Configure I/O for Use with AVEVA Telemetry Server Communication Drivers

If you are using AVEVA Telemetry Server Communication Drivers to send and receive data from Application Server, you will need to configure I/O attributes, in accordance with the applicable communications protocol. The Telemetry Server communicates with outstations via the DNP3, IEC-60870, and/or Modbus protocols. Use the reference syntax that corresponds with the protocol you are using. Since some outstations may send data to the Telemetry Server only once per day, you will also need to enable buffering to ensure that data is not lost.

Note: If multiple attributes with I/O enabled are configured for buffered data from the same data point in the Telemetry Server, only one attribute will receive the buffered data at run time.

Note: The IEC-60870 protocol is not supported in AVEVA Telemetry Server version 1.0.

Dynamic References

You can configure Telemetry Server data points using dynamic references. When you create and deploy an attribute with a dynamic reference in Application Server, the point is automatically generated on the Telemetry Server, and eliminates the need to manually create the same reference in two places.
