Modbus User Map; Real-Time Clock - GE b30 Instruction Manual

PRODUCT SETUP
Each command is identified by the unique combination made by the function type (FUN) and information number (INF). If
the master sends an ASDU command that does not have the FUN and INF of any configured command, the relay rejects it.

5.3.5 Modbus user map

SETTINGS  PRODUCT SETUP  MODBUS USER MAP
 MODBUS USER MAP

The Modbus user map provides read-only access for up to 256 registers. To obtain a memory map value, enter the address
in the line (converted from hex to decimal format). The corresponding value (if programmed) displays in the
ADDRESS
line. A value of "0" in subsequent register
5
incremented by 1. An address value of "0" in the initial register means "none" and values of "0" display for all registers.

SETTINGS  PRODUCT SETUP  REAL TIME CLOCK
 REAL TIME
 CLOCK
The relay contains a real time clock (RTC) to create time stamps 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 synchronizing
