Force Hierarchy

There is a hierarchy in CCN with regards to forcing a point.
Programs and devices write a force at different priority levels. A
higher level (smaller number, 1 being the highest) will override a
lower level force. The Scrolling Marquee uses a Control Force at
level 7. The Navigator writes a Service Force which is level 3.
System Pilots and Touch Pilots write Supervisor Forces at level 4.
Network programs can be set to write different level priority forces.

Generic Status Display Table

The GENERIC points table allows the service/installer the ability
to create a custom table in which up to 20 points from the 5 CCN
categories (Points, Config, Service−Config, Set Point, and
Maintenance) may be collected and displayed.

In the Service−Config table section, there is a table named
“GENERICS.” This table contains placeholders for up to 20 CCN
point names and allows the user to decide which points are
displayed in the GENERIC points sub−table under the status
display table. Each one of these placeholders allows the input of an
8−character ASCII string. Using a CCN interface, enter the Edit
mode for the Service−Config table “GENERICS” and enter the
CCN name for each point to be displayed in the custom points
table in the order they will be displayed. When done entering point
names, download the table to the rooftop unit control.

IMPORTANT: The computer system software (ComfortVIEW

t,

Service Tool, etc.) that is used to interact with CCN controls,
always saves a template of items it considers as static (e.g., limits,
units, forcibility, 24−character text strings, and point names) after
the software uploads the tables from a control. Thereafter, the
software is only concerned with run time data like value and
hardware/force status. With this in mind, it is important that
anytime a change is made to the Service−Config table
“GENERICS” (which in turn changes the points contained in the
GENERIC point table), that a complete new upload be performed.
This requires that any previous table database be completely
removed first. Failure to do this will not allow the user to display
the new points that have been created and the CCN interface will
have a different table database than the unit control.
