Display Unit Conversion
The 
LonPoint Analog Data
frame in the 
Monitoring NVs 
window displays points
associated with the control loop. In this example you will force a new format to be used to display
the simulated OA temperature. In typical installations, once the default format file is selected, an
application will work typically within this default format presentation. To force the US format to be
used when SI format is the default, follow these steps:
1. 
From WindowMaker, double-click the 
‘#.00’
string to the right of the 
OA Temperature:
label.
2. 
Click on the Analog, Value Display animation link to determine the tag used for the animation link.
3. 
Double-click the tag name in the Expression: field to open the tag edit dialog.
4. 
Modify the item to add the flag: 
-tSNVT_temp_f#US
as shown in figure 12.
5. 
Save changes and step out of the nested dialog boxes.

Using the InTouch DDE Link Wizards
The LNS DDE server supports copy/paste DDE link operations to speed the definition of I/O tags
targeting the LNS DDE server. InTouch includes two wizards to support DDE copy/paste link
operations. The following steps describe how to take advantage of this feature when defining I/O
tags.
1. 
Click on the Wizard icon in the WindowMaker tool bar (this icon is a small conical wizard’s hat on
the far left of the main drawing tool bar). Select the 
Value Displays 
category on the left. The
dialog shown in figure 13 opens.
