(1) [Controller Setting] and [Ethernet] of GT
Designer3
For [Controller Setting] and [Ethernet] of GT
Designer3, refer to the following.
8.3.1 Setting communication interface
(Communication settings)
(2) Ethernet setting
When connecting Built-in Ethernet port QCPU or
LCPU to a GOT, the settings items for the network
No. and station No. do not exist at the PLC side.
However, these virtual values must be set on the
GOT side. Therefore, set the network No. and
station No.
Therefore, set the network No. and station No.
Set the network No. that is not existed on the
network system and any station No..
(3) Controller setting
(4) Ethernet setting
*1 Set the same value as that of GOT N/W No.
*2 Set a value different from that of GOT PLC No.
Checking communication state of Connecting
to 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 192.168.3.2: 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.
• 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
