8.2 General Troubleshooting
When troubleshooting a WirelessHART network, the first step is to check the power and an-
tenna connection. Once that has been established, check that the gateway is powered on by
looking at ST LED.
Refer Table 15 to identify various problems and possible solutions.
Table 15: Troubleshooting procedures
Problem Solution
Unable to open Webserver 1. Ensure power is applied to AWIN GW120.
2. Ensure cable is connected between PC and AWIN GW120. If so, LINK
LED is ON.
3. Verify network settings of PC match network settings of AWIN GW120.
They should be on same subnet. Confirm IP addresses of LAN inter-
face. If IP address is unknown, the AWIN GW120 can be hard to reset.
This will result in factory default configuration, and all previous config-
uration will be lost. See Section Basic Features of AWIN GW120 Gate-
way for details.
4. The LAN Link and Duplex selection in the AWIN GW120 should match
the settings of the connected wired network. Select Auto if in doubt.
5. If the device still retains the error state, then try soft or hard reset.
WirelessHART
field devices take a long
time to connect to the net-
work or WirelessHART field
devices are not communi-
cating to the AWIN GW120
gateway
1 Log into the AWIN GW120 and verify that Active Advertising is on. By
default, Active Advertising is ON for 60 minutes. This feature can be re-
activated for adding new devices to the network more quickly.
2 Verify that the field devices are powered up and also verify the correct
Network ID and Join Key are programmed into the devices. Make sure
to use the proper decimal and hexadecimal representations of the Net-
work ID and Join Key, as they can vary between vendors.
3 Make sure that the devices are within the communication range of the
gateway or another WirelessHART device configured in the same net-
work.
4
Make sure that there is no competing WirelessHART gateway with
same Network ID and Join Key running in parallel in the target cover-
age area.
Error LED illuminates after
bootup
Log into web manager, if possible, to check the status of the AWIN
GW12 0. If it states on Home page: “Error Retrieving AP Mote Data From
Network Manager”, then wait for at least two minutes to let the gateway
clear the error itself. If it persists afterwards, then reboot the gateway. It
can be done through the reboot option in the maintenance menu. If it is
not possible then power cycle the gateway.
Error LED illuminates If the gateway is subjected to excessive ethernet frames (or data/broad-
cast storm) then it can result in reduced performance and in extreme
cases may result in freeze of communication in the gateway.
In such event, normal operation can be resumed by removing the cause of
the “data /broadcast storm” and physically restarting the device by power
cycling.
