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:

– A Modbus Master to control the 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.

Characteristics of the bus connection

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

– Repeaters

– 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.

Parameter RS-485/EIA485

Number of receivers 32

Maximum line length 1200 m

Common-mode input voltage -7 to +12 V

Input resistance of the receiver 12 kOhm

Input sensitivity of the receiver +/- 200 mV

Differential data transmission Yes



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:

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.

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.

1 2 3 4



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.

General form of a Modbus telegram

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.

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.

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

Error code 1 byte 0x83

Exception code 1 byte 01 or 02 or 03 or 04


Starting address 2 byte 0x0000 to 0xFFFF

Number of registers 2 byte 0x0001 to 0x007B

Byte count 1 byte (2 * number of registers) bytes

Register value (2 * number of registers) bytes

Subfunction 2 byte 0x0000 to 0xFFFF

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

Error code 1 byte 0x90

Exception code 1 byte 01 or 02 or 03 or 04



– 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.

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.

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 too long.

03 ILLEGAL_DATA_VALUEThe Master is attempting to write to a register that allows only read access. The value appearing in the data field is not permissible: e.g., range limits 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.

The following chapters describe the installation and configuration of the Dräger Polytron® 8000 gas detector with Modbus RTU interface (hereafter referred to as "gas detector").

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.

Commissioning

4 Commissioning

4.1 Checking installation and operation

Check the connections and cables for correct wiring prior to commissioning. Faulty connections can damage the gas detector.

Check the following prior to commissioning:

1. Are all cables connected properly?

2. Is voltage in the range from 10 to 30 V applied?

4.2 Configuring the RS-485 interface

The following settings are preset for the Modbus RTU transmission.

4.2.1 Assigning the gas detector’s address

Each Modbus device must have an address assigned to it. The gas detector is only detected by the control system if the set address is correct.Valid addresses lie within the range from 0 to 126. The gas detector is factory-set to address 126.Observe the following when configuring the gas detector:

1. Only assign each address once in a Modbus control system.

2. Use the factory-set address 126 for the functional test of the gas detector and in a Modbus control system that is in operation. To add further devices, subsequently change the address.

The gas detector’s address can be set using the DIP switch (hardware address assignment) or the menu (software address assignment). DIP switch 8 is used to set whether the hardware or software address assignment is active.

4.2.1.1 Dependency between hardware and software address assignment

The following dependencies exist when changing the address on a gas detector.

– Preconditions: Hardware address assignment is selected.If the hardware address assignment is changed, the gas detector must be turned off and back on again (power cycle) for the change of address to take effect.

– If the software address assignment is changed, the new address becomes valid immediately. The new address also remains valid if the hardware address assignment is activated and another address is set on the DIP switch. To validate the address set on the DIP switch, the gas detector must be turned off and back on again (power cycle).

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.

5.1.1 Serial reading and writing

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

Parameters can only be read or written into individually. Addressing multiple parameters at the same time is not possible.

Parameters can be assigned to multiple registers. In the request, the number of registers addressed has to match the number of registers of the desired parameter. If too few or too many registers are requested from the gas detector, the gas detector answers with Illegal Data Address. An overview of the number of parameter registers can be found in the Modbus protocol description in the annex to this document.

Examples

If the parameter is only 1 register long (e.g., DEVICE_STATE), only this register can be addressed.

If the parameter is 10 registers long (e.g., DEVICE_STATUS_VALUE), only these 10 registers can be addressed.

5.1.2 Passwords

Certain functions are password-protected.

The default values consist of 3 underscores ((_), ASCII character set position 95 (decimal) or 0x5F (hexadecimal)) and a digit (1 or 2).

Passwords can consist of the following characters:

– A-Z (uppercase only)

– 0-9

– Blank spaces

– "-"

– "/"

– "_"

Calibration PWD Access to information (information menu) and calibration settings (calibration menu)Default value: _ _ _ 1

Settings PWD Access to all configurations and menusDefault value: _ _ _ 2



Changing passwords

There are 2 parameters for changing passwords. Both parameters are 4 registers long. In the first two registers, the current password is requested, and in the other two registers, the new password is set.

Checking the password changes

The PASSWORD_STATUS parameter can be used to check whether the passwords were changed successfully. The parameter is one register long (register 40709) and can assume the following values.

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.

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.

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.
