Appendix 4.2 How to Check an Error Through GX Developer
The status of the various settings for the Ethernet module can be checked using the GX
Developer functions.
The following shows how to check the status.
(1) Ethernet diagnostics (Refer to Appendix 4.2.1)
The module status of the Ethernet module, parameter settings, communication
status, error log and others can be checked using the Ethernet diagnostic function.
The following are the functions of the Ethernet diagnostics.
Ethernet diagnostics
Parameter status
Checks the stored parameters after
the initial processing for the Ethernet
module.
Error log
Checks the error stored
in the error log area.
Status of each connection
Checks the status of each connection
after the connection to the external device
is established with the open processing.
Status of each protocol
Checks the communication status of each
protocol supported by the Ethernet module.
LED status
Checks the on/off status of the LED on
the front of the Ethernet module.
Received e-mail information
Checks the information for received e-mail.
Send e-mail information
Checks the information for sent e-mail.
PING test
Checks the completion of the initial processing
with the issuance of the PING command.
Loopback test
Checks the completion of the initial processing
for the Ethernet module in a network to which the
loopback command is issued.
COM.ERR off
Turns off the [COM.ERR.] LED on the front
of the Ethernet module.
(2) System monitor (Refer to Appendix 4.2.2)
The module status of an Ethernet module can be checked from the system monitor.
(a) Module's detailed information
The function version and error code can be checked.
(b) H/W information
The LED on/off status, connection status and parameter status of an Ethernet
module can be checked.
(3) Buffer memory batch monitor
The buffer memory of an Ethernet module is monitored.
