Explanation of Terminology and Functionality of the AFE
Indexed parameters
Data sets
9-2
These parameters are divided into various "indices" (i001, i002, etc.). A
separate parameter value can be assigned to each index.
The meaning of the "indices" of the relevant parameter (parameter
number) can be found in Section "Parameter List".
Example:
Index 1
P683 i001 = 0 Bus address of serial interface
Index 2
i002 = 2 Bus address of serial interface
"Indexed" parameters are divided according to data sets (indexed).
♦ GRD/RES (basic or reserve setting):
These data sets make it possible, e.g. to switch from manual to
automatic mode.
♦ RDS (reserve data set) 1 or 2:
Two reserve data sets can be parameterized, e.g. for alternating
operation of different converter types on one AFE.
The data sets are selected via the "control word" and read out in r012
and r152, see Section "Function Diagrams".
