Introduction

Description

The standard dataset is a global entity that collects the most useful information of each IMU module in one convenient table.

The benefit is that the full standard dataset can be read with only three read requests. Each module moves the data on a regular basis to the IFM interface. The IMU will answer faster to the Modbus command.

The standard dataset is defined in the 32000 to 32341 register range.

Table of Standard Dataset Common Registers

The main information required for remote supervision of an EasyPact MVS circuit breaker is contained in the table of common registers starting at register 32000.

One Modbus read request is limited to 125 registers maximum. Three Modbus read requests are necessary to read the entire table.

It contains the following information:

• Circuit breaker status

• Tripping causes

• Real-time values of main measurements: current, voltage, power, and energy

The content of this table of registers is detailed in Standard Dataset Common Registers (refer to Standard Dataset Common Registers).

It is recommended to use these common registers to optimize the response times and simplify the use of data.

Measurement Update Period

The update period for the common registers of the standard dataset is:

• One second for the following measurements:

  • Voltage

  • Current

  • Active and reactive power

  • Power factor

• Five seconds for the following measurements:

  • Energy

  • Minimum and maximum real-time measurement values
