The 6 words of input data are divided into the following data areas:
Octet 1 Parameter identifier
Octet 2
Octet 3 Parameter subindex
Octet 4 Reserved
Octet 5
Octet 6 Parameter value
Octet 7
Octet 8
Octet 9 High-order byte of main

General example:
Set the "z" release setting current to a value of 25 kA.
Enter the following codes in the input area (AW 0 - 6) of the DP/RS 485 interface (3WN6):
DW no. Value
AW 0 KF= +00782
AW 2 KY= 005,000
AW 4 KY= 022,000
AW 6 KF= +25000
and then enter the request identifier for transferring a value (A 0.4 & A 0.5 = 1, in AW = 0).
