Functional diagrams

The functional diagrams describe the default input, output, alarm LED and function
to function connections. The default connections can be viewed with SMT and
changed according to the application requirements, if necessary.
The analog channels, measurements from CTs and VTs, have fixed connections
towards the different function blocks inside the IED's standard configuration.
Exceptions from this rule are the 12 analog channels available for the disturbance
recorder function. These channels are freely selectable and a part of the disturbance
recorder's parameter settings, thus not included in the SMT functionality.
