Step 3. Checking PC-PLC Communication

Execute the Ping command to PLC from PC connected to AP-1 and verify its response.
• Set CL-1's SSID as the same one as that of an access point to communicate. (In this
example those of AP-1 and AP-2)
• When performance of smart roaming switching time is required, combine WE70-AP and WE70-CL.
• For mobile operation of CL-1, make sure that CL-1 should not go into an area where radio
wave cannot reach from neither AP1 and AP-2.
Caution
• When smart roaming is being valid, and if CL-1's received electric field strength levels
from AP-1 and AP-2 are not very much different, roaming may not be available or may
take a long time.
• Repeating is available for 6 segments.
• As larger number of segments decreases throughput, take precautions for an application
that requires high speed. Always perform testing before actual operation.
CL-1
(5) From CL-1 Setup screen "Information" menu, "Wireless Information",
"BSSID", verify that BSSID should be AP-2 value.
CL-1
(6) Check if communication is available between PC and PLC.Test the
roaming in the opposite direction and verify that access points should be
switched from AP-2 to AP-1 and that communication should be available
between PC and PLC.
(1) Execute a ping command from your PC at command prompt.
Example:Ping 192.168.0.10 (Partner's IP address)
C:¥>ping 192.168.0.10
Pinging 192.168.0.10 with 32 bytes of data:
Reply from 192.168.0.10: bytes=32 time<1ms TTL=250
* If no response is returned, follow the steps below:
• Execute "arp -d" command.
• Verify if security settings are the same.
Chapter 4. Advanced Setup
If the client has different SSID and/or encryp-
tion setup from the access point, "Communi-
cation Unavailable" is displayed.
