Adapter

This dialog specifies and parameterizes the network card to be used for communication with the PROFINET Device.

OS (NDIS)

This option uses the operating system (OS) settings for installed network cards. The name of the network card is displayed in Description. Device Name contains the Device Manager path of the installed network card.

PCI

This option controls the network card via the PCI bus address, which is specified in the PCI Bus/Slot field.

The PCIBus/Slot field is not enabled until the PCI option is selected

DPRAM

This option controls the network card via the DPRAM address, which is specified in the Address field.

The Address field is not enabled until the DPRAM option is selected

Search... button

This button opens a dialog in which all unused or all compatible devices (adapters) are offered for selection.

Compatible Devices… button

This button opens the same dialog as TWINCAT\ Show Real-time Ethernet Compatible Devices... in the main menu. Use the dialog box to determine if compatible Ethernet adapters are available on the system.

MAC Address

MAC address of the Ethernet card (read-only)

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.

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.

Adapter Reference

If the network adapter is referenced to another device, this option must be selected. This is used, for example, when using the "Multiple Protocol Handler".

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.
