The number of event setpoints for each static object type
is specified via the
NOTE
The device clears all event buffers and links the default set
of static points to each event object type every time you
change the number of points for any of the objects.
To define setpoints for selected static points:
1. Check the "Ext" box if you wish to use the extended
point list.
2. Select a parameter group and then a desired
parameter for each event point.
3. For AI and BC points, select a relation and an
operating threshold or a deadband to be used for
detecting events. All thresholds are specified in
primary units. The following relations are available:
• Delta – a new event is generated when the absolute value of
the difference between the last reported point value and its
current value exceeds the specified deadband value;
• More than (over) - a new event is generated when the point
value rises over the specified threshold, and then when it
returns below the threshold minus a predefined return
hysteresis – applicable for AI objects;
• Less than (under) - a new event is generated when the point
value drops below the specified threshold, and then when it
returns above the threshold plus a predefined return
hysteresis – applicable for AI objects.
