Operating Behavior (PROFINET IO)
11.3.3 Parameter setting procedure via data record 47
Parameter access takes place with the combination of the
WRITE RECORD
and
READ
RECORD
PROFINET services. The parameter setting order is transferred to the IO de-
vice using the
WRITE.req
, Then it is processed internally.
The controller now sends a
READ.req
to pick up the parameter setting response. The
device sends a positive response
READ.res
. The user data now contain the parameter
setting response of the parameter setting order that was previously sent with
WRITE.req
(see the following figure). This mechanism applies to a PROFINET controller.
