7.4.4.2 Comparator Mode 1 ~ 7 – Analog Comparisons
The comparator will turn on its output contacts when the comparison between the input
signs is true. The 7 comparison modes permit the following relations between input signs:
In the example below we selected mode 4 of the function to compare the analog input
A01 value to the constant value 2.5. If it is enabled, the comparison function G03 will turn
on its output contacts when A02 is less than 2.5.
This other example shows the use of counters and timers as comparison parameters.
Using mode 5, values of C01 and T01 will be compared turning on output contacts G06
when the counting of C01 is higher than or equal to current T01 time.
