Illustration 33: Associated Action
Events and actions are each numbered and linked in pairs (states). This means that when event [0] is fullled (attains the value true),
action [0] is executed. After this, the conditions of event [1] are evaluated and if evaluated true, action [1] is executed, and so on.
Only 1 event is evaluated at any time. If an event is evaluated as false, nothing happens (in the SLC) during the current scan interval,
and no other events are evaluated. When the SLC starts, it evaluates event [0] (and only event [0]) each scan interval. Only when
event [0] is evaluated true, the SLC executes action [0] and starts evaluating event [1]. It is possible to program 1–20 events and
actions per sequence.
When the last event/action has been executed, the sequence starts over again from event [0]/action [0]. See Illustration 34 for an
example with 3 events/actions:

xed preset values.
