1 Introduction

This document provides operating, maintenance and installation instructions.The unit measures

and displays the characteristics of single phase two wires(1p2w)supply, including voltage(V),

current(A),power(W),frequency(Hz),power factor(PF),active energy(kWh).The non-displayed

parameters of imported and exported energy can be read via RS485 communication with

corresponding register.

The meter is self-power supplied when it’s connected with single phase two wires system,does

not need to input a auxiliary power supply.It’s directed connected,does not need to connect with

external current transformer(CT).Built-in interfaces provides pulse and RS485 Modbus RTU

outputs.

1.1 Unit Characteristics

The Unit can measure and display:

Voltage

Current

Power

Frequency

Power factor

Active energy

Two pulse output indicates real-time energy measurement. An RS485 output allows remote

monitoring from another display or a computer.

1.2 RS485 Serial –Modbus RTU

This uses an RS485 serial port with Modbus RTU protocol to provide a means of remotely

monitoring and controlling the Unit

1.3 Pulse output

This provides two pulse outputs,Pulse 1 is settable and can be setted into four different energy

output modes:

Mode 1 0.001kWh/imp(default)

Mode 2 0.01kWh/imp

Mode 3 0.1kWh/imp

Mode 4 1kWh/imp

Also,pulse 1 can be setted into three types pulse out modes.

Mode 1:Measures imported energy.Total energy=imported energy(default)

Mode 2:Measures imported energy and exported energy.

Total energy=imported energy+exported energy

Mode 3:Measures imported energy and exported energy.

Total energy=imported energy-exported energy

Pulse 2 is fixed as 1000imp/kwh and cannot be setted.

To enter set-up mode, pressing the button for 3 seconds, until the lcd display the -SET-

5.1 Set-up Entry Methods

After successfully enter the SET model,then the set-up can be realized via RS485 communication

with the correct Modbus Protocol.

The electrical interface is 2-wire RS485,via 2 screw terminal.Connection should be made using

twisted pair screened cable(Typically 22 gauge Belden 8761 or equivalent).A total maximum

length of 3900 feet(1200 meters) is allowed for the RS485 network.A maximum of 32 electrical

nodes can be connected,including the controller.The address of SDM120C smart meter can be set

to any value between 1 and 247.Broadcast mode(address 0)is not supported.

All data values in the SDM120C smart meter are transferred as 32 bit IEEE754 floating print

numbers,therefore each SDM120C smart meter value is transferred using two Modbus Protocol

registers.All register read requests and data write requests must specify and even number of

registers.Attempts to read/write and odd number of registers prompt the SDM120C smart meter

to return a Modbus Protocol exception message.

The Modbus Protocol establishes the format for the master's query by placing into it the device

address,a function code defining the requested action,any data to be sent,and an error checking

field.The slave's response message is also constructed using Modbus Protocol.

Modbus Protocol function code 04/03 is used to read data.

For example:

to request 01 04 00 00 00 02 CRC to read the voltage

to request 01 04 00 12 00 02 CRC to read apparent power

For example:

to request 01 10 00 14 00 02 04 40 00 00 00 CRC to set meter address as 02

(Hex 40 00 00 00 equals float 2)

to request 01 10 00 1C 00 02 04 40 00 00 00 CRC to set baud rate as 9600

(Hex 40 00 00 00 equals float 2)
