How does it work?



The Ewon Cosy establishes a secure VPN connection from the machine to anywhere in the world via Talk2M, a cloud-based remote connectivity solution.

The gateway seamlessly communicates on the local area network with the PLC and the HMI, and allows remote connection from a computer, tablet, or smartphone.

Ewon Cosy and Talk2M make connectivity easy, and don’t require the user to be an IT expert to take advantage of the time and cost saving.
