The eWON principle

error: img1


  • You want to supervise, tele-service and analyse your PLCs, machines and facilities outside your country or EU?
  • You want to keep access to your machines despite of BREXIT, refugee discussion or other crises?
  • You want to prevent expansive travels, security checks on airports or long waiting times on borders?
  • You want to help your customer as soon as possible?

You can do that!

Here you will find the example, how you can realize remote supervision and control successfully:
Teleservice of Thames Water

AIONA Automation presents:

The newest teleservice and industrial data solutions of the specialist eWON.
EWON is the pioneer of teleservice-networks since 10 years and has offered the first remote access modems for PLCs in the year 2001. Every EWON Router contains free access to the biggest and most advanced industrial VPN server network of the world: Talk2M
This is the biggest industrial VPN network in the world. It is serviced 24/7 and has 2 redundant servers on every continent at the minimum.
Talk2M is the only VPN network with a special solution for China to guarantee a stable access, in defiance of the special conditions in this country (“Great Firewall”).
Security is probably the most important aspect of the Talk2M architecture. The two-factor authentication works with HTTPS bank standard and whole system is based on guidelines set forth by leading security standards like ISO27002, IEC 62443-2-4 and NIST Cyber security Framework 1.0.

Another important aspect is the comfortable configuration.
Just some mouse-clicks and a few minutes to configure your Modem with automatic wizards and connect to your machine.

You can register an unlimited number of eWON router on you Talk2M Free account. The single limitation is one concurrent connection.
So you can connect to one router with VPN at the same time.
Additional 3 users get access over the web portal M2Web to every Homepage (fe.: IP cameras, PLC configuration sites, Web- Visualisations,...) and VNC Server (like HMI, PC,....) in your machines network. That works with every browser- able device, like Smartphones, Tablets, and much more. The cost- free included Cloud solution DATA MAILBOX makes powerful Industry 4.0 and Internet of Things (IOT) applications possible.

EWON offers 2 series:
1.) COSY : The Basic Modems enable quick and simple Teleservice.
2.) FLEXY : The Professional Modems are worlds first flexible Teleservice solution and support additonal PLC access, Alarms, Archiving, Web Visualisation, and much more.


EWON Devices can be tethered fast and easy with 3G or WAN/DSL/WLAN to company networks. The Talk2M function connects to the EWON T2M-server independently via a save VPN connection. The connection setup uses HTTP and switches afterwards to HTTPS (mobile banking safety standard) working in the same way like a PC with Internet browser. The system can be used everywere, if a normal Internet access is possible.
No changes are necessary in the IT configuration, firewall or with the mobile radio provider. EWON operates the required servers and backup systems. A highly professional administration and support team provides a worldwide and permanent availability: 24 hours a day / 7 days a week.

3G Quadband (EDGE/UMTS/HSDPA/HSUPA) and WLAN or WAN for external DSL modems.
