# emllRemote

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

The parameters to the Remote Driver are setup-specific. The function `CreateLinkParmsFromCmdLineRemote()` in [`EcSelectLinkLayer.cpp`](_downloads/bf62c71a4a7e317930818b9da4a9815c/EcSelectLinkLayer.cpp) demonstrates how to initialize the driver instance.
