We have recently completed a project using the eWON Flexy to connect a PLC to a cloud based database.
The eWON Flexy is an industrial VPN router that connects a PLC to the internet via the Talk2M service. Talk2M does all the hard work of linking the PLC to the internet and managing the remote access. The connection to the PLC can be via serial or Ethernet with the connection to the internet via fibre/copper or wireless over wi-fi or a GSM modem. The eWON has expansion slots that allow for a range of modules that provide the various different connection options.
The eWON Flexy supports the BASIC and JAVA programming languages and can also host web pages to provide a low cost HMI viewable from a standard web browser. For the cloud database application we used BASIC script for the eWON to read data from the PLC and JAVA to write the data, via Talk2M, to the cloud based database.
If you have an application where you want to remotely connect to a PLC so your ‘machine can talk’ then please don’t hesitate to contact us.
