Structure of the PROFINET parameter channel
Parameterization via PROFIdrive Data Set 47
Example for writ-
ing a parameter
via MOVILINK
®
The following tables show the sequence of the WRITE and READ services for volatile
writing of the value 12345 to IPOS
plus®
variable H0 (parameter index 11000) as an ex-
ample. The MOVILINK
®
service WRITE Parameter volatile is used for this purpose.
Send "WRITE parameter volatile" request
The following table shows the WRITE.request user data for MOVILINK
®
"Write Param-
eter volatile".
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.
Service WRITE. request Description
API 0 Fixed setting = 0
Slot_Number 0 Random (is not evaluated)
Subslot_Number 1 Fixed setting = 1
Index 47 Index of the dataset for the parameter request; constant index 47
Length 16 16-byte user data for order buffer
Byte Field Value Description
0 0x01 Individual reference number for the parameterization
request is mirrored in the parameterization response
