Faults indicated by Fieldgate LEDs
14.2
Wired Communication Faults
Fieldgate error messages are displayed in plain text in the
Diagnosis
Chapter 9 "Diagnostics" on page 55.
The following table summarizes the more common problems which might occur during com-
missioning and operation of the WirelessHART Fieldgate SWG70.
LED indication
Problem/Remedy
1 Red LED is lit
• Hardware fault which makes normal operation of the
Fieldgate impossible.
– Send Fieldgate back for repair.
2 Red LED flashes
• Under certain conditions the LED flashes while the
Fieldgate application tries to eliminate the fault.
– If this indication persists, even after a reboot, send the
Fieldgate back for repair.
Problem
Cause/Remedy
1 The computer is not able to establish an
Ethernet connection to the Fieldgate although
the Fieldgate and the computer are connected
to the Ethernet.
• The Fieldgate is connected to the Ethernet with a standard
cable although a crossover connection is necessary (or vice
versa).
– Wire in accordance with the table in Chapter 5.3.
• The Ethernet parameters of the Fieldgate are incorrect.
– Check the Fieldgate's Ethernet parameters
• The Local Area Connection Properties of your PC are not
configured correctly.
– Configure the Local Area Connection according to the
instructions given (see Chapter 7.1).
• If you are parameterizing via the web interface: Maybe
your web browser uses proxies.
– Deactivate proxies in your browser.
• Firewall blocking communication.
– Configure firewall to allow communication through
ports 80, 443, 502 and 5094.
2 The computer is not able to establish a serial
connection to the Fieldgate or the signal is of
poor quality.
• The terminating resistor is not activated.
– If the RS-485 cable ends at the Fieldgate (Fieldgate is
last device), activate the terminating resistor via the DIP
switch inside the Fieldgate housing (see Chapter 8.4.4)
or via the DTM (see Chapter 6.1.3.).
• Check cabling.
