Commands Of The Ident Profile - Siemens Simatic Ident Function Manual

Explanation of the data structure example
● CMDREF[1]:
Command "WRITE-CONFIG", OFFSETBUFFER = 0
At the "CMDREF[1]" point you need to set the "WRITE-CONFIG" command so that the
"INIT/Reset" is correctly executed.
● CMDREF[2]:
Command "WRITE", OFFSETBUFFER = 15
● CMDREF[3]:
Command "READ", OFFSETBUFFER = 0
If the "CMDREF[2]" command is selected, a write command is started and the data to be
written is fetched starting at byte 15 of the "TXREF" parameter. If the "CMDREF[3]"
command is selected, the read data is stored starting at byte 0 in the "RXREF" parameter.
