Commands Of The Ident Profile; Overview Of The Commands - Siemens SIMATIC Ident Function Manual

Configuring the instructions
4.6 Programming the Ident profile
Explanation of the data structure example
• CMDREF[0]:
Command "WRITE-CONFIG", OFFSETBUFFER = 0
At the "CMDREF[0]" point you need to set the "WRITE-CONFIG" command so that
the "INIT/Reset" is correctly executed.
• CMDREF[1]:
Command "WRITE", OFFSETBUFFER = 15
• CMDREF[2]:
Command "READ", OFFSETBUFFER = 0
If the "CMDREF[1]" command is selected, the Write command is started and the data to
be written is fetched from the "TXREF" parameter starting with element 15. If the
"CMDREF[2]" command is selected, the read data is stored starting at element 0 in the
"RXREF" parameter.
