Overview

This Intesis® gateway allows to integrate M-Bus devices into Modbus TCP systems easily.
The aim of this integration is to make M-Bus devices accessible from a Modbus control system or device to get the same behavior as if the M-Bus device was part of the Modbus installation.
For this, the Intesis gateway acts as a Modbus TCP server device in its Modbus interface, allowing it to read/write points from the Modbus client device(s). From the M-Bus point of view, the gateway acts as an M-Bus level converter and Master device (EN-1434-3). The gateway performs the readings of the M-Bus slave device(s) by automatic continuous polling or on demand (to reduce battery consumption).
The gateway configuration is carried out through the Intesis MAPS configuration tool.

VIKTIG
This document assumes that the user is familiar with Modbus and M-Bus technologies and their technical terms.

Flexible configuration using the Intesis MAPS configuration tool.

Gateway General Functionality

This gateway acts as a server on its Modbus side and as a master on its M-Bus interface, thus allowing the integration of M-Bus devices into a Modbus system.
The gateway is continuously polling the devices (together or individually), storing in its memory the current status of every signal you want to track, and serving this data to the installation when requested. This continuous polling can be activated/deactivated through a Modbus signal. It is also possible to configure the gateway to make a single polling of the meters (refresh of readings) at startup.
Primary or secondary addressing is allowed for M-Bus devices. When a signal status changes, the gateway sends a write telegram to the installation, waits for the response, and performs the corresponding action.

This action can be: force a polling of a specific M-Bus device or force a polling of all M-Bus devices. This can also be forced from the Modbus side at any time by writing a 1 in the corresponding binary point specially enabled for this purpose.

Other M-Bus information accessible from Modbus, using specific points of the gateway, is:

Bus activity: Indicates if meters are currently being polled or polling is on standby.

M-Bus status of every meter: This is sent by the own meter with every poll and indicates the internal status, which is manufacturer specific in every case.

A lack of response from a signal activates a communication error, allowing you to know which signal from which M-Bus device is not correctly working. There is also a general communication error available that will be active whenever the communication with one or more M-Bus meters has failed.

Montering

VIKTIG
Før montering, sørg for at det valgte installasjonsstedet beskytter porten mot direkte solstråling, vann, høy relativ fuktighet eller støv.
NOTE
Mount the gateway on a wall or over a DIN rail. We recommend the DIN rail mounting option, preferably inside a grounded metallic industrial cabinet.
VIKTIG
Sørg for at gatewayen har tilstrekkelige klaringer for alle tilkoblinger når den er montert. Se Dimensjoner (side 13).

DIN-SKINNEMONTERING

Fit the gateway’s top-side clip in the upper edge of the DIN rail.
Press the low side of the gateway gently to lock it in the DIN rail.

Make sure the gateway is firmly fixed.

NOTE
For some DIN rails, to complete step 2, you may need a small screwdriver or similar to pull the bottom clip down.

VEGGMONTERING

VIKTIG
For reasons of security, the maximum height for wall mounting is two meters (6.5 feet).

Press the rear panel clips outwards until you hear a click.

M-Bus System

Generell beskrivelse
The M-Bus (“Meter-Bus”) is a European standard for remote reading of heat meters, and it is also usable for all other types of consumption meters, as well as for various sensors and actuators.

M-Bus standards are:

EN 13757-2 (physical and link layer – Wired M-Bus)

EN 13757-3 (application layer)

Many manufacturers of energy meters, pulse counters, water meters, electricity meters, etc., add an M-Bus interface to their devices, enabling them to be interconnected and remotely monitored through a 2-wire bus based on the M-Bus standards. There are many manufacturers of these measurement devices incorporating the M-Bus interface, and also some other manufacturers of specific M-Bus communication devices such as bus repeaters, EIA-232/EIA-485 to M-Bus level converters, etc.

M-Bus Interface

The gateway connects directly to the M-Bus system. No external level converter is required.
Connection to the M-Bus is made via the EIA-485 connection. Notice that the gateway also powers the bus, so no extra hardware is required to connect to M-Bus compatible meters or devices.

M-Bus Signals
The gateway supports several meter magnitudes and units typically used on energy, electricity, water, and other meters. This information is required to add the desired signals when integrating meters manually, as this process is done through the Intesis MAPS configuration tool by setting the meters up and then adding the signals each meter uses and assigning them accordingly in the Signals tab (page 20).

MERKNAD

The type of signals available from each meter may differ depending on the manufacturer and model, so please refer to the device’s technical documentation to determine the signals available for a given meter when adding meters manually.
However, Intesis MAPS also offers a much quicker and simpler alternative method for meter detection in the form of a scanning function. This scan detects all meters available on the bus and their signals and imports each signal with the units and details each meter provides. These signals can then be matched with the corresponding Modbus registers in the Signals tab for integration with the BMS.

Modbus System

Generell beskrivelse

The Modbus protocol is an application-layer messaging protocol developed by Modicon in 1979. It is used to establish client-server communication between intelligent devices over different types of buses or networks. The Intesis gateway supports Modbus TCP.
Modbus is a request/reply protocol and offers services specified by function codes. Modbus function codes are elements of Modbus request/reply PDUs (Protocol Data Units).

ModBus Interface
The Intesis gateway acts as a server device in its Modbus interface; the interface for this model is the Ethernet port. To access the points and resources of the gateway from a Modbus client device, you must specify the Modbus register addresses configured inside the gateway as those configured inside the gateway corresponding to the signals of the field device protocol.

Modbus-feilkoder støttes fullt ut. De sendes når det kreves en ugyldig Modbus-handling eller adresse.

ModBus TCP

Modbus TCP-kommunikasjon kjennetegnes i hovedsak av innbygging av Modbus RTU-protokollen i TCP/IP-rammer, som tillater raskere kommunikasjon og lengre avstand mellom klient- og serverenheter sammenlignet med RTU-kommunikasjon over en seriell linje. En annen fordel er bruk av vanlig TCP/IP-infrastruktur i bygninger og overføring over WAN eller internett. Den tillater også sameksistens av én eller flere klienter og, selvfølgelig, én eller flere serverenheter i et gitt nettverk, alle sammenkoblet gjennom et TCP/IP-basert nettverk.
Bruk konfigurasjonsverktøyet til å konfigurere IP-innstillingene til gatewayen (DHCP-status, egen IP, nettmaske og standard gateway) og TCP-porten.

Default value. The measurement-related registers can be configured to be 4 or 8 bytes (32 or 64 bits) in Intesis MAPS if required.
