84 Operation Theory

Continuously Comparison with Trigger Output

To compare multiple data continuously, functions for building com-

parison tables are provided and are shown below:

HSL_M_build_comp_function(AxisNo, Start, End,

Interval)

HSL_M_build_comp_table(AxisNo, tableArray, Size)

HSL_M_set_auto_compare(AxisNo, SelectSource)

The first function builds a comparison list using start and end

points and constant intervals. The second function builds on an

arbitrary comparison table (data array). The third function is a

source comparing selection function. Users can check current val-

ues used for comparison using the function

HSL_M_check_compare_data():

Example:

Using the continuous position comparison function.

Figure 4-39: Continuously Comparison with Trigger Output

In this application, the table is controlled by the motion command,

and the CCD Camera is controlled by the position comparison out-
