DESCRIPTION

MODBUS ASCII/RTU is a master-slave communication protocol, able to support up to 247 slaves connected in a bus or a star network. The protocol uses a simplex connection on a single line. In this way, the communication messages move on a single line in two opposite directions.
MODBUS TCP is a variant of the MODBUS family. Specifically, it covers the use of MODBUS messaging in an “Intranet” or “Internet” environment using the TCP/IP protocol on a fixed port 502.
Master-slave messages can be:

• Reading (Function codes $01, $03, $04): the communication is between the master and a single slave. It allows to read information about the queried counter
• Writing (Function code $10): the communication is between the master and a single slave. It allows to change the counter settings
• Broadcast (not available for MODBUS TCP): the communication is between the master and all the connected slaves. It is always a write command (Function code $10) and requires logical number $00

In a multi-point type connection (MODBUS ASCII/RTU), a slave address (called also logical number) allows to identification of each counter during the communication. Each counter is preset with a default slave address (01) and the user can change it.
In case of MODBUS TCP, the slave address is replaced by a single byte, the Unit identifier.

LRC Generation

The Longitudinal Redundancy Check (LRC) field is one byte, containing an 8–bit binary value. The LRC value is calculated by the transmitting device, which appends the LRC to the message. The receiving device recalculates an LRC during receipt of the message and compares the calculated value to the actual value it received in the LRC field. If the two values are not equal, an error results. The LRC is calculated by adding together successive 8–bit bytes in the message, discarding any carries, and then two’s complementing the result. The LRC is an 8–bit field, therefore each new addition of a character that would result in a value higher than 255 decimal simply ‘rolls over’ the field’s value through zero. Because there is no ninth bit, the carry is discarded automatically.
A procedure for generating an LRC is:

1. Add all bytes in the message, excluding the starting ‘colon’ and ending CR LF. Add them into an 8–bit field, so that carries will be discarded.
2. Subtract the final field value from $FF, to produce the ones–complement.
3. Add 1 to produce the twos–complement.

Placing the LRC into the Message
When the 8–bit LRC (2 ASCII characters) is transmitted in the message, the high–order character will be transmitted first, followed by the low–order character. For example, if the LRC value is $52 (0101 0010):

Colon

‘:’

Count

| Data| Data| ….| Data| LRC

Hi ‘5’

Lo‘2’

| CR| LF

C-function to calculate LRC

CRC Generation
The Cyclical Redundancy Check (CRC) field is two bytes, containing a 16–bit value. The CRC value is calculated by the transmitting device, which appends the CRC to the message. The receiving device recalculates a CRC during receipt of the message and compares the calculated value to the actual value it received in the CRC field. If the two values are not equal, an error results.
The CRC is started by first preloading a 16–bit register to all 1’s. Then a process begins of applying successive 8–bit bytes of the message to the current contents of the register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and the parity bit, do not apply to the CRC.
During generation of the CRC, each 8–bit character is exclusive ORed with the register contents. Then the result is shifted in the direction of the least significant bit (LSB), with a zero filled into the most significant bit (MSB) position. The LSB is extracted and examined. If the LSB was a 1, the register is then exclusive ORed with a preset, fixed value. If the LSB was a 0, no exclusive OR takes place.
This process is repeated until eight shifts have been performed. After the last (eighth) shift, the next 8–bit character is exclusive ORed with the register’s current value, and the process repeats for eight more shifts as described above. The final contents of the register, after all the characters of the message have been applied, is the CRC value.
A calculated procedure for generating a CRC is:

1. Load a 16–bit register with $FFFF. Call this the CRC register.
2. Exclusive OR the first 8–bit byte of the message with the low–order byte of the 16–bit CRC register, putting the result in the CRC register.
3. Shift the CRC register one bit to the right (toward the LSB), zero–filling the MSB. Extract and examine the LSB.
4. (If the LSB was 0): Repeat Step 3 (another shift). (If the LSB was 1): Exclusive OR the CRC register with the polynomial value $A001 (1010 0000 0000 0001).
5. Repeat Steps 3 and 4 until 8 shifts have been performed. When this is done, a complete 8–bit byte will have been processed.
6. Repeat Steps 2 through 5 for the next 8–bit byte of the message. Continue doing this until all bytes have been processed.
7. The final content of the CRC register is the CRC value.
8. When the CRC is placed into the message, its upper and lower bytes must be swapped as described below.

Placing the CRC into the Message
When the 16–bit CRC (two 8–bit bytes) is transmitted in the message, the low- order byte will be transmitted first, followed by the high-order byte.
For example, if the CRC value is $35F7 (0011 0101 1111 0111):

CRC generation functions – With Table

All of the possible CRC values are preloaded into two arrays, which are simply indexed as the function increments through the message buffer. One array contains all of the 256 possible CRC values for the high byte of the 16–bit CRC field, and the other array contains all of the values for the low byte. Indexing the CRC in this way provides faster execution than would be achieved by calculating a new CRC value with each new character from the message buffer.

READING COMMAND STRUCTURE

• In the case of a module combined with a counter: The master communication device can send commands to the module to read its status and setup or to read the measured values, status and setup relevant to the counter.
• In the case of the counter with integrated communication: The master communication device can send commands to the counter to read its status, setup and measured values.
• More registers can be read, at the same time, sending a single command, only if the registers are consecutive (see Chapter 5). According to the MODBUS protocol mode, the read command is structured as follows.

Modbus ASCII/RTU
Values contained both in Query or Response messages are in hex format.
Query example in case of MODBUS RTU: 01030002000265CB

Response example in case of MODBUS RTU: 01030400035571F547

Modbus TCP
Values contained both in Query or Response messages are in hex format.

Response example in case of MODBUS TCP: 01000000000701040400035571

Floating Point as per IEEE Standard

• The basic format allows an IEEE standard floating-point number to be represented in a single 32-bit format, as shown below:

• where S is the sign bit, e’ is the first part of the exponent and f is the decimal fraction placed next to 1. Internally the exponent is 8 bits in length and the stored fraction is 23 bits long.

• A round-to-nearest method is applied to the calculated value of floating point.

• The floating-point format is shown as follows:

NOTE: Fractions (decimals) are always shown while the leading 1 (hidden bit) is not stored.

Example of conversion of value shown with floating point

WRITING COMMAND STRUCTURE

• In the case of a module combined with a counter: The master communication device can send commands to the module to program itself or to program the counter.
• In the case of a counter with integrated communication: The master communication device can send commands to the counter to program it.
• More settings can be carried out, at the same time, sending a single command, only if the relevant registers are consecutive (see chapter 5). According to the used MODBUS protocol type, the write command is structured as follows.

Modbus ASCII/RTU
Values contained both in Request or Response messages are in hex format.

EXCEPTION CODES

• In case of module combined with counter: When the module receives a not-valid query, an error message (exception code) is sent.
• In the case of the counter with integrated communication: When the counter receives a not-valid query, an error message (exception code) is sent.
• According to the MODBUS protocol mode, possible exception codes are as follows.

Modbus ASCII/RTU
Values contained in Response messages are in hex format.
Response example in case of MODBUS RTU: 01830131F0

Exception codes for MODBUS ASCII/RTU are following described:

• $01 ILLEGAL FUNCTION: the function code received in the query is not an allowable action.
• $02 ILLEGAL DATA ADDRESS: the data address received in the query is not allowable (i.e. the combination of register and transfer length is invalid).
• $03 ILLEGAL DATA VALUE: a value contained in the query data field is not an allowable value.
• $04 ILLEGAL RESPONSE LENGTH: the request would generate a response with a size bigger than that available for MODBUS protocol.

Modbus TCP
Values contained in Response messages are in hex format.
Response example in case of MODBUS TCP: 010000000003018302

Exception codes for MODBUS TCP are following described:

• $01 ILLEGAL FUNCTION: the function code is unknown by the server.
• $02 ILLEGAL DATA ADDRESS: the data address received in the query is not an allowable address for the counter (i.e. the combination of register and transfer length is invalid).
• $03 ILLEGAL DATA VALUE: a value contained in the query data field is not an allowable value for the counter.
• $04 SERVER FAILURE: the server failed during the execution.
• $05 ACKNOWLEDGE: the server accepted the server invocation but the service requires a relatively long time to execute. The server therefore returns only an acknowledgement of the service invocation receipt.
• $06 SERVER BUSY: the server was unable to accept the MB request PDU. The client application has the responsibility of deciding if and when to resend the request.
• $0A GATEWAY PATH UNAVAILABLE: the communication module (or the counter, in case of the counter with integrated communication) is not configured or cannot communicate.
• $0B GATEWAY TARGET DEVICE FAILED TO RESPOND: the counter is not available in the network.
