(1) these sizes includes potential padding that could be inserted for variable alignment.
The following limitations apply:
The usable (minimum) cycle time depends on the number of IO-devices and the total size of input
and output data. For example it is not possible due to performance reasons to have 128 IO-devi-
ces communicating with a cycle-time of 1 ms.
RT over UDP, RT Class 2 and RT Class 3 (IRT) are not supported
Multicast communication is not supported
DHCP is not supported (neither for the PROFINET Controller nor for the IO-devices)
Only one input IOCR and one output IOCR per IO-device
Only one API (API = 0) is supported. Any profile requesting a different API is currently not suppor-
ted.
The IO-device feature “FastStartUp” cannot be used
WriteMultiple-Record service is not supported
System Configuration
The ME1PN1FW-Q uses high speed data transfer for the data exchange with the controlling CPU. It
can only be used in combination with QnU-CPUs, which support high speed data transfer. The follo-
wing QnU-CPUs do not support high speed transfer and therefore cannot be used

Mounting the PROFINET Controller in a PLC Rack
The PROFINET Controller must be placed in a slot to the right of the controlling QnU-CPU, but not
necessarily next to it. Additional QnU-, Motion- or NC-CPUs can be placed between the controlling
QnU-CPU and the PROFINET Controller. Intelligent and I/O modules are supported in the slots follo-
