* The interval time for the controller should be set to provide a time for host computer to finish sending all data including stop bit and to switch the line to receive status for the host. If the interval time between the two is too short, the controller may send data before the host computer is ready to receive it. In this case, communication transmission can not be conducted correctly. For a successful communication sequence to occur, the controller’s interval time must match the specifications of the host computer.

When the “1: Lock” is selected at the “Lock only setting items other than SV and events

(EV1 to EV4)” in the set lock level, the communication parameters are not able to change the set values.

For the set lock level, see the Operation Manual (IMR01N12-E ) .

4.3 Communication Requirements

The controller requires the following processing times during data send/receive.

Whether the host computer is using either the polling or selecting procedure for communication, the following processing times are required for controller to send data:

- Response wait time after controller sends BCC in polling procedure

- Response wait time after controller sends ACK or NAK in selecting procedure

To switch the host computer from transmission to reception, send data must be on line. To check if data is on line, do not use the host computer’s transmission buffer but confirm it by the shift register.

Whether the host computer is using either the polling or selecting procedure for communication, the following processing times are required for the controller to send data:

- Response wait time after the controller sends BCC in polling procedure

- Response wait time after the controller sends ACK or NAK in selecting procedure

A transmission error may occur with the transmission line disconnected, shorted or set to the high-impedance state. In order to prevent the above error, it is recommended that the fail-safe function be provided on the receiver side of the host computer. The fail-safe function can prevent a framing error from its occurrence by making the receiver output stable to the MARK (1) when the transmission line is in the high-impedance state.

16

5. RKC COMMUNICATION PROTOCOL

The HA430/HA930 (hereafter, called controller) uses the polling/selecting method to establish a data link. The basic procedure is followed ANSI X3.28 subcategory 2.5, A4 basic mode data transmission control procedure (Fast selecting is the selecting method used in this controller).

z The polling/selecting procedures are a centralized control method where the host computer controls the entire process. The host computer initiates all communication so the controller responds according to queries and commands from the host.

z The code use in communication is 7-bit ASCII code including transmission control characters.

The transmission control characters are EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX

(02H) and ETX (03H). The figures in the parenthesis indicate the corresponding hexadecimal number.

5.1 Polling

Polling is the action where the host computer requests one of the connected controllers to transmit data. An example of the polling procedure is shown below:

5. RKC COMMUNICATION PROTOCOL

5.1.1 Polling procedures

(1) Data link initialization

Host computer sends EOT to the controllers to initiate data link before polling sequence.

(2) Data sent from host computer - Polling sequence

The host computer sends the polling sequence in the following two types of formats:

• Format in which no memory area number is specified, and

• Format in which the memory area number is specified.

To be sent in this format for any identifier not corresponding to the memory area.

1.

3.

Address Identifier

4.

ENQ

Example:

0 1 M 1 ENQ

To be sent in this format for any identifier corresponding to the memory area.

1.

Address Memory area number

1. Address (2 digits)

2.

3.

Identifier

4.

ENQ

Example:

S

The device address specifies the controller to be polled and each controller must have its own unique device address.

Specify 00 not to omit device address in RS-232C specification.

The polling address which transmitted a message once becomes effective so long as data link is not initialized by transmit and receive of EOT.

For details, see 4.2 Setting the Communication Parameters (P. 11) .

18


2. Memory area number (3 digits)

This is the identifier to specify the memory area number. It is expressed by “K01” to “K16” to each memory area number (from 1 to 16). When one column of memory area number (1 to 9) is specified, it can be specified with “K1” to “K9.” In addition, if the memory area number is assigned with “K0” or “K00,” this represents that control area is specified.

The memory area now used for control is called “Control area.”

If the memory area number is not specified when polling the identifier corresponding to the memory area, this represents that the control area is specified.

If any identifier not corresponding to the memory area is assigned with a memory area number, this memory area number is ignored.

3. Identifier (2 digits)

The identifier specifies the type of data that is requested from the controller. Always attach the

ENQ code to the end of the identifier.

For details, see 5.4 Communication Items List (P. 32) .

4. ENQ

The ENQ is the transmission control character that indicates the end of the polling sequence.

The ENQ must be attached to the end of the identifier.

The host computer then must wait for a response from the controller.

(3) Data sent from the controller

If the polling sequence is received correctly, the controller sends data in the following format:

1.

2.

3.

4.

5.

STX Identifier Data ETX BCC

1. STX

STX is the transmission control character which indicates the start of the text transmission

(identifier and data).


The identifier indicates the type of data (measured value, status and set value) sent to the host computer.

Data which is indicated by an identifier of the controller, consisting of channel numbers, data, etc. It is expressed in decimal ASCII code including a minus sign ( − ) and a decimal point.

Data is not zero-suppressed.

Only Model codes (ID) , the number of data digits (length) is 32 digits.

Memory area soak time monitor and area soak time become the following data:

• When data range is 0 hour 00 minute 00 second to 9 hours 59 minutes 59 seconds:

Data range is 0:00:00 to 9:59:59, punctuation of time unit is expressed in colon (:).

• When data range is 0 minute 00.00 second to 9 minutes 59.99 seconds:

Data range is 0:00.00 to 9:59.99, punctuation of time unit is expressed in colon (:)

and period (.).

4. ETX

ETX is a transmission control character used to indicate the end of text transmission.

5. BCC

BCC (Block Check Character) detects error by using horizontal parity (even number).

Calculation method of BCC: Exclusive OR all data and characters from STX through ETX, not including STX.

Example:

STX 1 0 0 1 ETX

4DH 31H 30H 30H 31H 30H 30H 2EH 30H 03H Hexadecimal numbers

BCC ＝ 4DH ⊕ 31H ⊕ 30H ⊕ 30H ⊕ 31H ⊕ 30H ⊕ 30H ⊕ 2EH ⊕ 30H ⊕ 03H ＝ 50H

( ⊕ : Exclusive OR )

Value of BCC becomes 50H.

(4) EOT sent from the controller (Ending data transmission from the controller)

In the following cases, the controller sends EOT to terminate the data link:

• When the specified identifier is invalid

• When there is an error in the data type

• When data is not sent from the host computer even if the data link is initialized

• When all the data has been sent

(5) No response from the controller

The controller will not respond if the polling address is not received correctly. It may be necessary for the host computer to take corrective action such as a time-out.

20


(6) ACK (Acknowledgment)

An acknowledgment ACK is sent by the host computer when data received is correct. When the controller receives ACK from the host computer, the controller will send any remaining data of the next identifier without additional action from the host computer.

For the identifier, see 5.4 Communication Items list (P. 32) .

When host computer determines to terminate the data link, EOT is sent from the host computer.

(7) NAK (Negative acknowledge)

If the host computer does not receive correct data from the controller, it sends a negative acknowledgment NAK to the controller. The controller will re-send the same data when NAK is received. This cycle will go on continuously until either recovery is achieved or the data link is corrected at the host computer.

(8) No response from host computer

When the host computer does not respond within approximately three seconds after the controller sends data, the controller sends EOT to terminate the data link. (Time out: 3 seconds)

(9) Indefinite response from host computer

The controller sends EOT to terminate the data link when the host computer response is indefinite.

(10) EOT (Data link termination)

The host computer sends EOT message when it is necessary to suspend communication with the controller or to terminate the data link due lack of response from the controller.

5.2.1 Selecting procedures

(1) Data link initialization

Host computer sends EOT to the controllers to initiate data link before selecting sequence.

(2) Sending selecting address from the host computer

Host computer sends selecting address for the selecting sequence.

This data is a device address of the controller to be selected and must be the same as the device address set value in item 4.2 Setting the Communication Parameters (P. 11) .

Specify 00 not to omit device address with the RS-232C specification.

As long as the data link is not initialized by sending or receiving EOT, the selecting address once sent becomes valid.

IMR01N13-E2

23


(3) Data sent from the host computer

The host computer sends data for the selecting sequence with the following format:

When no memory area number is specified

2.

3.

Identifier ETX

When the memory area number is specified

1.

2.

Memory area number

Identifier

3.

ETX

For the STX, ETX and BCC, see 5.1 Polling (P. 17) .

1. Memory area number (3 digits)

This is the identifier to specify the memory area number. It is expressed by “K01” to “K16” to each memory area number (from 1 to 16). When one column of memory area number (1 to 9) is specified, it can be specified with “K1” to “K9.” In addition, if the memory area number is assigned with “K0” or “K00,” this represents that control area is specified.

The memory area now used for control is called “Control area.”

If the memory area number is not specified when selecting the identifier corresponding to the memory area, selecting is made to the memory area.

If any identifier not corresponding to the memory area is assigned with a memory area number, this memory area number is ignored.


The identifier specifies the type of data that is requested from the controller, such as set value.


3. Data

Data which is indicated by an identifier of the controller. It is expressed in decimal ASCII code including a minus sign ( − ) and a decimal point. The channel number can be zero-suppressed.

The number of digits varies depending on the type of identifier. (Within 7 digits)

Area soak time set data as the following:

• When data range is 0 hour 00 minute 00 second to 9 hours 59 minutes 59 seconds:

Data range is 0:00:00 to 9:59:59, punctuation of time unit is expressed in colon (:).

• When data range is 0 minute 00.00 second to 9 minutes 59.99 seconds:

Data range is 0:00.00 to 9:59.99, punctuation of time unit is expressed in colon (:) and period (.).

In addition to above, when minute and second data are set in more than 60, become as the following:

Example: 0: 65.00 (0 minute 65.00 seconds) → 1:05.00 (1 minute 05.00 seconds)

1: 65:00 (1 hour 65 minutes 00 second) →

2:05:00 (2 hours 05 minutes 00 second)

24


The data that receipt of letter is possible

• Data with numbers below the decimal point omitted or zero-suppressed data can be received.

(Number of digits: Within 7 digits)

<Example> When data send with − 001.5, − 01.5, − 1.5, − 1.50, − 1.500 at the time of − 1.5, controller can receive a data.

• When the host computer sends data with decimal point to item of without decimal point, the controller receives a message with the value that cut off below the decimal point.

<Example> When setting range is 0 to 200, the controller receives as a following.

Send data 0.5 100.5

Receive data 0 100

• The controller receives value in accordance with decided place after the decimal point. The value below the decided place after the decimal point is cut off.

<Example> When setting range is − 10.00 to + 10.00, the controller receives as a following.

Send data

Receive data

− .5

− 0.50

+

−

.

− .

Plus sign and the data that gained plus sing

Only minus sign (there is no figure)

Only decimal point (period)

Only minus sign and decimal point (period)

(4) ACK (Acknowledgment)

An acknowledgment ACK is sent by the controller when data received is correct. When the host computer receives ACK from the controller, the host computer will send any remaining data. If there is no more data to be sent to the controller, the host computer sends EOT to terminate the data link.

IMR01N13-E2

25


(5) NAK (Negative acknowledge)

If the controller does not receive correct data from the host computer, it sends a negative acknowledgment NAK to the host computer. Corrections, such as re-send, must be made at the host computer. The controller will send NAK in the following cases:

• When an error occurs on communication the line (parity, framing error, etc.)

• When a BCC check error occurs

• When the specified identifier is invalid

• When receive data exceeds the setting range

• When receive data is the identifier of RO (read only)

(6) No response from controller

The controller does not respond when it can not receive the selecting address, STX, ETX or BCC.

(7) EOT (Data link termination)

The host computer sends EOT when there is no more data to be sent from the host computer or there is no response from the controller.

5.3 Examples of Polling and Selecting Check Programs

The following is the sample program for NEC PC-9800 series computers in BASIC language for carrying out polling and selecting checking by RS-232C specification. There will be some differences in the computer languages according to the type of computer. Before executing the program, confirm that there is no mistake in the wiring of the communications cable and check that the instrument data bit configuration is set to 8 for data bit and Without for parity bit. In addition, the communications speed setting should be set to match the host computer speed setting.

When this program example is used for RS-485, the automatic sending/receiving selection type of RS-232C/RS-485 is required.

(Recommended: CD485, CD485/V manufactured by Data Link, Inc. or equivalent.)

MODBUS COMMUNICATION PROTOCOL

The master controls communication between master and slave. A typical message consists of a request (query message) sent from the master followed by an answer (response message) from the slave. When master begins data transmission, a set of data is sent to the slave in a fixed sequence.

When it is received, the slave decodes it, takes the necessary action, and returns data to the master.

6.1 Message Format

The message consists of four parts: slave address, function code, data, and error check code which are always transmitted in the same sequence.

Slave address

Function code

Data

Error check CRC-16

Message format

The slave address is a number from 1 to 99 manually set at the controller address setting switch located at the front of the controller.

For details, see 4.2

Setting the Communication Parameters (P. 11) .

Although all connected slave units receive the query message sent from the master, only the slave with the slave address coinciding with the query message will accept the message.

The function codes are the instructions set at the master and sent to the slave describing the action to be executed. The function codes are included when the slave responds to the master.

For details, see 6.2 Function Code (P. 56) .

The data to execute the function specified by the function code is sent to the slave and corresponding data returned to the master from the slave.

For details, see 6.6 Message Format (P. 61) , 6.7 Data Configuration (P. 65) and 6.8 Data

Map List (P. 70) .

An error checking code (CRC-16: Cyclic Redundancy Check) is used to detect an error in the signal transmission.

For details, see 6.5 Calculating CRC-16 (P. 58) .

Less than 24 bits’ time *

CRC-16 (Cyclic Redundancy Check)

* When sending a command message from the master, set intervals of data configuring one message to time shorter than the 24 bits’ time or the 24 bits’ time plus a few milliseconds. If time intervals become time longer than the 24 bits’ time or the 24 bits’ time plus a few milliseconds, the relevant slave assumes that message sending from the master is terminated to deform the message format. As a result, the slave does not make a response.

56


6.4 Slave Responses

(1) Normal response

• In the response message of the Read Holding Registers, the slave returns the read out data and the number of data items with the same slave address and function code as the query message.

• In the response message of the Preset Single Register, the slave returns the same message as the query message.

• In the response message of the Diagnostics (Loopback test), the slave returns the same message as the query message.

• In the response message of the Preset Multiple Registers, the slave returns the slave address, the function code, starting number, and number of holding registers in the multi-query message.

(2) Defective message response

• If the query message from the master is defective, except for transmission error, the slave returns the error response message without any action.

Error response message

• If the self-diagnostic function of the slave detects an error, the slave will return an error response message to all query messages.

Self-diagnostic error response

IMR01N13-E2

57


(3) No response

The slave ignores the query message and does not respond when:

• The slave address in the query message does not coincide with any slave address settings.

• The CRC code of the master does not coincide with that of the slave.

• Transmission error such as overrun, framing, parity and etc., is found in the query message.

• Data time interval in the query message from the master exceeds 24 bit’s time. *

* When this case is operated, there is when the slave does not sometimes make a response.

6.5 Calculating CRC-16

The Cyclic Redundancy Check (CRC) is a 2 byte (16-bit) error check code. After constructing the data message, not including start, stop, or parity bit, the master calculates a CRC code and appends this to the end of the message. The slave will calculate a CRC code from the received message, and compare it with the CRC code from the master. If they do not coincide, a communication error has occurred and the slave does not respond.

The CRC code is formed in the following sequence:

1. Load a 16-bit CRC register with FFFFH.

2. Exclusive OR ( ⊕ ) the first byte (8 bits) of the message with the CRC register. Return the result to the CRC register.

3. Shift the CRC register 1 bit to the right.

4. If the carry flag is 1, exclusive OR the CRC register with A001 hexadecimal and return the result to the CRC register. If the carry flag is 0, repeat step 3 .

5. Repeat step 3 and 4 until there have been 8 shifts.

6. Exclusive OR the next byte (8 bits) of the message with the CRC register.

7. Repeat step 3 through 6 for all bytes of the message (except the CRC).

8. The CRC register contains the 2 byte CRC error code. When they are appended to the message, the low-order byte is appended first, followed by the high-order byte.

6.7.2 Caution for handling communication data

• In this communication, the variable is handled as 4 bytes data.

• In this communication, one variable use two register addresses (Address of high-order word,

Address of low-order word).

• Tow-word data is read and written from low-order words to high-order words in order.

If Modbus 1 is selected in the communication protocol selection of the engineering mode, data is read and written from high-order words to low-order words in order.

• In this communication, the variables that memory area includes handles different address with for control area and for setting area.

• There is the following constraint in writing data in order to treat the variable as 4 bytes data in this communication.

− It is not possible to write only of high-order word. The communication response becomes normal response, but do not writing.

− A writing only of low-order word does sign extend and does it.

Example 1: When did a writing only of “0020H” in low-order word.

The controller interprets high-order word as “0000H.”

Example 2: When did a writing only of “FFFFH ( − 1) ” in low-order word.

The controller interprets high-order word as “FFFFH.”

• Addresses in which data (holding register) is accessible are from 0000H to 00ADH, from 0200H to

031DH, and from 0500H to 0535H. If any address other than 0000H to 00ADH, 0200H to 031DH, and 0500H to 0535H is accessed, an error response message returns.

• Read data of unused item is a default value.

• Any attempt to write to an unused item is not processed as an error. Data can not be written into an unused item.

• If data range or address error occurs during data writing, it is not processed as an error. Except the data that error occurred, normal data is written in data register. Therefore, it is necessary to confirm data after the end of setting data.

• Communication data includes data that becomes RO (read only) depending on the specification. No error occurs even if data is written when set to RO. However in this case, no data is written.

For details, see 6.8 Data Map List (P. 70) .

• Send the next command message at time intervals of 30 bits after the master receives the response message.

Functional description:

Autotuning (AT):

Autotuning (AT) automatically measures, calculates and sets the optimum PID (PI) constants. The following conditions are necessary to carry out autotuning and the conditions which will cause the autotuning to stop.

Requirements for AT start:

Start the autotuning when all following conditions are satisfied:

• Operation mode conditions are as follows:

− Auto/Manual transfer → Auto mode

− Remote/Local transfer → Local mode

− PID/AT transfer → PID control

− RUN/STOP transfer → Control RUN

• The measured value (PV) is not underscale or overscale.

• The output limiter high limit is 0.1 % or higher and the output limiter low limit is 99.9 % or less.

When the autotuning is finished, the controller will automatically returns to PID (PI) control.

Requirements for AT cancellation:

The autotuning is canceled if any of the following conditions are exist:

• When the temperature set value (SV) is changed.

• When the control area is changed.

• When the output limiter high limit or the output limiter low limit is changed.

• When the PV bias, the PV digital filter, or the PV ratio is changed.

• When the Auto/Manual mode is changed to the Manual mode.

• When the Remote/Local mode is changed to the Remote mode.

• When the measured value (PV) goes to underscale or overscale.

• When the power failure occurs.

• When the instrument is in the FAIL state.

• When the PID/AT transfer is changed to the PID control.

• When the RUN/STOP mode is changed to the control STOP.

If the AT is canceled, the controller immediately changes to PID (PI) control.

The PID (PI) values will be the same as before AT was activated.

LBA Function

Control loop break alarm (LBA):

The control loop break alarm (LBA) function is used to detect a load (heater) break or a failure in the external actuator (power controller, magnet relay, etc.), or a failure in the control loop caused by an input (sensor) break. The LBA function is activated when control output reaches 0 % (low limit with output limit function) or 100 % (high limit with output limit function). LBA monitors variation of the measured value (PV) for the length of LBA time. When the LBA time has elapsed and the PV is still within the alarm determination range, the LBA will be ON.

[Alarm action]

LBA determination range: Temperature input: 2 ° C [2 ° F] fixed

Voltage/current input: 0.2 % fixed

• When the output reaches 0 % (low limit with output limit function)

For direct action: When the LBA time has passed and the PV has not risen beyond the alarm determination range, the alarm will be turned on.

For reverse action: When the LBA time has passed and the PV has not fallen below the alarm determination range, the alarm will be turned on.

• When the output exceeds 100 % (high limit with output limit function)

For direct action: When the LBA time has passed and the PV has not fallen below the alarm determination range, the alarm will be turned on.

For reverse action: When the LBA time has passed and the PV has not risen beyond the alarm determination range, the alarm will be turned on.

If the autotuning function is used, the LBA time is automatically set twice as large as the integral time. The LBA setting time will not be changed even if the integral time is changed.

LBA Deadband function:

The LBA may malfunction due to external disturbances. To prevent malfunctioning due to external disturbance, LBA deadband (LBD) sets a neutral zone in which LBA is not activated. When the measured value (PV) is within the LBD area, LBA will not be activated. If the LBD setting is not correct, the LBA will not work correctly.

If the LBA function detects an error occurring in the control loop, but cannot specify the location, a check of the control loop in order. The LBA function does not detect a location which causes alarm status. If LBA alarm is ON, check each device or wiring of the control loop.

When AT function is activated or the controller is in STOP mode, the LBA function is not activated.

If the LBA setting time does not match the controlled object requirements, the LBA setting time should be lengthened. If setting time is not correct, the LBA will malfunction by turning on or off at inappropriate times or not turning on at all.

While the LBA is ON (under alarm status), the following conditions cancel the alarm status and LBA will be OFF.

• The measured value (PV) rises beyond (or falls below) the LBA determination range within the LBA time.

• The measured value (PV) enters within the LBA deadband.

When the setting change rate limiter is used, the SV will also ramp up or ramp down by the function at power-on and operation mode change from STOP to RUN.

If the autotuning (AT) function is activated while the SV is ramping up or ramping down by the setting change rate limiter, AT will starts after the SV finishes ramp-up or ramp-down by the limiter, and the controller is in PID control mode until AT starts.

When the value of setting change rate limiter is changed during normal operation, the ramp-up or ramp-down rate will be changed unless the SV already has finished ramp-up or ramp-down by the function.

If the rate of setting change limiter is set to any value other than “0.0: OFF (Unused),” the event re-hold action to be taken by a set value (SV) change becomes invalid.

• As data is being written to the EEPROM when the EEPROM storage mode

is selected “0: Set values are store to the EEPROM when set values are

changed,” do not turn the power off. If turned off, no set values are stored.

• If the EEPROM storage mode is changed after “0: Set values are store to the

EEPROM when set values are changed” is changed to “1: Not set values are

store to the EEPROM when set values are changed,” 0 is set (mismatch).

As the set value changed is not backup, select the backup mode if necessary.

1: The content of the EEPROM coincides with that of the RAM.

The contents of the RAM match with those of the EEPROM.

EEPROM storage mode


EB




It is set whether the data storage in the non-volatile memory (EEPROM) is executed or not.


Digits: 7

Data range: 0: Set values are store to the EEPROM when set values are changed.

1: Not set values are store to the EEPROM when set values are changed.


When the memory is used to frequently change the set value via communication, select

“1: Not set values are store to the EEPROM when set values are changed.”

For the following case, data is stored into the EEPROM regardless of the EEPROM mode setting.

• When the data is changed through key operation

• Data written into the controller by specifying the memory area number

The non-volatile memory (EEPROM) has limitations on the number of memory rewrite times. If “1: Not set values are store to the EEPROM when set values are changed” is selected as the EEPROM storage mode, all of the set values changed are not written to the

EEPROM and thus a problem of limitations on the number of memory rewrite times can be solved.

When selecting any EEPROM storage mode, take notice of the following.

• If power failure occurs while “1: Not set values are store to the EEPROM when set values

are changed” is selected, the set value returns to the value before the storage mode is

selected.

• If “1: Not set values are store to the EEPROM when set values are changed” is changed

to “0: Set values are store to the EEPROM when set values are changed,” all of the set

values at that time are stored to the EEPROM. If necessary to backup the final value of

each set item, select “0: Set values are store to the EEPROM when set values are

changed.”

• When the power is turned on, “0: Set values are store to the EEPROM when set values are

changed” is always set.

An output logic becomes OR output when two or more output functions are assigned to one output.

When three transmission outputs are selected, the transmission outputs are automatically assigned to OUT1 through OUT3 and it has priority over the Output Logic Selection. To select Manipulated Output Value of Input 1 or Input 2 as output type of OUT1, OUT2 or

OUT3, select “4: Input 1_manipulated output value (MV)” or “8: Input 2_manipulated output value (MV)” at the parameters of Transmission Output Type Selection.

The control loop break alarm (LBA) function is used to detect a load (heater) break or a failure in the external actuator (magnet relay, etc.), or a failure in the control loop caused by an input (sensor) break.

The LBA function is activated when control output reaches 0 % (low limit with output limit function) or 100 % (high limit with output limit function). LBA monitors variation of the measured value (PV) for the length of LBA time. When the LBA time has elapsed and the PV is still within the alarm determination range, the LBA will be ON.

[Alarm action]

The LBA function produces the alarm when any of the following conditions occurs.

LBA determination range: Temperature input: 2 ° C [2 ° F] fixed

Voltage/current input: 0.2 % fixed

• When the control output reaches 0 % (low limit with output limit function)

For direct action: When the LBA time has passed and the PV has not risen beyond the alarm determination range, the alarm will be turned on.

For reverse action: When the LBA time has passed and the PV has not fallen below the alarm determination range, the alarm will be turned on.

• When the output exceeds 100 % (low limit with output high function)

For direct action: When the LBA time has passed and the PV has not fallen below the alarm determination range, the alarm will be turned on.

For reverse action: When the LBA time has passed and the PV has not risen beyond the alarm determination range, the alarm will be turned on.


IMR01N13-E2 157



If the autotuning function is used, the LBA time is automatically set twice as large as the integral time. The LBA setting time will not be changed even if the integral time is changed.

When AT function is activated or the controller is in STOP mode, the LBA function is not activated.

The LBA function does not detect a location which causes alarm status. If LBA alarm is ON, check each device or wiring of the control loop.

While the LBA is ON (under alarm status), the following conditions cancel the alarm status and LBA will be OFF.

• The measured value (PV) rises beyond (or falls below) the LBA determination range within the LBA time.

• The measured value (PV) enters within the LBA deadband.

Example: When Re-hold action is OFF and event output type is deviation, the event output is produced due to the set value change. The Re-hold action suppresses the alarm output until the measured value has entered the non-event range again.

The output change rate limiter limits the variation of manipulated output (MV) per second. This function is suitable for an application in which a sudden MV change is not acceptable.

[Example]

The output change rate limiter is effective

• The MV reaches 100 % when the power is turned on to the controller and such a sudden output change is not acceptable in the application.

• A sudden output change occurs at the SV change and it is not acceptable in the application.

Sudden change in the output at power-up, set value change or by disturbance

The output changes at specific rates set by Output Change Rate Limiter (up) even under the situations where a sudden output change would occur without Output Change Rate Limiter function. There is also independent Output Change Rate Limiter (down).

Set the amount of increase given to the operation output in the percentage of span for each second.

If the Output Change Rate is set smaller, it will cause slow control response and affect

Derivative action.

When the Output Change Rate Limiter is used, you may not be able to obtain appropriate

PID constants by autotuning.

The Output Change Rate Limiter is particularly effective when a sudden MV change may create uncontrollable situation cause a large current flow. Also, it is very effective current output or voltage output is used as control output.

Digits: 7


Factory set value: Input 1_AT differential gap time: 0.10

Input 2_AT differential gap time: 0.10



In order to prevent the output from chattering due to the fluctuation of a measured value (PV) caused by noise during autotuning, the output on or off state is held until “AT differential gap time” has passed after the output on/off state is changed to the other. Set “AT differential gap time” to “1/100 × Time required for temperature rise.”

Example:

A: AT cycle time when the AT differential gap time is set to 0.00 second

The output chatters due to the fluctuation of the measured value (PV) caused by noise, and autotuning function is not able to monitor appropriate cycles to calculate suitable PID values.

B: AT cycle time when the AT differential gap time is set to “Time corresponding to 0.25 cycles.”

The fluctuation of a measured value (PV) caused by noise is ignored and as a result autotuning function is able to monitor appropriate cycles to calculate suitable PID values.
