In IEC 61850, function mode handing is defined in control model. In REX640, function mode parameters are not changed during normal operation, but they are set up during the engineering phase. Therefore, the most relevant of the “Operation” parameters are defined in the Settings menu.
For instant change of the configuration scenario, the setting group concept with blocking signals is recommended. Another alternative for the operator role is to use the controllable single- and double-point status from relevant application functions.
