Cosy Award

The Ewon COSY 131 is a unique industrial LAN/WAN router designed for remote access to PLC control systems, HMI panels and webCams via cable Internet, WiFi and mobile networks. As the unique Talk2M cloud service enables fast communication with the remote Ewon router, you can be performing several activities at the same time – you can be remotely programming a PLC while backing up data from an operator panel and monitoring a production line through a web camera. Peripherals are connected to the router via Ethernet ports or an additional Ethernet switch.

The COSY is suitable for system integrators and OEM manufacturers. Its affordable price allows them to automatically install it in control cabinets and thus have access to all their devices on customer sites, monitoring their operation, modifying programs, performing diagnostics, etc.

The COSY creates a remote connection via the Talk2M service, which enables you to remotely connect to your devices through a secure VPN tunnel from any computer, mobile or tablet connected to the Internet.

Typical Ewon COSY Application

  • Remote access to devices for single-purpose machine builders
  • Remote access to production lines for system integrators
  • Remote access to devices and production lines for maintenance personnel

Main Ewon COSY Features

  • 1× WAN port for connecting the router to the Internet
  • 3× LAN port for connecting local Ethernet devices (you can create more ports by connecting an Ethernet switch)
  • 2× DI digital input and 1x DO digital output for monitoring and controlling external signals
  • 4× router models available depending on how the router connects to the Internet
  • Very easy router setup
  • Easy configuration of connecting to Ethernet devices behind the router (PLUG'N ROUTE functionality)
  • 24 VDC power supply
  • DIN mount

Ewon Cosy 131 Models Compared


How the Ewon COSY Works

In the picture below, you can see typical deployment of the Ewon Cosy 131 on the factory floor. In the green, bottom-left field, you can see an Ewon router connected to several devices via Ethernet and USB (PLC 1, PLC 2, a camera and an HMI panel). This router communicates with local network programs (e.g. an OPC server) via the Factory LAN local network. The Ewon is connected to the Internet through port 443 (HTTPS) or port 1194 (UDP) and then to the Ewon TALK2M cloud service, which facilitates communication between the router and a remote user via a secure VPN network.

The router supports all devices with an Ethernet port, even if they are connected to it through a switch. If you want to connect the SIMATIC S7-300/400 PLC to the router and the PLC does not have a communication module inserted or does not support it, you can use the ACCON NetLink PRO Compact Ethernet adapter. This adapter converts MPI / PROFIBUS to Ethernet. Then you can connect the PLC to one of the router's LAN ports.

How to Set up Your Cosy 131 Easily?

The Cosy 131 is configured through its web interface. This interface includes the Quick Launch Wizard, which guides your through the settings and informs you whether a particular setting has been saved or not. The router settings enable you to set the router's date and IP addresses, assign WAN port functionality to one of the router's ports and connect the router to the Internet and the Talk2M service.


In the last step of the Wizard, you can configure the router's digital inputs. The router features 2 digital inputs, which are usually configured in the following way:

  1. The input controls the router's Internet connection (the customer can enable and disable Internet connection any time they want and thus control the OEM manufacturer's access to the device behind the router).

  2. The input is used to monitor the door of a control cabinet (i.e. whether it has been opened).

  3. By connecting a PLC's status output, the customer can be alerted whenever the PLC is in STOP mode.


Multifunctional SD Card

The SD card allows you to easily configure you Ewons. You can use it to perform a firmware upgrade and to create or restore a system backup. Last but not least, you can auto-register into Talk2M thanks to the Global Registration Key (GRK). Inserting the SD card containing the GRK will automatically link the Ewon to your account! You just need to insert the SD card containing the appropriate file in the Ewon. It will automatically process the file. Then remove the SD card from the Ewon, which will start a reboot. It is as simple as that. Please note that you have to upgrade to the firmware v11 or higher to take advantage of this feature. Your settings backup file can be saved to the SD card or a USB stick.




The Ewon COSY's title page provides a summary with all the essential information about the router's operation on a single page. You will find there such information as Internet connection status, IP address information, Connected to Talk2M since, the router as gateway setting, firmware version, etc.

To be able to connect to the Ewon COSY via the Talk2M service, you need the eCatcher application and a Talk2M account.

In the window below, you can see a secure connection between a computer and the Ewon COSY 131, via the Talk2M. Under the router's name, there is a list of all Ethernet devices connected to the router. By clicking on any of the blue links, you will be directed to the website of the respective device. The device can also be accessed through third-party software (e.g. STEP7, TIA Portal, WinCC, etc.).


Cosy vs. Flexy Comparison

Ewon COSY 131 vs. Ewon FLEXY 205

Talk2M Cloud

The Talk2M is a cloud service for the field of industrial automation. It enables you to securely connect to remote Ewon routers, perform remote access operations and collect data from control systems connected to the routers. Using the Talk2M, you can remotely program and troubleshoot your PLCs as if you were on-site.

The Talk2M utilises the technology of VPN (Virtual Private Network) and tunnelling. This cloud service facilitates communication between users and their machines in such a way that data can be transferred seamlessly.

The Talk2M is available in two variations – the Talk2M FREE+ and the Talk2M PRO. The Talk2M FREE+ is free of charge, but supports only a limited amount of data transferred and only a single VPN connection at a time. The PRO version, which is a paid version, supports multiple connections at a time. It also enables you to grant various user permissions and increase the limit on data transferred if needed. Below you can learn more about the two versions and decide which would be more suitable for you.


We recommend upgrading the firmware of your Ewons to the latest version. 

The way you upgrade an Ewon's firmware depends on the type of Ewon and its current firmware version. To learn more, please read the article How to Upgrade Your Ewon's Firmware: A Full Summary.

When upgrading firmware, use the latest version of the eBuddy software.
