 Ethernet device gateway address setting
Set the IP address of the Ethernet-equipped module connected to an Ethernet device in the gateway address of the Ethernet device used.
 IP address setting of the Ethernet-equipped module ( Page 46 Setting in the Ethernet-equipped module)
 Setting of the network number and station number of the RJ71EN71 or the RnENCPU (network part) connected to the Ethernet device
When the RJ71EN71 or the RnENCPU (network part) is set for the Ethernet-equipped module connected to the Ethernet device, set "Communications by
Network No./Station No." in the module parameter of the Ethernet to "Enable".
 IP packet transfer setting ( Page 46 Setting in the Ethernet-equipped module)
This setting is required for the IP packet to be passed between an Ethernet-equipped module and a master/local or remote head module.
 IP address setting of a master/local module (Page 46 Setting in the master station)
 Routing parameter setting
Set routing parameters in the following cases. ( Page 47 Routing parameter setting)
• When modules other than MELSEC iQ-R series exist in the communication path
• When an Ethernet device needs to be connected to a module that does not support routing parameters
• When the Ethernet device is a personal computer (only Ethernet devices having the route command, such
as Microsoft
gateway address is set in the default gateway, packets not related to the IP packet transfer are also
transmitted through the CPU module. Consequently, the service processing of the CPU module drops under
heavy load, causing other service processings to be slow or other problems. For the gateway address
setting of when an Ethernet device is connected to a module other than an Ethernet-equipped module, refer
to the manual for the module connected to the Ethernet device.
• After the setting is completed, execute the IP communication test to check for an error in the communication
path. ( Page 48 IP communication test)
