18.2 Override Command
If a CcnOutput object is a discrete point type it can be forced on (value of 1, active text defined by
the one’s value of the discreteTextOffset text pair). It can be forced off (value of 0, inactive text
defined by the zero’s value of the discreteTextOffset text pair).
The Ccn Driver manages two force levels (level 4 is used for commands, level 8 is used for links)
and the auto level (0). The command level force is the highest priority available from the Ccn
Driver.
If CcnOutput object is a discrete point type, the command will open a combo box which will have
Force On (Discrete on Text) and Force Off (Discrete off Text) options. Selecting either of these
commands will result in a Force command being issued. Following successful completion of the
Force command, the value field(s) of the Point Entry and CcnOutput object will reflect the new
value. The Entry from the PointListManager will change to lavender color.
A point value Force command can be performed by right clicking on the CcnObject and select
Actions->Override command.
To-do this, the CcnObject should be added to station database.
We can override a value from PointListManager or we can do the same from wire sheet view. .
Observation: Some of the points are not overriding properly. The same behavior is observed in
R2.
18.3 Auto Command
The CcnOutput objects can be autoed. The auto level command can remove the force level
command.
Following successful completion of the Auto command, the value field(s) of the Point Entry and
CcnOutput object will reflect a new value.
A point value Force command can be performed by right clicking on the CcnObject and select
Actions->Auto command.
Todo this, the CcnObject should be added to station database.
We can override a value from PointListManager or we can do the same from wire sheet view.
