2 PARAMETER SETTINGS
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".
•Blank
• 0.0.0.1 to 223.255.255.254
(Default: Blank)

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

(Default: Disable)
Setting Method Select the method for setting the network number and station number. (

• Not Use IP Address
(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".
1 to 120

Transient
Transmission Group
No.
*1
Set the transient transmission group number of the own station. 0 to 32
(Default: 0)
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)
• Enable All (SLMP)
(Default: Disable All (SLMP))
Communication Data Code Select the communication data code used for communications. • Binary
• ASCII

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
