Setting up a Secure VPN Connection between a PC and LOGO! 8

  • Entry
  • Associated product(s)
You can use the LOGO! CMR as OpenVPN server in pre-shared key mode and access the CMR securely via mobile network connection.

The LOGO! controller is an intelligent logic module from Siemens for small automation projects, for example, in building automation. The entire LOGO! 8 product family is equipped with Ethernet interfaces and thus offers new options of communication. LOGO! modules can communicate with each other via Ethernet and the Ethernet standard makes remote access possible, for example, for remote maintenance.

The task is to establish a secure connection between a service PC and LOGO! CMR via Internet and the mobile wireless network.

You can use the LOGO! CMR module (Communication Module Radio) as OpenVPN server in pre-shared key mode. This function extension makes it possible for you to remotely access the web interface of LOGO! CMR and LOGO! BM and, for example, to install the LOGO! BM program via a secure mobile wireless network.
