Defining Update Intervals; Special Data Types - Omron CX-PROGRAMMER V9 - REV 12-2009 Operation Manual

PART 3: CX-Server Runtime
CHAPTER 5 – DDE Manager Tool
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...
The new rate applies to those points which are activated after this rate has been set. Currently active points are
not affected.

Special Data Types

The LREAL data type is now supported by the Points Editor for the CS1H-H and CJ1H-H PLCs. Support for the
LREAL type is as the IEEE754 Double precision (1.7E +308/-307) as defined by Microsoft®.
