12.16.3 Process data transfer
The process data is used to control the inverter.
•
The process data is transmied cyclically between the IO-Controller and the IO-Devices
parcipang in PROFINET.
•
The process data can be directly accessed by the IO controller. The data in the PLC, for
instance, are directly stored in the I/O area.
•
The available 27 network registers ("slots") serve to maximally exchange 16 process data
words (data types 8-bit or 16-bit) or 8 process data double words (data type 32-bit) for
each direcon.
•
Output data direcon: From IO-Controller to IO-Device.
•
Input data direcon: From IO-Device to IO-Controller.
Data mapping
Data mapping is used to dene which process data is exchanged cyclically between IO-Con-
troller and IO-Device.
•
If the inverter is known as IO-Device in the PROFINET network and the IO-Controller con-
nects to the inverter for the rst me, the mapping objects are automacally transmied
to the inverter.
•
Internal mapping of the process output data: 0x24E0:001 ... 0x24E0:016
•
Internal mapping of the process input data: 0x24E1:001 ... 0x24E1:016
All subsequent changes in the objects 0x24E0 and 0x24E1 can cause PROFINET
alarms according to the deviaon from the automacally set conguraons.
