OPC UA connector
Connect FairCom Edge to OPC UA devices
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 uses a field bus protocol that can connect to and interact with OPC UA devices to read and write OPC UA data tags to and from devices, such as PLCs. The time between data collection events can be modified. For example, to collect data twice every second, set "dataCollectionIntervalMilliseconds" to 5000. 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 a piece of named data with an associated value. For example, the tag temperature 70 includes both the named data temperature and the value 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.
