13-11 Comparator Operator
Array [6]
Option: Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
[0] < Select [0] < for the result of the evaluation to
be TRUE, when the variable selected in
13-10 Comparator Operand is smaller than the
fixed value in 13-12 Comparator Value. The
result will be FALSE, if the variable selected in
13-10 Comparator Operand is greater than the
fixed value in 13-12 Comparator Value.
[1] ≈ (equal) Select [1] ≈ for the result of the evaluation to
*
be TRUE, when the variable selected in
13-10 Comparator Operand is approximately
equal to the fixed value in 13-12 Comparator
Value.
[2] > Select [2] > for the inverse logic of option <
[0].

Illustration 3.52
The two operators can be selected from a long list. As a
special case, the same digital input can be used as both
Set and Reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input as start/stop (example given
with DI32 but is not a requirement).
