PTP vs IRIG B � IRIG B is a serial time code TTL (00x) or modulated on 1 kHz carrier (12x) which use a separate network cabling for the sole purpose of timing Over coax (deasy-chain with impedance restrictions) � Over fiber (point-to-point) � PTP/IEEE1588 � Uses Ethernet protocol as transport network – date and timing can be mixed on � same network cabling Ethernet is a naturally multipoint /broadcasting network � Accuracy in the range of nanoseconds � IEC61850 also define Ethernet as communication network within electrical � installations PTP reduces HW cost in Grandmaster clock as well as IED/RTU � �� Digital Instruments S.r.l.
Conclusions � PTP allows to use a single communication network (Ethernet based) for both data and timing within the substation and reduces cost for both GM clock and IED/RTUs � SB-V01 has multiple inputs and outputs actng as: � IRIG B to PTP converter for adding new IED/RTU to legacy IRIG B substations � PTP to IRIG B converter for adding legacy IED/RTU to new PTP enabled substation � IRIG B extender using optical In/Outin daisy-chain and connecting new enabled PTP/IED/RTU at any point in the IRIG B bus � Grandmaster Clock when GNSS module is equipped �� Digital Instruments S.r.l.
