetPower (long Output, double Power)

Sets the control voltage value in Manual mode. If an output was in Auto mode,
turns off PID control and places the output in Manual mode.

Output . . . . . . . . . . . . . . . . . . . . Specifies the output, from 0 to 17.

Power. . . . . . . . . . . . . . . . . . . . . Between 0.0 and 1.0, representing 0 to 100%

of Full Scale.

Sif142MapSensors (long SensLoop(0 to 23))

An array that associates each sensor (0 to 23) with an output (0 to 17) for PID
control. An output value of -1 for a sensor causes the sensor to continue to
monitor deposition, but have no effect on output control.

SensLoop (). . . . . . . . . . . . . . . . Array (0 to 23) of sensor to output

assignments (0 to 17).

Sif142GetReadings (double SensorArray(0 to 23, 0 to 2),
double OutputArray (0 to 17))

Fills two arrays with measurement data. In the second dimension of the
SensorArray the elements are Rate (Å/s), Thickness (Å), and Frequency (Hz).
Negative frequency values indicate a sensor error. OutputArray is output
power, 0 to 1.

If a 0 is returned, there are no new readings available. A non-zero value
indicates there is new data, with the returned value indicating the number of
readings in the buffer. The buffer is 10 readings long. To flush the buffer, keep
reading until there is no new data.

Sif142GetPower (double PowerArray(0 to 17))

Fills the array with the current output powers. Unlike Sif142GetReadings
OutputArray, the value is an instantaneous unbuffered value.

SqmSimulate (long Type)

Sets the type of card to simulate.

Type . . . . . . . . . . . . . . . . . . . . . . Type of board to emulate
