SCADA Topology
SCADA Topology
(OP)
I invite your comments on following SCADA topologies :
connecting IED's in star topology via a star coupler Vs connecting IED's in Ring topology via a switch
connecting IED's in star topology via a star coupler Vs connecting IED's in Ring topology via a switch






RE: SCADA Topology
Even for RS-485 or Ethernet, star is probably a safer, more reliable and simpler implementation, as long as distances are not too long.
RE: SCADA Topology
dpc, if some of the Ied in one substation are daisychained RS485 and in another substation has newer relay that has 10BaseT connection. and every substation connected by OPGW (that would be single mode FO). The length beetwen substation about 20 km. which one doyou choose ?
