12 Template Displays and Container
Points
A template display is a custom display that is used to represent a unit of
equipment containing several points of one or more fixed types. A template
display is functionally equivalent to the supplied Point Detail displays for status,
analog, and accumulator points.
To use a template display, you first define a container point for the unit of
equipment. The container point operates as a custom point type for a unit of
equipment, such as a compressor or a door, that contains several points of one or
more fixed types. For example, you might have a number of compressors that all
contain:
– An analog point to monitor the pressure
– A status point to control the motor
– An accumulator point to monitor hours run
“Compressor” container points tie these sets of points together so that each set
can be managed as a single point.
For information about how to define container points, see the Quick Builder
online help. For information about building custom displays, see the Display
Building Guide.
Engineering Guidelines for Container Points
Container points behave like fixed type points, with the following exceptions:
• Alarms raised on a contained point are not promoted to its container point.
This means that a container point never goes into alarm, and therefore
never appears on the Station Alarms display.
To ensure that operators can quickly recognize an alarm on a container
point, you might:
– Include the Point ID of the container point in the description of all the
points it contains.
– Configure the Associated Display for all contained points as the
template display specified for the container point.
• You cannot attach an algorithm to a container point.
