The eWON Cosy is an industrial VPN router designed to offer easy remote access across the Internet to machines and installations on customer sites or in the field. OEMs and system integrators can troubleshoot machines remotely without going on-site, which significantly reduces support costs and resources.
eWON offers three products for remote access to controllers, operator interfaces and sensing devices of all types, via LAN, Wi-Fi or cellular connection.
The Cosy router can be placed on a machine, and an outbound connection is made using commonly left open TCP port 443 or UDP port 1194. Cosy includes free Talk2M service from eWON.
Cosy communication is designed for easy setup with no firewall issues, which allows access only to the machine and not to the factory LAN, and VPN access can be controlled locally with an external key switch.
Cosy uses a fully secure SSL-based VPN tunnel. The information exchanged during the communication is encrypted (SSL-2048-bit keys), and only authenticated users can connect to the eWON. The gateway offers PLC support for RS-232, RS-485 and RS-422, and it is an MPI/Profibus-to-Ethernet solution, compliant with PLC manufacturers such as Rockwell Automation, Schneider Electric, Siemens, Omron and Mitsubishi.
