• Why do I get “Invalid Point” error?
If this occurs on startup of the developer, it can be due to a corrupt point
definition. Usually, editing the Point and pressing OK is enough to correct
the corruption. If there are too many points, select a large group and use
the 'Multiple Edit' function to assign some common attribute to them all
e.g. OLE Access is Read Only. This in effect edits each point, also
correcting the corruption.
If this error occurs in the Runtime is means the point has been deleted or
renamed but a script or animation is still using the Point. Run the Analyse
Application tool to highlight and fix References to non-existent points.
• How do I access “CX-Supervisor Local Points” from Omron
Graphical components?
Omron ActiveX Graphical components, like the Thumbwheel shipped with
CX-Supervisor or those shipped with CX-Server Lite and CX-Server OPC
(7 Segment, Display, Knob Toggle etc) can be placed on CX-Supervisor
pages and linked directly to CX-Supervisor points by selecting a data
source of "CX-Supervisor Local Points".
However, note that the default setting for points is to allow reading, but to
protect against writing from external sources like these controls. If this is
attempted you will get the following error message "OLE Point
<pointname> has no write access".
Note however, that as a low priority message the default project
configuration will not cause the error log to automatically open and you will
have to manually view the error log viewer.
To prevent this error and to allow write access change the 'OLE Access'
to 'Read/Write' on the Advanced Point Settings dialog box.
Note: Copy Protection must be installed for this function.
