|Many parameters and their settings are depend-

ent on the settings you have already made for oth-

er parameters. This means that some parameters

will appear or disappear and the values available

for selection will change according to settings you

have already made. These dependencies have

not been shown in the table for reasons of clarity.

All settings are always shown.

|Configurable times are set via the base and factor

parameters. The actual time is given by the multi-

plication of the two values. Example:

Base = 1 second, Factor = 3

Actual time = 3 seconds

|The bold values in a table are the values set dur-

ing factory configuration.

Table of contents

The KNX Metering Gateway is a device which connects

meters via the Modbus open standard to KNX. The

Modbus open standard allows you to receive a more in-

depth analysis of consumption in all areas of your build-

ing.

You can connect up to 10 of the following types of me-

ters based on Modbus remote terminal unit (RTU):

• Schneider Electric energy meters

• Schneider Electric power meters

• Schneider Electric Smart Interface Modules (SIM10M

module)

• Non-Schneider Electric Modbus RTU devices (offer-

ing you greater flexibility)

With the information which the KNX Metering Gateway

provides you can visualise energy or media consump-

tion. This can also be used to reduce consumption

through the use of control strategies within the KNX net-

work.

You can choose from 17 different pre-prepared tem-

plates for the meters and devices in order to quickly

connect to a KNX network. Each template contains the

20 most frequently needed Modbus values for simple

configuration.

From each connected Modbus RTU device the KNX

Metering Gateway can read up to an additional 40 Mod-

bus register values and transfer this data to the KNX

network.

You can read up to 10 meters using one KNX Metering

gateway. This makes the Gateway very cost-efficient.

Integrating a SIM10 module makes it possible to deter-

mine and visualise gas and water consumption.

The KNX Metering Gateway is also suitable for retrofit-

ting or for retroactive connection of existing Modbus

systems to KNX because it is fully compatible with me-

ters from other manufacturers.

The application is influenced by the following events:

•ETS download

• Bus voltage failure

•Bus voltage recovery

The behaviour differs according to function and can in-

fluence the measuring and monitoring function. There-

fore, you can set the behaviour using parameters at the

corresponding point. Refer to the chapter in question

for a precise description.

Function overview

Behaviour of the application

Metering Gateway Modbus REG-K

MTN6503-0201

Modbus settings

The gateway always works in master mode and the

connected Modbus devices work in slave mode. Com-

munication from KNX bus to the Modbus is not possi-

ble.

Baudrate setting

The Baudrate is set depending on the distance be-

tween Modbus RTU devices. For instance with a Baud

rate of 9,600 bit/sec the maximum communication dis-

tance between 1 - 15 Modbus RTU devices is 1,200

metres. With the Baud rate of 19,200 bit/sec the maxi-

mum communication distance is 900 metres, as the ta-

ble shows below:

Parity refers to the technique of checking if transmis-

sion has been successful when transmitting between

devices. It lets you know if some data has been lost dur-

ing transmission.

Setting of parity

The Modbus supports only 11 bit frames. The ETS ap-

plication sets stop bits automatically depending on the

parity setting. "Parity" refers to the number of 1s in a giv-

en binary number. Odd parity means there are an odd

number of 1s and even parity means that there are an

even number of 1s. Parity bits are used as a means of

error detection as digital data is transmitted and re-

ceived. Both the Gateway and Meter must always be set

to the same as one another, odd, even or none. The de-

fault parity mode of Modbus is "even" parity.

|Make sure that all connected meters are always

set to the same parity as one another, odd, even or

one.

• Parity = None: choose between one and two stop bits

• Parity = Even: one stop bit is set

• Parity = Odd: one stop bit is set

|When parity is set to „None“ it is necessary to pre-

set meters PM2x0, PM7x0 and PM8x0 to one stop

bit (all other meters require a setting of two stop

bits here). This means that under „None“ parity

PM2x0, Pm7x0 and PM8x0 meters cannot be

combined with other meters. In their case it is nec-

essary to work with „Odd“ or „Even“ parity.

Parameters

Delay between frames

Some devices require considerable time after end of re-

sponse until they are ready to receive the following re-

quest from the master. In particular Schneider Electric

SEPAM power devices and legacy slave devices. As

they are slow in dealing with the original request they

may miss the following request.

The time between requests should be less than 3.5

characters according to the Modbus specification.

However, these legacy devices need more time. The

parameter „Delay between frames“ solves this problem.

The time is automatically adapted to 3.5 characters of

the transmission speed, but you have the choice to in-

crease this time if you need to support such slow legacy

devices.

Parameters

Start-up delay

The parameter „Start-up delay“ specifies from what

point measured values are counted in the application.

After an ETS download or bus voltage recovery, the de-

vice starts measuring the connected channels when

the start-up delay is complete.

Metering device templates

Pre-installed ETS templates provide you with the 20

most frequently needed values which makes configura-

tion much easier and quicker. This also means there is

no need to map the Modbus register addresses to KNX.

The ETS application has special templates which you

use to implement the Schneider Electric Modbus RTU

based energy or power meters and SIM10M module.

These devices are outlined in the table below:

Metering device x

You can select the metering device you require from the

parameter „Type of metering device“. These are the 17

devices from the previous table.

Each connected device has a unique address, between

1 and 247, as per the Modbus addressing protocol. To

identify the device, you need to set its address at the

parameter „Address of metering device“.

The template allows you to to monitor different kinds of

values. To achieve this it has three monitoring functions

which you can enable by parameter. These are:

• „Voltage and current monitor“

• „Power monitor“

• „Consumption monitor“

With the parameter „Sending behaviour“ you can spec-

ify how all values of the monitors are sent. For a cyclical

sending, you can set the parameter „Time base“ to ei-

ther 1 second or 1 minute. The chosen setting applies

to all values of the whole template.

Consumption monitor

With the consumption monitor you can enable the fol-

lowing:

• Active energy counter (total energy - active in kWh)

• Reactive energy counter (total energy - reactive - in

kVArh)

• Apparent energy counter (total energy - apparent - in

kVAh)

These monitor energy consumption within the period.

You can then set their cyclic sending with integers of 1

second or 1 minute, with a base as configured in the

previous parameter „Time base“.

The energy counters each have 3 possible consump-

tion object types which you can set to Active energy,

Active energy kWh or Active energy V64.

Parameters

Application Example

Requirements

• measure and visualise how much energy is used

lighting an office building

• measure the gas and water consumption in the build-

ing

• monitor the quality of the network to ensure the oper-

ational safety of IT equipment

Solution

• install an iEM3150 meter to record the energy con-

sumed by the lighting

• install an iEM3255 meter to determine the network

quality

• install a SIM10M module to measure gas and water

consumption via impulse

• connect the devices to each other via Modbus

By connecting the KNX Metering Gateway to the Mod-

bus line, the data can be configured easily using the

templates supplied and then transmitted to the KNX

bus. The consumption data is then conveniently dis-

played for facility management in their offices on a

touch panel. Incoming alarms triggered by fluctuations

in the network quality are also displayed.

Template for SIM10M

Within the KNX Metering Gateway you can also connect

to a SIM10M module allowing you to:

• read energy consumption

• read the buildings‘ pulse meters that measure gas

and water consumption

• visualise these values

The SIM10M module offers you two different functions:

1. six logic counters with pulse acquisition and on/off

detection by internal 3.6 V DC power and pull-up resis-

tors.

2. two analogue inputs with a range of 0-10 V DC exter-

nally powered.

The SIM10M module is able to control and count the

pulses of up to six simple meters with pulse or relay out-

put.

The binary counters each have a scale, multiple and di-

vide factor implemented. This is because the ETS ap-

plication does not support decimal points, so in each

case there needs to be a multiple and divide factor to

achieve the required value, e.g. when scale factor =

18.32, multiple factor is 1832 and divide factor is 100.

Typical use case of SIM10M module and setting of

ETS application

When connecting the SIM10M module and the power

and pulse meters, you must set the amount of pulses

which are defined for 1kWh (or m3 for gas and water).

Those constants are set in the ETS application (preset

to 3,200 pulses and 1,000 imp/kWh). The result is sent

to the KNX bus via the communication object.

Reset of binary counter

The reset datapoint reacts only to a „true“ telegram. A

“false“ telegram is ignored.

Metering Gateway Modbus REG-K

MTN6503-0201

Direct access to Modbus register

The KNX Metering Gateway is only able to read basic

Modbus register values. For access to other Modbus

registers you must use an additional functionality, „Ac-

cess to Register x“. Within this parameter you can se-

lect which registers you wish to access. The registers

are grouped in five groups with eight registers each.

Access to Modbus register x

By enabling or disabling groups of registers, you can

then disable or enable access to individual registers.

Modbus register x

You can set parameter „Register type“ to either „Read

holding register“ (set as default) or „Read input regis-

ter“.

With the Read input register you can read from 1 to 125

contiguous input registers in a remote device. The Re-

quest protocol date unit (PDU) specifies the starting

PDU addresses start from zero, therefore registers

numbered 1 - 16 are addressed as 0 - 15.

You can set parameter „Modbus data is“ to Unsigned, to

Float or to Float (words are swapped).

You can set the Modbus value to convert to 2, 4 or 8

Byte. Within this datapoint the object type can be set to

„unsigned“, „signed“ or „float“. You must be careful

when setting the Modbus value as each datapoint has

a set range. If the value falls out of this range the send-

ing of the value will be blocked and will not reach the

KNX bus.

Diagnostic block

The Metering Gateway supports two different communi-

cation objects for the diagnostics of modbus devices.

These are „Active Modbus status“ and „Passive Mod-

bus status“.

The „Active Modbus status“ object sends an error code

to the KNX bus after recognising that a problem exists

on the Modbus. The sending of this status is controlled

by the parameter „Sending behaviour“. The status will

either be sent every time after reading of register (mini-

mum 20 times per device template) or it will only be sent

if Modbus exception code is changed. The range of ex-

ception codes is 0 - 6. All information about errors is

stored in external FRAM memory.

The last reported status of a slave can be forced to be

sent by the "Active Modbus status" object by sending

the slave ID to the "Passive Modbus status object.

When you enable the parameter „Reset“, a reset tele-

gram is sent and the gateway will stop reading all Mod-

bus registers and make a restart. If the parameter

"Reset" is enabled it is possible to restart the gateway

with a "1"-telegram on object "Reset of gateway".

The table of error codes is listed below:

Excep-

tion

code

Name Description

0 hex No error

(slave is ok)

01 hex Illegal

function

The function code received in the query is

not an allowable action for the slave. This

may be because the function code is only

applicable to newer devices, and was not im-

plemented in the unit selected.

It could also indicate that the slave is in the

wrong state to process a request of this type,

for example because it is unconfigured and

is being asked to return register values, If a

Poll Program Complete command was is-

sued, this code indicates that no program

function proceeds

02 hex Illegal data

address

The data address received in the query is not

an allowable address for the slave. The com-

bination of reference number and transfer

length is invalid.

03 hex Illegal

data value

A value contained in the query data field is

not an allowable value for the slave. This in-

dicates a fault in the structure of remainder of

a complex request, e.g. that the implied

length is incorrect.

It specifically does NOT mean that a data

item submitted for storage in a register has a

value outside the expectation of the applica-

tion program since the Modbus protocol is

unaware of the significance of any particular

value of any particular register.

04 hex Slave de-

vice failure

An unrecoverable error occurred while the

slave was attempting to perform the request-

ed action.

05 hex Acknowl-

edge

Specialized use in conjunction with program-

ming commands.

The slave has accepted the request and is

processing it, but a long duration of time will

be needed for it to do so. This response is re-

turned to prevent a timeout error from occur-

ring in the master. The master can issue a

Poll Program Complete message to deter-

mine if programming is complete.

06 hex Slave de-

vice busy

Specialized use in conjunction with program-

ming commands. The slave is engaged in

processing a long-duration program com-

mand. The master should re-transmit the

message later when the slave is free.
