Product Line

Environment
Configuration Software for Windows
Resolution
To set up the Machine Expert Gateway to be able to connect to devices with a specific subnet mask (in this example, '255.255.255.0'), follow these steps below:
- Run Notepad.exe as Administrator in Windows
- From Notepad, open the file "Gateway.cfg" in the SoMachine Gateway folder (default location: "C:\Program Files (x86)\Schneider Electric\EcoStruxure Machine Expert\Tools\Gateway")
(For SoMachine, the location is "C:\Program Files (x86)\Schneider Electric\SoMachine Software\Tools\Gateway\") - Under the [CmpBlkDrvUdp] section, add the line "itf.0.networkmask=255.255.255.0" (or replace 255.255.255.0 with a subnet mask of your choice)
- Save the Gateway.cfg
- Restart the Gateway Service from the green "=S=" logo icon on the right side of the Windows taskbar (or restart the Windows Service called 'CoDeSys Gateway V3')
