 MODBUS USER MAP

The Modbus user map provides read-only access for up to 256 registers. To obtain a memory map value, enter the desired
address in the
ADDRESS
value of "0" in subsequent register
by "1". An address value of "0" in the initial register means "none" and values of "0" display for all registers. Different
5
values can be entered as required in any of the register positions.

 REAL TIME
 CLOCK
The relay contains a real time clock (RTC) to create timestamps for communications protocols as well as for historical data,
such as event records and oscillography. When the relay restarts, the RTC initializes from an onboard battery-backed
clock, which has the same accuracy as an electronic watch, approximately ±1 minute per month (~23 ppm). Once the RTC
is synchronized with the Precision Time Protocol (PTP), IRIG-B, or SNTP, its accuracy approaches that of the synchroniz-
ing time delivered to the relay. While the RTC is not synchronized via PTP or IRIG-B, or the relay determines than it has an
offset possibly greater than 10 µs from the international time standard, the CLOCK UNSYNCHRONIZED FlexLogic oper-
and is activated.
The
SYNCHRONIZING SOURCE
ures the priority sequence of the time synchronization source, to determine which of the available external time sources to
use for time synchronization. A setting of None causes the RTC and the synchrophasor clock to free-run until the clock is
