Station communication

Figure 219: Quality expander block in ACT
The expanded quality bits are visible on the outputs as per IEC 61850-7-3 standard. When
written to IED, the configuration will show the expanded form of the respective MU channel
quality information during the online monitoring in the ACT.
17.4 LON communication protocol
17.4.1 Application
IED
IEC05000663 V2 EN-US
Figure 220: Example of LON communication structure for a substation automation
An optical network can be used within the substation automation system. This enables
communication with the IEDs through the LON bus from the operator's workplace, from the
control center and also from other IEDs via bay-to-bay horizontal communication. For LON
communication an SLM card should be ordered for the IEDs.

The quality expander function is intended for monitoring purposes, not for
being used in a logic controlling the behaviour of the protection or control
functions in the IED. The function outputs are updated once every second and,
therefore, do not reflect the quality bits in real time.
