Structure of the PROFINET parameter channel
Parameterization via PROFIdrive Data Set 47
Example for writ-
ing a parameter
via PROFIdrive
The following tables show an example of the structure of the WRITE and READ services
for the remanent writing of the internal setpoint n11 (see section "Example for writing a
parameter via MOVILINK
®
", page 79). The Change parameter PROFIdrive service is
used for this purpose.
Send "WRITE parameter" request
The following table shows the PROFINET header of the WRITE request with parame-
terization request.
The following table shows the WRITE.req user data for the "Change Parameter" PRO-
FIdrive service .
After sending this WRITE.request, the WRITE.response is received. If there was no sta-
tus conflict in processing the parameter channel, a \positive WRITE.response occurs.
Otherwise, the status error is located in Error_code_1.
