PCS-9785  Satellite-Synchronized  Clock

 

3-2 

Date: 2019-07-05 

3.1.3 Output Function 

The output function converts the internal clock information into various time codes, such as 
PPS/PPM/PPH, IRIG-B, serial code, SNTP/NTP, IEEE1588, etc. Then, it outputs these time codes 
via different interfaces, such as TTL, optical-coupled contact, RS-485/422, RS-232, optical fiber, 
AC modulation, RJ45,etc. for other IEDs. 

3.2 Double Devices Redundancy Strategy 

This device can work in the double devices mode with another one to ensure the time accuracy. 
The two devices are interconnected by two optical fibers in using of IRIG-B signal. 

Normally, each device receives time signal from its own satellite receiver and decodes/converts 
the signal for output. If the satellite tracking of one of these two devices is lost, the lost will take the 
interconnection IRIG-B signal as its external time reference. Else if both the two have lost their 
satellite tracking, the internal clock of the device, which lost its tracking signal later, will be used as 
the time source. 

3.3 PRP/HSR 

3.3.1 Parallel Redundancy Protocol (PRP) 

3.3.1.1 Network Mode 

As same as dual star networks, PRP nodes connect to two completely independent parallel 
networks, and each node sends two copies of the same packet to LAN A and LAN B respectively, 
while receiving nodes accept the first packet and discard the second. Both LAN A and LAN B will 
transmit those messages to receiving nodes, and the receiving nodes will transmit data to 
application layer. 

PRP nodes send two copies of the same packet via PRP network, two copies of the same packet 
are transmitted via dual switch networks, and receiving nodes make a redundant handling at the 
data link layer to realize redundant message receiving.
