The Range 0 Tab Page is used to set a comparison range for the counter
value. The range has a lower limit (LL0) and an upper limit (UL0). The digital
output can be controlled according to the counter value in respect to this
range. Range 0 controls the digital output 0 (OUT0).
Click the Range 0 Tab in the Edit Unit Parameters Window. The Range 0 Tab
Page will be displayed.
■ Operation
The output will be controlled according to the relationship between the
counter value and the range settings as follows:
• If UL0 > LL0, digital output 0 will be ON when LL0 ≤ Counter value ≤ UL0,
and will be OFF otherwise.
• If UL0 < LL0, digital output 0 will be OFF when UL0 ≤ Counter value ≤
LL0, and will be ON otherwise.
• If UL0 = LL0, digital output 0 will be ON when LL0 = Counter value = UL0,
and will be OFF otherwise.
The following figures illustrate the first two cases.
