10.7 Troubleshooting
If no device is found when the scan check is done:
1. The field wiring - make sure that the electrical segment connections are correct, as defined
by the specific user manual supplied with the field device and segment coupler / power
supply.
2. Make sure that an unstable voltage supply from the segment power supply and / or electrical
interference, does not cause interference with the operation of the loop power supply.
Some bridging devices / LAS implementations use an optimization where some address ranges
a
r
e not scanned. This can result in an individual device not being found.
After the address is set, it may take some time for the device and the Link Active Scheduler (LAS)
to
synchronize information: this includes address, identity, and protocol timing information.
10.8 Device Focus View
This view shows the specific information of the device:
• PD tag.
• Device Id.
• Block List with Target / Actual Mode.
On entering ‘Device Focus view’, the software loads the Blocks of the target field device and
m
a
kes them available for parameterization.

Select the Scan icon to show device scan view again. Refer to Section 10-1
1.
Select the desired block with a single key tap to open the Navigation Tree for the block. Refer to
Section 10.9.
10.9 The Navigation Menu Tree
This is the overview of the fully loaded block of the device (this is not the entire field device, only
one part of it). This overview shows all the menus available, as controlled by the configured
access level. Many field devices have additional menus that become visible when an access right
is enabled, or other parameters set. The navigation tree shows nested menus with a ‘+’ to the left
of the description. A tap of this symbol opens up the view to the lower level. This view can be
