4.Configure the following in "PC Settings"
c_plc_0271

setting	Setting contents
Computer IP address	192.168.0.1
Computer port number	9600

5.Set the following in "Unit side settings"
c_plc_0272

setting	Setting contents
Unit IP Address	192.168.0.100
Unit Port Number	9600

6.Select "Ping Test" to check if the ping goes through normally.
If you see a message like "Ping test is success～", the test was successful.

7.Select the protocol in "Communication Details"

8.Perform a connection test to check the connection
c_plc_0274

If a message such as "Connection OK" is displayed, the connection is confirmed to be OK.

When testing the connection and setting up the folder, do not forget to specify the node (network settings).

•Source/Destination Network Number: Please specify the network number. Specifying 000 will indicate your own network.

•The source/destination node sets the node. If you specify 999, the last part of the IP address will be the node.

If you connect using the settings in this example, you can also connect by specifying "000,1,000,100".
