Mitsubishi Control Setup

The Mitsubishi NC takes its network settings as parameters, not as a settings screen. Set #1925 to #1928, then reboot the control — the changes do not take effect until you do.

Connect to: the Ethernet port on the control · Port: 683, fixed · Licence required: none

Step 1: Access Network Settings​

  1. Press SYSTEM button on control panel
  2. Navigate to Network or Ethernet settings
  3. Depending on control version, may be under:
    • SYSTEM → Network
    • Parameter → Ethernet
    • Setup → Communication

Step 2: Set IP Address​

Before establishing a network connection, verify and configure the following CNC parameters:

Mitsubishi Network Parameters

Parameter #NamePurpose
1925EthernetEnables Ethernet connection
1926Global IP AddressIP address of the CNC that indicates the addressing of the NC
1927Global Subnet MaskGrouping of the IP network
1928Global GatewayIP address of the forwarding host (i.e., the router)

Configuration Example:

  • Parameter 1925 (Ethernet): Set to 1 (enabled)
  • Parameter 1926 (IP Address): Enter static IP (e.g., 192.168.1.100)
  • Parameter 1927 (Subnet Mask): Usually 255.255.255.0
  • Parameter 1928 (Gateway): Your network gateway IP (e.g., 192.168.1.1)
  • Port: Uses port 683 (standard for Mitsubishi)

Important: If the network connection doesn't work after setting these parameters, reboot the control for the changes to take effect.

Step 3: Enable Communication​

  • Enable Ethernet communication if disabled
  • Set communication protocol to allow external access
  • No additional protocol licenses typically required

Step 4: Verify Connection​

  1. Note the IP address you configured
  2. From a computer on the same network, ping the machine: 
    ping 192.168.1.100
  3. Should receive replies confirming network connectivity
