What is Modbus? 

Modbus is a serial communication protocol developed by Modicon published by Modicon® in 1979 for use with its programmable logic controllers (PLCs). In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Client and the devices supplying information are Modbus Servers. In a standard Modbus network, there is one Client and up to 247 Servers, each with a unique Server Address from 1 to 247. The Client can also write information to the Servers.

The official Modbus specification can be found at https://www.modbus.org/ 

What is it used for?

Modbus is an open protocol, meaning that it's free for manufacturers to build into their equipment without having to pay royalties. It has become a standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. It is used widely by many manufacturers throughout many industries. Modbus is typically used to transmit signals from instrumentation and control devices back to a main controller or data gathering system, for example a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Versions of the Modbus protocol exist for serial lines (Modbus RTU and Modbus ASCII) and for Ethernet (Modbus TCP).

How does it work?

Modbus is transmitted over serial lines between devices. The simplest setup would be a single serial cable connecting the serial ports on two devices, a Client and a Server. 


The data is sent as series of ones and zeroes called bits. Each bit is sent as a voltage. Zeroes are sent as positive voltages and a ones as negative. The bits are sent very quickly. A typical transmission speed is 9600 baud (bits per second).


What is hexadecimal?

When troubleshooting problems, it can be helpful to see the actual raw data being transmitted. Long strings of ones and zeroes are difficult to read, so the bits are combined and shown in hexadecimal. Each block of 4 bits is represented by one of the sixteen characters from 0 to F. 


Each block of 8 bits (called a byte) is represented by one of the 256 character pairs from 00 to FF. 

How is data stored in Standard Modbus?

Information is stored in the Server device in four different tables. Two tables store on/off discrete values (coils) and two store numerical values (registers). The coils and registers each have a read-only table and read-write table. Each table has 9999 values. Each coil or contact is 1 bit and assigned a data address between 0000 and 270E. Each register is 1 word = 16 bits = 2 bytes and also has data address between 0000 and 270E.


Coil/Register Numbers can be thought of as location names since they do not appear in the actual messages. The Data Addresses are used in the messages. For example, the first Holding Register, number 40001, has the Data Address 0000. The difference between these two values is the offset. Each table has a different offset. 1, 10001, 30001 and 40001. 

What is the Server ID?

Each server in a network is assigned a unique unit address from 1 to 247. When the client requests data, the first byte it sends is the Server address. This way each server knows after the first byte whether or not to ignore the message. 

What is a function code?

The second byte sent by the Client is the Function code. This number tells the server which table to access and whether to read from or write to the table.


What is a CRC?

CRC stands for Cyclic Redundancy check. It is two bytes added to the end of every modbus message for error detection. Every byte in the message is used to calculate the CRC. The receiving device also calculates the CRC and compares it to the CRC from the sending device. If even one bit in the message is received incorrectly, the CRCs will be different and an error will result. .

What are the formats of Modbus commands and responses? 


What are data types?

The example for FC03 shows that register 40108 contains AE41 which converts to the 16 bits 1010 1110 0100 0001 Great! But what does it mean? Well, it could mean a few things. Register 40108 could be defined as any of these 16-bit data types:

A 16-bit unsigned integer (a whole number between 0 and 65535) register 40108 contains AE41 = 44,609 (hex to decimal conversion) 

A 16-bit signed integer (a whole number between -32768 and 32767) AE41 = -20,927 (hex to decimal conversion that wraps, if its over 32767 then subtract 65536) 

A two character ASCII string (2 typed letters) AE41 = ® A 

A discrete on/off value (this works the same as 16-bit integers with a value of 0 or 1. The hex data would be 0000 or 0001) Register 40108 could also be combined with

40109 to form any of these 32-bit data types: 

A 32-bit unsigned integer (a number between 0 and 4,294,967,295) 40108,40109 = AE41 5652 = 2,923,517,522 

A 32-bit signed integer (a number between -2,147,483,648 and 2,147,483,647) AE41 5652 = -1,371,449,774 

A 32-bit double precision IEEE floating point number. This is a mathematical formula that allows any real number (a number with decimal points) to represented by 32 bits with an accuracy of about seven digits. AE41 5652 = -4.395978 E-11 Here is a spreadsheet IEEE float calculator for inputs of 4 bytes or 2 words. To download a copy, right click and select Save Target As... 

A four character ASCII string (4 typed letters) AE41 5652 = ® A V R More registers can be combined to form longer ASCII strings. Each register being used to store two ASCII characters (two bytes). 

What is byte and word ordering?

The Modbus specification doesn't define exactly how the data is stored in the registers. Therefore, some manufacturers implemented modbus in their equipment to store and transmit the higher byte first followed by the lower byte. (AE before 41). Alternatively, others store and transmit the lower byte first (41 before AE). Similarly, when registers are combined to represent 32-bit data types, Some devices store the higher 16 bits (high word) in the first register and the remaining low word in the second (AE41 before 5652) while others do the opposite (5652 before AE41) It doesn't matter which order the bytes or words are sent in, as long as the receiving device knows which way to expect it. For example, if the number 29,235,175,522 was to be sent as a 32 bit unsigned integer, it could be arranged any of these four ways.

AE41 5652 high byte first high word first

5652 AE41 high byte first low word first

41AE 5256 low byte first high word first

5256 41AE low byte first low word first 

What is a Modbus Map?

A modbus map is simply a list for an individual server device that defines - what the data is (eg. pressure or temperature readings)

- where the data is stored (which tables and data addresses)

- how the data is stored (data types, byte and word ordering)

Some devices are built with a fixed map that is defined by the manufacturer. While other devices allow the operator to configure or program a custom map to fit their needs. 

What is the difference between Modbus ASCII and Modbus RTU?

Modbus RTU and Modbus ASCII talk the same protocol. The only difference is that the bytes being transmitted over the wire are presented as binary with RTU and as readable ASCII with Modbus RTU. important to note about RTU is that the RTU message does not have a Start_of_text indication. The receiving party  in the communications uses a "silent" time in order to determine the start of a new message. ASCII does have a start-of-text token. Binary messages are shorter than ASCII and therefore theoretically faster to transmit/receive. You may be happy to see update rates of about 100 ms in your HMI/SCADA and could choose either communication.

- use RTU is possible
- use ASCII in case RTU is giving timeout problems on WinNT or when using slow communications media like 300 bps or dialup modems Most OPC Servers for Modbus support ASCII as well as RTU communications.. 

What are extended register addresses?

Since the range of the analog output holding registers is 40001 to 49999, it implies that there cannot be more than 9999 registers. Although this is usually enough for most applications, there are cases where more registers would be beneficial. Registers 40001 to 49999 correspond to data addresses 0000 to 270E. If we utilize the remaining data addresses 270F to FFFF, over six times as many registers can be available, 65536 in total. This would correspond to register numbers from 40001 to 105536. Many modbus software drivers (for Client PCs) were written with the 40001 to 49999 limits and cannot access extended registers in server devices. And many server devices do not support maps using the extended registers. But on the other hand, some server devices do support these registers and some Client software can access it, especially if custom software is written. 

How does 2-byte server addressing work?

Since a single byte is normally used to define the server address and each server on a network requires a unique address, the number of server on a network is limited to 256. The limit defined in the modbus specification is even lower at 247. To get beyond this limit, a modification can be made to the protocol to use two bytes for the address. The client and the servers would all be required to support this modification. Two byte addressing extends the limit on the number of servers in a network to 65535. By default, the Simply Modbus software uses 1 byte addressing. When an address greater than 255 is entered, the software automatically switches to 2 byte addressing and stays in this mode for all addresses until the 2 byte addressing is manually turned off. 

How can you send events and historical data?

Enron Modbus includes commands for moving events and historical data.. 

What is Enron Modbus?

For an ATS48, in SoMove the Fault history shows "Hour of Fault". How is this time determined?

In SoMove the Fault history shows "Hour of Fault". 

Product line:
ATS48, Altistart 48

all models


The time is based on the ATS48 operating time (run time), not a realtime clock.  Run time can be found in the Monitoring menu, parameter rnt. 

Since this follows Operating Time, if the Run time is reset using the rPr parameter under the drC menu, then the fault history Hour of Fault will match the updated run time.  Replacing the control board will also cause the Run time to reset to 0. 

Note:  To reach the maximum run time of 65535 hours, the unit would have to run for almost 7.5 years at continuous operation, 24hrs a day, 7 days a week.
