Troubleshooting
– Check the power supply (LED RUN must light green).
– Check for correct connection (RJ-45, see "Connecting to
Ethernet" on page 15).
– The TH LINK is preset to network operation with a DHCP
server (IP address for the TH LINK is assigned by the DHCP
server). If your network server does not support DHCP, you
need to set the IP address for the TH LINK yourself
(see "Connection in a network with manual IP address
assignment" on page 22).
– When a crossover cable is used between PC/notebook and
TH LINK, both devices must be in the same subnet.
TH LINK as Passive PROFIBUS station:
– Check for proper connection (see "Connecting the
PROFIBUS" on page 28) and switch at Settings >
TH SCOPE
> Measurement the baud rate on Automatic
detection .
TH LINK as Active/Passive PROFIBUS station:
– Check the PROFIBUS parameters for the used TH LINK (see
application software, not included in the scope of delivery).
Each station has its own station address, which can only be
assigned once in the network.
