Real-time Ethernet port multiplier30
Version: 2.6
Fig.31: Installation of the Beckhoff real-time driver
Characteristics that are important for the further operation, e.g. the MAC and the IP addresses of the Gbit
network port are now listed in the adapter characteristics of the MultipleProtocolHandler.
Fig.32: Adapter data for the Gbit Ethernet port used
Name Explanation
Description Name of the adapter in the operating system (the same on several identical PC systems)
Device Name Unique adapter name (different on several identical PC systems)
MAC Address MAC address of the hardware adapter; not changeable
IP Address IP address of the hardware adapter; changeable via the Windows operating system
"Network Connection" settings
Freerun Cycle The adapter is now operated in ConfigMode with this cycle time, i.e. usually 250 cycles/
sec.
Promiscuous
Mode
If activated, the Ethernet Frames are copied from the real-time context into the Windows
NDIS layer and can thus be read by Netmon/Wireshark
Virtual Device
Names
deactivated:
"Device Name" is used by TwinCAT for the identification of the network adapter. Thus a
TwinCAT configuration is not transferable to another PC system without being changed.
activated:
"Description" is used by TwinCAT for the identification of the network adapter. Thus a
TwinCAT configuration is transferable to another PC system without being changed if an
adapter with this name is present there.
The number of necessary ports must be set in the port mask (A). The TCP/IP mode of operation is also to be
set (B); "via EoE" must be set for pure EtherCAT operation. Refer here to the Notes on TCP/IP settings
[}40]. In each case the ESL protocol must be activated for the CU2508 on this Gbit port (C).
