To connect the CPU module to a personal computer, use the following methods: (Page 470 Transfer setup)
■Connection through an RS-232C communication port
Connect the CPU module that is hooked up with an FX5-232-BD or FX5-232ADP with an RS-232C cable.
■Connection through an Ethernet port
• Connection via a hub
Connect the CPU module via a hub to a personal computer on the same local network. Note that IP address of the CPU
module must be specified. Also the personal computer should have the same network address as the CPU module.
Only local area network can be used for connections. Connections via the Internet are not allowed.
• Direct connection
One-to-one direct connection with an Ethernet cable is possible. This method requires no hub. Note that IP address of the
CPU module need not be specified with this method.
• Do not directly connect to a personal computer via LAN line. Load imposed on the LAN line adversely affect
communications of other devices.
• Do not configure the direct connection setting when using one-to-one connection via a hub between the CPU module and a
• If the following conditions are met, the direct connection communication may be disabled. If the communication is disabled,
review the settings of the CPU module and personal computer.
When all the bits of the CPU module-side IP address that correspond to 0 part of the personal computer-side subnet mask are
ON or OFF:
CPU module-side IP address: 18.104.22.168
Personal computer-side IP address: 22.214.171.124
Personal computer-side subnet mask: 255.255.0.0
In the CPU module IP address bits, if the bits corresponding to the host address of the class of the personal computer IP
address are all ON or all OFF:
Personal computer IP address: 192.168.0.1 ← 192.x.x.x., class C and the host address is the fourth octet.
Personal computer subnet mask: 255.0.0.0
CPU module IP address: 126.96.36.199 ← each bit turns on because of the fourth octet is 255
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 portion including "0" as shown below.
• Class A: 255.0.0.0
• Class B: 255.255.0.0
• Class C: 255.255.255.0
