Parameter ID (PKE) and parameter index (IND)
The parameter ID (PKE) is always a 16 bit value. In conjunction with the index (IND), it
defines the parameter to be transferred.
PKE structure
● The parameter number is encoded in the lower 11 bits (PNU) of the PKE. Since the PNU
● Bit 11 (SPM) is reserved and is always 0.
● Bits 12 to 15 (AK) contain the request or response ID.
The meaning of the request ID for request telegrams (master → inverter) is explained in the
following table.

can only contain values up to 2000, an offset must also be encoded for parameter
numbers above 2000. The offset is set in the first word of the index (IND) as shown in the
table below.
