The configuration includes the logic for generating the circuit breaker external closing
and opening command with the IED in local or remote mode.
Check the logic for the external circuit breaker closing command and
modify it according to the application.
Connect additional signals for opening and closing of circuit breaker
in local or remote mode, if applicable for the configuration.

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.
The three-phase bus side phase voltage inputs to the IED are measured by three-phase
voltage measurement VMMXU1. The voltage input is connected to the X130 card in
the back panel. The sequence voltage measurement VSMSQI1 measures the sequence
