2.1.3
Technology application = function block interconnection
In case of the 8400 device version, each technology application is connected to a "function block
interconnection" ("FB interconnection"). This FB interconnections serve to implement signal
interconnections. Various FBs are available for digital signal processing, signal conversion and logic
modules.
For special drive tasks it has proved of value to use the integrated technology applications as a basis
for modifications or extensions of the available FB interconnections.
• From "StateLine" version onwards, the preconfigured signal links can be reconfigured in the I/O
level by means of parameter setting or using the »Engineer« function block editor.
• Moreover, from the "HighLine" version onwards, the experienced user has the opportunity to
implement own drive solutions independent of the predefined technology applications by using
the "free interconnection".
I/O level & application level
The interconnection of the interfaces is shown in the I/O level of the function block editor according
to the control mode. In the "deeper" application level, the main signal flow is realised in the form of
an interconnection of various function and system blocks.
Motion Control Kernel
Important basic (drive) functions as well as further basic functionalities are implemented in the
firmware of the drive controller in the so-called Motion Control Kernel (MCK) which can be accessed
by the active technology application via defined internal interfaces. By this means the expensive
creation of single function block interconnections is omitted so that the expenditure and the
complexity for the realisation of standard functions is minimised.
The Motion Control Kernel is integrated in the main setpoint path and, depending on the set
operating mode, it creates the required control and setpoint signals for the motor control and the
drive interface.

• A detailed description of the basic functions implemented in the Motion Control
Kernel can be found in the main chapter "
