CAUSE
The background of the image is not
refreshed.
Tag minimum and maximum are not
setup.
No minimum and maximum setup on
the data tags displayed in the viewer.
Location of the drivers unknown.
The operating system is unable to
find the driver or the installation
failed.
The option selected during the
upgrade was Modify instead of
Repair.
SOLUTION
Change the primitive Fill Format to
Solid color.
Add the system variable dispcount
in the background of the image to
force the refresh.
Check the tag's minimum and maxi-
mum values. These are used by both
primitives for minimum and maxi-
mum.
Check that all displayed tags in the
trend viewer have a Minimum and a
Maximum setup.
The drivers are located under Graco
Gateway 2.0\Device installation
folder. For example C:\Program
Files\Graco Gateway\Device.
In your operating system device man-
ager, check if the Graco Gateway is
present. If so, uninstall that device.
Follow the USB installation guide.
Launch the upgrade again and
choose Repair when prompted.
