Streams
When you have created the required endpoints, you can then proceed to set up a data stream. A data stream sends data from one
endpoint to another, performing any transformation of the data as required. When a stream is added, an underlying process on the
router checks the validity of the stream, checking for conflicts and illogical configurations. To access the Streams page, click on the
Services menu at the top of the screen, click on the Data stream manager menu then click on the Streams menu item on the left.
Every stream requires two endpoints, Endpoint A and Endpoint B. In all cases, the flow of data is from Endpoint A to Endpoint B.
To create a new stream:
1.
Click the +Add button on the right side of the page.
Figure 88 - Data stream list
The Edit data stream page is displayed.
2.
In the Data stream name field, enter a name for the Data stream.
3.
Under Endpoint A, use the Endpoint name drop down list to select one of the endpoints you created previously. This
endpoint should be the starting point of the stream. Use the Mode drop down list to select the mode of operation of the
endpoint. The mode can be thought of as a transformation of the data as it leaves this endpoint. For example, if Endpoint
A type is Serial port (generic), the Mode can be set to various Modbus server and client types. This means that upon arrival
at Endpoint A, the data will be transformed into the chosen Modbus format, ready to be sent to Endpoint B.
4.
Under Endpoint B, use the Endpoint name drop down list to select one of the endpoints you created previously. This
endpoint should be the destination of the stream. The screenshot below shows a configuration sending data received on
an attached serial port to a TCP server running on the router. Use the Mode drop down list to select the mode of operation
of the endpoint. The mode can be thought of as a transformation of the data as it arrives at this endpoint.

Notes on data stream operation:
•
When any changes to the Data stream manager configuration are detected, all data streams are stopped and
restarted as per the new configuration.
•
Multiple Modbus clients cannot connect simultaneously to Modbus serial slaves connected to the router.
