Parameter Identifier Example
Parameter Index (IND) (2nd Word)
The index (also referred to as a subindex in the PROFIBUS profile) is an 8-bit value and is always transmitted on
PROFIBUS-DP in the most significant byte (bits 8 to 15) of the parameter index (IND); the least significant byte
(bits 0 to 7) of the parameter index (IND) has the value 0.
When a parameter has an index, the index is also transmitted. The number of the element is transmitted with a
description element. The meaning of the description elements is given in the PROFIBUS variable speed drives
profile (VDI/VDE 3689).
The index is not used for the inverter’s basic parameter set.
