1. M-Bus interface

The M-BUS Interface (1 module wide, DIN rail mount) is developed to connect the Energy Counter to M-BUS. The interface receives the measurement data from the Energy Counter using infrared port available on the side of the counter, and gets the power supply from the bus.

1.1 Overview

M-BUS Interface complying with EN13757-2 and EN13757-3• Circuiting by means of drilled two-wires cables• 2 screw clamps on M-BUS Interface• Current consumption of M-BUS Interface: • ≤ 4 mA. This corresponds to 3 standard loads. The data transmission speed is selectable between 300, 600, 1200, 2400, 4800, 9600, 115200 and 38400 baud• The default speed is 2400 baud• The default Primary Address is 000•

2. Telegram formats

The telegram formats are three, identiﬁed by the ﬁrst character.

Byte Single character (HEX) Short Telegram (HEX) Long Telegram (HEX)

1 E5 10 68

2 C Field L Field

3 A Field L Field (Ripetition)

4 CS (Checksum) 68

5 16 C Field

6 A Field

7 CI Field

8 - YY Data (0 – 246 Bytes)

YY + 1 CS (Checksum)

YY + 2 16

Table 2.1 – The M-BUS Telegram Formats

Single Character• : This telegram format consists of the single character E5h and is used to acknowledge the telegram received. Short Telegram• : This telegram is identiﬁed by the start character 10h and consists of ﬁve character. It’s used by the M-BUS Master to command the transmission of data from the M-BUS Slave. Long Telegram• : This telegram is identiﬁed by the start character 68h and consists of a variable number of characters, in which are present also the active data. It’s used by the M-BUS Master to transmits commands to the M-BUS Slave, and by the M-BUS Slave to send the read-out Data from the M-BUS Master.

2.1 Telegram ﬁelds

The telegram ﬁelds (C, A, CI Fields, L and CS) have a ﬁxed length of one byte (8 bit) and serve predetermined effects in the M-BUS communication. The L Field deﬁnes the number of bytes of the active data.

10 M-Bus communication protocol

English

2.1.1 C FIELD

The Control Field (C Field) contains information on the direction of the exchange of communication, the success of the actual operation of communication and the proper function of the telegram.

Bit Number 7 6 5 4 3 2 1 0

Master > Slave 0 1 FCB FCV F3 F2 F1 F0

Slave > Master 0 0 ACD DFC F3 F2 F1 F0

Table 2.2 – C Field Bit Division

The Bit Nr 6 is set to 1 if the communication has the direction Master > Slave; viceversa it is set to 0. In the Master > Slave direction, if the frame count bit valid (FCV - Bit Nr 4) is set to 1, then the frame count bit (FCB – Bit Nr 5) has not to be ignored.

The FCB is used to indicate successful transmission procedure. A Master shall toggle the bit after a successful reception of a reply from the Slave. After this, if the Slave answer is multi-telegram, the Slave has to send the next telegram of the multi-telegram answer. If the expected reply is missing, or the reception faults, the master resends the same telegram with the same FCB. The Bits Nr 3 – 0 are the function code of the message. The C Field used here, are:

Telegram Name C Field (BIN) C Field (HEX) Telegram Description

SND_NKE 01000000 40 Short Frame Initialization of the Slave

SND_UD 01x10011 53 / 73 Long Frame Master send data to Slave

REQ_UD2 01x11011 5B / 7B Short Frame Master requests Class 2 Data to Slave

RSP_UD 000x1000 08 / 18 Long Frame Data transfer from Slave to Master

Table 2.3 – C Field of the commands used in this protocol

2.1.2 A FIELD

The Address Field (A Field) is used to address the recipient in the calling direction, and to identify the sender of information in the receiving direction. The size of this ﬁeld is one byte, and it can assume the value between 0 – 255, divided in this way:

A Field (HEX) Primary Address Remarks

00 0 Default Address Given by Manufacturer

01 – FA 1 – 250 Primary Address Settable

FB, FC 251, 252 Reserved for Future Use

FD 253 Used for Secondary Address Procedures

FE 254 Use to Transmit Information to All Partecipants in the M-BUS System

FF 255 Use to Transmit Information to All Partecipants in the M-BUS System

Table 2.4 – Value of Address Field

Using the address 254 (FEh) every Slave answer with the acknowledging (E5h) or with their primary address. Using the address 255 (FFh) no one Slave replies.

2.1.3 CI FIELD

The Control Information (CI Field) contains information for the receiver of the telegram. The CI Field values used here, are:

CI Field (HEX) Primary Address

51 The telegram contains data for the Slave

52 Selection of the Slave

72 The telegram contains data for the Master

B8 Set Baud Rate to 300 bps

B9 Set Baud Rate to 600 bps

Table 2.5 – Value of CI Field

2.1.4 L FIELD

The Length Field (L Field) deﬁnes the number of bytes (expressed in hex value) of the Active Data making up the telegram, plus 3 byte for the C, A and Cl Fields. This ﬁeld is always transmitted twice in Long Telegrams.

2.1.5 CS FIELD (CHECKSUM)

The Checksum (CS Field) serves to recognize transmission and synchronization faults, and is conﬁgured from speciﬁc parts of telegram. The checksum is calculated from the arithmetical sum of the data mentioned above plus the Active Data, i.e. from C Field to CS Field (excluded).

2.2 Active data

The Active Data (0 – 246 bytes) in Long Telegrams include the data to be read from the M-BUS Master (Read-Out Data), or Command Information transmitted by the Master to the Slave.

2.2.1 CODING OF ACTIVE DATA TRANSMITTED FROM SLAVE TO MASTER: FIXED DATA RECORD HEADER

Each block of Active Data transmitted by the Slave to the Master starts with the following Fixed Data Record Header (FDH):

Byte Nr. Size (Byte) Value (Hex) Description

1 – 4 4 xx xx xx xx M-BUS Interface Identiﬁcation Number

5 – 6 2 xx xx Manufacturer’s ID

7 1 xx Version Number of M-BUS Interface Firmware (00 – FF)

8 1 02 Medium: Electricity

9 1 xx Access Number (00 – FF > 00)

10 1 xx

M-BUS Interface Status (00 = Energy Counter Unreachable, 01 = Energy Counter Reachable)

11 – 12 2 0000 Signature (always 0000, i.e. not used)

Table 2.6 – Fixed Data Record Header

The Identiﬁcation Number is a changeable number by the customer and runs from 00000000 to 99999999. The Access Number has unsigned binary coding, and is incremented (modulo 256) by one after each RSP_UD from the Slave.

2.2.2 CODING OF ACTIVE DATA TRANSMITTED FROM SLAVE TO MASTER: DATA RECORDS

Every Data Record sent by Slave to the Master consist of the following Data Record Header (DRH) :

3.1 Send / conﬁrm procedure

3.1.1 SND_NKE

This procedure serve to start up after an interruption or beginning of communication. If the Slave was selected for secondary addressing, it will be deselected. The value of the frame count bit FCB is cleared in the Slave, i.e. it expects that the ﬁrst telegram from a Master with FCV = 1, has the FCB = 1. The Slave conﬁrms a correct reception of the telegram with the single character acknowledge (E5h) or omits the answer if it didn’t receive the telegram correctly. Here follows the structure of SND_NKE command:

3.1.2.3 Set Baud Rate

This action allows to change the Baud Rate of the M-BUS Slave. The Slave answers with single character acknowledgement (E5h) in the old baud rate. As soon as the ACK is transmitted, the Slave switches to the new baud rate. To make sure that the Slave has properly changed its baud rate, the Master, within 2 minutes has to send a command to the Slave in the new baud rate. If the Slave doesn’t send the ACK after x retry, the Master has to return to the old baud rate. Here follows the command, using the Primary Address of the Slave:

ANNEX A

In case of single-frame RSP_UD answer from the Slave, the communication process is the following:

MASTER SLAVE

SND_NKE > E5h

SND_UD > E5h

REQ_UD2 with C Field = 7Bh > RSP_UD with C Field = 08h DIF = 0Fh as last data block i.e. FCB = 1 & FCV = 1

This means that, if the FCB is handled (i.e. FCV = 1), when the RSP_UD answer has a single-frame of data, the Slave has to send a RSP_UD answer with the last data block egual to 0F.

In case of multi-frame RSP_UD answer from the Slave (for example 2 frames), the communication process is the following:

MASTER SLAVE

SND_NKE > E5h

SND_UD > E5h

REQ_UD2 with C Field = 7Bh > RSP_UD with C Field = 18h i.e. DFC = 1 DIF = 1Fh as last data block i.e. FCB = 1 & FCV = 1

REQ_UD2 with C Field = 5B > RSP_UD with C Field = 08 i.e. DFC = 0 DIF = 0Fh as last data block i.e. FCB = 0 & FCV = 1

This means that, if the FCB is handled (i.e. FCV = 1), when the RSP_UD answer has a single-frame of data, the Slave has to send a RSP_UD answer with the last data block egual to 0F.
