In the example below, Mode 4 is the selected function that compares the
value
of analog input A01 to a constant
value (N) of 2.50. Status coil G01 turns ON when A01 is not less than constant 2.50.
Example 2: Timer/Counter present value Compare
The Comparator instruction can be used to compare Timer, Counter, or other function values to a constant value or
each other. In this example below, Mode 5 is the selected function that compares the value of Counter (C01) with the value
of Timer (T01). Status coil G01 tu
r
ns ON if present value of C01 isn’t less than present value of T01.
