| # Nifi OPC-UA Bundle | ||
|
|
||
| This is a bundle of OPC UA controller service and processors for Nifi. The bundle is an improvement built on top of the OPC UA bundle made by `HashmapInc.`(source code here: [https://github.com/hashmapinc/nifi-opcua-bundle](https://github.com/hashmapinc/nifi-opcua-bundle) ) | ||
| A couple of differences between the new bundle and the `HashmapInc.` one: | ||
|
|
||
| 1. The `HashmapInc.` is based on [OPC UA-Java Stack](https://github.com/OPCFoundation/UA-Java), which provides more bottom-level APIs. The new bundle is based on [Apache Milo](https://github.com/eclipse/milo), which is built on top of [OPC UA-Java Stack](https://github.com/OPCFoundation/UA-Java) but provides more high-level APIs and more advanced functionalities such as *subscription*. | ||
| 2. The new bundle adds a `SubscribeOPCNodes` processor, which allows the user to specify a list of OPC tags to subscribe to. The processor will produce flowfiles, when value changes on subscribed tags are detected. | ||
| 3. Adds an option to the `GetOPCData` processor so that the user can specify the source of tag list as a local file. The processor will get values of all tags listed in the file from the OPC. | ||
| 4. Adds an option to the `ListOPCNodes` processor, so that user may choose to not get nodes which are not leaves of the tree. This could come in handy, since in most cases, only leaf nodes contain value. | ||
| 5. Minor tweaks to improve performance as well as to adapt to our use case. | ||
|
|
||
| ## Build Instructions | ||
| Build it with Maven: | ||
| ``` | ||
| mvn clean install | ||
| ``` | ||
| Find the built nar file here: | ||
| ``` | ||
| <repo directory>/nifi-custom-listen-tcp-nar/target/nifi-opcua-nar-<version number>.nar | ||
| ``` | ||
| and copy it to the following directory of the running Nifi instance: | ||
| ``` | ||
| /opt/nifi/nifi-1.4.0/lib | ||
| ``` | ||
| Restart Nifi, then you can find the new processors available. |
