Figure 2: SLC Event and Action
Events and actions are each numbered and linked in pairs (states), which means that when event [0] is fulfilled (attains the value TRUE),
action [0] is executed. After the 1st action is executed, the conditions of the next event are evaluated. If this event is evaluated as true,
then the corresponding action is executed. 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 only evaluates event [0] during each
scan interval. Only when event [0] is evaluated as true, the SLC executes action [0] and starts evaluating the next event. It is possible to
program 1–20 events and actions. When the last event/action has been executed, the sequence starts over again from event [0]/action
[0]. The following illustration shows an example with 4 event/actions:

Comparators
Comparators are used for comparing continuous variables (output frequency, output current, analog input, and so on) to fixed preset
values.
