1. OUTLINE

1.1 Features

This chapter describes features, package contents and model code, etc. The module type controller has the following features:

Module type controller SRZ interfaces with the host computer via Modbus or RKC communication protocols. The SRZ sets all of the data items via communication (The communication interface used for both protocols is RS-485.). Therefore before operation, it is necessary to set value of each data item via communication.

 Common to both Z-TIO and Z-DIO module

 A user can select RKC communication or Modbus.  When each module is connected, the power and communication lines are connected internally within the

modules, and thus it is only necessary to wire one module to the power terminal and communication terminal; there is no need to individually wire each module to the terminals. This reduces the amount of wiring needed.

 Compact size

Terminal type: depth 85 mm, Connector type: depth 79 mm

 Z-TIO module (Z-TIO-A, Z-TIO-B)

 The Z-TIO module is a temperature control module equipped with either two or four control channels.  The measured input is a universal input that supports thermocouple input, resistance temperature sensor

input, voltage input, current input, and feedback resistance input.

 The input type can be specified separately for each channel, and different input types can be combined.  Output types are relay contact output, voltage pulse output, voltage output, current output, open collector output, and

triac output. Output types are specified when the order is placed, and a different output type can be specified for each channel.

 4CH Z-TIO module can have 4 CT (current transformer) inputs.  Up to 16 Z-TIO modules can be connected.

[The maximum number of SRZ modules (including other function modules) on the same communication line is 31.]

 Z-DIO module (Z-DIO-A)

 The Z-DIO module is an event input/output module equipped with digital inputs and outputs (DI8 points

/DO8 points).

 DI signal assignment enables switching of various mode states and memory areas of the Z-TIO module.  DO signal assignment enables output of the event result of the Z-TIO module to the event output (DO),

and output of the DO manual output state of the Z-DIO module.

 Up to 16 Z-DIO modules can be connected.

[The maximum number of SRZ modules (including other function modules) on the same communication line is 31.]

For reference purposes, the Modbus protocol identifies the host computer as master, each module of SRZ as slave.

For details of the Z-CT module, refer to Z-CT Instruction Manual (IMS01T21-E).

4.1 Wiring Cautions

This chapter describes wiring cautions, wiring layout and wiring of terminals.

To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure that the wiring is correct before applying power to the instrument.

WARNING

 For thermocouple input, use the appropriate compensation wire.  For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires

(3-wire system).

 Signal connected to Voltage input and Current input shall be low voltage defined as “SELV” circuit per

IEC 60950-1.

 To avoid noise induction, keep input/output signal wires away from instrument power line, load lines and

power lines of other electric equipment.

 If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

 Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise

reduction.

 Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise

filter output and the instrument power supply terminals to achieve the most effective noise reduction.

 Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness

of the noise filter.

 Allow approximately 8 seconds for contact output when the instrument is turned on. Use a delay relay

when the output line is used for an external interlock circuit.

 Power supply wiring must be twisted and have a low voltage drop.  For an instrument with 24 V power supply input, supply power from a “SELV” circuit defined as IEC

60950-1.

 A suitable power supply should be considered in end-use equipment. The power supply must be in

compliance with a limited-energy circuits (maximum available current of 8 A).

 Supply the power to only one of the joined modules. When power is supplied to any one of the joined

modules, all of the joined modules will receive power.

 Select the power capacity which is appropriate for the total power consumption of all joined modules and

the initial current surge when the power is turned on.

Power consumption (at maximum load): 140 mA max. (at 24 V DC) [Z-TIO module (4CH type)] 80 mA max. (at 24 V DC) [Z-TIO module (2CH type)] 70 mA max. (at 24 V DC) [Z-DIO module] Rush current: 10 A or less

 For the terminal type module, use t he specif ied solder less term inals . Only these specified solderless terminals

can be used due to the insulation between the terminals.

When all outputs are continuous output (current output, voltage output) or voltage pulse output, there is no

need for isolation between outputs. There is also no need for isolation between each output and the power supply, and no need for isolation between each output and communication.

When the output type is relay contact output or triac output, isolation is required between this output and

4.2 Connecting Precautions

To prevent electric shock or instrument failure, turn off the power before connecting or disconnecting the instrument and peripheral equipment.

 Connect connectors correctly in the right position. If it is forcibly pushed in with pins in the wrong

positions, the pins may be bent resulting in instrument failure.

 When connecting or disconnecting the connectors, do not force it too far to right and left or up and down,

but move it on the straight. Otherwise, the connector pins may be bent, causing instrument failure.

 When disconnecting a connector, hold it by the connector itself. Disconnecting connectors by yanking on

their cables can cause breakdowns.

WARNING

 To prevent malfunction, never touch the contact section of a connector with bare hands or with hands

soiled with oil or the like.

 To prevent damage to cables, do not bend cables over with excessive force.

5.3 Operating Precautions

Check the following items before starting operation, then turn on the power.

 Power ON

When first powered on, the unit starts with the operation mode set to “Control” and the RUN/STOP switch set to STOP (control is stopped) (FAIL/RUN display lamp: lights green). When the RUN/STOP switch is switched from STOP to RUN, operation begins. [Factory set value: STOP]

 Action at input error

If the input signal wiring is disconnected or short-circuited (RTD input and Feedback resistance input only), the instrument determines that burnout has occurred.

 Burnout direction

Upscale: Thermocouple Voltage (low) input

, RTD input (at input break), Feedback resistance input (at input break),

Downscale: Thermocouple 1, RTD input (at short-circuited), Feedback resistance input

(at short-circuited), Voltage (low) input, Voltage (high) input 2, Current input 2

For the thermocouple input or the voltage (low) input, upscale or downscale can be selected by Engineering mode. (Factory set value: Upscale)

For the voltage (high) input or the current input, the display becomes indefinite (display of about zero value).

 Output at input error

Control output: According to the contents set by “Action (high/low) at input error” Event output: According to the contents set by “Event action at input error”

 Checking the each parameter

The settings for the SV and all parameters should be appropriate for the controlled system. There are parameters in Engineering setting which can not be changed when the controller is in RUN mode.

Change the RUN/STOP mode from RUN to STOP when a change for the parameters in Engineering setting is necessary.

For details of the each parameter, refer to 8. COMMUNICATION DATA DESCRIPTION

(P. 8-1).

 Operation when power failure

A power failure of 4 ms or less will not affect the control action. When a power failure of more than 4 ms occurs the instrument assumes that the power has been turned off. When the power returns, the operation of instrument will be re-starts in accordance with the content selected by Hot/Cold start.

For details of Hot/Cold start, refer to Hot/Cold start (P. 8-92).

 Event hold action

 The event action is activated when the power is turned on or when transferred from STOP mode to RUN

mode.

 The event re-hold action is activated when not only the SV is changed, but also the power is turned on or

when transferred from STOP mode to RUN mode.

 Fail-safe

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.

6.1 Polling

RKC communication uses the Polling/Selecting method to establish a data link. The basic procedure is followed ANSI X3.28-1976 subcategories 2.5 and B1 basic mode data transmission control procedure (Fast selecting is the selecting method used in SRZ).

 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.

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

Transmission control characters used in SRZ: EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX (02H), ETB (17H), ETX (03H) ( ): Hexadecimal

Data send/receive sta te c a n b e m onit or ed by us i ng our c ommunication tool (WinUCI-SRZ, PROTEM2).

The communication tool (WinUCI-SRZ, PROTEM2) can be downloaded from the official RKC

website:

http://www.rkcinst.com/.

6.1.1 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.

 When no Memory area number is specified

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

number

Identifier Address

1. Address (2 digits)

This data is a module address of the SRZ for polled and must be the same as the module address set value in item 5.1 Module Address Setting (P. 5-2).

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

2. Memory area number (2 digits)

This is the identifier to specify the Memory area number. It is expressed by K1 to K8 to each Memory area number (from 1 to 8). If the Memory area number is assigned with K0, 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.

Example:

3. Identifier (2 digits)

The identifier specifies the type of data that is requested from the SRZ. Always attach the ENQ code to the end of the identifier.

Refer to 6.4 Communication Data List (P. 6-13).

4. ENQ

The ENQ is the transmission control ch aract er that ind icates t he end of the po lling sequen ce. The host computer then must wait for a response from the SRZ.

(3) Data sent from the SRZ

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

Identifier Data BCCETBSTX

Identifier Data BCCETXSTX

If the length of send data (from STX to BCC) exceeds 136 bytes, it is divided into blocks by ETB.

In this case, the succeeding divided data is sent after STX.

1. STX

STX is the transmission control character which indicates the start of the text transmission (identifier and data).

2. Identifier (2 digits)

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

3.2. 6.4.1.

3.2. 6.5.1.

Refer to 6.4 Communication Data List (P. 6-13).

3. Data

Data which is indicated by an identifier of this instrument, consisting of channel numbers, data, etc. Each channel number and data are delimited by a space (20H). The data and the next channel number are delimited by a comma (2CH).

 Channel number: 2-digit ASCII code, not zero-suppressed. Channels without channel numbers

may exist depending on the type of identifier.

 Data: ASCII code, zero-suppressed with spaces (20H). The number of digits varies

depending on the type of identifier.

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

 When data range is 0 hour 00 minute to 99 hours 59 minutes:

Data range is 0:00 to 99:59, punctuation of time unit is expressed in colon “: (3AH).”

 When data range is 0 minute 00 second to 199 minutes 59 seconds:

Data range is 0:00 to 199:59, punctuation of time unit is expressed in colon “: (3AH).”

4. ETB

Transmission control character indicating the end of the block.

5. ETX

Transmission control character indicating the end of the text.

6. 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 ETB or ETX, not including STX.

Example:

STX M 1 0 1 1 5 0 . 0 ETX BCC

4DH 31H 30H 31H 20H 20H 31H 35H 30H 2EH 30H 03H

BCC = 4DH  31H  30H  31H  20H  20H  31H  35H  30H  2EH  30H  03H = 54H ( : Exclusive OR) Value of BCC becomes 54H

(4) EOT send (Ending data transmission from the SRZ)

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

 When the specified identifier is invalid  When there is an error in the data format  When all the data has been sent

(5) No response from the SRZ

The SRZ 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.

IMS01T04-E6

6-5

Page 64

6. RKC COMMUNICATION

(6) ACK (Acknowledgment)

An acknowledgment ACK is sent by the host computer when data received is correct. When the SRZ receives ACK from the host computer, the SRZ will send any remaining data of the next identifier without additional action from the host computer.  When ACK was sent in succession for Z-TIO module, identifier data item down to “Communication

switch for logic” in the communication identifier list are sent.

 When ACK was sent in succession for Z-DIO module, identifier data item down to “DO minimum

ON/OFF time of proportioning cycle” in the communication identifier list are sent.

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 SRZ, it sends a negative acknowledgment NAK to the SRZ. The SRZ 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 SRZ sends data, the SRZ sends EOT to terminate the data link (time-out time: about 3 seconds).

(9) Indefinite response from host computer

The SRZ 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 SRZ or to terminate the data link due lack of response from the SRZ.

(4) ACK (Acknowledgment)

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

(5) NAK (Negative acknowledge)

If the SRZ 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 SRZ 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 SRZ

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

(7) EOT (Data link termination)

The Engineering setting data should be set according to the application before setting any parameter related to operation. Once the Engineering setting data are set correctly, no further changes need to be made to parameters for the same application under normal conditions. If they are changed unnecessarily, it may result in malfunction or failure of the instrument. RKC will not bear any responsibility for malfunction or failure as a result of improper changes in the Engineering setting.

When attempting to poll non-existing communication data item (invalid identifier), EOT is returned from the SRZ. In case of selecting, NAK is returned from the SRZ.

7.1 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 (SRZ). 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.

Data send/receive state can be monitored by using our communication tool (PROTEM2). The communication tool (PROTEM2) can be downloaded from the official RKC website: http://www.rkcinst.com/.

7.1.1 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

 Slave address

The slave address is a number from 0 to F manually set at the module address setting switch located at the front of the function module (Z-TIO, Z-DIO, Z-CT and Z-COM).

For details, refer to 5.1 Module Address Setting (P. 5-2).

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.

 Function code

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, refer to 7.1.2 Function code (P. 7-3).

 Data

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, refer to 7.2 Register Read and Write (P. 7-8), 7.3 Data Processing Precautions (P. 7-12) and 7.6 Communication Data List (P. 7-18).

 Error check

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

For details, refer to 7.1.5 Calculating CRC-16 (P. 7-5).

* When sending a command message from the master, set intervals of data configuring one message to time shorter than the 24-bit

time. If time intervals become time longer than the 24-bit time 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.

7.1.4 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.

 If the self-diagnostic function of the slave detects an error, the slave

will return an error response message to all query messages.

 The function code of each error response message is obtained by adding

80H to the function code of the query message.

Error code Contents

1 Function code error (An unsupported function code was specified) 2 When the mismatched address is specified. 3

4 Self-diagnostic error response

 When the specified number of data items in the query message exceeds the maximum number of

data items available

 When the data written exceeds the setting range

(3) No response

Slave address Function code

Error code

Error check CRC-16

Error response message

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 time.

7.1.5 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 match, a communication error has occurred and the slave does not respond.

The CRC code is formed in the following sequence:

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

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 hex and return the result to the CRC

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.

 Example of a CRC calculation in the ‘C’ language

This routine assumes that the data types ‘uint16’ and ‘uint8’ exists. Theses are unsigned 16-bit integer (usually an ‘unsigned short int’ for most compiler types) and unsigned 8-bit integer (unsigned char). ‘z_p’ is a pointer to a Modbus message, and ‘z_messaage_length’ is its length, excluding the CRC. Note that the Modbus message will probably contain NULL characters and so normal C string handling techniques will not work.

uint16 calculate_crc（byte *z_p, unit16 z_message_length）

/* CRC runs cyclic Redundancy Check Algorithm on input z_p */ /* Returns value of 16 bit CRC after completion and */ /* always adds 2 crc bytes to message */ /* returns 0 if incoming message has correct CRC */

{

uint16 CRC= 0xffff; uint16 next; uint16 carry; uint16 n; uint8 crch, crcl;

while (z_messaage_length--) {

next = (uint16) *z_p; CRC ^= next; for (n = 0; n < 8; n++) {

carry = CRC & 1; CRC >>= 1; if (carry) {

CRC ^= 0xA001;

} } z_p++;

} crch = CRC / 256; crcl = CRC % 256 z_p [z_messaage_length++] = crcl; z_p [z_messaage_length] = crch; return CRC;

7.2 Register Read and Write

7.2.1 Read holding registers [03H]

The query message specifies the starting register address and quantity of registers to be read. The contents of the holding registers are entered in the response message as data, divided into two parts: the high-order 8-bit and the low-order 8-bit, arranged in the order of the register num bers.

Example: The contents of the four holding registers from 0000H to 0003H are the read out from slave

address 2.
