The state where the condition is satisfied is retained until the user program is stopped or the event point is reset.
When the condition on the event point is satisfied, no action will be taken even if the condition is satisfied again.
If you want the action to be taken again, reset the event point so that the state transits to that where no condition
is satisfied.
When the user program is stopped, the states of all the event points transit to that where no condition is satisfied.
When an event point must be in the state where its condition is satisfied or not (when [No occurrence of] is
selected) as the satisfaction condition of another event point, this event point is called the arm event.
An event point can reset the tested states of conditions of other event points or itself by satisfying the condition.
This event point is called a reset event.
A reset event resets event points regardless of their states where the condition is satisfied or not (e.g., resetting
the pass count).
Select an event point from the [Event] combo box. To set an arm event on the selected event point, select [Is
Armed By] and check the box corresponding to each event. The [No occurrence of] check box is used to set a
condition that the arm event is in the state where its condition is not satisfied.
To set a reset event on the selected event point, select [Is Reset By] and check the box corresponding to each
event.
At the bottom of the screen is a diagram showing the current sequencing of the events (figure 5.26). The S input
sets (arms) an event and the R input resets it. The legend ~S indicates the event is set (armed) by the non-
occurrence of the input events.
Figure 5.26 is an example that Ch1 is the arm event for Ch2, Ch3, and Ch4. Ch3 is the arm event for Ch4. Ch2
and Ch4 are the reset events for Ch1 and Ch2, respectively.
To satisfy the condition of the event point having an arm event, the arm event must be in the state where the
condition is satisfied or not (when [No occurrence of] is selected). When multiple arm events exist on one event
point, one of the arm events must be in the state where the condition is satisfied or not (when [No occurrence of]
selected) to satisfy the condition of the event point.
As the condition of the arm event on one event point, either of the states where the condition is satisfied or not
should be set.
To reset an event point with a reset event, the condition of the reset event must be satisfied. While the condition
of the reset point is satisfied, no event point is reset even if the condition of the reset event is satisfied again.
When multiple reset events exist on one event point, the event point is reset when the condition of one of reset
events is satisfied.
