Remote Access to Control Systems
Access Your Control Systems Remotely
Today, reliable, secure Internet connection allows for remote access to control systems, industrial computers, web cameras and other devices in industry as well as other areas. If any of these devices fails, remote access enables a technician to troubleshoot the problem faster, as they do not have to travel to the site. Using their PC, they simply connect to the remote access router linked to that device, via a secure VPN tunnel.
Remote access allows you to:
Remote access considerably reduces the time necessary for reprogramming or repairs in the case of a machine breakdown. In the IoT age, it is no longer a convenience but a standard that saves time and money.
Today, many manufacturers automatically equip their machines with Ewon routers already in production, which enables them to provide faster servicing and technical support over the Internet. Nevertheless, Ewon routers boast many other capabilities. Let us share them with you.
Getting started with remote access

Why does FOXON rely on Ewon?
We have been in the remote access business since 2009, when we signed a distribution agreement with the Belgian company Ewon. At that time, there were several remote access system providers on the market. However, Ewon beat each of them in many respects. Since the official start of our cooperation with Ewon, we have witnessed many situations where the Ewon remote access solution delivered by us helped the customer troubleshoot a problem and put their production line back into operation.
1. Machine builders
Companies that manufacture single-purpose machines often sell them worldwide. These machines come with warranties and the manufacturers provide servicing for them. Travelling to customer sites to repair or maintain them is time-consuming and expensive. That is why many producers equip their machine control systems with remote access routers, enabling them to provide their services remotely.
2. System integrators
It is also those who interconnect and integrate various systems that can benefit from remote access. It allows them to modify and back up PLC programs remotely and thus save a great deal of money. In other words, they can help their customers from anywhere, anytime.
3. The maintenance staff of a production plant
Maintenance staff are in charge of preventive checks on machines and fast troubleshooting in the case of a production line breakdown. It is, nevertheless, impossible for a control system programmer to be at several sites at the same time. But, with remote access, they can connect to the machines from anywhere, via the Internet.
How to Go About It
In our experience, currently the best industrial remote access solution is Ewon routers. They offer easy installation, highly secure data transfer and the very robust Talk2M cloud platform.
You can choose between two Ewon router types. The Ewon COSY 131 is a simple model without any advanced functionalities. You only have to connect it to the Internet, the device that you want to access remotely and the Talk2M service – and your remote access solution is ready for you to use.
Apart from the capabilities of the COSY 131, the more sophisticated model – the Ewon FLEXY 205 – features the ability to collect technological and production data from control systems. It also allows you to work with that data, for example by setting email alarms. As the FLEXY is only slightly more expensive than the COSY, before you make your choice, think twice – you may well need to work with data in the future.
Another option is Teltonika routers. Not only do they support remote access, they allow you, for example, to interconnect two networks. They are suitable for applications where you need to connect tens or hundreds of remote and/or moving devices to your VPN network.
One of the main advantages of Teltonika routers is their high reliability. In particular, dual SIM router types offer redundant Internet connection. In addition, you can take advantage of the automatic restart capability, which restores your connection in the event of a connection failure.
