(2) Ethernet setting
The settings items for the network No. and station
No. do not exist at the Built-in Ethernet port
Motion Controller CPU side. However, these
virtual values must be set on the GOT side.
Therefore, set the network No. and station No. on
the GOT side. Set the network No. that is not

(1) When using the Command Prompt of Windows
Execute a Ping command at the Command Prompt of
Windows
.
(a) When normal communication
C:\>Ping 192.168.3.39
Reply from 192.168.3.2: bytes=32 time
<10ms TTL=32
(b) When abnormal communication
C:\>Ping 192.168.3.39
Request timed out.
(2) When abnormal communication
At abnormal communication, check the followings and
execute the Ping command again.
