  For the system bus, the input data of the TxPDO’s are also displayed as input parame-
ters and the output data of the RxPDO’s as sources. 
  Example 2: 
Function A
Inverter 1
Function B
Inverter 1
Source-No. 27
Source-No. 5
TxPDO
Inverter 1
Parameter 977
Parameter 972
system bus
RxPDO
Inverter 2
Source-No. 727
Source-No. 724
Function C
Inverter 2
Parameter 125
Parameter 187
system bus
  Example 2 displays the same situation as Example 1. But now, the functions A and B
are in frequency inverter 1 and function C in frequency inverter 2. The connection is
done via a TxPDO in frequency inverter 1 and a RxPDO in frequency inverter 2. Thus, 
the parameterization for this connection is: 
  Frequency inverter 1 
    Parameter 977 = Source-No. 27 
    Parameter 972 = Source-No. 5 
  Frequency inverter 2 
    Parameter 125 = Source-No. 727 
    Parameter 187 = Source-No. 724 
  As the links with the system used exceed the device limits, they are termed "virtual
links".
