The Industrial Router for Secure Remote Access to your Control Equipment

The Cosy range of gateway routers offers the possibility to visualize and troubleshoot control systems (PLCs, HMIs, cameras...)**, which considerably reduces support costs and improves the availability of equipment.

Access and administration of Cosy routers is done from a Cloud VPN service - TalK2M - offered free with the purchase of the routers. (see Talk2M)

The latest addition to the range, the Cosy+ provides a major innovation by integrating security into the very heart of the electronic components ('Hardware Root of Trust'), further enhancing the possibilities of remote access to the most critical sites.

Cosy routers provide several advantages for flexible and secure industrial remote maintenance:

  • Choice of connectivity mode (wired Ethernet, WiFi, Cellular)
  • LAN segregation to limit remote users' access to part of the equipment,
  • Local authorization for remote connectivity by means of an external key switch
  • Digital output to signal an active remote connection to field operators.


All areas regarding remote maintenance of machine manufacturers, OEMs, integrators, service companies, etc. for:

  • Monitoring the operation of equipment remotely
  • Assist your customers in the use of your systems
  • Diagnose malfunctions
  • Access HMIs to perform actions on equipment
  • Correct or modify the programs of your PLCs
