OPC UA concepts

The FairCom Edge OPC UA service can connect to and interact with OPC UA devices

Abstract

The FairCom Edge OPC UA service can connect to and interact with OPC UA devices

The FairCom Edge OPC UA service can connect to and interact with OPC UA devices. This service is included in the FairCom jsonAction API.

OPC UA is a client/server unified architecture that supports OPC UA devices only. A typical OPC UA system includes a hardware device that acts as a server that is connected to sensors or other equipment.

OPC variables are identified by a namespace and a name.

The FairCom Edge OPC UA service can capture OPC UA data from OPC UA devices for forwarding to other non-OPC UA systems. It can be enabled and disabled within the FairCom Edge server.

Note

You must enable the OPC UA service before requesting data from an OPC UA server.
