Basic principles of the Modbus technology

2 Basic principles of the Modbus technology

2.1 Definition of the Modbus protocol

The Modbus protocol was developed by Modicon in 1979. It is an open, standardized communications protocol which is used in production, process, or building automation.

Modbus is a protocol for transmitting messages between electronic devices. The device requesting the information is the Modbus master. The devices sending the information are the so-called slaves. There are one master and up to 247 slaves in a standard Modbus network. Each slave is defined by its own address from 1 to 247.

Modbus RTU (Remote Terminal Unit) is a binary transmission protocol for serial interfaces (RS-232 or RS-485). The original system was developed with a RS-232 interface. However, it was adapted for RS-485 interfaces for faster transmission rates. In addition, the RS-485 interface is bus-compatible: multiple devices can be connected to the data cables.

For this product, only the RS-485 interface is described.

For further information on the Modbus technology, also see www.modbus.org.

For further information on RS-485, also see ANSI/TIA/EIA-485-A.

2.2 System overview

Modbus RTU is based on a master/slave architecture. In a master/slave system, the master communicates with one or more slaves. It is a mono-master system: only one master can be connected at any one time.

The slaves in a Modbus network cannot start communication. They can only respond.



2.2.1 Topology

Minimum configuration

A Modbus system consists of at least the following components:

– One Modbus master to control data traffic.

– One or more slaves which are available upon request of the master.

– The transmission medium, consisting of the bus cable and bus connector to connect the individual participants.

Maximum configuration

A bus segment consists of a maximum of 32 field devices (active and passive). The highest possible number of slaves that can be operated with one Modbus master across several segments is determined by the internal memory structure of the master.

The bus cable can be separated anywhere and a new participant added with a bus connector. At the end of a segment, the bus cable can be extended until the predetermined segment length is reached. The length of a bus segment depends on the set transmission speed. The transmission speed is primarily determined by the system constellation (length of a segment, distributed inputs/outputs) and the required scanning cycles of individual participants. The same transmission speed has to be selected for all participants connected to the bus.

Connect Modbus devices in a line structure.

If there are more than 32 participants, the Modbus system can be extended by connecting repeaters. This enables bridging longer distances than defined for the transmission speed.

2.2.2 Transmission technology

RS-485

RS-485 is the most common transmission technology. It uses a shielded, twisted 2-wire line. Transmission rates between 9600 bit/s and 115200 bit/s can be selected. It is defined when commissioning the system and is the same for all devices connected to the bus. Up to 32 bus participants can be connected per segment. The maximum permissible line length depends on the transmission rate.

Several different network topologies are possible:

– Backbone

– Star

– Ring

– Daisy chain



According to experience, a RS-485 network works best in a daisy chain topology. In this topology, reflections on the network line are absorbed most effectively.

2.3 Data transmission

There are 3 different data transmission modes in a Modbus system:

– Modbus ASCII

– Modbus RTU

– Modbus TCP

In Modbus ASCII, data is not transmitted as a binary sequence, but as ASCII code. The data is directly human-readable, but the data throughput is lower than in Modbus RTU.

Data transmission in Modbus RTU is in binary format. The binary format enables faster data transmission. However, the data needs to be converted to a readable format as it is not human-readable.

Modbus TCP is very similar to Modbus RTU. However, the data is transmitted in TCP/IP packets.

2.3.1 Modbus protocol structure

Communication in a Modbus network is structured in several layers according to the ISO/OSI model. To enable communication across a variety of technical systems, the individual layers have different tasks.

The Modbus protocol corresponds to layer 7 in the ISO/OSI model – the so-called application layer. It enables client/server communication between different devices that are connected via different buses or networks. The protocol defines a procedure for the exchange of information. It is therefore independent of the lower physical layers. For this reason, different implementations exist on different communication media:

– Ethernet

– Radio links

– Fiber optic cable

– Mobile radio

Application layer – layer 7

The application layer provides functions for the application. It forms the connection to the lower layers. Software for communication within the scope of the specific application (measuring system, etc.) is provided by the manufacturers. In addition, there are a number of terminal programs to enable communication between the participants in a Modbus network. The terminal programs (e.g., Modbus Poll) perform all functions of layers 5 to 7 for the user.

Physical layer – layer 1

The physical layer is the lowest layer and provides mechanical, electrical, and other functional tools for establishing connections. These connections are activated, deactivated, and used to transmit bits. These procedures serve to transmit, for example, electrical signals, optical signals, electromagnetic waves, or sound. Among others, the following devices and network components are assigned to the physical layer:

– Antenna

– Repeater

– Connector

– Socket for the network cable

– Hub

– Transceiver

– T-piece

– Terminator

Data transmission via Modbus RTU is digital, purely electrical, based on voltage levels. Normally, 9-pin connectors and sockets are used. The pin assignment is not standardized. Therefore always observe the manufacturer's documentation when using different devices.

Transmission rates

The transmission rate defines the speed at which data is transmitted. The transmission parameters have to be the same for all devices connected to a bus.

The following transmission rates are available for RS-485 applications:

Operating principle

Communication in a Modbus network follows a simple request/response mechanism: the master (1) sends a request (telegram) (2) to the slave (4). The function code contained in the telegram tells the slave which function to execute. The Modbus application protocol defines the format in which the request initiated by the master is sent.

There are 3 different communication cases:

1200 bit/s

2400 bit/s

4800 bit/s

9600 bit/s

19200 bit/s

38400 bit/s

56000 bit/s

115200 bit/s

31

1 Master

2 Request from master to slave

3 Slave response

4 Slave

The device (slave) receives a valid telegram with a valid request.

If it can answer this, it sends a response telegram with the function code of this request.

The device (slave) receives an invalid telegram (e.g., CRC error)

It does not answer. The application (master) has to correct the error within a defined time (timeout).

The device (slave) receives a valid telegram with an invalid request.

It answers with a Modbus exception code (excep-tion). The application (master) has to correct the error.

Communication

If a cable pair is used, transmission takes place in half-duplex mode: data can flow alternately in both directions, but not simultaneously.

If two cable pairs are used, full-duplex mode is also possible: data is transmitted in both directions at the same time.

Communication in the Modbus network occurs through so-called polling. The master sends a telegram (request) to the slave. It then receives the response.

Data transmission in Modbus RTU is in binary format. A data telegram consists of several blocks (frames).

– One address block (1 byte = 1 character)

– One function block (1 byte = 1 character)

– One data block (variable)

– One checksum block (CRC = cyclic redundancy check)

Between 2 telegrams there has to be a break with a length of at least 3.5 characters. The corresponding wait time depends on the transmission rate. If a transmission break of more than 1.5 characters occurs during telegram transmission, the transmission process is considered incomplete and should be aborted.

Address

The address specifies which device is contacted (master - slave) or which device responds. The address is a number between 1 and 126. The address 0 is used for messages to all devices (broadcast), provided that the selected function supports this.

The configuration of the address depends on the respective device and the system architecture.

Function code

The function code specifies the purpose of the data transmission. It defines the command to be executed by the slave.

Broadcast messages are only permitted with function codes 06, 16, and 23. Function code 08 is only supported for RS-485.

Data

The Data field contains the information to be transmitted. It is subdivided into registers, the number of registers to be transmitted, and, if necessary, information that has been read or has to be saved. Data is normally transmitted as a multiple of 16-bit registers.

Number of registers 2 bytes 1 to 123 (0x7B)

Error code 1 byte 0x90

Exception code 1 byte 01 or 02 or 03 or 04



Cyclic redundancy check - CRC (checksum)

The CRC is a 16-digit checksum calculated based on all bytes of a telegram. To be able to detect transmission errors, it is generated by the master and also calculated by the receiver. If the CRC value does not match the transmitted sum, the device will request the telegram to be transmitted again.

If the field device executes the requested function, it will send a response telegram to the master. The telegram contains the following parameters:

– Address of the device that was contacted and is now replying

– Function code

– The requested data

– CRC value

Modbus exception codes

If the slave detects an error in the request telegram from the master, it returns an error message to the master. The error message consists of the following elements:

– Slave address

– Function code

– Error code (exception code)

– CRC (checksum)

To mark the error message, the leading bit of the returned function code is set. The error code (exception code) is used to transmit the error cause to the master.

Excep-tion code

Description

01 ILLEGAL_FUNCTIONThe function code sent by the master is not supported by the slave.

02 ILLEGAL_DATA_ADDRESSThe register addressed by the master is not assigned (does not exist) or the length of the requested data is to long.

03 ILLEGAL_DATA_VALUEThe master attempts to write to a register that allows only write access. The value appearing in the data field is not permissible: e.g., range lim-its exceeded or wrong data format.

04 SLAVE_DEVICE_FAILUREThe slave did not respond to the request telegram from the master or an error occurred when processing the request telegram.



Addressing of the registers

* The register address is transmitted as a 16-bit word. The first register is assigned the address value 0.

Please note: another notation, where the register addresses are counted starting with 1, is also common in Modbus applications. In that case, this address (register address - 1) is transmitted in the Modbus telegram.

3.1 Technical data

The following values apply for the gas detector:

3.2 Cables

3.2.1 Cable type

Various cable types (type designations A to D) for different applications are available on the market to interconnect the devices and connect them to network elements (e.g., segment couplers, links, and repeaters). Use a type A cable for RS-485 transmission.

The maximum length of the cables that can be used in a Modbus system is determined by various factors. Different limitations apply for the cables and the individual leads.

Use shielded, twisted 2-wire cables and observe the maximum cable length.

Installation

3.2.2 Cable lengths

The following factors influence the cable length

– Transmission rate

– Cable type

– Number of directly connected devices (series connection)

– Network configuration (2-wire or 4-wire)

The maximum line length is 1000 m, at a transmission rate of 19200 bit/s. It depends on the data transmission speed and the number and lengths of the individual leads.

3.2.3 Increasing cable lengths with repeaters

Repeaters can be integrated in the system to extend the Modbus transmission cable. No more than 3 repeaters per system are permitted. The cable length can be extended by the factor 4, i.e., to max. 4000 m.

3.2.4 Grounding and shielding

Use a shielded twisted cable for connections via the RS-485 interface. To achieve a sufficient shielding effect, connect a large area of the shield at both ends of the cable to housing or cabinet parts.

Connect the shielding of the connector to protective ground in at least one point.

The legal EMC requirements are only met if the shielding is grounded at the control unit at one end.

The shield is capacitively connected to the grounding of the housing via pin 4 (shield) of the 4-pin connector.

Integration into process control systems

5 Integration into process control systems

5.1 General information

Gas detectors can be quickly and easily connected to process control systems via a digital Modbus RTU interface. They allow the cyclic capturing of measured values, status information and the full configuration of the gas detector in remote operation.

The Dräger Polytron 8000 gas detector with Modbus RTU interface supports function codes 03 Read Holding Registers and 16 Write Multiple Registers.

The following subsections present telegrams for reading and/or writing based on the corresponding key parameters of the gas detector.

5.2 Reading the gas concentration

The MEASUREMENT_MODE parameter indicates the current value of the gas concentration and can be read cyclically via the register address 40507. The parameter is read-only and is updated each second by the gas detector.

Register: 40507

Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit09 Bit08 Bit07 Bit06 Bit05 Bit04 Bit03 Bit02 Bit01 Bit00

MEASUREMENT_MODE.VALUE[3] MEASUREMENT_MODE.VALUE[2]

E.g.: MEASUREMENT_MODE.VALUE=40.00 (dec) / 0x42200000 (hex)

0x42 0x20

Register: 40508


MEASUREMENT_MODE.VALUE[1] MEASUREMENT_MODE.VALUE[0]

E.g.: MEASUREMENT_MODE.VALUE=40.00 (dec) / 0x42200000 (hex)

0x00 0x00



The corresponding telegram from the master for reading the MEASUREMENT_MODE parameter is shown in the following table. The parameter is read using the Modbus function code 0x03 - Read Holding Registers. In addition, the master needs the address of the gas detector and the register address for successful communication.

If the telegram has been transmitted without errors via the physical medium, the gas detector answers with the following telegram contents:

The Data telegram field contains the register contents, which can be analyzed or decoded as appropriate. The current target gas concentration is specified by the first 4 data bytes of the data field in data type FLOAT.

E.g.: MEASUREMENT_MODE.VALUE = 0x42200000 (hex)

or

MEASUREMENT_MODE.VALUE = 40.00 (dec)

5.3 Reading diagnostic and status information

The gas detector with Modbus RTU interface offers a large variety of options for capturing diagnostic and status information.

The following telegrams are examples to show how the status information in the DEVICE_STATUS_INDICATION (general overview of current errors and warnings) and DEVICE_STATUS_VALUE (detailed overview of current errors and warnings) parameters are read.

DEVICE_STATUS_INDICATION:

The DEVICE_STATUS_INDICATION parameter is read using function code 0x03 and is located in register 40023.

N.A. DEVICE_STATUS_INDICATION

E.g.: DEVICE_STATUS_INDICATION = 0x02

0x00 0x02



The corresponding telegram with the gas detector address 0x03 is shown below.

The gas detector sends the following response to the telegram. Take the value 0x0004 from the data field. Interpret the value accordingly based on the parameter description table in the annex. This example refers to a current warning of the gas detector.

The DEVICE_STATUS_INDICATION parameter provides a quick overview of the current status of the gas detector. For further information and possible remedies, read the DEVICE_STATUS_VALUE parameter in register 40024.

The parameter consists of 10 registers (20 bytes) and is read-only. The register range from 40024 to 40028 contains a warning matrix consisting of 10 bytes (W09 to W00).

The register range from 40029 to 40033 contains an error matrix (E09 to E00) consisting of 10 bytes.

Response of the gas detector:

Register 40025 contains the value 0x21. The value can be interpreted based on the error description.

It is a warning (W06) that the connected sensor is warming up and that the current measured value will be issued with an increased error. After completion of the warm-up phase, the warning disappears.

Troubleshooting

6 Troubleshooting

6.1 Error analysis

If communication with the gas detector cannot be established, check the settings of the following parameters:

– Address

– Port (COM port)

– Baud rate

– Parity

– Stop bits

– Termination

The parameters in the gas detector and in the communication DTM have to match to establish a connection.
