The derived quality is the extension to IEC 61850-7-3. If the derived bit is set to 1,
it indicates that there is no physical sensor within the system to determine the
value, but the value is derived from a combination of values from other physical
sensors. Typically, I4 or U4 are derived if they are calculated as the sum of the
three phase quantities.
The configured MU channel quality as described in IEC 61850-7-3 is available on
LHMI. This can be viewed under Main Menu/Diagnostics/Merging units/
MUX:XXXX/XX Quality.

Protocol
Communication speed for the IEDs
LON communication protocol
Functionality
An optical network can be used within the substation automation system. This
enables communication with the IED through the LON bus from the operator's
workplace, from the control center and also from other terminals.
LON communication protocol is specified in LonTalkProtocol Specification
Version 3 from Echelon Corporation and is designed for communication in control
networks. These networks are characterized by high speed for data transfer, short
messages (few bytes), peer-to-peer communication, multiple communication
media, low maintenance, multivendor equipment, and low support costs. LonTalk
supports the needs of applications that cover a range of requirements. The protocol
