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
line (converted from hex to decimal format). The corresponding value displays 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
values can be entered as required in any of the register positions.

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
