5.16. emllRemote

The emllRemote is used to tunnel EtherCAT frames within a TCP socket between EC-Master and EC-Simulator.

The parameters to the Remote Real-time Ethernet Driver are setup-specific. The function CreateLinkParmsFromCmdLineRemote() in EcSelectLinkLayer.cpp demonstrates how to initialize the Real-time Ethernet Driver instance.

struct EC_T_LINK_PARMS_REMOTE

Public Members

EC_T_LINK_PARMS linkParms

Common link parameters. Signature must be set to EC_LINK_PARMS_SIGNATURE_REMOTE

EC_T_DWORD dwSocketType

Socket type. Must be set to 1 (emrassocktype_tcp)

EC_T_BYTE abySrcIpAddress[4]

Source adapter IP address (listen) (EC-Simulator)

EC_T_WORD wSrcPort

Source port number (listen) (EC-Simulator)

EC_T_BYTE abyDstIpAddress[4]

Destination adapter IP address (connect) (EC-Master)

EC_T_WORD wDstPort

Destination port number (connect) (EC-Master)

EC_T_BYTE abyMac[6]

MAC address

EC_T_DWORD dwRxBufferCnt

Frame buffer count for interrupt service thread (IST)

While EC-Simulator listens on the given port using emllRemote, the EC-Master can connect to it using emllRemote.
