2.4. NDIS Driver

The Network Driver Interface Specification (NDIS) is the specification for a network driver architecture that allows transport protocols like TCP/IP to communicate with an underlying physical network adapter. For analyzing EtherCAT frames in Windows, EC-Inspector makes use of the well-known Windows packet capture library, WinPcap. However, WinPcap was based on the NDIS 5.x driver model, and development has ceased. The latest versions of Windows 10 do not support this old NDIS 5.x version anymore, so now EC-Inspector V3.4 includes an installation package to install the acontis NDIS 6.x Filter Module EcatNdis.sys. With this new Filter Module and the new NDIS Link Layer emllNdis.dll, it is now possible for EC-Inspector to work without WinPcap on all Windows 10 versions.
