REMARK

The following example illustrates how to confirm the completion of the initial

processing by issuing the PING command to the local station’s Ethernet module

from an external device connected on the same Ethernet (DOS/V personal computer

Ethernet module).

(In the example, the confirmation is made between devices whose IP address class

and net ID are identical.)

[Designation]

ping IP address

[Program example]

IP address of the Ethernet module: 192.168.1.201

C:\>ping 192.168.1.201 Execute the ping command

Pinging 192.168.1.201 with 32 bytes of data:

Reply from 192.168.1.201: bytes=32 time=2ms TTL=250

Reply from 192.168.1.201: bytes=32 time<1ms TTL=250

Ping statistics for 192.168.1.201:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)

Approximate round trip times in milli-seconds:

Minimum = 1ms, Maximum = 2ms, Average = 1ms

Check the following, then perform the PING test again.

• How the Ethernet module is mounted on the base unit.

• Status of the connection to the Ethernet.

• Contents of the parameters written to the PLC CPU.

• Operating status of the PLC CPU (whether any errors have occurred.)

• IP address of the target Ethernet module designated with the PING command.
