OPC UA concepts
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.
