Restrictions

The size of the bus configuration file is limited by the size of the RAM Disk (1 Megabyte)
The configuration database interface and its structure and definitions apply for netX products which use the PROFINET IO Controller - firmware only.
Structures and functions described in this document apply only to hardware from 3rd party vendors insofar as original Hilscher firmware is concerned. Therefore, whenever the term "netX firmware" is used throughout this manual it refers to ready-made firmware provided by Hilscher. Although 3rd party vendors are free to implement the same structures and functions in their product, no guarantee for compatibility of drivers etc. can be given.
The following limitations apply
- The usable (minimum) cycle time depends on the number of used IO Devices, the number of used input and output data. See /wiki/spaces/TDAPIPNM3/pages/106040808 for details
- RT over UDP not supported
- Multicast communication not supported
- DHCP is not supported (neither for PROFINET IO Controller nor for the IO-Devices)
- Only one IOCR per IO-Device per direction
- NameOfStation and IP of IO Controller CANNOT be set using the DCP SET NameOfStation service but only at start-up while configuring the IO Controller
- only one instance of DeviceAccess AR can be used at the same time
- MRPD is not supported
- planing of IRT is not done by the PROFINET IO Controller protocol stack but an engineering topic
- Sync Slave is not supported
NXLOM is not available for this protocol stack
