Functional diagrams for measurement functions

The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card in
the back panel. The sequence current measurement CSMSQI1 measures the sequence
current and the residual current measurement RESCMMXU1 measures the residual
current.
