You use the Process Analyst Properties dialog box
to configure the pen data connection. This allows you to define the
server, trend tag, and request mode for the selected pen.
Pen connection can be configured at run time by
Operators and Users that have the appropriate privileges.
To configure pen data connection:
Select the pen you want to
configure.
Click the Connection tab to display the connection property
controls.
For the Server data connection, a <localhost> connection is selected by default,
indicating that the Process Analyst will connect to the
CitectSCADA run time client
running on the same computer, and pass its requests through to the
client, which will pass them onto the server.
If you would like to connect a pen to a
different server, the drop-down menu to the right of the field
provides a list of the server connections that are currently
configured. If you would like to add a new connection to the list,
see Configuring Connection
Properties.
In the Trend tagfield, enter the trend tag for the pen. In a system
with more than one cluster, specify both the cluster and tag using
the format <cluster name.tag
name>. Omitting the cluster name will cause an error. If
the system has only one cluster configured, you can just enter the
tag name. The configured cluster will be assumed.
Select a Request
mode. The default is Average.
The request mode defines how multiple
samples are treated by the Process Analyst. Regardless of the
request mode used, the timestamp for a sample is always
averaged.
