Pkw Mechanism For Processing Parameters; Parameter Area (Pkw); Parameter Identifier (Pke), 1 Word - Siemens Micromaster Profibus Instruction Manual

Using the PKW mechanism you can process and monitor parameters (write/read)
as described below:
PPO type 1 on MICROMASTER4 in accordance with PROFIDrive Profile version
2.0
or
use of acyclical channel in conjunction with data block 100
The parameter area includes at least 4 words.
Bit no.:

The parameter identifier (PKE) is always a 16-bit value.
Bits 0 to 10 (PNU) contain the number of the relevant parameter.
Bit 11 is reserved.
Bits 12 to 15 (AK) contain the request or the response identifier.
The meaning of the request identifier for request telegrams (master → converter) is
shown in Table 3-3. Request identifiers 11 to 14 are specific to MICROMASTER
and not defined in the PROFIDrive Profile.
The meaning of the response identifier for response telegrams (converter →
master) is shown in
Table 3-4. The request identifier will determine which response identifiers are
possible. If the response identifier is 7 (cannot process request), then one of the
fault numbers listed in Table 3-5 will be stored in parameter value 2 (PWE2).
