Q&A
What is PLC communication?
PLCs (Programmable Logic Controllers) need to communicate with their environment to control robots, drives, conveyor belts or other industrial equipment. This works well if the machinery communicates using the same communication standard as the PLC. But if it is a device from another manufacturer – some kind of protocol translator or gateway is needed.
How do you connect to a PLC remotely?
By using an Ewon remote gateway, you can connect to a PLC or machine anywhere in the world – for troubleshooting, maintenance or data extraction.
The gateway connects to the PLC using Ethernet or USB and can then establishes a secure connection to the Ewon cloud where users can access and extract information from the PLC.
Is it safe to connect to a PLC remotely?
You might think that connecting remotely to a PLC opens the door to attack vectors. However, this is not the case when you use a verified and secure outbound connection, such as that created by an Ewon VPN gateway, which has been verified and tested by independent sources. The advantages of not having to physically go on site to troubleshoot, repair or access a machine are also obvious. You can rest assured: Ewon's remote solutions are used by over 500,000 machines worldwide.
