For [Controller Setting] and [Ethernet] of GT
Designer3, refer to the following.
23.3.1 Setting communication interface
(Communication settings)
(2) Ethernet setting
The setting items for the network No. and station
No. do not exist on 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 a network No. that does not exist on the
network system.

Checking communication state of Built-in
Ethernet port CPU
(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 192.168.3.39: 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.
• Cable connecting condition
• Confirmation of switch and network parameter setting
• Operation state of PLC CPU (faulty or not)
• The IP address of Built-in Ethernet port CPU specified
in the Ping command
Setting (Use default value.)
