Mitsubishi TCP/IP Communications Configuration Checklist

About this task

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

Procedure

  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.
