1.2: Connection

■Workstation PC

･A USB interface is used.

■USB-RS485 converter unit

･For the converter, System Sacom's "USB-RS485I RJ45-T4P" is recommended.

･By purchasing optional "external communication adapter USB-RS485I RJ45-T4P"

(product code 211880), the following connection can be made (workstation not

included).

2. COMMUNICATION INTERFACE

ԂCommunication protocol conforms to MODBUS and the protocol can be selected from RTU and

ASCII.

Refer to MODBUS standard specification and commercial reference manuals for details on

MODBUS.

2.1: Data transmission system

Transmission system: half-duplex asynchronous data transfer (polling/selecting)

Transmission distance: Max 500m (results may vary depending on environment)

Connection method: Multi-drop system (max 31 units)

Start bit: 1 bit

Transmission code: ASCII (ASCII mode)

Binary (RTU mode)

Error check: LRC (ASCII mode)

CRC-16 (RTU mode)

2.2: Frame configuration

In RTU mode, frame is composed of message portion only.

In ASCII mode, frame consists of start character ": (colon, 3AH)", message and end character

"CR (carriage return, ODH) + LF (line feed, 0AH)".

RTU mode: message

ASCII mode: : | message | CR | LF

2.3: Message configuration

MODBUS messages are composed of the following in both RTU andASCII modes.

Slave address

Function code

Data

Error check

2.4: Slave address

Slave address can be set from 1-99. Master normally communicates with one slave device. All

slave devices receive any message sent from the master in common, however, only the device

with slave address corresponding to the directive message responds.

2. COMMUNICATION INTERFACE

2.5: Function code

The function code communicates to the slave device what to execute. Function code data is

classified by type below.

Analog setting: each setting information type. Numerical value within 16 bits:

-32768 to 32767

Analog input data: measurement, status and other data. Numerical value within 16 bits.

Code

Function Unit MODBUS original function (reference)

Read analog settings

16 bit

Read content of maintenance register

Read analog input data

16 bit

Read content of input register

Write analog settings

16 bit

Write to single maintenance register

2.6: Data

Data configuration varies according to function code.

At the time of request from the master, data is composed of code number, data count, etc. of

target data to be read and written.

Response from the slave consists of data in relation to the request.

Basic MODBUS data is all integers of 16-bit, and the presence or absence of a sign is defined for

each data. Accordingly, by assigning a decimal to another address to convert into an integer or

fixing the decimal position, it is normalized and expressed on scale upper/lower limits.

2.7: Reference number

A reference number is assigned to data and it is necessary for reading and writing the data.

Reference number range is categorized as "analog input data" and "analog setting value"

according to data type.

Data type Reference number Relative number

Analog input data 30001-40000 Reference number -30001

Analog setting value 40001-50000 Reference number -40001

Relative number is the address number used during actual communication.
