13-11 Comparator Operator
Option: Function:
Select the operator to be used in
the comparison. This is an array
parameter containing comparator
operators 0–5.
[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] <.
[5] TRUE longer
than..
[6] FALSE longer
than..
[7] TRUE shorter
than..

3.13.3 RS Flip Flops
The reset/set flip flops hold the signal until set/reset.
Illustration 3.55 Reset/Set Flip Flops
2 parameters are used, and the output can be used in the
logic rules and as events.
Illustration 3.56 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.
