Step 2. MAC Address Setup

Access Point
WE70-AP
To attach PLC connected to WE70-CL to network, a client (slave) needs a setup as follows. Specifying a
MAC address (Ethernet address) of PLC's Ethernet unit to Terminal MAC Address field for WE70-CL.
Caution Only 1 model connected to WE70-CL can be registered to Terminal MAC Address.If more than one model is connected,
it is necessary for PLC2 to issue a ping to PLC1 provided as an FINS command.
Ex. For Ethernet unit CJ1W-ETN21, Ethernet address is indicated at the right side.

Step 3. PLC Setup

To connect a PLC to a network, Ethernet unit's IP address must be configured.A unique IP address must be
allocated for each communication node,using either of the followings:
1. Specifying with a default IP address
A rotary SW in the Ethernet unit can specify a FINS node address (1 to 254), which is used as a
host block of the IP address. A FINS node address and an IP address to be specified for an
Ethernet unit have the following relationship:
192.168.250.FINS_Node_Address
That is, specifying a node number 10 to a network of 192.168.250.* sets an IP address of
192.168.250.10 by default.
2. Specifying by Unit Setup of CX-Programmer
From I/O Table window of online CX-Programmer, select an Ethernet unit and specify an IP
address from Unit Setup.
3. Specifying by CPU advanced function unit assignment DM area
Under a status of an IP address unconfigured for Unit Setup, specify an IP address to IP
Address Display/Setup Area of CPU advanced function unit assignment DM area.
By default, IP addresses of an access point and a client are:
Access Point (WE70-AP): 192.168.0.1
Client (WE70-CL): 192.168.0.254
