Figure 46: Typical topology in power system communication environment 

The logically network the switches do when using VLAN traffic segregation is shown 
below. 

 

Figure 47: Logical topology of typical power system communication environment 

IEC  61850  documents  recommend  to  use  different  methods  of  redundancy  at  Station  and  Process  communication  bus.  For 
simplification, these redundancy requirements are not shown nor discussed in this chapter.
