Troubleshooting Connection Problems

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.
• The required termination is present in the network.
• The internal power supply is switched on (if required).
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.
