11.6.3 Confirmation of communications based on the ping
command
(1) Confirmation from the CNC side
Use the ping command from the CNC side. For the embedded Ethernet, see
Subsection 11.4.5(1), “Ping command transmission.” For the fast Ethernet
board/fast data server, see Subsection 11.5.5(1), “Ping command
transmission”.
When there is no response from the destination unit, a hardware connection
and/or software setting may be faulty. Check the connection and settings
for errors.
(This function is not supported by the Ethernet board/data server of
10BASE–T type.)
(2) Confirmation from the personal computer
An example below is used for explanation.
Check method:
At the command prompt, enter ping NC–IP–address. If a response is
returned, a connection has been established.
The example below assumes that the IP address on the CNC side is
192.168.1.1.
1) If a response is returned (normal)
C:¥ >Ping 192.168.1.1
Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1:bytes=32 time<10ms TIL=128
Reply from 192.168.1.1:bytes=32 time<10ms TIL=128
Reply from 192.168.1.1:bytes=32 time<10ms TIL=128
C:¥>
2) If no response is returned (abnormal)
C:¥ >Ping 192.168.1.1
Pinging 192.168.1.1 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
C:¥>
If the ping command is specified with the –t option, the transmission of ping
packets continues until you press Ctrl+C.
