PKW area (parameter identification marks PKW1-value area). PKW area describes treatment of
parameter identification interface, PKW interface is a mechanism which determine parameters
transmission between two communication partners, such as reading and writing parameter values.

In the process of periodic PROFIBUS-DP communication, PKW area is composed of four words (16
bit), each word is defined as follows:
The first word PKW1 (16 bit)
Bit 15–00
Task or response identification marks
0–7
The second word PKW2 (16 bit)
Bit 15–00
Basic parameters address
0–247
The third word PKW3 (16 bit)
Bit 15–00
Parameter value (high word) or return error code
