FairCom Edge OPC UA connector

Connect FairCom Edge to OPC UA devices

Abstract

OPC UA is a client/server unified architecture that supports OPC UA devices only

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.

The FairCom Edge OPC UA service can connect to and interact with OPC UA devices. This service is included in the FairCom jsonAction API. The FairCom Explorer Web Utility can pull, store, view, and use tags from an OPC UA simulator.

Note

A tag is named data, such as a temperature with a value of 70 . In JSON, a tag is a JSON property, such as "temperature": 70. In a SQL table, a tag is a data field, such as a field named temperature with a value of 70.
