Troubleshooting
5.3.1.3
No Communication via TP/FT-10
This error can either be caused by the configuration of the LONW ORKS network or
by the ICS itself. For diagnosis please proceed as follows:
Check wiring and termination of the LONW ORKS network (see [12]) and supply of the
ICS.
Check if the device is located in an area of strong alternating magnetic fields.
Magnetic fields may cause interferences in the TP/FT-10 transceiver.
5.3.1.4
No Communication via IP-852
For diagnosis please proceed with the following steps:

5.3.1.5
Check the Ethernet wiring. If the LNK LED does not light up the physical
connection to the Ethernet network has been interrupted.
Check the IP settings of the device, the IP-852 channel and the availability
per ping command. Make sure that an IP address is only assigned once.
Check per ping command (command line PC tool) that the IP-852
configuration server can be accessed in the network.
Check the settings of the IP-852 configuration server.
No Network Variable Updates via IP-852 or TP/FT-10 Available
For error diagnosis and repair please proceed as follows:
Check the CEA-709 communication (see 5.3.1.3 and 5.3.1.4).
Check that the device is properly commissioned (use a network management tool
or NLUtil). which means in the state "configured online". Unlike Neuron based
nodes for LONW ORKS networks the service LED of the ICS does not visualize this
state! This characteristic is due to the fact that the ICS can include several ICS-709
nodes but is provided with only one service LED.
Determine if extended network management commands are used or have been
used. Make sure that the network management processes strictly with or without
extended network management commands (see also 5.1.2).
5.3.1.6
No Connection to the Web Server
For diagnosis please proceed as follows:
Check the Ethernet wiring. If the LNK LED does not light up the physical connection
to the Ethernet network has been interrupted.
Check IP address and netmask of the device. Make sure that the IP address is only
assigned once. Check the connection per ping command.
