Preface DGC-2020HD Modbus™ Protocol

9469300991 Rev A iii

General Information

This document describes the Modbus communications protocol employed by DGC-2020HD systems and how to exchange information with DGC-2020HD systems over a Modbus network. DGC-2020HD systems communicate by emulating a subset of the Modicon 984 Programmable Controller.

Modbus communications use a master-slave technique in which only the master can initiate a transaction. This transaction is called a query. When appropriate, a slave (DGC-2020HD) responds to the query. When a Modbus master communicates with a slave, information is provided or requested by the master. Information residing in the DGC-2020HD is grouped categorically as follows:

• General

• Global Settings

• Configuration

• Binary Points

• Metering

• Breaker Settings

• Bias Control

• Pulse Outputs

• Bus Condition

• DGC Settings

• Control Settings

• Protection Settings

• Remote Module Settings

All supported data can be read as specified in the Register Table. Abbreviations are used in the Register Table to indicate the register type. Register types are:

• Read/Write = RW

• Read Only = R

When a slave receives a query, the slave responds by either supplying the requested data to the master or performing the requested action. A slave device never initiates communications on the Modbus and will always generate a response to the query unless certain error conditions occur. The DGC-2020HD is designed to communicate on the Modbus network only as a slave device.

Refer to the Instruction Manual for Digital Genset Controller DGC-2020HD (Basler Publication

9469300990) for Modbus communication setup and wiring.

Message Structure

Device Address Field

The device address field contains the unique Modbus address of the slave being queried. The addressed slave repeats the address in the device address field of the response message. This field is 1 byte.

Although Modbus protocol limits a device address from 1 - 247. The address is user-selectable at installation and can be altered during real-time operation.

Function Code Field

The function code field in the query message defines the action to be taken by the addressed slave. This field is echoed in the response message and is altered by setting the most significant bit (MSB) of the field to 1 if the response is an error response. This field is 1 byte in length.

The DGC-2020HD maps all available data into the Modicon 984 holding register address space supports the following function codes:

• Function 03 (03 hex) - read holding registers

• Function 06 (06 hex) - preset single register

• Function 08 (08 hex), subfunction 00 - diagnostics: return query data

• Function 08 (08 hex), subfunction 01 - diagnostics: restart communications option

• Function 08 (08 hex), subfunction 04 - diagnostics: force listen only mode

• Function 16 (10 hex) - preset multiple registers

Data Block Field

The query data block contains additional information needed by the slave to perform the requested function. The response data block contains data collected by the slave for the queried function. An error response will substitute an exception response code for the data block. The length of this field varies with each query.

Error Check Field

The error check field provides a method for the slave to validate the integrity of the query message contents and allows the master to confirm the validity of response message contents. This field is 2 bytes.

Modbus Modes of Operation

A standard Modbus network offers the remote terminal unit (RTU) transmission mode and Modbus/TCP mode for communication. DGC-2020HD systems support the Modbus/TCP mode and RS-485 mode at the same time. To enable editing over Modbus TCP, or RS-485, the unsecured access level for the port must be configured to the appropriate access level. See the Instruction Manual for Digital Genset Controller DGC-2020HD (Basler Publication 9469300990) for more information on security and access levels. These two modes of operation are described below.

A master can query slaves individually or universally. A universal ("broadcast") query, when allowed, evokes no response from any slave device. If a query to an individual slave device requests actions unable to be performed by the slave, the slave response message contains an exception response code defining the error detected. Exception response codes are quite often enhanced by the information found in the "Error Details" block of holding registers.

The Modbus protocol defines a simple Protocol Data Unit (PDU) independent of the underlying communication layers. The mapping of the Modbus protocol on specific buses or networks can introduce some additional fields on the Application Data Unit (ADU). See Figure 1.

ADU

Modbus Over Serial Line

Message Structure

Master initiated queries and DGC-2020HD responses share the same message structure. Each message is comprised of four message fields. They are:

• Device Address (1 byte)

• Function Code (1 byte)

• Data Block (n bytes)

• Error Check field (2 bytes)

Each 8-bit byte in a message contains two 4-bit hexadecimal characters. The message is transmitted in a continuous stream with the LSB of each byte of data transmitted first. Transmission of each 8-bit data byte occurs with one start bit and either one or two stop bits. Parity checking is performed, when enabled,

and can be either odd or even. The transmission baud rate is user-selectable, and can be set at installation and altered during real-time operation. DGC-2020HD Modbus supports baud rates up to

115200. The factory default baud rate is 19200.

DGC-2020HD systems support RS-485 compatible serial interfaces. This interface is accessible from the left side panel of the DGC-2020HD.

Message Framing and Timing Considerations

When receiving a message via the RS-485 communication port, the DGC-2020HD requires an inter-byte latency of 3.5 character times before considering the message complete.

Once a valid query is received, the DGC-2020HD waits a specified amount of time before responding. This time delay is set on the Modbus Setup screen under Communications in BESTCOMSPlus

parameter contains a value from 10 - 10,000 milliseconds. The default value is 10 milliseconds.

Modbus on TCP/IP

Application Data Unit

The following describes the encapsulation of a Modbus request or response when it is carried on a Modbus TCP/IP network. See Figure 2.

Modbus TCP/IP ADU

Figure 2. Modbus Request/Response Over TCP/IP

A dedicated header is used on TCP/IP to identify the Modbus Application Data Unit. It is called the MBAP header (Modbus Application Protocol header).

This header provides some differences compared to the Modbus RTU application data unit used on a serial line:

• The Modbus ‘slave address’ field usually used on Modbus Serial Line is replaced by a single byte

‘Unit Identifier’ within the MBAP header. The ‘Unit Identifier’ is used to communicate via devices such as bridges, routers, and gateways that use a single IP address to support multiple independent Modbus end units.

• All Modbus requests and responses are designed in such a way that the recipient can verify that

a message is finished. For function codes where the Modbus PDU has a fixed length, the function code alone is sufficient. For function codes carrying a variable amount of data in the request or response, the data field includes a byte count.

• When Modbus is carried over TCP, additional length information is carried in the MBAP header to

allow the recipient to recognize message boundaries even if the message has been split into multiple packets for transmission. The existence of explicit and implicit length rules and use of a

Modbus or a Modbus serial line slave through a gateway between an Ethernet TCP/IP network and a Modbus serial line. This field is set by the Modbus Client in the request and must be returned with the same value in the response by the server.

Note: All Modbus/TCP ADU are sent via TCP on registered port 502.

Error Handling and Exception Responses

Any query received that contains a non-existent device address, a framing error, or CRC error is ignored. No response is transmitted. Queries addressed to the DGC-2020HD with an unsupported function or illegal values in the data block result in an error response message with an exception response code. The exception response codes supported by the DGC-2020HD are provided in Table 3.

DGC-2020HD Modbus via Ethernet

Modbus can communicate through Ethernet if the IP address of the DGC-2020HD is configured as described in the Instruction Manual for Digital Genset Controller DGC-2020HD (Basler Publication

9469300990).

Detailed Message Query and Response for RTU Transmission Mode

A detailed description of DGC-2020HD supported message queries and responses is provided in the following paragraphs.

Read Holding Registers

Query

This query message requests a register or block of registers to be read. The data block contains the starting register address and the quantity of registers to be read. A register address of N will read holding register N+1. If the query is a broadcast (device address = 0), no response message is returned.

Device Address Function Code = 03 (hex)

Starting Address Hi Starting Address Lo No. of Registers Hi No. of Registers Lo CRC Hi error check CRC Lo error check

The number of registers cannot exceed 125 without causing an error response with the exception code for an illegal function.

Response

The response message contains the data queried. The data block contains the block length in bytes followed by the data (one Data Hi byte and one Data Lo byte) for each requested register.

Reading an unassigned holding register returns a value of zero.

Device Address Function Code = 03 (hex)

Byte Count Data Hi (For each requested register, there is one Data Hi and one Data Lo.) Data Lo . . Data Hi Data Lo CRC Hi error check CRC Lo error check

Return Query Data

This query contains data to be returned (looped back) in the response. The response and query messages should be identical. If the query is a broadcast (device address = 0), no response message is returned.

Device Address Function Code = 08 (hex) Subfunction Hi = 00 (hex) Subfunction Lo = 00 (hex) Data Hi = xx (don't care) Data Lo = xx (don't care)

DGC-2020HD Modbus™ Protocol General Information

6 9469300991 Rev A

CRC Hi error check CRC Lo error check

Restart Communications Option

This query causes the remote communications function of the DGC-2020HD to restart, terminating an active listen only mode of operation. No effect is made upon primary relay operations. Only the remote communications function is affected. If the query is a broadcast (device address = 0), no response message is returned.

If the DGC-2020HD receives this query while in the listen only mode, no response message is generated. Otherwise, a response message identical to the query message is transmitted prior to the communications restart.

Device Address Function Code = 08 (hex)

Subfunction Hi = 00 (hex) Subfunction Lo = 01 (hex) Data Hi = xx (don't care) Data Lo = xx (don't care) CRC Hi error check CRC Lo error check

Listen Only Mode

This query forces the addressed DGC-2020HD to the listen only mode for Modbus communications, isolating it from other devices on the network. No responses are returned.

While in the listen only mode, the DGC-2020HD continues to monitor all queries. The DGC-2020HD does not respond to any other query until the listen only mode is removed. All write requests with a query to Preset Multiple Registers (Function Code = 16) are also ignored. When the DGC-2020HD receives the restart communications query, the listen only mode is removed.

Device Address Function Code = 08 (hex)

Subfunction Hi = 00 (hex) Subfunction Lo = 04 (hex) Data Hi = xx (don't care) Data Lo = xx (don't care) CRC Hi error check CRC Lo error check

Preset Multiple Registers

A preset multiple registers query could address multiple registers in one slave or multiple slaves. If the query is a broadcast (device address = 0), no response message is returned.

Query

A Preset Multiple Register query message requests a register or block of registers to be written. The data block contains the starting address and the quantity of registers to be written, followed by the Data Block byte count and data. The DGC-2020HD will perform the write when the device address in query is a broadcast address or the same as the DGC-2020HD Modbus Unit ID (device address).

A register address of N will write Holding Register N+1.

Data will cease to be written if any of the following exceptions occur.

• Queries to write to Read Only registers result in an error response with Exception Code of “Illegal

Data Address”.

• Queries attempting to write more than 100 registers cause an error response with Exception

Code “Illegal Function”.

General Information DGC-2020HD Modbus™ Protocol

9469300991 Rev A 7

• An incorrect Byte Count will result in an error response with Exception Code of “Illegal Data

Value”.

• There are several instances of registers that are grouped together to collectively represent a

single numerical DGC-2020HD data value (i.e. - floating point data, 32-bit integer data, and strings). A query to write a subset of such a register group will result in an error response with Exception Code “Illegal Data Address”.

• A query to write a not allowed value (out of range) to a register results in an error response with

Exception Code of “Illegal Data Value”.

Device Address Function Code = 10 (hex)

Starting Address Hi Starting Address Lo No. of Registers Hi No. of Registers Lo Byte Count Data Hi Data Lo . . Data Hi Data Lo CRC Hi error check CRC Lo error check

Response

The response message echoes the starting address and the number of registers. There is no response message when the query is a broadcast (device address = 0).

Device Address Function Code = 10 (hex)

Starting Address Hi Starting Address Lo No. of Registers Hi No. of Registers Lo CRC Hi Error Check CRC Lo Error Check

Preset Single Register

A Preset Single Register query message requests a single register to be written. If the query is a broadcast (device address = 0), no response message is returned.

Note: Only data types INT16, INT8, UINT16, UINT8, and String (not longer than 2 bytes), can be preset by this function.

Query

Data will cease to be written if any of the following exceptions occur.

• Queries to write to Read Only registers result in an error response with Exception Code of “Illegal

Data Address”.

• A query to write an unallowed value (out of range) to a register results in an error response with

Exception Code of “Illegal Data Value”.

Data Formats

DGC-2020HD systems support the following data types:

• Data types mapped to 2 registers

o Signed Integer 32 (Int32) o Unsigned Integer 32 (Uint32) o Floating Point (Float) o IP Address (IP Address) o Strings maximum 4 characters long (String)

• Data types mapped to 1 register

o Unsigned Integer 16 (Uint16) o Unsigned Integer 8 (Uint8) o Strings maximum 2 characters long (String)

• Data types mapped to more than 2 registers

o Strings longer than 4 characters (String)

Floating Point Data Format (Float)

The Modbus floating point data format uses two consecutive holding registers to represent a data value. The first register contains the low-order 16 bits of the following 32-bit format:

• MSB is the sign bit for the floating-point value (0 = positive).

• The next 8 bits are the exponent biased by 127 decimal.

• The 23 LSBs comprise the normalized mantissa. The most-significant bit of the mantissa is

always assumed to be 1 and is not explicitly stored, yielding an effective precision of 24 bits.

The value of the floating-point number is obtained by multiplying the binary mantissa times two raised to the power of the unbiased exponent. The assumed bit of the binary mantissa has the value of 1.0, with the remaining 23 bits providing a fractional value. Table 4 shows the floating-point format.

Table 4. Floating Point Format

Sign Exponent + 127 Mantissa

1 Bit 8 Bits 23 Bits

The floating-point format allows for values ranging from approximately 8.43X10^ floating-point value of all zeroes is the value zero. A floating-point value of all ones (not a number) signifies a value currently not applicable or disabled.

Example will read from two consecutive holding registers as follows:

Holding Register Value K (Hi Byte) hex 1C K (Lo Byte) hex 00 K+1 (Hi Byte) hex 47 K+1 (Lo Byte) hex BB

: The value 95,800 represented in floating-point format is hexadecimal 47BB1C00. This number

9469300991 Rev A 9

Long Integer Data Format (Uint32, Int32, and IP Address)

The Modbus long integer data format uses two consecutive holding registers to represent a 32-bit data value. The first register contains the low-order 16 bits and the second register contains the high-order 16 bits.

Example will read from two consecutive holding registers as follows:

Holding Register Value K (Hi Byte) hex 76 K (Lo Byte) hex 38 K+1 (Hi Byte) hex 00 K+1 (Lo Byte) hex 01

The same byte alignments are required to write.

: The value 95,800 represented in long integer format is hexadecimal 0x00017638. This number

Integer Data Format (Uint16) or Bit-Mapped Variables in Uint16 Format

The Modbus integer data format uses a single holding register to represent a 16-bit data value.

Example a holding register as follows:

Holding Register Value K (Hi Byte) hex 12 K (Lo Byte) hex 34

The same byte alignments are required to write.

The Uint16 Data Format is listed in Binary Points below.

Example: specific bit-mapped data such as 1100-0 indicates bit 0 of register 1100 is mapped to RF-TRIG.

: The value 4660 represented in integer format is hexadecimal 0x1234. This number will read from

Register 1100 occupies 16 rows in the Register Table where each row gives the name of

Short Integer Data Format/Byte Character Data Format (Uint8)

The Modbus short integer data format uses a single holding register to represent an 8-bit data value. The holding register high byte will always be zero.

Example from a holding register as follows:

Holding Register Value K (Hi Byte) hex 00 K (Lo Byte) hex 84

The same byte alignments are required to write.

: The value 132 represented in short integer format is hexadecimal 0x84. This number will read

String Data Format (String)

The Modbus string data format uses one or more holding registers to represent a sequence, or string, of character values. If the string contains a single character, the holding register high byte will contain the ASCII character code and the low byte will be zero.

Example

Holding Register Value K (Hi Byte) ‘P’ K (Lo Byte) ‘A’ K+1 (Hi Byte) ‘S’ K+1 (Lo Byte) ‘S’ K+2 (Hi Byte) ‘W’ K+2 (Lo Byte) ‘O’

: The string “PASSWORD” represented in string format will read as follows:

DGC-2020HD Modbus™ Protocol General Information

10 9469300991 Rev A

K+3 (Hi Byte) ‘R’ K+3 (Lo Byte) ‘D’

Example

Holding Register Value K (Hi Byte) ‘P’ K (Lo Byte) hex 00 K+1 (Hi Byte) hex 00 K+1 (Lo Byte) hex 00 K+2 (Hi Byte) hex 00 K+2 (Lo Byte) hex 00 K+3 (Hi Byte) hex 00 K+3 (Lo Byte) hex 00

The same byte alignments are required to write.

: If the above string is changed to “P”, the new string will read as follows:

CRC Error Check

This field contains a two-byte CRC value for transmission error detection. The master first calculates the CRC and appends it to the query message. The DGC-2020HD system recalculates the CRC value for the received query and performs a comparison to the query CRC value to determine if a transmission error has occurred. If so, no response message is generated. If no transmission error has occurred, the slave calculates a new CRC value for the response message and appends it to the message for transmission.

The CRC calculation is performed using all bytes of the device address, function code, and data block fields. A 16-bit CRC-register is initialized to all 1's. Then each eight-bit byte of the message is used in the following algorithm:

First, exclusive-OR the message byte with the low-order byte of the CRC-register. The result, stored in the CRC-register, will then be right-shifted eight times. The CRC-register MSB is zero-filled with each shift. After each shift, the CRC-register LSB is examined. If the LSB IS a 1, the CRC-register is then exclusive-ORed with the fixed polynomial value A001 (hex) prior to the next shift. Once all bytes of the message have undergone the above algorithm, the CRC-register will contain the message CRC value to be placed in the error check field.
