(2) Precautions: Connection not regarded as direct connection
Connection between the Ethernet adapter module and GX Works2 through a switching hub is not regarded as
direct connection. Do not configure the settings for direct connection.
(3) Precautions: Conditions under which communication is not possible through
direct connection
(a) When two or more Ethernet ports are enabled in the network setting of the personal
computer
Communication is not possible in direct connection. Correct the setting on the personal computer so that only
one Ethernet port will be enabled for direct connection and the others will be disabled.
(b) IP address condition 1 of the Ethernet adapter module
In the IP address bits of the Ethernet adapter module, if all of the bits corresponding to subnet mask 0 of the
personal computer are on or off, communication may not possible through direct connection. Correct the
settings of the Ethernet adapter module and/or personal computer.
• IP address of the Ethernet adapter module: 64.64.255.255
• IP address of the personal computer: 64.64.1.1
• Subnet mask for the personal computer: 255.255.0.0
(c) IP address condition 2 of the Ethernet adapter module
In the IP address bits of the Ethernet adapter module, if all of the bits corresponding to the host address in each
class of the personal computer IP address are on or off, communication may not possible through direct
connection. Correct the settings of the Ethernet adapter module and/or personal computer.
• IP address of the Ethernet adapter module: 64.64.255.255
• IP address of the personal computer: 192.168.0.1
• Subnet mask for the personal computer: 255.0.0.0
Remark
● The IP address for each class is as follows:
Class A: 0.x.x.x to 127.x.x.x, Class B: 128.x.x.x to 191.x.x.x, Class C: 192.x.x.x to 223.x.x.x
●
The host address for each class is the part of 0 as shown below.
Class A: 255. 0. 0. 0, Class B: 255.255. 0, Class C: 255.255.255. 0
