COMMUNICATION FUNCTIONS

• On a system operating on the RS-232C interface, a master station (a host computer, usually a PC) is connected to the instrument in a point-to-point configuration. At this time, only one instrument can communicate with the master station using a preset station address.

• On a system operating on the RS-485 interface, up to 31 instruments (see * 1) can be connected to a master station. Station addresses are then used to identify other stations for communication.

• The communication protocol and format conform to the RS-232C and RS-485 interfaces.

•

When the following procedure is established during communication, instrument data can be read or written:

1. The master station (host computer) transmits a request message to the slave station.

2. The master station receives a response message from the slave station.

•

The master station issues two types of requests to a slave station: read and write.

•

The type of read/write data can be optionally selected with a data address.

• CPL (Controller Peripheral Link) Communications isYamatake host communication protocol.

An SRF206/212/224 supporting an RS-232C communication function is wired for communication as shown below.

•

Communication with the master station in a point-to-point configuration

The SRF206/212/224 is provided with three communication terminals (RD,

SD and SG). Data may not be output unless the other terminals of the master station RS-232C interface are short-circuited as shown in figure on the next page.

Usually, the pin array of the RS-232C connector of a PC is as shown in the figure on the next page (terminal mode). The locations of pins SD and RD, RS and CS and DR and ER may be reversed (MODEM mode), but this is rare.

Check the RS-232C pin array in the host computer instruction manual.

COMMUNICATION PROCEDURE

4 - 1 Outline of Communication Procedure and Messages

This chapter outlines communication procedures and the concept behind message configuration.

■

Communication Procedure

The following is a simple breakdown of the communication procedure:

1. The master station transmits an instruction message to a slave station to specify a station for communication.

2. The slave station processes the instruction message, and executes read and write operations.

3. The slave station transmits a response message according to the contents of processing.

4. The master station receives the response message and executes processing.

■

Message Configuration

A message consists of two layers as shown below. Both the instruction message from a master station and the response message from a slave station take this form.

●

Data link layer

•

This layer contains the basic information required for communication.

•

It also contains message destination and check information.

● Application layer

• This layer is where data read and write operations are executed.

• The content of this layer varies according to the purpose of the operation.

The figure below shows the individual layers.

Application layer

Data link layer

A total of 31 stations

Instruction message from master station

Response message from slave station

Slave stations

Master station

The driver of the data link layer knows:

¥ Destination (station address)

¥ Load check sheet (checksum)

Application layer

Data link layer

The load (data) of the application layer changes every time according to the purpose of the operation.

■ Examples

Messages have the following structure:

● Read instruction

・Instruction message

Data link layer Application layer Data link layer

・Response message

STX 0 1 0 0 X 0 0 , 0 , 4 2 ETX 9 4 CR LF


● Write instruction

The following sections describe in detail the data link layer and application layer:

■ Data Address Concept

The SRF206/212/224 uses “data addresses” to read and write data. Data addresses allow data to be written and read to and from a corresponding address for the data.

Data A

Data B

See Chapter 5. “COMMUNICATION DATA TABLE” for information on the relationship between data and address.

4-2


4 - 2 Data Link Layer

■

Description

• The data link layer contains eight types of basic message transmission information.

• The instruction message and response message have the same structure in the data link layer.

STX

Station address

Subaddress

Device ID code

The underlined SRF200 parameters ( ) are set to fixed values.

ETX

Checksum

CR

LF

02H 30H 41H 30H 30H 58H 52H 53H 2CH 31H 30H 30H 31H 57H 2CH 32H 03H 38H 41H 0DH 0AH

STX 0 A 0 0 X R S , 1 0 0 1 W , 2 ETX 8 A CR LF


The following describes each function of the data link layer:

●

STX (Start of TeXt)

◆ Role

: Indicates the beginning of a message.

Description • Fixed at 02H.

• When the instrument receives an STX, it is identified as the first character of a new instruction message regardless of location with a message.

●

Station address

◆ Role

: Specifies the destination station, and allows communication with the specified station.

Description • If “0” is set as the station address, the communication function is stopped.

So, to enable communication be sure to set an address value of

“1” or more.

• Two hexadecimal characters. For details, see the example.

• See

Chapter 3. “SETTINGS”

for information on station address settings.

Example : When the station address of the other instrument is “10”:

1. 10 (decimal) = 0AH (hexadecimal)

2. This can be converted into character codes:

0 = 30H, A = 41H

3. “0A” (30H, 41H) calculated in example 2 is used as the station address.


Note that the function of the station address differs entirely from that of the data address of the application layer.

●

Subaddress

Description

:

The subaddress is meaningless on the SRF206/212/224 .

Be sure to set a subaddress of “00” (30H, 30H) that has the same format as the station address.

●

Device ID code

Description

:

Only character codes “X” (58H) or “x” (78H) can be set on the

SRF206/212/224 .

4-3


●

ETX (End of TeXt)

◆ Role

: Indicates the end of the application layer.

Description : Fixed at 03H.

●

Checksum

◆ Role

: A value to be used to check whether or not a message has been corrupted by an error (such as noise) during communication.

Description

•

Two hexadecimal characters.

•

This function operates as follows:

1. Add one byte each to the character codes of the message from

STX to ETX.

2. Derive the two’s complement of the result of this addition.

3. Convert the result into character codes.

Example : The instruction message on the preceding page is used in the following example:

1. Add one byte each to the character codes from STX to ETX.

The lower-order one byte of the calculation result is 76H.

2. The result of two’s complement addition is 8AH.

3. 85H is converted into character codes and used as the checksum value. The result is “8A”, (38H) and (41H).

See the station address example (on the preceding page) for information on character code conversion.


The checksum in the instruction message can be omitted, but no checksum is then included in the response message. The checksum function should not be omitted to ensure proper message reception and transmission.

4-4


●

CR and LF (Carriage Return/Line Feed)

◆ Role

: Indicates the end of a message.

Description • “CR” is (0DH), and “LF” is (0AH).

• Be sure to use CR and LF in pair.


● If any of the following errors occur in the data link layer, the instrument respond:

• The communication conditions for both stations do not match (different transmission speeds or the occurrence of a parity error).

• The address of the transmitting station differs from the station address for the receiving station.

• The station address is “00”.

• STX, ETX, CR and LF are not placed at the specified positions.

• The device ID code is neither “X” nor “x”.

• The station address, subaddress or checksum is not two charactersdoes not long.

• The calculation result of the checksum does not match the checksum of the message.

• Non-specified characters are included in the message.

● The data link layer contains a response message which is identical to the instruction message except for the checksum function.

● Use upper-case characters “A” to “F” in the hexadecimal numerics for the station address and checksum.

4 - 7 Timing Specifications

■ Timing Specifications for Instruction and Response Messages

When a slave station is connected with the master station directly via the RS-232C interface, the following precautions regarding the transmission timing of instruction messages from the master station and response messages from the slave station should be observed:

● Response time-out

The maximum response time from the end of the instruction message transmission by the master station until when the master station receives a response message from the slave station is one second ((1) in figure). So, the response time-out should be set to one second.

Generally, when a response time-out occurs, the instruction message is resent.

For details, see Chapter 6. “COMMUNICATION PROGRAM FOR MASTER

STATION.”

● Transmission start time

A wait time of 10ms or more is required before the master station starts to transmit the next instruction message (to the same slave station or a different slave station) after the end of receiving a response message ((2) in figure).

COMMUNICATION DATA TABLE

5 - 1 Basic Communication Data Processing

■

Communication Data Types and Formats

●

Types of communication data

There are two types of communication data:

●

Run status: Data indicating the run status (PV, event, etc.) of the instrument.

●

Configuration: Data (event setting values, etc.) for setting the instrument status.

●

Format of communication data

Communication data is classified into the following formats:

●

Numeric data: Data indicating a numeric value (PV, etc.).

●

Bit data: Data where each bit is significant (alarms, etc.). Bit data must

●

Text data: be composed by transmission and decomposed by reception.

Data indicating text.

Text data (unit, tag name, etc.) must be converted according to the character code table.

For details on character data, see ■

SRF Character Code

Table (App.-2)

.

IMPORTANT

Writing to EEPROM addresses is guaranteed only up to 100,000 times.

■

Communication Data Storage Memory

●

Memory type

The communication data handled on the

SRF206/212/224

(excluding some data items such as time data) is stored in the following two types of memory:

•

• RAM:

EEPROM:

Stored data is cleared when the power is turned OFF. However data can be written to this memory any number of times.

Stored data is retained even when the power is turned OFF, whereas data write operations are limited to a total of 100,000 times owing to device characteristics.

When data is written to RAM by communications on the

SRF206/212/224

, the data is also automatically written to EEPROM excluding control data and other data items.

●

Communication memory devices

Data is transferred automatically between RAM and EEPROM as required. For this reason, there is no need to be conscious of these two types of memory.

5-1


■ Data Address

The data addresses are allocated as in the table below.

Communication Data

Control data

Process data

Event data

Digital I/O

Common data

Segment table data

Channel data

Communication data

Address

300 to 399

400 to 449

500 to 599

600 to 999

1000 to 1099 nn00 to nn99 *

3500 to 3999

* Address “nn” is a value obtained by adding “10” to channels “1” to “24”.

For example, “nn” becomes “11” in the case of channel 1.

■ Data Read/Write Count

The number of data items that can be read and written continuously in a single communication operation is determined within a range in which the command frame length is less than 256bytes.

Data in the continuous data that does not exist due to differences in model Nos. is handled as follows:

• Reading: “0” is read as dummy data (warning response is returned).

• Writing: Data is not written (warning response is returned).


Command frames up to 256bytes in length sometimes cannot be handled depending on the hardware and software of the master station in use. (For example, N88 BASIC can handle only up to 255bytes.) If this happens, limit the command frame length to match the limitations of the master station.

■ Data Unit and Decimal Point Position

Read/write data is not appended with a decimal point.

The unit and decimal point position is determined for each data item.

For details on the data unit and decimal point position, see the SRF206/212/224

Installation/Operation Manual.

Example:

Let’s assume that the data to be read and written is numeric data “105”. The data unit and decimal point position is automatically determined by the data address and instrument setup items.

So, the numeric data “105” can have various meaning such as 10.5% and 105°C depending on the data address to be read and written.

«

«

«

«

Sets and reads the copy source channel in channel data copying.

1 to number of channels

Sets and reads the copy destination channel lower limit in channel data copying.

1 to (902W) value

• When 901W and 902W are written simultaneously by a single write command, the 902W data to be written simultaneously is written normally, if it is greater than the 901W data to be written, even if the 901W data to be written is greater than the 902W data before it is written.

For example, when 901W=1 and 902W=2, 901W=3/902W=4 can be written simultaneously.

Copy destination channel upper limit

« «

Copy execution

Sets and reads the copy destination channel upper limit in channel data copying.

(901W) value to number of channels

Executes copying and reads the copy state.

0: Execution OFF/end copy

1: Copy all data

2: Copy range, calculation and scale data

3: Copy event data

4: Copy tag data

5: Copy engineering unit data

• When writing to EEPROM is started by copy execution, the response is returned before writing is completed.

If the command (even other than the copy execution command) for writing to EEPROM is received before writing is completed, response code 31 is returned.

• When a read is carried out, “0” is always read.

Accordingly, read does not become an error response. However, it is meaningless.

• When addresses 900W to 903W contain erroneous data, not all data from 900W to 903W is written, and an error is returned.

• The data (0 to 5) to be written to 903W is not written to EPPROM. However, the data to be copied is written to

EEPROM.

• When the values of the upper and lower limits of the copy destination channel are inverted, a numerical value range error (response code 44) is returned.

Check Items in Case Communication is Disabled

1. Make sure that the RS-232C and RS-485 connections are correctly wired.

2. Make sure that the communication conditions for the SRF206/212/224 match those of the host computer.

If any one of the below settings between stations differ, communication is disabled.

Settings that can be used on the SRF206/212/224 are underlined.

Transmission speed:

Data length:

Parity:

Stop bit:

4800, 9600bps

8bits

No parity, even parity

1 stop bit, 2 stop bits

3. Make sure that the destination address of the command frame transmitted from the host computer matches the address of the

SRF206/212/224

.

The

SRF206/212/224 default address is “0”. The

SRF206/212/224 will not respond even when the destination address of the command frame is set to “00”

(30H, 30H).

4. Use the upper-case for all characters other than the device ID code (“X” or “x” on the

SRF206/212/224
