eWON’s Free+ service of Talk2M is an Internet connectivity tool designed to address the growing need for broadband and wireless access in the automation world for remote maintenance and access to remote equipment. The key added value of Talk2M is full integration of IT security standards by enabling Internet tunneling between the user and the remote machine without requiring any changes to IT network security settings at either end. This major breakthrough facilitates easy deployment while hiding the complexity of the IT network infrastructure.
On request or permanently, depending on the integrated modem of the eWON unit, a secure VPN connection to the Talk2M web server is established using a UDP or TCP HTTPS port, thereby passing through the firewall and proxy server. At the other end, the user establishes a secure VPN connection to the Talk2M web server. The Talk2M server acts as a relay to interconnect the two VPN tunnels. The information exchanged during the communication session is encrypted (128-bit SSL), and only authenticated users can connect to the eWON unit.
This service also allows an easy and seamless upgrade to the ‘Pro’ version, with no local change in eWON configuration nor any disruption in eWON connections. A completely renewed PC client (eCatcher 3) interfaces both Free+ and Pro services. Clearly, remote machines or installations worldwide are just one click away and at broadband speed.
The Free+ service replaces the old Talk2M Free, which met great success among machine builders and system integrators. It complements the historical and pioneering Talk2M Free offering with several added-value features.
