1. Overview of the Communications Function

The DTSX200 supports communications based on the Modbus protocol via built-in Ethernet and RS-232C ports as communications interfaces. Using Modbus communications, a client/master can configure, control, as well as retrieve status information and measurement data from a remote DTSX200. The figure below shows an example system configuration.

Control device

RS-232C

PC

If connection to the DTSX200 is by Ethernet, the Modbus/TCP communications protocol is used, the DTSX200 runs as a Modbus/TCP server and can connect to a maximum of four client devices. If connection to the DTSX200 is by RS-232C, the DTSX200 runs as a slave device and communicates one-to-one with a master device. Both the RTU and ASCII serial transmission modes are supported. For RS-232C communications, a slave address must be defined for the DTSX200.

< 4. Modbus Communications Protocol> 11

IM 39J06B45-02E

4. Modbus Communications Protocol 4.1. Overview

In a communications system based on the Modbus protocol, the master initiates a transaction and the slave responds to it. The communications protocol is as follows: 1) A master sends a request message to slaves. 2) Each slave compares the device number in the received message to its own device

number. 3) If the device numbers match, the slave sends a response message. 4) If the device numbers do not match, the slave discards the received request

message and waits for the next request message. By specifying a device number in a request message, a master can communicate with a specific slave even when multiple slaves are connected to the same line.

4.2. Message Structure Each request message or response message comprises four fields, namely a device number, a function code, a data field and an error check code, which are transmitted sequentially in the given order. Modbus defines two serial transmission modes, namely, the RTU mode and the ASCII mode, with different message formats. The ASCII mode permits only data comprising ASCII characters 0-9 and A-F.

Device number (1 byte)Function code (1 byte)

Data (n bytes)Error check code (CRC) (2 bytes)

RTU mode

Start (1 character): colon (:)Device number (2 characters)Function code (2 characters)

Data (n characters)Error check code (LRC) (2 characters)

End (2 characters): CR+LF

ASCII mode Each message field is described in more details below.

4.2.1. Device Number The device number specifies a slave. Only the DTSX200 with a matching device number will process the request message.

4.2.2. Function Code The function code specifies the function to be executed by the slave.

SEE ALSO For more details on the function code, see Section 4.4, “Function Codes.”

4.2.3. Data The data field contains data required for executing the function defined by the function code. The data structure varies with the function code. Each DTSX200 setting is assigned a unique register number. To read or write a setting, specify its register number. Register numbers must be specified as relative addresses in transmitted messages.


IM 39J06B45-02E

The relative address of a register is given by the formula: Relative address = Last 5 digits of the register number − 1

For example, to specify register number 400003 as a parameter for a function code, you should specify relative address 00002 in the message:

Relative address = (last 5 digits of 400003) − 1 = 0002

4.2.4. Error Check Code The error check code is used for detecting message errors (bit changes), if any, introduced during signal transmission. CRC (Cyclic Redundancy Check) is used in RTU serial transmission mode. LRC (Longitudinal Redundancy Check) is used in ASCII serial transmission mode.

4.3. Slave Response

4.3.1. Normal Response If no error occurs in relation to the function requested in a properly received request message, the slave creates and returns a normal response message. The message structure is as described in Section 4.2. The content of the data field varies with the function code.

SEE ALSO For details on the function code, see Section 4.4, “Function Codes.”

4.3.2. Exception Response If a request message contains a non-transmission-related error (such as a non-existent function code), the slave creates and returns an error response message without executing the request. The figure below shows the structure of an error response message. In an error response, the function code is 80H higher than the function code of the original request.

Device numberFunction code+80H

Error codeError check code (CRC)

RTU mode

Start (1 character): colon (:)Device number

Function code+80H

Error codeError check code (LRC)

End (2 characters): CR+LF

ASCII mode The error codes are listed in the table below.

Table: Error Codes Error Code Error Description

01H Invalid function code The specified function code is non-existent. Check the specified function code.

02H Invalid address for coil or register The specified relative address of a register number is not allowed for the specified function code.

03H Invalid number of registers The specified number of registers is too large and covers a range containing non-existent register numbers.


IM 39J06B45-02E

4.3.3. No Response A slave ignores a request message and returns no response if: - The device number specified in the request message does not match slave’s own

device number; - The error check code does not match; or - A transmission error (such as a parity error) is detected.

4.4. Function Codes In the Modbus protocol, each function code can only act on certain allocated register numbers. The table below shows the mapping between function codes and register numbers for the DTSX200.

Table: Mapping between Function Codes and Addresses Function Code Register Number

Number Function Object Number Description 03H Read (contiguous) Holding registers 4XXXXX Read-write word data 04H Read (contiguous) Input registers 3XXXXX Read-only word data 06H Write Holding register 4XXXXX Read-write word data 10H Write (contiguous) Holding registers 4XXXXX Read-write word data

6. Address Map 6.1. Handling of Fractional Data

Some DTSX200 settings allow fractional values but transmission of fractional values in messages is not allowed. In the address map tables in the following pages, a setting parameter allowing fractional values is specified with its fixed number of decimal places. When handling fractional data, calculate its proper value using its fixed number of decimal places as shown in the following examples. Example 1: Reading the fiber length setting for zone 1 of channel 1 (register number: 402051) If the DTSX200 returns a value of 1000 for this parameter, which has 1 decimal place, the fiber length of zone 1 of channel 1 is given by: 1000÷10 = 100.0 Example 2: Writing the fiber length setting for zone 1 of channel (register number: 402051) To set the fiber length of zone 1 of channel 1 to 100.0, the value to be written to the DTSX200 for this parameter, which has 1 decimal place, is given by: 100.0x10 = 1000

TIP - These parameters cannot be modified during LAS conversion.

- Be sure to specify a channel number using register number 433025 and a parameter type using register number 433026 before reading or writing its parameter value using register number 433027.

- Only non-control ASCII characters and the null byte (0x00) are allowed. Two-byte coded data is not supported.

- When writing a character string parameter, always append a null byte (0x00) at the end of the character string data. Otherwise, the parameter may be improperly set (partially modified or unmodified).

- To specify a double-quote (“) character within character string data, precede it with a backslash (\) escape character. In this case, two bytes are used for the character but the number of allowable characters for the parameter value is not reduced by one.

- The screen capture below maps the LAS conversion header fields displayed in the DTSX200 Control Visualization Software LAS2.0 Data Conversion to their allocated parameters. Each label shown in the screen capture maps to a value for the parameter (register 433026) in the above table.

- Be sure to specify a parameter ID using register number 435330 before reading or writing its parameter value using register number 435331.

- Reading of the destination server user ID (parameter 2), password (parameter 3) and form data name (parameter 5) is prohibited for security reason.

- Only non-control ASCII characters and the null byte (0x00) are allowed. Two-byte coded data is not supported.

- When writing a character string parameter, always append a null byte (0x00) at the end of the character string data. Otherwise, the parameter may be improperly set (partially modified or unmodified).

- To specify a double-quote (“) character within character string data, precede it with a backslash (\) escape character. In this case, two bytes are used for the character but the number of allowable characters for the parameter value is not reduced by one.


IM 39J06B45-02E

- For the URI parameter, characters other than reserved characters and unreserved characters defined in RFC2396 and the ‘#’ character must be encoded as URI escape characters. The table below lists the characters that must be escaped with their escape characters.

Characters Escape characters (URI encoding)

space %20 " %22 % %25 < %3C > %3E [ %5B \ %5C ] %5D ^ %5E ` %60 { %7B | %7C } %7D

The pound (#) character is used as a delimiter character for URI references and fragment identifiers. Only one ‘#’ character can be specified in a URI. For details on fragment identifier, see the RFC2396.

- The screen capture below maps the LAS conversion transmission settings displayed in the DTSX200 Control Visualization Software LAS2.0 Data Conversion to their associated parameters. Each label shown in the screen captures maps to a value for the parameter ID(register 435330) in the above table. Example: The field labeled as (13)-0 in the screen capture refers to the URI parameter.

TIP - These are read-only registers, which can be read but not written.

- Registers for the latest measurement data are updated with the measurement result at the end of each measurement so that the latest measurement data is constantly available.

- Measurement data registers for each channel are updated at the end of each measurement for the corresponding channel.

- The figure below shows the data structure of measurement data.

Each tag data group stores tag data for 100 zones of a channel. The tag data content depends on the following parameters:- zone start depth- tag zone depth- data type (maximum, minimum, average, difference or slope)A tag data group for a channel is updated at the end of each measurement for the corresponding channel.
