6.3 PROFIBUS-DP parameter-setting channel
The PROFIBUS DP parameter-setting channel offers a parameter setting and diagnostics possibility
for controllers. It is therefore possible to access all Lenze parameters (codes).
If the DP parameter-setting channel is active, it assigns the first 8 bytes of the and input and output
data. The DP parameter-setting channel has the same structure for both transmission directions.

Byte 1: Service
Job and response control for the DP parameter-channel.
Bit no. Meaning
0 - 2 Service
Job for the controller. The bits are set only by the master.
l 0 = no job
l 1 = read job (read data from the controller)
l 2 = write job (write data to the controller)
3 Reserved
4 - 5 Data length
Length of the data in the field data/error.
l 0 = 1 byte
l 1 = 2 byte
l 2 = 3 byte
l 3 = 4 byte
6 Handshake
Indicates a new job. The master changes this bit for every new job. The controller copies the bit to its response message.
7 Status
Status information from the controller to the master when sending acknowledgement. This bit informs the master whether the job
was carried out without faults.
l 0 = Job completed with fault.
l 1 = Job not completed. A fault occured. The data in the field Data/Error are interpreted as error message.
