EXTRA INFORMATION
Entering the Threshold data:
At present the threshold values have to be entered as a count between 0 and 255, (8bit word), e.g. on
a 0VDC to 120 VDC system:
COUNTS = (( VOLTAGE + 5 ) / 37) * 255
55 V would be represented by:
55/120 = 0.458.
0.458 * 255 = 117 counts
The maximum count that can be entered is 16535, however the ISaGRAF kernel will limit any variable
to 240.
