Communication line which is subject to hardware disconnection
fault will also lead to execution failure in PKW area. The error
code will be given in status word of PZD area.
● Example of parameter operation in PKW area
In real application, the PROFIBUS adapter communicates with the master
through messages in PPO structure. Among the 5 PPOs stated in chapter
"PPO Data Type" on page 195 , PPO 1, PPO 2 and PPO5 apply both PKW
area and PZD area. In following examples, PKW area data frames are taken
from complete PPO message to describe its request and response data
frames.
The following examples are based on Bosch Rexroth Frequency Converter
Fv and PROFIBUS adapter.
Example 1
Reading value of parameter 'Skip frequency range' [S3.06]. 0×05 is the func‐
tion group, 0×06 is the index serial No. of the parameter within the group,
then request and response data frames in PKW area are shown in fig. 12-36
"Example 1_request and response data frames of PKW area" on page 198 .

ID of request data frame could be 0×1000 or 0×1800, because
the 11 th digit of ID in Table 4-1 can be 0 or 1. 0 is strongly recom‐
mended. In following examples, only ID value of 0with this digit is
given.
Example 2
Reading value of parameter 'Skip frequency range' [S3.06]. 0×05 is the func‐
tion group, 0×06 is the index serial No. of the parameter within the group. If
the index serial No. of group S3 is miswritten as 0×20 (0×20, exceeds speci‐
fied limit in group S), then request and response data frames in PKW area
are shown in fig. 12-37 "Example 2_request and response data frames of
PKW area" on page 199
