This setting enables/disables the USB port on the graphical front panel. When the port function is "Enabled," a standard
USB serial cable allows a computer running the EnerVista UR Setup software to retrieve, display, and write settings either
individually or collectively, to display status and actual values, to initiate controls, and to retrieve and display event records,
oscillography records, data logger records, and disturbance records. Installation of the EnerVista software automatically
installs the drivers required to use this USB port.
DNP is not available using the USB port on the graphical front panel.
5.3.6 Modbus user map
SETTINGS
PRODUCT SETUP
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
ADDRESS
line (converted from hex to decimal format). The corresponding value (if programmed) displays in the
VALUE
line. A value of “0” in subsequent register
ADDRESS
lines automatically returns values for the previous
ADDRESS
lines
incremented by 1. An address value of “0” in the initial register means “none” and values of “0” display for all registers.
Different
ADDRESS
values can be entered as required in any of the register positions.
The UR Family Communications Guide outlines the Modbus memory map. The map is also viewable in a web browser;
enter the IP address of the N60 in a web browser and click the option.

PRODUCT SETUP
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
This setting applies to the USB port on the graphical front panel.
