13-11 Comparator Operator
Array [6]
Option: Function:
[0] < Select [0] < for the result of the
evaluation to be true, when the
variable selected in
parameter 13-10 Comparator
Operand is smaller than the xed
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 xed
value in
parameter 13-12 Comparator Value.
[1] ≈ (equal) Select [1] ≈ for the result of the
evaluation to be true, when the
variable selected in
parameter 13-10 Comparator
Operand is approximately equal to
the xed value in
parameter 13-12 Comparator Value.
[2] > Select [2] > for the inverse logic of
option [0] <.
[5] TRUE longer
than..
[6] FALSE longer
than..
[7] TRUE shorter
than..
[8] FALSE shorter
than..

Illustration 3.38 Flip Flop Outputs
The 2 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 (for example, DI32) as start/
stop.
