Conditions required for operation
The following points must be observed when using the PROFINET supplement:
• Only Ethernet cards with Intel chipset allowed.
• RealTime Ethernet driver must be installed.
• No other RealTime protocols must be connected through this interface.
• The real-time capability can only be guaranteed in the transmit direction; in the receive direction,
the possibility of incorrect use means that it cannot be guaranteed. This might, for example, be
the copying of large quantities of data through this interface.
It is recommended that the PROFINET network is separated from other networks.
