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] < The result of the evaluation is TRUE, when the
variable selected in parameter 13-10 Comparator
Operand is smaller than the fixed value in
parameter 13-12 Comparator Value. The result is
FALSE, if the variable selected in
parameter 13-10 Comparator Operand is greater
than the fixed value in
parameter 13-12 Comparator Value.
[1] = (equal) The result of the evaluation is TRUE, when the
variable selected in parameter 13-10 Comparator
Operand is approximately equal to the fixed
value in parameter 13-12 Comparator Value.
[2] > Inverse logic of option < [0].

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).
