● Corresponding to function diagram FP7990, different measuring tasks are uniquely
assigned to the various VSM10 devices; it is not permissible to change this assignment.
For an assignment of the various VSM10, see the diagram in the subsequent chapter, the
assignment of the VSM10 to the numbers in the diagram are as follows:
VSM_1 =
– VSM_1 is, according to a possible parallel connection of power units and grid filters,
– VSM_2 is defined with p0151[0]; the measured values are displayed in r5461[0] and
– VSM_3 is defined with p0151[1]; the measured values are displayed in r5461[1] and
