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

The toolchain consists of several components and libraries, some of which were purchased and some of which were developed in-house.

1. EtherCAT Master Core[libEcMaster.a]
   • Base of the EtherCAT stack.
   • EC-Master-V2.9-Linux_x64-Eval/SDK/LIB/Linux/x64/libEcMaster.a
2. atemsys [atemsys.ko]
   • Linux kernel module. Grants direct HW access from user space.
   • Must be compiled for the kernel used.
   • EC-Master-V2.9-Linux_x64-Eval/Sources/LinkOsLayer/Linux/atemsys
   • How to build
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
   • EC-Master-V2.9-Linux_x64-Eval/Bin/Linux/x64/libeml8254x.so

„EC-Master-V2.9-Linux_x64-Eval/SDK/LIB/Linux/x64/libAtemRasSrv.a“ Remote API Server, i.e. with EC-Lyser (optional?)

These components are only required if the stack is used together with EEROS.

1. EEROS Application [movingchair] The control application itself which is specially designed for each individual robot.
2. EEROS [libeeros.so] the roboter framework.
3. [ecmasterlib] Interface between Acontis and EEROS application (from NTB addapted EC-Demo of acontis „EC-Master-ClassA-AddOn-V2.9/Examples/EcMasterDemoDc“)
