Input the following at the host computer prompt ($):
$
ping IP_address(host_name)
The destination is specified by its IP address or host name. If the host name is
used, the host name must be defined in file /etc/hosts.
Note The PING command is not supported by some host computers.
These examples show sending the PING command to the node at IP address
130.25.36.8. The "$" on the example screen represents the host computer
prompt. User inputs are underlined. Comments are placed after semicolons.

Refer to operating system documentation for your host computer for details
about using the host computer's PING command.
The internode test sends data to and from specified nodes and uses the
responses to check the network.
If a normal response is returned for an internode test, it means that the set-
tings for the FL-net Unit are correct.
The test parameters are set and the test is started and stopped by writing the
required data to the CPU Bus Unit Area (in the CIO Area) of the PLC used to
start the internode test. These setting are made using a Programming Device,
such as a Programming Console.
1. Write the test parameters into PLC memory. The test parameters are de-
scribed following this procedure.
2. Turn ON the Internode Test Start Bit allocated to the FL-net Unit in the CPU
Bus Unit Area. The Internode Test Start Bit is described following the test
parameters. This will begin the internode test.
