The Acontis stack is divided into two parts. The Class B Master forms the basis. The Class A Master is an addon that allows synchronization with Distributed Clocks (DCM = Distributed Clocks Master Synchronization).

1. atemsys [atemsys.ko]
   • Linux kernel module. Grants direct HW access from user space.
   • Must be compiled for the kernel used.
   • Sources/LinkOsLayer/Linux/atemsys
   • How to build
2. EtherCAT Master Core[libEcMaster.a]
   • Base of the EtherCAT stack.
   • SDK/LIB/Linux/x64/libEcMaster.a
3. EC LinkLayer [libemllI8254x.so]
   • Library EtharCAT Master Link Layer for Intel8254X EtherNet hardware.
   • Special Ethernet hardware driver optimized for use with EtherCAT.
   • Replaces the installed ethernet driver
   • Different LinkLayer may be needed for different Ethernet Hardware
   • Check compatibility list in EC-Master_ClassB.pdf 2.3.1.3 Supported network controllers
   • Bin/Linux/x64/libeml8254x.so

The Acontis stack can be used without limitation for 1 hour. After this the stack stops working. To overcome this limitation you have to acquire runtime licences from Acontis.
