Technology application = function block interconnection

In case of the 8400 device version, every technology application is based on a "function
block interconnection" (abbr.: "FB interconnection"). Using this FB interconnection, any
signal interconnection can be implemented. Various function blocks are available for
digital processing, signal conversion and logic modules.
For special drive tasks, it has proved of value to use the available FB interconnection of the
integrated technology applications as a basis for modifications or extensions.
 From the "StateLine" device version onwards, the preconfigured signal connections can
be reconfigured via parameter setting or via the »Engineer« function block editor in the
"I/O level".
 Moreover, from the HighLine device version experienced users are offered the
opportunity to implement their own drive solutions independent of the predefined
technology applications by using so-called "free interconnections".
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 selected 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.
