10-4-4 Checking IP Address Using PING Command

156
Did the completion code end nor-
mally?
Is the control data set properly?
Is an IP address set that has the
same HOST ID as a remote node?
Are you communicating with
nodes on another network in the
FINS address system?
The PING command can be used from a Windows computer to check the FL-
net device connections and IP address settings, without requiring the FL-net
Network Analyzer or other special Programming Device. An overview of oper-
ation using the PING function are provided in the following table.
Checking IP Use the PING command to check that IP connections are correct.

2) Enter the PING command, and execute the basic internode test
between the Link Unit and personal computer. Enter the PING com-
mand as either Ping[IP address] or Ping[Host name].
IP Address Example: Ping 192.168.250. 13
The following message will be displayed if the corresponding FL-net
device setting is correct.

Refer to 10-1 Troubleshooting with Indicators as
well as the 10-3 Error Log.
Correct the network address, node address and
unit address in the FINS address settings.
Use the IP address setting switches (rotary
switches at the back of the Unit) or the CX-FLnet
or FL-net Unit Support Software to correct the IP
address setting.
If you are using the IP address setting switches,
you must turn the PLC OFF and disconnect it
from the network to reset it.
If you are using the CX-FLnet or FL-net Unit
Support Software, restart the PLC after you
change the setting.
Check to see if the relay path (routing table) is
defined for FINS messages.
Use the CX-Integrator to create the correct rout-
ing table.
Please note that all CPU Bus Units and INNER
Boards will reset automatically if you use the
CX-Integrator to define the routing table.
