Source-destination principle

The I/O configuration of the input and output signals is carried out according to the
source/destination principle:
 A connection always has a direction and therefore always has a source and a target.
 The inputs signals of the technology application are logically linked to the outputs of
system blocks which represent the device input terminals.
 The inputs of system blocks that represent the device output terminals are logically
linked to output signals of the technology application.
The following graphic illustrates the source/destination principle:
[6-5] Source-destination principle
Note the following:
 An equipment input terminal can be logically linked to several inputs of the application
block.
 Every input of the application block can only be logically linked to one input signal.
 An output of the application block can be logically linked to several device output
terminals.
