13-11 Comparator Operator

Array [6]

Option: Function:

mately equal to the fixed value in

13-12 Comparator Value.

[2] Greater Than (>) Select > [2] for the inverse logic of option

< [0].

13-12 Comparator Value

Array [6]

Range: Function:

0.0 * [-9999.0 -

9999.0 ]

Enter the ‘trigger level’ for the variable

that is monitored by this comparator. This

is an array parameter containing

comparator values 0 to 5.

3.9.4 13-2*Timers

Use the result (TRUE or FALSE) from timers directly to define

an event (see 13-51 SL Controller Event), or as boolean input in

a logic rule (see 13-40 Logic Rule Boolean 1, 13-42 Logic Rule

Boolean 2 or 13-44 Logic Rule Boolean 3). 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 [8]

Range: Function:

0.0 s* [0.0 -

3600.0 s]

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

(see par. 13-52 [29-31] and 13-52 [70-74] Start

timer X) and until the timer value has elapsed.

Array par. containing timers 0 to 7.

3.9.5 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 13-40 Logic Rule Boolean

1, 13-42 Logic Rule Boolean 2 and 13-44 Logic Rule Boolean 3.

Define the operators used to logically combine the selected

inputs in 13-41 Logic Rule Operator 1 and 13-43 Logic Rule

Operator 2.

Priority of calculation

The results of 13-40 Logic Rule Boolean 1, 13-41 Logic Rule

Operator 1 and 13-42 Logic Rule Boolean 2 are calculated first.

The outcome (TRUE / FALSE) of this calculation is combined

with the settings of 13-43 Logic Rule Operator 2 and

13-44 Logic Rule Boolean 3, yielding the final result (TRUE /

FALSE) of the logic rule.

13-40 Logic Rule Boolean 1

Array [6]

Option: Function:

[0] * False Enters the fixed value of FALSE in the

logic rule.

[1] True Enters the fixed value TRUE in the logic

rule.
