FC 300 Design Guide
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 [4]
Option:
<
*
≈
>
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
result 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 [4]
Range:
-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 3.
13-2* Timers
"
This parameter group consists of timer parameters.
Use the result (TRUE or FALSE) from timers
directly 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
started 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 [3]
Range:
0.00 - 3600.00 s
Function:
Enter the value to define the duration of the FALSE
output from the programmed timer. A timer is only
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 operators
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 combine 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.
