How to take advantage of Cosy+ to connect to your PLC?



The role of the Cosy+ is to establish a secure VPN connection between your machine and yourself, wherever you are and whenever you want. The connection happens through Talk2M, a highly secured cloud-based remote connectivity service dedicated to industrial solutions.

Thanks to Talk2M, engineers can remotely access to their PLC, HMI or other devices inside the machine, for maintenance or monitoring, from anywhere in the world and from any device, even from a smartphone. Cosy+ allows to avoid unnecessary on-site visits, and therefore to save huge amounts of time and money while providing a major long term competitive advantage.
