Q 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.
Q 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.
Note: Copy Protection must be installed for this function.
Q Which OPC Servers have been tested with CX-Supervisor?
