OMRON
CHAPTER 3 – Points
Release 2.0
Page 33
In order to access a CX-Supervisor point value via OLE2 Automation, it must be given OLE Read or
OLE Write access. The scope of the access can be defined by checking the appropriate setting in the
OLE Access.
The point value which is stored to disk may be Volatile or Non-volatile by selecting or deselecting
the
Non-Volatile
check-box. A Non-volatile point ensures the preservation of the point’s value at
regular intervals. If power is lost, or CX-Supervisor is shut down for any reason, then when the
application is restarted the point is initialised to the last saved value. These values are saved in a
project file with .NVP extension. To prevent unexpected operation, this file is automatically deleted if
further point changes are made in the Developer. In this case points revert to their Default value.
Select the
Validate Point is Within Specified Range
check-box. This option is only available for
Input or I/O points of type Integer or Real. When checked, an error message is displayed in the error
log if the data passed to CX-Supervisor is outside of the specified Minimum and Maximum range.
Click the
OK
pushbutton
to accept the advanced settings, or the
Cancel
pushbutton
to abort the
operation.
Amending an Existing Point
To modify an existing point, highlight the point from the points list and click the
Modify
Point
button from the toolbar.
This results in the View Point dialog being displayed as shown below, a dialog based on the Add
Point dialog:
