Additional Information
The ping command uses the ICMP protocol to send a response request to a device connected
through an Ethernet network and determines the time required to respond to that request.
If you properly receive a response from the destination device, the network connection and net-
work settings are correctly set.
1
Connect the Sensor Controller and a computer with an Ethernet cable.
Set the high-order digits of the computer IP address to the same values as the Sensor Control-
ler and the low-order one digit to a different value.
<IP Address Setting Example>
Sensor Controller
Computer
2
Open the Windows command prompt on the computer and perform the ping command.
At the > prompt, type ping, followed by a space and the Sensor Controller IP address, and then
press Enter.
Example:
C:\>ping 10.5.5.100
3
After a few seconds, Reply from followed by the IP address of the Sensor Controller (e.g.,
10.5.5.100) are displayed, it means that the Sensor Controller is connected to the Ethernet net-
work properly.
Example:
Reply from 10.5.5.100: byte=32
Time<1 ms TTL=128
If anything other than Reply from is displayed:
The Sensor Controller is not connected to the Ethernet network for some reason. Check the
following.
• Are the high-order three digits of the IP addresses for the computer and the Sensor Control-
ler the same?
• Is the Ethernet cable correctly connected?
4
Use the ping command to check the communication status of the PLC as well.
After you have confirmed the communication status as described above, transmit a measure-
ment command to the Sensor Controller in practice to check the communication operations as
the Vision Sensor.
