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.

 More detailed information:

• A detailed description of the basic functions implemented in the Motion Control

Kernel can be found in the main chapter "Basic drive functions (MCK)

". ( 437)

• Detailed information on the creation or change of interconnections by means of the

function block editor can be found in the main chapter "Working with the FB Editor

( 1102)

• All available function and system blocks are described in the main chapter "Function

library". ( 1154)
