00_Header
00_Header Display must be configured always as startup page and may not be
closed at any time. This page contains Visual Basic code for supervising the
communication to the controller(s). It is monitoring the HMI tag “ComERR”
and popup the screen “20_ComErr”.
The HMI Tag ComErr is generated by the ComErr Event which is monitoring
the Heartbeat tag for communication errors.
If you want to monitor several processors for a communication error,
additional tags and expressions must be added to the Visual Basic code in the
00_Header Display and the ComErr Event.
