The 350 relay has an internal real time clock that performs time stamping via IRIG-B for
various features such as the event and transient recorders. This time stamping is available
with the IRIG-B signal connected to the relay terminals and set to "Enabled". When an IRIG-
B device is connected to the relay terminals, the relay detects the DC shift or the Amplitude
Modulated signal automatically. Time stamping on multiple relays can be synchronized to
± 1.0 ms with the use of IRIG-B input. Time stamping is also optionally available using SNTP.
Time synchronization priority uses the IRIG-B and SNTP protocols - via Modbus, IEC60870-
5-103, IEC60870-5-104, or DNP commands - as follows:
IRIG-B has the highest priority, so any other source of synchronization should be rejected if
IRIG-B is the synchronization source and an IRIG-B signal is available.
PTP (V2) has the second highest priority, so if IRIG-B is not the synchronization source but
PTP is, then any other source of synchronization should be rejected. SNTP has the third
highest priority.
Synchronization commands are all eventually translated into a MODBUS function, and as
such are blocked from the MODBUS layer as required.
Any synchronization commands other than Modbus, IEC60870-5-103, IEC60870-5-104, or
DNP will be accepted only if IRIG-B, PTP, and SNTP are not the synchronization sources.
There is no prioritization amongst synchronization commands. A synchronization
command issued from DNP for example, can be directly followed by another from
MODBUS, for example.
The following path is available using the keypad. For instructions on how to use the
keypad, please refer to Chapter 3 - Working with the Keypad.
