Figure 7-63 Structure/Embedding of the 3-Phase Voltage/Current Function
A maximum of 3 function blocks of the same type can be entered or removed within the function. For unam-
biguous differentiation the function blocks automatically receive a sequential number in the name of the func-
tion block, for example, Trig I RMS 1, Trig I RMS 2, and Trig I RMS 3.
Each function block contains the level trigger Max. trigger and Min. trigger, as well as the gradient
trigger dM/dt rise (/Filter time) and dM/dt drop active of the corresponding measurand.
