3.25.4 LC-2# Timers
Use the result (true or false) from timers directly to define
an event (see parameter LC-51 Logic Controller Event), or as
boolean input in a logic rule (see parameter LC-40 Logic
Rule Boolean 1, parameter LC-42 Logic Rule Boolean 2, or
parameter LC-44 Logic Rule Boolean 3). A timer is only false
when started by an action (for example [29] Start timer 1)
until the timer value entered in this parameter has elapsed.
Then it becomes true again.
All parameters in this parameter group are array
parameters with index 0–2. Select index 0 to program
timer 0, select index 1 to program timer 1, and so on.
LC-20 Logic Controller Timer
Array [8]
Range:
0 [0 - 0] 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 (for example [29]
Start timer 1) and until the given timer value has
elapsed.
3.25.5 LC-4# Logic Rules
Combine up to 3 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 parameter LC-40 Logic
Rule Boolean 1, parameter LC-42 Logic Rule Boolean 2, and
parameter LC-44 Logic Rule Boolean 3. Define the operators
used to logically combine the selected inputs in

Function:
Enter the trigger level for the variable that
is monitored by this comparator. This is an
array parameter containing comparator
values 0–5.
Function:
parameter LC-41 Logic Rule Operator 1 and
parameter LC-43 Logic Rule Operator 2.
Illustration 3.76 Logic Rules
Priority of calculation
The results of parameter LC-40 Logic Rule Boolean 1,
parameter LC-41 Logic Rule Operator 1, and
parameter LC-42 Logic Rule Boolean 2 are calculated 1
outcome (true/false) of this calculation is combined with
the settings of parameter LC-43 Logic Rule Operator 2 and
parameter LC-44 Logic Rule Boolean 3, yielding the final
result (true/false) of the logic rule.
