MESSAGE
®
The Modbus User Map provides up to 256 registers with read only access. To obtain a value for a memory map address,
enter the desired location in the
ing value from the is displayed in the
values for the previous
ADDRESS
values of "0" will be displayed for all registers.
Different values can be entered as required in any of the register positions.

These settings can also be used with the DNP protocol. See the DNP ANALOG INPUT POINTS section in
Appendix E for details.

REAL TIME

CLOCK
The date and time for the relay clock can be synchronized to other relays using an IRIG-B signal. It has the same accuracy
as an electronic watch, approximately ±1 minute per month.
An IRIG-B signal may be connected to the relay to synchronize the clock to a known time base and to other relays. If an
IRIG-B signal is used, only the current year needs to be entered.

FAULT REPORT
„
MESSAGE
The fault report stores data, in non-volatile memory, pertinent to an event when triggered. The captured data will include:
• Name of the relay, programmed by the user
• Date and time of trigger
• Name of trigger (specific operand)
• Active setting group
• Pre-fault current and voltage phasors (one-quarter cycle before the trigger)
• Fault current and voltage phasors (three-quarter cycle after the trigger)
• Target Messages that are set at the time of triggering
• Events (9 before trigger and 7 after trigger)
The captured data also includes the fault type and the distance to the fault location, as well as the reclose shot number.
