Table 262. Station communication functions
Function
IEC 61850-9-2 Process bus communication, 8 merging units
IEC 62439-3 Parallel redundancy protocol
IEC 62439-3 High-availability seamless redundancy
Synchrophasor report, 8 phasors
Rapid spanning tree protocol
1) PRP, HSR and RSTP require two SFPs placed in pairs.
2) This functionality requires accurate time synchronization, therefore either 'Precision Time Protocol (PTP) Time synch or GTM or IRIG-B will be required.
