Prior to using this communications interface, you must perform the following steps:

1. Install an Ethernet card in your computer.

2. Configure the minimum TCP/IP Communications for your computer, including assignment of a name and TCP/IP address for the computer.

3. Assign a TCP/IP address for each Mitsubishi Melsec-A programmable controller. If you are on a company-wide or standardized network, you should obtain your TCP/IP addresses from your network administrator

4. For each programmable controller communicating with CIMPLICITY software via Ethernet, assign a Socket port number for the connection. If you are on a company-wide or standardized network, you should obtain your Ethernet port number from your network or system administrator.

5. Configure the TCP/IP address for each Mitsubishi Melsec-A programmable controller on your computer.

In the CIMPLICITY supported Windows operating system, use the

\Windows\System32\drivers\etc\hosts

file for the configuration.

In the hosts file, add one line for each Mitsubishi Melsec-A programmable controller in the following format:

<IP_address> <PLC_name> <PLC_alias>

Note that each field is separated by at least one space. For example, if the IP address configured for the Mitsubishi Melsec-A programmable controller is 1.2.3.4 and the name for the PLC is "MELSEC", the line in the hosts file for this controller will be:

1.2.3.4 MELSEC melsec

6. On each programmable controller, configure the host address for the programmable controller as well as assign the Internet address and socket port number to a connection. Please refer to the required documents above for assistance in developing the needed ladder logic

7. Use the Mitsubishi TCP/IP test program to check the configuration of your network without starting a CIMPLICITY project.
