Description

The standard IEC 61850 of the International Electrotechnical Commission (IEC) describes a general transmission protocol for protection and control technology in electrical switchgear of medium and high-voltage technology (station automation).

Part 9-2 describes the so-called sampled values. These are currents and voltages measured in real time and sent via Ethernet frames. The acquisition of up to two streams is supported with one interface license. In total, a maximum of 4 licenses (=8 streams) can be used.

Sampled Values streams are sent by IEC 61850 devices as multicast ISO messages. ibaPDA can receive them via the computer's standard Ethernet interfaces.

Interface configuration

At the interface level, no settings need to be configured.

Connection table

The table shows different diagnostic values of the individual connections during data acquisition. To reset the update time, the message counter and the sequence errors to zero, click on the <Reset counters> button. The message counter is a continuous counter that is incremented by one with each received message. A message can contain several samples. The update time shows the measured time between samples. Sequence errors indicate that no continuous sequence counter was detected in successive messages that were received. The diagnostic data from this connection table can also be acquired via a diagnostic module. Each diagnostic module can be coupled to a Sampled Values stream via the Target module property.
