An update rate indicated in this manner overrides the default rate.
Manual Updates
If a manual link has been specified between an application and the CX-Server project, the information contained
within the application is not updated until the appropriate action is taken by the user.
Within Microsoft Excel, this would be achieved by highlighting the cell containing the link and selecting
Calculate Now
from the
Options
menu to update the displayed contents of the cell.
Defining Update Intervals
The Update Interval dialog allows a default update rate (in seconds) to be assigned to new data requests. Use
the following procedure to define an update interval:
1, 2, 3…
1. Select
the
Update Interval
option from the
DDE Manager
menu.
2.
Enter the required update rate (in seconds) in the
Interval
field; this has a maximum
value of 65535.
3. Select
the
OK
pushbutton to save the setting and close the dialog.
The new rate applies to those points which are activated after this rate has been set. Currently active points are
not affected.
Note
The default time interval for the DDE Manager tool (when it is initially installed) is
set to 15 seconds.
