2.2  Basic Settings
Own Node Settings
Set the IP address and communication data code of the Ethernet-equipped module.
*1 This setting is not available for the CPU module (built-in Ethernet port part).
Item Description Setting range
Parameter Setting Method Set the own station settings by parameters. Parameter Editor (fixed)
IP Address IP Address Set the IP address of the own station.
Ensure that the Ethernet-equipped module on the own station and the external 
device to be communicated with have the same class and subnet address. 
Consult with the network manager for the IP address setting.
When using the IP address in a redundant system, use as the system A IP 
address.

•Blank
• 0.0.0.1 to 223.255.255.254
(Default: Blank)
Subnet Mask Set the subnet mask pattern of the default gateway when setting the IP address 
of the default gateway and communicating with an external device on another 
network via a router. All the devices on a subnetwork must have the same 
subnet mask. This setting is not required when communicating in single network.
•Blank
• 0.0.0.1 to 255.255.255.255
(Default: Blank)
Default Gateway Set the IP address of the default gateway (the device which the own node 
passes through to access a device of another network).
Set the value that satisfies the following conditions.
• The IP address class is any of A, B, and C.
• The subnet address of the default gateway is the same as that of the 
Ethernet-equipped module on the own station.
• The host address bits are not all "0" or all "1".

• 0.0.0.1 to 223.255.255.254
(Default: Blank)

specifying the network number and station number)
• Communications using the SLMP (when specifying the target station with its 
network number and station number)

(Default: Use IP Address)
Network Number Enter the network number of the own station when selecting "Not Use IP 
Address" in "Setting Method".
1 to 239
(Default: 1)
Station No. Enter the station number of the own station when selecting "Not Use IP Address" 
in "Setting Method".

Enable/Disable Online Change Select whether to enable external devices to write data in SLMP 
communications while the CPU module is in RUN state. ( Page 243 Enable/
Disable Online Change)
• Disable All (SLMP)

(Default: Disable All (SLMP))
Communication Data Code Select the communication data code used for communications. • Binary
• ASCII
(Default: Binary)
Opening Method Select how to open a connection when using UDP/IP communications or 
Passive open of TCP/IP communications.
• When "Do Not Open by Program" is selected, a connection is open when the 
system received the Active request. Program for open/close processing is not 
required.
• When "Open by Program" is selected, the open/close processing are 
performed by a program. The module cannot communicate when the CPU 
module is in STOP state.
