5.4. Beckhoff CCAT - emllccat

The parameters to the CCAT Link Layer are setup-specific. The function “CreateLinkParmsFromCmdLineCCAT” in EcSelectLinkLayer.cpp demonstrates how to initialize the Link Layer instance. Because the link status cannot be read quickly from a register of the adapter, it will not be automatically refreshed like by the other Link Layers.
