Data Record Interface of the IE/AS-i LINK

Significance and Functionality
Using the data record interface, you can control the response of the AS-i master
completely from your user program.
AS-i calls are read and written using the acyclic services of PROFINET IO. You
can do this in the user program of the PROFINET IO controllers with the
"RecordDataRead" (read data record) and "RecordDataWrite" (write data record)
services.
