The substation topology consists of the substation, voltage level and bay nodes. The bay nodes include also the conducting (primary) equipment, which corresponds to the switches, that is, the circuit breakers, disconnectors, and earth switch, of the configured IED. REX610 1.0 does not support automatic mapping of conducting equipment in the substation topology. Thus, IET600 or an equivalent tool should be used for engineering.
At the moment, the IEC 61850 Configuration tool does not support engineering of the substation section. Instead, IET600 or an equivalent tool can be used for engineering, if needed.
