Note before operating keys

• Pressing the key for approx. 1 second from any mode turns the control output OFF.• Once the control output OFF function is enabled, the function cannot be released

even if the power to the instrument is turned OFF and ON again.To cancel the function, press the key again for approx. 1 second.

• Pressing the key registers the set value and proceeds to the next setting item.If the key is pressed for approx. 3 seconds from any mode, the unit reverts to thePV/SV display mode.

Turn the Power ON

The PV display indicates the input type, and the SV display indicates input range highlimit value selected during Input type selection for approx. 2 seconds after the power isturned on. See (Table 6.1-1) below.During this time, all outputs and LED indicators are in OFF status.Control will then start indicating the PV (process variable) on the PV display and SV(desired value) on the SV display.

[ ] Set value lock• Locks the set value to prevent setting errors.The setting item to be locked differs depending on the selection.• When selecting Lock, set the necessary items in the status Unlock,then select Lock 1, Lock 2 or Lock 3.• Fuzzy self-tuning PID or Auto-tuning (AT) will not function if Lock 1 or Lock 2is selected.[About Lock 3]When using the unit as a Fixed value controllerThe set values of the selected Set value memory number can be changedtemporarily. However, if the memory number is changed, the changed valuesof the previous number are cancelled. (Returns to the values before setting.)When using the unit as a Program controllerThe set values of the currently performing step number can temporarily bechanged. However, if the step number is changed, the changed set values arecancelled. (Returns to the values before setting.)Set value change during running standby status will be invalidated.(Running starts at the values memorized in the memory.)

• Be sure to select Lock 3 when changing the set value frequently viacommunication function considering the life of non-volatile memory.

• Selection item:(Unlock): All set values can be changed.(Lock 1): None of the set values can be changed.(Lock 2): Only SV can be changed.(Lock 3): All set values can be changed temporarily. However, changedvalues revert to their previous value after the power is turned off becausethey are not saved in the non-volatile memory.This function is suitable when changing value temporarily.Since this function has no relation to the memory life, it is well suited whenchanging set values frequently using Shinko programmable controller(PC-900, PCD-33A with SVTC option).Do not change any setting item in Auxiliary function setting mode 2. If anyitem in the mode is changed, it will affect other setting items such as theSV and Alarm value.

10. Control actions10.1 Fuzzy self-tuning

Fuzzy self-tuning is a function to perform a fine adjustment of PID values automatically.The stable control can be carried out even if the conditions of the production process arechanged due to things like variation and variability.

If Lock 1 or Lock 2 is selected, Fuzzy self-tuning or Auto-tuning does not work.In the control system in which load fluctuation periodically occurs, the Fuzzyself-tuning may malfunction.In such cases, use the controller with the PID auto-tuning mode.

(1) When the control initiates, the unit performs this function by the PID valuespreviously adjusted.

(2) When the control result is disordered by disturbance or a change in theprocess, the controller checks the converging status, and performs a fineadjustment of PID values if necessary.

(a) If the convergence is performed smoothly, the PID values are not changed.(b) If the convergent speed is slow, the controller corrects the PID values

to accelerate the convergence.(c) When overshoot is generated during the convergence, the controller changes

the PID values to correct this.(d) When hunting occurs, the controller checks its waveform and performs a

fine adjustment of PID values.

The instrument is always in self-tuning status, and when deviation occurs, the tuningstarts. Even in Fuzzy self-tuning status, when very large hunting occurs and thecontrol is not stabilized, auto-tuning starts automatically.When the auto-tuning “Perform” is selected by the keypad, auto-tuning initiates.When the control is stabilized, the auto-tuning is released and the controllerreturns to self-tuning status.

The controller can be used without Fuzzy self-tuning by selecting the internal switch.When using the controller without Fuzzy self-tuning, perform the PID auto-tuning orset the proper PID values by key operation.

10.2 Explanations of PID

(1) Proportional band (P)

Proportional action is the action which the control output varies in proportion to thedeviation between the SV (desired value) and the PV (process variable).If the proportional band is narrowed, even if the output changes by a slight variationof the PV (process variable), better control results can be obtained as the offsetdecreases.However, if the proportional band is narrowed too much, even slight disturbancesmay cause variation in the PV (process variable), control action changes to ON/OFFaction and the so-called hunting phenomenon occurs.Therefore, when the PV (process variable) comes to the balanced position nearthe SV and a constant temperature is maintained, the most suitable value isselected by gradually narrowing the proportional band while observing the controlresults.

(2) Integral time (I)

Integral action is used to eliminate offset. When the integral time is shortened, thereturning speed to the setting point is accelerated. However, the cycle of oscillationis also accelerated and the control becomes unstable.

(3) Derivative time (D)

Derivative action is used to restore the change in the PV (process variable) accordingto the rate of change. It reduces the amplitude of overshoot and undershoot width.If derivative time is shortened, restoring value becomes small, and if derivative time isextended, an excessive returning phenomenon may occur and the control system mayoscillate.

10.3 PID auto-tuning of this controllerIn order to set each value of P, I, D and ARW automatically, the auto-tuning processshould be made to fluctuate to obtain an optimal value.Sometimes the auto-tuning process will not fluctuate if auto-tuning is performedat or near room temperature. Therefore auto-tuning might not finish normally.

(A) In the case of large difference between the SV and PV (process variable)as the temperature is rising.The AT process will fluctuate at a temperature of 1.5% input span lower than the SV.

(2) PID constantcalculated

(3) Controlled by thePID constant setby auto-tuning.

(4) 1.5% of input span

(Fig. 10.3-1)

(B) When the control is stable or when control temperature is within 1.5% of inputspan of the SVThe AT process will fluctuate around the SV.




(Fig. 10.3-2)

(C) In the case of a large difference between the SV and PV (process variable)as the temperature is fallingThe AT process will fluctuate at a temperature of 1.5% input span higher than the SV.

However,the control will perform to [Scaling low limit value -1% of scaling span].

(2) Self-diagnosis

The CPU is monitored by a watchdog timer, and when an abnormal status is found onthe CPU, the controller is switched to warm-up status.

(3) Automatic cold junction temperature compensation (Thermocouple input type)This detects the temperature at the connecting terminal between thermocouple andthe instrument, and always keeps it at the same status as if the reference junctionis located at 0 (32 ).

(4) Warm-up indication

For approximately 2 seconds after the power supply to the instrument is turned on, theinput type and the temperature unit are indicated on the PV display, and the input rangehigh limit value (for DC input, scaling high limit value) on the SV display.

(5) SV (desired value) ramp function

When the SV is adjusted, it approaches the new SV by the preset rate of change.When the power is turned on, the control starts from the PV (process variable)and approaches the SV by the rate of change.

(Fig. 2-3)

Shielded wire Connect only one side of the shielded wire to the FG or GND terminal so that current cannot flow to the shielded wire. (If both sides of the shielded wire are connected to the FG or GND terminal, the circuit will be closed between the shielded wire and the ground. As a result, current will run through the shielded wire and this may cause noise.) Be sure to ground FG and GND terminals. Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted pair cable.)

Terminator (Terminal resistor) The terminator prevents signal reflection and disturbance. Connect a terminator at the end of the communication cable. The IF-400 (sold separately) is available as a communication converter.

3. Communication parameters setting Set Communication parameters as follows. (Refer to the Instruction manual.)

(1) Instrument number setting Set an instrument number to each of the FC series individually when communicating by connecting plural units. (Default: 0)

(2) Communication speed selection Select a communication speed for the FC series according to that of the host computer. (Default: 9600bps)

(3) Communication protocol selection (For the FCD-13A, FCR-13A, FCR-23A, FCS-23A) Select a communication protocol. (Default: Shinko protocol)

4. Communication procedure Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the FC series (hereafter Slave).

• Response with data When the master sends the reading command, the slave responds with the corresponding set value or current status. • Acknowledgement When the master sends the setting command, the slave responds by sending the acknowledgement after the processing is terminated. • Negative acknowledgement When the master sends a non-existent command or value out of the setting range, the slave returns a negative acknowledgement as a response. • No response

The slave will not respond to the master in the following cases: • Global address (Shinko protocol) is set. • Communication error (framing error, parity error) (Fig.4-1) • Checksum error (Shinko protocol), LRC discrepancy (Modbus)

Communication timing between master and slave Master side (Notice on programming)

Set the program so that the master can disconnect the transmitter from the communication line within a 1 character transmission period after sending the command in preparation for reception of the response from the slave. To avoid the collision of transmissions between the master and the slave, send the next command after carefully checking that the master received the response.

Slave side When the slave starts transmission through the RS-485 communication line, the slave is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the response to ensure the synchronization on the receiving side. The slave is arranged so as to disconnect the transmitter from the communication line within a 1 character transmission period after sending the response.

5. Shinko protocol

5.1 Transmission mode Shinko protocol is composed of ASCII codes. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Data format Start bit: 1 bit Data bit: 7 bits Parity : Even Stop bit: 1 bit Error detection: Checksum

5.2 Command configuration All commands are composed of ASCII. The data (set value, decimal number) is represented by hexadecimal figures, and ASCII codes are used for the command. The negative numbers are represented by 2's complement.

Header : Control code to represent the beginning of the command or the response. ASCII codes are used. Setting command, Reading command : STX (02H) fixed Response with data, Acknowledgement : ACK (06H) fixed Negative acknowledgement : NAK (15H) fixed

Address (Instrument number): Numbers by which the master discerns each slave. Instrument number 0 to 94 and Global address 95. ASCII codes (20H to 7FH) are used by adding 20H to instrument numbers 0 to 95 (00H to 5FH). 95 (7FH) is called Global address, which is used when the same command is sent to all the slaves connected. However, a response is not returned.

Memory number: Set value memory number (1 to 7) Zero (0) is set to the data item which has no relation to the Set value memory. The numbers (20H to 27H) are used by adding 20H of bias.

Command type : Code to discern Setting command (50H) and Reading command (20H) Data item : Data classification of the command object Composed of hexadecimal 4 digits (Refer to the Communication command table.) Data : The contents of data (set value) differ depending on the setting command. Composed of hexadecimal 4 digits (Refer to the Communication command table.) Checksum : 2-character data to detect communication errors (Refer to 5.3 Checksum calculation.) Delimiter : Control code to represent the end of command 03H fixed Error code : Represents an error type. Composed of hexadecimal 1 digit. 0 (30H)---- Unknown error 1 (31H)-----Non-existent command

2 (32H)-----Not used 3 (33H)-----Set value out of the setting range 4 (34H)-----Unsettable status (e.g. AT is performing) 5 (35H)-----During setting mode by keypad operation

5.3 Checksum calculation Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that the communication errors can be checked. The ASCII code (hexadecimal) corresponding to the characters which range from the address to that before the checksum is converted to binary notation, and the total value is calculated. The lower 2-digits of the total value are converted to 2’s complements and then to hexadecimal figures, that is, ASCII code for the checksum.

6. Modbus protocol (Not available for FCR-15A, FCD-15A) 6.1 Modbus message framing

Modbus protocol has 2 transmission modes (ASCII and RTU), and all commands are made up of ASCII codes since the FC series (slave) runs on the ASCII mode. Data (set value, decimal number) is converted to hexadecimal figures, and ASCII codes are used. Negative numbers are represented by 2's complement. In ASCII mode, messages start with a colon (: 3AH) character, and end with a carriage return-line feed (CRLF) pair (0DH and 0AH). Intervals of up to one second can elapse between characters within the message. If a greater interval occurs, the receiving device assumes an error has occurred. A typical message frame of the slave is shown in (Table 6.1-1). (Table 6.1-1)

Header ( : ) Slave address Function code

Address Data Number of data

or data Error check (LRC) Delimiter (CR•LF)

6.2 Slave address

Slave addresses are represented by two ASCII characters. Slave address (instrument number): 0 to 95 (00H to 5FH) Slave address (instrument number) is set to the FC series in the range of 0 to 95 (00H to 5FH) beforehand by the key operation. A master addresses a slave by placing the slave address in the address field of the message. When the slave sends its response, it places its own slave address in this address field of the response to let the master know which slave is responding. Address 0 slave receives a message and returns the response message ignoring the broadcast address [0 (00H)] since slaves are not supported by the broadcast address.

6.3 Function code Function code is represented by two ASCII characters. When the message is transmitted from the master to the slaves, function code field tells the slave what kind of action to perform.

Function code Contents 03 (03H) Reading the set value and information from slaves

(Only one piece of data can be read.) 06 (06H) Setting to slaves (Only one piece of data can be written.)

When the slave responds to the master, function code field is used to indicate if it is a normal response or if an error has occurred. For a normal response, the slave simply echoes the original function code. For an exception response, the slave returns the value by adding 1 to the most significant bit of the original function code. This tells the master what kind of error occurred by adding the exception code to the response.

Exception code Contents 0 (00H) Reserve (Normal or undefined) 1 (01H) Illegal function (Non-existent function) 2 (02H) Illegal data address (Non-existent data address) 3 (03H) Illegal data value (Set value out of the range)

6.4 Data field

Data field consists of the address and number of data, and is represented by four ASCII characters. A request message from the master is composed of address, number of data or data. A response message from the slave is composed of number of bytes, data and exception code in negative acknowledgement. Effective range of data is –32768 to 32767 (8000H to 7FFFH).

ACSE Sp.

z o.o.

6.5 Error check field After calculating LRC (Longitudinal Redundancy Check) from the slave address to the end of data, the calculated 8-bit data is converted to two ASCII characters and are appended to the end of the message. [Error checking methods] The LRC is applied to the entire message. Both the character check and message frame check are calculated in the master device, and applied to the message contents before transmission. (The slave device checks each character and the entire message frame during reception.) The master is configured by the user to wait for a predetermined timeout interval before aborting the transaction. This interval is set to be long enough for any slave to respond normally. If the slave detects a transmission error, the message will not be valid. The slave will not construct a response to the master. Thus the timeout will expire and allow the master’s program to handle the error. The message addressed to a nonexistent slave device will also cause a timeout. [LRC checking] The LRC field checks the contents of the message, excluding the beginning colon and ending CR•LF pair. It is applied regardless of any parity check method used for the individual characters of the message. The LRC field is one byte, containing an eight-bit binary value. The LRC value is calculated by the transmitting device, which appends the LRC to the message. The receiving device calculates an LRC during reception of the message, and compares the calculated value to the actual value it received in the LRC field. If the two values are not equal, an error message is returned. How to calculate LRC The LRC is calculated by adding together successive eight-bit bytes of the message (excluding the beginning colon and ending CR•LF), discarding any carries, and then is calculated by two’s compliment of the result.

Note on setting, reading command • The data (set value, decimal) is converted to hexadecimal figures. A negative number is represented

by 2's complement. • When connecting plural slaves, the address (instrument number) must not be duplicated. • For Step (1 to 7) time (0036H, 0062H to 0068H for Modbus), and Remaining time during program control

(0084H, 009DH for Modbus), time is converted to minutes, then to hexadecimal figures, and ASCII is used. (e.g.) 1 hour 30 minutes 90minutes 005AH (hexadecimal)

• Setting range of each item is the same as that of keypad operation. • When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used. • If the alarm type is changed during Alarm 3 type selection (0023H, 007DH for Modbus) and Alarm 4 type

selection (0024H, 007EH for Modbus), the alarm value will revert to “0”. Also alarm output status will be initialized.

• It is possible to set the set value with the setting command of the communication function even when the set value is locked.

• Although the options are not applied, setting the items for the options is possible using the setting command. However, they will not function.

• Instrument numbers, communication speed and protocol of the slave cannot be set by communication function. • When sending a command by Global address (Shinko protocol) or Broadcast address (Modbus protocol),

the same command is sent to all the slaves connected. However, the response is not returned. • The memory can store up to 1,000,000 (one million) entries.

If the number of settings exceeds the limit, the data will not be saved. So frequent transmission via communication is not recommended.

Reading command • When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point

is used for a response.

Negative acknowledgement The slave will return Error code 1 (31H) (Shinko protocol) or Exception code 1 (01H) (Modbus protocol) in the following cases.

• When AT Perform/Cancel (0003H, 006AH for Modbus protocol) is selected during PI action or ON/OFF action. The slave will return Error code 4 (34H) (Shinko protocol) or Exception code 17 (11H) (Modbus protocol) in the following cases.

• If “Cancel (0000H)” of AT Perform/Cancel (0003H, 006AH for Modbus protocol) is selected while Auto- tuning is being cancelled.

Notes on programming monitoring software How to speed up the scan time

When monitoring plural units of FC series, set the program so that requisite minimum pieces of data such as PV (0080H, 0099H for Modbus protocol), OUT1 MV (0081H, 009AH for Modbus), Status flag (0085H, 009EH for Modbus), etc. can be read, and for other data, set the program so that they can be read only when their set value has changed. This will speed up the scan time.

Note when sending all set values at one time • If alarm type is changed during Alarm 3 type selection (0023H, 007DH for Modbus) or Alarm 4 type

selection (0024H, 007EH for Modbus), the alarm value will revert to “0”. First, send the selected alarm type, then send the alarm value.

8. Troubleshooting If any malfunctions occur, refer to the following items after checking the power supply of the host computer and the FC series.

Problem: Communication failure Check the following

The connection or wiring of communication is not secure. A burnout or imperfect contact on the communication cable and the connector Communication speed of the FC series does not coincide with that of the host computer. The data bit, parity and stop bit of the host computer do not accord with those of the FC series. The instrument number (address) of the FC series does not coincide with that of the command. The instrument numbers (addresses) are duplicated in multiple FC series. When communicating by RS-485 (C5 option), make sure that the program is appropriate for the transmission timing. For the C5 option, when communicating with the host computer using RS-485 board (or customers’own board) instead of Shinko IF-400, communications sometimes cannot be carried out successfully. In this case, connect 2 resistors of 680 (1/4W) as shown on the right.

Problem: Although communication is occurring, the response is 'NAK'.

Check the following Check whether or not a non-existent command code has been sent. The setting command data exceeds the setting range of the FC series.The controller cannot be set when functions such as AT are performing.The operation mode is under the front keypad operation setting mode.
