Time-Stamped Information - Compact NSX Modbus Comm Guide

General Description

The time-stamped information enables the user to know all the dates relative to important information such as previous protection settings and minimum/maximum values of currents, voltages, and system frequency.

The time-stamped information table describes:

the previous protection setup parameters and corresponding dates
the minimum and maximum values of voltage measurements and corresponding dates
the maximum values of current measurements and corresponding dates
the minimum and maximum system frequencies and corresponding dates
the peak demand of current and power and corresponding dates

A read request of 100 registers is necessary to read the time-stamped previous protection registers (29600–29699).
