channel to determine whether or not a responding HART device is

If a channel does not have a device attached, the DTM periodically 
queries the channel in order to detect a newly connected device.
4. Click Next to exit.
IMPORTANT
In order to use the Diagnostic function, the DTM must be online,

is offline when the Diagnostic dialogue is opened. The online 
status of the DTM is displayed at the bottom of the Diagnostics 
dialogue.
IMPORTANT
No device DTMs have to be configured in order to use the 
Diagnostics function.
