1. First, connect PLC with Internet. Please attend to indicated LED. In normal situation, Link LED always light
and RUN LED(CMXXE) are blinking like below :
& & & & .CM25E

2. Executing the Ethernet configure software then scan the IP address of FBs Ethernet modules.
3. I assumed that 192.168.2.100 as master(Client Mode) and 192.168.2.110 as slave(Server Mode).
Below are detail setting content.
