OPC is actually a standard communication protocol for acquisition, based on an open model structure, it allows to push data from any industrial devices or according on their native protocol and publish it in a standard language which every single application in automation field must connect through it.

vNode is an Industrial IoT Gateway designed to gather data from your facility such as PLCs, controllers, sensors, OPC DA Servers, etc and deliver it to IT, cloud or industrial environments including OPC UA Clients.

 vNode Software can act as an OPC DA Client which it allows to communicate and take data from any OPC DA Server from a different vendor.

On the other hand, vNode can behave as an OPC UA Server providing information to any OPC UA Clients, HMI, SCADAS, Mobile developments

Both solutions make easier and functional the integration of different applications.

How does it do it?

OPC DA Client: vNode collects the data from any OPC Real-time Data access server, over COM/DCOM communication based on Microsoft technology. Using OPC Enumerator it can look over the host or network for OPC DA Server prog ID and start and engage to it.

OPC UA Server: remember that vNode can collect data from any data sources, but what about to export that data? vNode OPC UA Server, using standard OPC UA endpoint sends the data to an OPC UA Client that an on Linux, windows, android IOS or any other environment.

Which type of solutions you can make with vNode OPC DA Client and OPC UA Server?

  • OPC DA to OPC UA
  • Modbus to OPC UA
  • Siemens to OPC UA
  • Allen Bradley to OPC UA
  • REST API to OPC UA
  • MQTT to OPC UA
  • OPC DA to SQL
  • OPC DA to MQTT
  • OPC DA to REST
  • OPC DA to SAP
  • OPC DA to PI
  • OPC DA to MONGO

Paradigma of use 

Peter Thompson works for a system integrator company on industrial automation field, his end client, a manufacturing enterprise, need to migrate their SCADA system up to a brand new web environment in which they could manage, control and monitor all their process. The challenge for Peter is that the new web system only allows OPC UA communication, and based on the original customer architecture, all their industrial communication network based on PLCs, it’s a mix of protocols, including, Siemens, Allen Bradley, and OPC DA.

Thompson, though that he could convert those protocols up to OPC UA, but he didn’t know how to do it.

While he was looking on the internet, he found vNode Automation platform which is a basically an IoT Gateway for an industry that collects data from any data source and pushes it in different protocols, including OPC Unified Architecture. He made some contact with that company and found that they also can give him support and advice on his implementation, while they are also OPC UA trainers.

After a call, Peter achieved pulling data from one of the bunch of data sources his customer had, and vNode provide to him the URL endpoint for transfer the data over OPC UA  standards…

The rest is history…
