Chapter 8 PROFINET Specification
8.12 Parameter access
You can access the parameter by Record Data CR. When you access the parameter, you need to set
0xB02E to index.
8.12.1 write data record and read data record
First you need to send a request of parameter read or write to WJ-PN by write data record (e.g.
WRREC) from PROFINET IO controller or supervisor.
Next you need to send a request to read the response to WJ-PN by read data record (e.g. RDREC)
from PROFINET IO controller or supervisor. If there is an error, the reply to a Read or Write service is
an error response.
Please refer to the PROFIdrive specification or a manual of PROFINET IO controller or supervisor
that you use.
