A Blue Icon on bottom with a Green
Icon on Top 
means the Script Engine has
failed. This will affect Global Scripts and Email (including
Alarm Emails and Pager Notification). It is recommended to Stop and
Start the SCADA node.
A Blue Icon on Top with a Green Icon
on bottom 
means the Thin Client Interface has
failed. This will affect users of Pocket PCs, PDAs and other
Thin Client users. It is recommended to Stop and Start the SCADA
node.
Both Screens Blue 
means both the Thin Client Interface
and Script Engine have Failed or have not started. It
is common for both to be Blue when the SCADA Node is first
started.
A Yellow Icon 
means the SCADA node Kernel is starting or
failed to start (datacore.exe has failed to start).
