Secure remote support
Our engineers reach the machine. They never reach your network.
Why it exists
Downtime is measured in shifts. A controls engineer who can log in within minutes is worth more than one who can be on site tomorrow.
We searched extensively and chose eWON as our VPN gateway, keeping network security as the top priority. It will not compromise your IT department's firewall policy.
The eWON industrial router is DIN rail mounted, runs on 24 VDC, fits inside the automation control panel, and talks to both Ethernet and serial devices. It makes an outbound connection over HTTPS or UDP to the Talk2M cloud broker, which completes an encrypted tunnel to an authorized engineer.
The security question
Will a remote user reach my network?
No. This is the objection every IT department raises, and the architecture answers it directly.
- The router segregates the WAN from the LAN machine subnet — the remote user only reaches devices connected to the eWON's own LAN
- Outbound only, over port 443 (HTTPS) or UDP 1194 — no inbound firewall exceptions, no open ports, no routing policy changes
- You keep local control: a key switch or HMI button on the eWON's digital input enables or disables the tunnel on site
- Two-factor authentication can be enforced on every Talk2M login
What it saves
Time, and the cost of a plane ticket.
- Quick access to help your on-site staff troubleshoot
- Remote modifications or additions to a system's HMI or PLC program
- Reduced production downtime through immediate diagnosis
- None of the cost and delay of travelling to your facility
Talk to an engineer, not a call center.
Every enquiry lands with the people who design, build and test the equipment in Glasgow, Kentucky.
