7.4.2 Troubleshooting
• If no device is found when performing scan check:
Field wiring. Verify electrical segment connections are
in accordance with the specific manual supplied with
the field device and segment coupler / power supply.
The loop is not suffering from interference due to an
unstable voltage supply from the segment power
supply and / or electrical interference.
• Some bridging devices / LAS implementations provide an
optimization whereby some address ranges are not
scanned. This may result in individual device not being
found.
• After setting address, it may take some time for the device
and the Link Active Scheduler (LAS) to synchronise
information including address, identity and protocol timing
information.
