It describes errors that may occur during system operation and provides the causes of errors, corrective measures. You can
check whether there are some problems with the XGB embedded Fenet and the details through the below procedures.
Please note that we do not provide after-sales service for discretionary repair or disassembly based on the Quality Policy.
Problem Corrective Measures
In case LINK/ACT LED
flickers or is not turned on
after connecting to network.
1. Check whether the cables clicked inserted.
2. Check whether the XG-PD parameters are already downloaded.
☞
In case XG-PD’s communication basic parameters are not
downloaded, you cannot set up Full Duplex /Half Duplex communication.
In case the LINK/ACT,
SPEED LED are still turned
Off, although you download
parameters after supplying
power and connecting
network
Module defect is suspected so follow-up service may be required.
In case Read/Write Data do
not work during dedicated
services
1. Check the communication speed(Auto/10/100M-TX) .
It should have the same communication speed with the opposing
device to be communicated.
☞
In case the device with Auto Negotiation and the device with manual
speed are mixed in the network, the former recognizes the latter as Half
Duplex(standard specification of IEC 802.3u)
2. Check the IP address settings. The IP should be valid in the network.
☞
In case the set IP addresses are overlapped in the network or invalid
IP exists, communication is impossible.
3. Check the driver(dedicated, Modbus TCP/IP) settings.
☞
You should apply the same protocols with the opposing device.
4. Check whether the opposing device’s IP is registered in the host table.
☞
When the opposing device’s IP address is not registered under host
table Enable, communication does not work.
5. Check the MAC Address
☞
In case the MAC Address is abnormal, communication does not
work.
