4.9.1 $EVENT User Defined Input/Output (continued)
Parameter Values
<event group> This parameter defines the group number of a group
of events and the order they are executed. Events
are grouped together to control execution sequence.
A group number has to have at least one input event
and one output event. Multiple input events within a
group number would be treated as a logical AND
condition. Multiple output events within a group
number would be executed individually in a
sequential manner.
Valid values for group number are: 1 thru 99.
<event type> This parameter defines the type of event: Input or
Output. An Input event can be defined as:
Transition, Occurrence, or Input. The output event is
executed when input event conditions are met.
Value Type of event Description
0
Transition
Trigger
A transition Trigger is defined as an input condition,
defined by <event category>, whose value was
previously <parm1> or less is now greater than
<parm1> and less than <parm2> or was greater or
equal to <parm2> is now less than <parm2> but
greater than <parm1>.
The output event would be executed when an input
<event category> requirements are satisfied or
transition to the value set by <parm1> and
<parm2> when they are equal. <parm1> should be
the min value and <parm2> should be the max
value.
Example 1:
Parm1 Parm2
0
Max
Figure 1. An output event will be executed when the
value of an input event exceeds <Parm1>
(previously it was <Parm1> or less) or decreases to
a value less than <Parm2> (previously it was
<Parm2> or greater).
Example 2:
Parm1 = Parm2 = 0
