Write request header Request header Parameter address
... 0x02 0x01 0x01 0x01 0x10 0x06 0x03 0xC4 0x00
0x00
The slave responds to the write request with a PROFINET
write response header.

The master reads the result of the operation from the drive
using a PROFINET read request header.

PROFINET
Read response header Request header Parameter value
... 0x02 0x01 0x01 0x01 0x42 0x06 0x01 0xBA 0x00
0x02 0x00 0x64 0x07
0xDE 0x00 0x65 0x00 0x01
The returned value consists of six words (0x42 means
Word, 0x06 is the number of values returned), and the
values are 0x01BA, 0x0002, 0x0064, 0x07DE, 0x0065, and
0x0001. Thus the following information can be determined
about the device:
•
Manufacturer code is 0x01BA
•
Drive Unit type is 0x0002
•
Software version is 1.0 (0x0064 = 0100d)
•
Firmware date (year) is 2014 (0x07DE)
•
Firmware date (day/month) is 1/1 (0x0065 = 101d)
•
The device contains one axis
8.3.4.3 Requesting the value of drive parameter ID 103
The following information is used for this request:
Table 56. Request value of parameter ID 103
Field Contents
Request reference 0x03
Request ID 0x01 = Request parameter
Axis Number 0x01
No. of Parameters 0x01
Attribute 0x10 = Value
No. of elements 0x01
Parameter Number 0x2711 (10001d)
Subindex 0x0067 (103d)
The request from the master is:
Table 57. Request from master
PROFINET
Write request header Request header Parameter address
... 0x03 0x01 0x01 0x01 0x10 0x01 0x27 0x11 0x00
0x67
The slave acknowledges the request with a PROFINET write
response header.
Table 58. Response from slave
PROFINET Write response header
...
The master reads the result of the operation from the drive
using a PROFINET read request header.
Table 59. Read request from master
PROFINET Read request header
...
The slave responds to the read request:
Table 60. Slave response to read request
PROFINET
Read response header Request header Parameter address
... 0x03 0x01 0x01 0x01 0x42 0x01 0x00 0x0A
The parameter value reveals that the format of the value is
“Word” (0x42), there is one value in the response (0x01)
and the actual value is 0x000A. Because this value was read
from the drive application, the Drive Application Manual
contains details on how to interpret the value. In this
example, the Acceleration time would be one second.
