IP address:
IP address of the card (read-only). The IP address is read from the operating system, and has nothing to do
with the PROFINET IP address that will be used later.
IP address of the network card
Please note that the IP address of the PROFINET device and the IP address of the Ethernet card
are not identical! The PROFINET driver works with a virtual IP address that must not be identical to
the IP address of the operating system!
Promiscuous Mode:
This is required in order to record Ethernet frames, and should normally be switched off.
Virtual Device Names:
A virtual name is used for the network card.
Shared Adapter Interface:
Is included for compatibility reasons, but cannot be used with PROFINET.
Free Cycle:
Cycle time in Config mode (no real-time). If TwinCAT is operated in FREERUN mode, care must be taken
that the freerun cycle set is no longer than the PROFINET cycle!
If, e.g., a CX9000 is to be parameterized, the target system must first be accessed remotely; the
corresponding Ethernet port can subsequently be selected.
The NetID used can be found under the "Protocol" tab. It is, e.g., necessary for an ADS access. Besides
that, there is a possibility in the "Sync Task" tab to append a free-running task for PROFINET communication
(this is recommended). This allows the RealTime communication to run independently of a PLC task. For
performance reasons, however (e.g. in the case of a CX9000), the Sync Tasks can be dispensed with and
standard mapping takes place, i.e. a PLC task, for example, must be running in order for PROFINET
communication to be possible.
A PROFINET protocol is then added by means of the right mouse button. Precisely one TwinCAT device
protocol can be appended!

A Box in the form of a GSDML is then integrated (right mouse button on "PROFINET Device").
