How do I change LAN1 IP settings on a cMT-SVRX which has Codesys activated?

Hi @donnedved25,

When a cMT-SVRX is equipped with a CODESYS license, the LAN 1 port will be assigned to CODESYS and the LAN 2 port will retrieve an IP via DHCP by default. To change the IP of LAN 1, you can use the following method:

  1. Connect your PC to the LAN 2 port and open the web server.

  2. Enable the Codesys “Gateway”:

  3. Connect to Codesys using the HMI’s “LAN 2” port and note this is the same port you use to download the HMI application:
    Note: The IP address of my LAN 2 port is shown below.

  4. Within the Codesys IDE, double-click “Device (Weintek Built-in CODESYS)”, enter the SVRX’s LAN 2 IP within the drop-down list under the device, and “Press ENTER to set active path…”:
    Note: You should see a green dot when everything is connected.
