Erbessd Phantom OPC UA
The Gateway version 2 for the wireless sensor system Erbessd Instruments Phantom® supports the OPC UA industrial protocol. All sensor processed data is available trought OPC. Due how the OPC UA protocol works the full time waveform or FFT is not available.
The gateway acts as a OPC UA server and listens for TCP connections on port 4334.
Enabling the OPC Server
To enable the OPC UA server, in the Gateway 2 admin console, enable it in the General config page by clicking the “Enable OPC UA Server” checkbox. Click save and the Gateway will restart. After the Gateway restarts the OPC Server will be ready.
You can use the OPC UA server at the same time of all other protocols supported by the Gateway. Including EI Analytic, EI Monitor, MQTT and Modbus.
After the OPC UA server has been enabled you can access the server using the following URL with a OPC UA client: opc.tcp://192.168.1.2:4334/UA/PhantomGW where 192.168.1.2 is to be replaced by the IP address of your gateway. Use security mode none and security policy none.Â
The OPC UA is organized in a tree like structure. For the Phantom Gateway Under the root folder there will be a Object folder under which all the sensor serial numbers will be shown. Under each serial number there will be a number of different variables depending on the sensor type.
Variables
The type variable will contain the type of the sensor according to the following table:
| 3, 5 and 6 | Triaxial accelerometer |
