Modbus communication overview

Modbus RTU protocol is available on iEM3150 / iEM3155 / iEM3250 / iEM3255 / iEM3350 / iEM3355 meter models.

The information in this section assumes that you have an advanced understanding of Modbus communications, your communications network and the power system that your meter is connected to.

There are three different ways of using Modbus communication:

• By sending commands using the command interface

• By reading the Modbus registers

• By reading Device Identification

Modbus communications settings

Before communicating with the device using Modbus protocol, use the display to configure the following settings:

Energy and energy by tariff measurements

Most energy values are available in both signed 32-bit integer and floating point format. The SNVT is appended with _l for 32-bit integer values and _f for floating point values.

For example, the SNVTs for total active energy import are as follows:

• 32-bit integer: SNVT_elec_kwh_l

• Floating point: SNVT_elec_whr_f

Echelon LonMaker plug-in for data display and meter configuration

The information in this section assumes that you have an advanced understanding of system administration using Echelon LonMaker.

The LonMaker plug-in provides a graphical user interface where you can view meter values and configure meter settings. Once you install and register the plugin with LonMaker, it opens instead of the default LonMaker browser when you browse the meter in LonMaker.

To add devices to LonMaker, you need access to the device service pin when commissioning the device or your need the device Neuron ID recorded in an accessible location.

Installing and registering the LonMaker plug-in

Before you install the plug-in:

DOCA0005EN-13 61

Page 62

iEM3100 / iEM3200 / iEM3300 series Communications via LonWorks

• Download the plug-in and XIF file for your device from www.se.com or contact your sales representative to obtain these files.

• Make sure Echelon LonMaker is closed.

1. Navigate to the location where you saved the plug-in. Extract the files if they are in a .zip file.

2. Double-click setup.exe. A welcome screen appears. Click Next.

3. Select the installation folder where you want to install the plug-in. Click Browse if you want to select a different location. Click Next. A confirmation screen appears.

4. Click Next to begin the installation.

NOTE: If LonMaker is open, a message appears instructing you to close LonMaker and restart the plug-in installation.

A screen appears when the installation is complete. Click Close.

5. Navigate to Start > Programs > Schneider Electric and select the registration entry for the plug-in you installed (for example, Schneider Electric iEM3275 Plugin Registration). The LNS Plugin Registration dialog box appears, indicating that registration is complete.

Make sure that the plug-in appears in the list of registered plug-ins in LonMaker before you try to connect to a meter using the plug-in. If it does not appear, you may need to re-register the plug-in.

Once the plug-in is installed and registered, add the meter to LonMaker. You can either read the template (.XIF) from the device during commissioning or select the EnergyMeter5A or EnergyMeter63A template when you add the device to LonMaker.

Browsing the meter using the LonMaker plug-in

In order to use the plug-in to view data and configure the meter:

• The plug-in must be installed and registered.

• The meter must be added to LonMaker and commissioned.

1. Open LonMaker.

2. Right-click the meter icon and select Browse. The meter plug-in appears.

NOTE: If the meter-specific plug-in does not open, the plug-in may not be correctly registered or the meter may not be properly commissioned in LonMaker. Double-check the registration and meter commissioning. Refer to the Echelon LonMaker documentation for more information.

M-Bus protocol support

The meter supports the M-Bus protocol as follows:

• Mode 1 communications (least significant bit first).

• Telegram formats:

◦ Single character ◦ Short frame ◦ Long frame

• Function codes (C-field bits 3-0):

◦ SND_NKE: Initiates of communications between the master and slave. ◦ SND_UD: The master sends user data to the slave. ◦ REQ_UD2: The master requests Class 2 user data from the slave. ◦ RSP_UD: The slave sends requested data to the master.

• Secondary addressing in accordance with the M-Bus standard.

• Broadcast telegrams.

Power, energy and power factor

Power (PQS)

A typical AC electrical system load has both resistive and reactive (inductive or capacitive) components. Resistive loads consume real power (P) and reactive loads consume reactive power (Q).

Apparent power (S) is the vector sum of real power (P) and reactive power (Q):

Real power is measured in watt (W or kW), reactive power is measured in var (VAR or kVAR) and apparent power is measured in volt-amp (VA or kVA).

Power and the PQ coordinate system

The meter uses the values of real power (P) and reactive power (Q) on the PQ coordinate system to calculate apparent power.

Power flow

Positive power flow P(+) and Q(+) means power is flowing from the power source towards the load. Negative power flow P(-) and Q(-) means power is flowing from the load towards the power source.

The meter interprets energy delivered (imported) or received (exported) according to the direction of real power (P) flow.

Energy delivered (imported) means positive real power flow (+P) and energy received (exported) means negative real power flow (-P).
