FC 300 Design Guide
Logic rule 2 [28] Use the result of logic rule 2 in
the logic rule.
Logic rule 3 [29] Use the result of logic rule 3 in
the logic rule.
Digital input DI18 [33] Use the value of DI18 in
the logic rule (High = TRUE).
Digital input DI19 [34] Use the value of DI19 in
the logic rule (High = TRUE).
Digital input DI27 [35] Use the value of DI27 in
the logic rule (High = TRUE).
Digital input DI29 [36] Use the value of DI29 in
the logic rule (High = TRUE).
Digital input DI32 [37] Use the value of DI32 in
the logic rule (High = TRUE).
Digital input DI33 [38] Use the value of DI33 in
the logic rule (High = TRUE).
13-11 Comparator Operator
Array [6]
Value:
<
≈
>
Function:
Select the operator to be used in the comparison.
Select < [0] for the result of the evaluation to be
TRUE, when the variable selected in par. 13-10 is
smaller than the fixed value in par. 13-12. The re-
sult will be FALSE, if the variable selected in par.
13-10 is greater than the fixed value in par.
13-12.
Select > [2] for the inverse logic of option < [0].
Select ≈ [1] for the result of the evaluation to be
TRUE, when the variable selected in par. 13-10 is
approximately equal to the fixed value in par.
13-12.
13-12 Comparator Value
Array [6]
Value:
-100000.000 - 100000.000
Function:
Enter the 'trigger level' for the variable that is
monitored by this comparator. This is an array
parameter containing comparator values 0 to 5.

13-2* Timers
This parameter group consists of timer parame-
ters.
Use the result (TRUE or FALSE) from timers di-
rectly to define an event (see par. 13-51), or as
boolean input in a logic rule (see par. 13-40,
13-42 or 13-44). A timer is only FALSE when star-
ted by an action (i.e. Start timer 1 [29]) until the
timer value entered in this parameter is elapsed.
Then it becomes TRUE again.
All parameters in this parameter group are array
parameters with index 0 to 2. Select index 0 to
program Timer 0, select index 1 to program Timer
1, and so on.
13-20 SL Controller Timer
Array [8]
Value:
0.00 - 3600.00 s
Function:
Enter the value to define the duration of the FALSE
output from the programmed timer. A timer is on-
ly FALSE if it is started by an action (i.e. Start
timer 1 [29]) and until the given timer value has
elapsed.
13-4* Logic Rules
Combine up to three boolean inputs (TRUE /
FALSE inputs) from timers, comparators, digital
inputs, status bits and events using the logical op-
erators AND, OR, and NOT. Select boolean inputs
for the calculation in par. 13-40, 13-42, and
13-44. Define the operators used to logically com-
bine the selected inputs in par. 13-41 and 13-43.
Priority of calculation
The results of par. 13-40, 13-41, and 13-42 are
calculated first. The outcome (TRUE / FALSE) of
this calculation is combined with the settings of
par. 13-43 and 13-44, yielding the final result
(TRUE / FALSE) of the logic rule.
