7. MODBUS 7.1 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. 7.1.

PAGE 119
7. MODBUS 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 and Diagnostics (Loopback test), the slave returns the same message as the query message.
PAGE 120
7. MODBUS 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 coincide, a communication error has occurred and the slave does not respond.

Yes Reverse with high-order byte and low-order byte of CRC Register. END The ⊕ symbol indicates an exclusive OR operation. The symbol for the number of data bits is n.
PAGE 122
7. MODBUS 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.
PAGE 123
7. MODBUS 7.2 Message Format 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 numbers. Example: The contents of the three holding registers from 006BH to 006DH are the read out from slave address 2.
PAGE 124
7. MODBUS 7.2.2 Preset single register [06H] The query message specifies data to be written into the designated holding register. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified. Example: Data is written into the holding register 00C8H of slave address 1.
PAGE 125
7. MODBUS 7.2.3 Diagnostics (Loopback test) [08H] The master’s query message will be returned as the response message from the slave. This function checks the communication system between the master and slave (SR Mini HG SYSTEM control unit).
PAGE 126
7. MODBUS 7.2.4 Preset multiple registers [10H] The query message specifies the starting register address and quantity of registers to be written. The write data is arranged in the query message with high-order 8-bit first and low-order 8-bit next. Only R/W holding registers can be specified. Example: Data is written into the two holding registers from 00C8H to 00C9H of slave address 1.

FFFFH represents −1. Data processing with decimal points Data with decimal points The Modbus protocol does not recognize data with decimal points during communication.

PAGE 130
7. MODBUS Data whose decimal point’s presence and/or position depends on input range The position of the decimal point changes depending on the input range type because the Modbus protocol does not recognize data with decimal points during communication. The following data can have one of three decimal point positions: No digit below decimal point, 1 digit below decimal point, 2 digits below decimal point For details, see Input range table (P. 107).
PAGE 131
7. MODBUS 7.3.2 Data processing precautions With Modbus protocol, the maximum number of channels per slave address is 20. The accessible data (holding register) address range is from 0000H to 1FFFH. If data exceeding the 1FFFH is accessed, an error response message is returned. Do not write data to any address which is not described in a list of data maps. Initialize the module after changing to stop the control. Read data of unused channel and undefined address is “0.

8. FUNCTIONS 8.1 Output Ratio Output ratio function multiplies value (gradient) set with output ratio in manipulated output value of master channel (Temperature control module H-TIO- ), and it is function to output the consequence as manipulated output value from slave channel (Digital output module H-DO-G). Other than H-PCP-J module, H-TIO- module and H-DO-G module are requirement to do output ratio function.
PAGE 177
8. FUNCTIONS Output ratio action Manipulated output value of master channel and slave channel are output within the output limiter range. Master channel (H-TIO module) Manipulated output value of master channel Output limiter (high limit) Output limiter (low limit) 0% PID computation result 100 % Slave channel (H-DO-G module) Manipulated output value of slave channel Output ratio set value: 2.000 Output limiter (high limit) Output ratio set value: 1.000 Output ratio set value: 0.
PAGE 178
8. FUNCTIONS Assignment of the master channels It is possible to assign the master channel corresponding to the slave channel if in the same unit. The master channel is assigned by “H-DO-G master channel setting.” H-DO-G master channel setting Setting range: 0 to The number of H-TIO- module use channel (0: Unused) Example: Setting in the following system configuration. H-PCP-J module ........................... 1 H-TIO-B module (2 channels) ....... 4 (Master channel 1 to 8) H-DO-G module (16 channels) ..

8. FUNCTIONS 8.2 Speed Control Speed control function inputs pulse from rotary encoder, and motor speed is controlled. Other than H-PCP-J module, H-SIO-A module are requirement to do speed control function.
PAGE 181
8. FUNCTIONS 8.2.1 Display scale This function scales the display range of the input value between −9999 to +10000. However, the maximum span is 10000. H-SIO-A input frequency at full scale: Sets the frequency of encoder when display scale high value (full scale) is displayed. Setting rage: 10 to 50000 Hz Display scale high: Sets the high limit value (full scale) of display scale.
PAGE 182
8. FUNCTIONS 8.2.2 Measuring method Can be selected periodic computation method or pulse count method. Periodic computation method Frequency is obtained by measuring the time required for certain pulse intervals. The number of measured pulses can be set in the pulse range of 1 to 1000 by setting divide ratio. Setting range H-SIO-A divide ratio: 1 to 1000 Example: When divide ratio is set to 3.
PAGE 183
8. FUNCTIONS 8.2.3 Output scale This function scales the output range between −9999 to +10000. H-SIO-A output scale high: Sets the value equivalent to display scale of control output high limit. Setting rage: H-SIO-A output scale low to 10000 H-SIO-A output scale low: Sets the value equivalent to display scale of control output low limit. Setting rage: −9999 to H-SIO-A output scale high Example: Output scale setting when the control output value is 9 V DC at maximum motor speed of 1000 mm/min.
PAGE 184
8. FUNCTIONS 8.2.5 Controls This instrument controls with open loop control or PID control (closed loop control). (1) Open loop control In a deviation between the motor speed measured value and set value is larger than the H-SIO-A control range set value, or the H-SIO-A open/closed loop control transfer is “1: Open loop control,” the instrument is in open loop control, thereby outputting a constant control output value corresponding to the motor speed set value.
PAGE 185
8. FUNCTIONS (2) PID Control (Closed loop control) If a deviation between the motor speed measured value and set value is within the control range set value, and the H-SIO-A open/closed loop control transfer is “0: Closed loop control,” the instrument performs PID control. PI control (factory set value, derivative time: 0) is recommended in case of speed control.
PAGE 186
8. FUNCTIONS Control response parameters This is the function of enabling the setting of response to set value change in select any one of 3 steps (Slow, Medium, Fast) in PID control. In order to achieve faster controlled object response to set value change, select Fast. However, slight overshoot is unavoidable when selecting Fast. Depending on the controlled object, specify Slow if overshoot should be avoided.
PAGE 187
8. FUNCTIONS 8.2.6 Scale correction This is the function of correcting the motor speed measured value and control output when the motor speed measured value differs from the actually measured value or motor speed set value differs from the actually measured value. SR Mini HG SYSTEM Control output (Current/voltage output) Motor speed set value Motor Be different Actual measured value Be different Motor speed measured value : When scale correction was executed, it is revised.
PAGE 188
8. FUNCTIONS Example: Correction in the following value. Control output: Display scale high: Display scale low: Output scale high: Output scale low: Voltage output 0 to 10 V DC 300 mm/min 0 mm/min 400 mm/min 0 mm/min Motor speed set value: 250 mm/min Motor speed measured value: 245 mm/min Actual measured value: 240 mm/min 6.51 V DC after scale correction Voltage output 6.
PAGE 189
8. FUNCTIONS 8.2.7 Output change rate limiter The output change rate limiter limits the variation of manipulated output (MV) for a time unit. You can set an output variation, and control the output, when your object requires to avoid sudden variation. The output variation limiter is particularly effective when a sudden variation may cause the controller to crash, or when it may cause a large current. Also, it is very effective when you are dealing with current output or voltage output.
PAGE 190
8. FUNCTIONS 8.2.8 Alarm hold function In the alarm hold function, the alarm function is kept invalid even if the motor speed measured value is in the alarm range when the power is on or the operation mode is switched to RUN from STOP. The alarm function is held until it passes with H-SIO-A alarm hold cancel time. H-SIO-A alarm hold cancel time: Set the time which cancels hold action of alarm.
PAGE 191
8. FUNCTIONS 8.2.9 Assignment of channels Channel number of H-SIO-A modules uses the same kind of channel number as H-TIO- modules and H-CIO-A modules. If the H-SIO-A modules are mounted together with H-TIO- modules and H-CIO-A modules, the channel numbers are continued. Channel number is decided in order automatically from the left. Example: Examples of channel number assigning in the following system configuration. H-PCP-J module ......1 H-TIO-B module........2 H-SIO-A module .....1 H-CIO-A module ......
