Chapter 3 Functions for Reading Operation 3.1 Read Operation ................................................................... 30 3.1.1 Scanning method ................................................................... 30 3.1.2 Data-send mode .................................................................... 32 3.2 Read Modes ......................................................................... 33 3.2.1 3.2.2 3.2.3 3.2.4 Single label read mode ..................................................
Chapter 3 3.1 Functions for Reading Operation Read Operation 3.1.1 Scanning method There are two methods for triggering the BL-700 to read bar codes; the “Level signal” method and the “One-shot signal” method. The example given for these two methods uses the “single label read mode” (➮ see P.33), which reads one bar code while trigger input turns on once, and uses the “after read” as the data-send mode (➮ see P.32).
Chapter 3 Functions for Reading Operation ■ One-shot signal trigger The unit detects the rising edge of the trigger input and starts reading bar codes for the preset input time. The laser beam turns off after reaching the specified decode count and the unit sends the readout data. The remaining actions are the same as those for level signal trigger.
Chapter 3 Functions for Reading Operation 3.1.2 Data-send mode In the single label read mode only, you can select from the two data send modes (OK/NG output on trigger) described below: In the multi-label read mode, you can only select the “send after reading” mode. • Send after read The unit outputs the communication and OK/NG signals after a successful read (trigger output turns on as many times as the preset decode count). This is the same operation as in the time chart described in “3.1.
Chapter 3 3.2 Functions for Reading Operation Read Modes The BL-700 provides 4 types of read modes. 3.2.1 Single label read mode This mode allows the unit to read one bar code during one trigger input signal. The operation and timing chart are described on page 30 to 32. 3.2.2 Multi-label read mode 1 (Multi 1) This mode allows the unit to read several bar codes printed on one label as shown below during one trigger input signal. The unit outputs the readout data sequentially.
Chapter 3 Functions for Reading Operation 3.2.3 Multi-label read mode 2 (Multi 2) As with multi 1 mode, this mode allows the unit to read several bar codes continuously while the trigger input is on. (The number of bar codes that can be read depends on the buffer capacity. See P.86.) The difference between the two modes is that multi 2 mode sends all the readout data at one time after the trigger input turns off.
Chapter 3 Functions for Reading Operation 3.2.4 Multi-label read mode 3 (Multi 3) As described in multi-label read modes 1 and 2, this mode also allows the unit to read several bar codes (up to 4 codes) while the trigger input is on. The unit sends the readout data at one time according to a specified sequence after the trigger input turns off. When up to 4 codes are in the laser beam’s field, the unit can simultaneously reads all of them.
Chapter 3 Functions for Reading Operation Example Suppose that the following codes are specified: Code 1: CODE39, 10 digits Code 2: EAN/UPC, 13 digits Code 3: None Code 4: CODE39, 8 digits When the unit successfully reads all 3 types of codes: Header ABCDE12345 , 4901234567894 , KEYENCE1 Delimiter When the unit fails to read Code 1 (CODE39, 10 digits) Header ERROR , 4901234567894 , KEYENCE1 Delimiter When the unit fails to read Code 1 (CODE39, 10 digits) and Code 4 (CODE39, 8 digits) 3 Head
Chapter 3 Label Orientation Mode As shown below, this mode allows the unit to read bar codes only in the specified orientation when bar code labels are moving both in the forward and reverse orientations. Forward Reverse orientation orientation 4 9000000 * BL-700 TEST TIMING OK/NG LASER ON 4 9000000 STB 3.3 Functions for Reading Operation Normally, the unit can read bar codes regardless of the orientation.
Chapter 3 3.4 Functions for Reading Operation Test Mode Test mode can be used for the bar code reading test. Because trigger input is not required, this mode allows you to perform a reading test easily. You can select one of the following 3 methods to enter the test mode. 3.4.1 Reading rate check mode The unit scans a bar code100 times and analyzes how many times it can decode the scanned data (reading rate).
Chapter 3 Functions for Reading Operation 4. In the test mode, the unit outputs the serial communication data in the following format every 100 scans. By connecting the BL-700 to a PC and using a BL setup software terminal, the following data can be displayed on the PC screen. ➮ See P.79 for details of operation. Delimiter Readout data : m * m = 0 to 100 (zero-suppressed) * ON/NG LED turns ON but OK/NG output does not turn ON. 5. Press the TEST switch again to exit the test mode.
Chapter 3 Functions for Reading Operation Reading rate STABILITY LED OK/NG LED 100 or more 5 LEDs ON 50 to 99 4 LEDs ON Green (The readout count equals or exceeds the matching decode count.) 10 to 49 3 LEDs ON 5 to 9 2 LEDs ON 1 to 4 1 LED ON 0 – Red (The readout count is below the matching decode count.) Red The BL-700 continues to read the data while the laser beams scan the bar codes. Thus, the STABILITY LEDs are not ON. When the bar code reading stops for 0.
Chapter 3 Functions for Reading Operation 3.4.3 Online test mode When the BL-700 always reads the bar codes, the reading stability can be displayed in real time using the STABILITY LEDs. This mode is called online test mode. ■ Setting 1. To set the online test mode, send the following command from the BL setup software terminal. To use the terminal, see P.77. Command to be sent: #TEST1 Send-data: OK When OK is returned to the command sent, it indicates the mode is set.
Chapter 3 3.5 Functions for Reading Operation STABILITY LEDs STABILITY LEDs allow you to easily check reading stability and operation status. Indication of reading stability ■ When reading rate check mode is selected STABILITY LEDs light according to the reading rate shown in the table below. Although, in the test mode, the unit does not output an OK/NG signal, the OK/NG LED lights as below. (Comparison to the preset data is not performed.
Chapter 3 Functions for Reading Operation ■ Unit operation status display STABILITY LEDs indicate the following information in addition to reading stability. Operation status STABILITY LED display Action to be taken Power-on LEDs turn on sequentially from the bottom. During setup (➮ see P.92) All the LEDs flash. Waiting for setting data send/receive (➮ see P.73) The 1st, 3rd and 5th LEDs from the top flash simultaneously. In this status, send the settings from the setup software.
Chapter 3 3.6 Functions for Reading Operation Preset Function (Compare with:) 3.6.1 What is the preset function? The BL-700 can store one bar code as preset data. It compares the preset data to the bar code data actually read and outputs an OK/NG signal to whether there is a match. Using the BL-700 preset function, you can prevent the wrong products from entering the line without using a PC.
Chapter 3 Functions for Reading Operation 3.6.2 Wildcard Symbols (“!” and “?”) Using “!” and “?” in the preset data allows for flexible settings. ?: Does not define numeric values (characters) of certain digit(s) of the bar code. !: Ignores numeric values and symbols within the dot box and recognizes the bar codes as the same group.
Chapter 3 3.7 Functions for Reading Operation Additional Information When sending the bar code data, you can add the following data to the readout data. Additional information types ■ Decode match count add function Adds the number of successful scans during one bar code reading (decode count) to the end of the readout data (up to 9999 count). However, this decode count is never less than the preset decoding match count. This function can be used to check reading stability and code label quality.
Chapter 3 Functions for Reading Operation ■ Code type add function Adds the bar code type before the readout data . Delimiter : Readout data t= 0 1 2 3 4 5 6 7 8 : CODE39 : ITF : Industrial 2of5 : Codabar : EAN/UPC (A•E) : CODE 128 : COOP 2 of 5 : Read error : CODE93 t ■ Label orientation add function Adds the orientation of bar code travel before the readout data.
Chapter 3 3.8 Functions for Reading Operation Max. Code Length (Designated Digit ) Output Function This function allows you to output the designated digit(s) as desired from the readout bar code data. For example, from bar code data “49123456”, you can extract “1234” for output. Setting digits to be output Set the digits to be output as shown below. Individually set the digits for codes 1 to 4. 1. Set the direction to designate. * Set from which direction you want to start counting.

Chapter 5 5.1 Serial Communication Serial Communication The BL-700 communicates with the PC via the RS-232C serial port. This enables you to change the BL-700’s settings from your PC. Communication types The BL-700 provides the following two communication types: • Data communication Sends read bar code data from the BL-700 to the PC. • Command communication Changes the BL-700’s settings by sending a command from the PC to the BL700. * All communication is performed using ASCII codes.
Chapter 5 5.2 Serial Communication Details on Data Communication Communication protocols (Hardware handshaking) The BL-700 supports the following four handshaking protocols. ■ No Handshaking Read data LASE R ON STB OK/N G TIMING TEST BL-700 • The BL-700 sends read data to the PC without using any handshaking protocol.
Chapter 5 Serial Communication ■ ACK/NAK Handshaking The ACK/NAK handshaking uses (06H) and (15H) instead of PASS and RTRY used in the PASS/RTRY handshaking, respectively. With these protocols, the BL-700 sends back different characters, but performs the same operation. ■ RTS/CTS Handshaking • When the PC’s RTS (BL-700’s CTS) signal turns off, the BL-700 becomes ready for data transmission. When the PC’s RTS signal turns on, the BL-700 starts data transmission.
Chapter 5 Serial Communication Read Data Format Set the data format of the Header and Delimiter, respectively. Header Read data Delimiter With the setup software, the following formats can be selected. Other than the following formats, you can freely set up to 5 characters. Header: (1BH), (02H), None Delimiter: (0DH), (0DH) (0AH), (03H) Read Error Code If the BL-700 fails to read a bar code, the BL-700 sends back a read error code.
Chapter 5 5.3 Serial Communication Command Communication The BL-700 includes commands to directly operate the BL-700 (direct control commands) and the commands used to change or confirm the BL700’s settings (parameter setting commands). 5.3.1 Setup of Direct Control Commands Communication procedure Command LASE R ON STB OK/N G TIMING Response TEST BL-700 1. Send a direct control command from the PC to the BL-700. 2.
Chapter 5 Serial Communication Explanation of Direct Control Commands The following describe direct control commands in details. Read operation control This command specifies the data read timing. ● Trigger on Command: LON Response: None ● Trigger off Command: LOFF Response: None • Even when the read operation is controlled with these commands, the BL-700 performs the same operation as with the trigger input (➮ see P.30 to 36).

Chapter 6 6.1 PLC Link PLC Link The PLC link enables read data to be directly stored in the internal memory of a PLC (programmable logic controller). Since the BL-700 directly controls the PLC’s memory, no program is required for data communication, resulting in a reduced number of programming steps. As compared with the serial communication using a computer, the PLC link involves the following limitations: • The BL-700 settings cannot be changed because the PLC link cannot send a command to the BL-700.
Chapter 6 PCL Link 6.1.2 Devices used for PLC link The BL-700 supports the following PLC devices. To use MELSEC-A series, select the data register or file register. The available memory areas of the MELSEC-A or SYSMAC-C may be smaller than the following data. For details, see the instruction manual for the PLC being used.
Chapter 6 6.2 PLC Link Setting the BL-700 and PLC 6.2.1 Setting the BL-700 series Use the BL-700 setup software to set the following. For the differences in setting due to the link unit or PLC type, see the next subsection “Setting the PLC”. 1. In “Comm settings-1”, set the following data. • Match the baud rate, data length, parity and stop bits of the BL-700 to those of the PLC. • Disable the RTS/CTS protocol. • Disable the multi-drop link. 2. In “Comm settings-2”, set the following data.
Chapter 6 PCL Link Settings for KV-L2/KV mode* 1. Set the KV-L2’s communication mode to “KV mode”. Set the BL-700’s communication mode to “KV”. 2. The KV mode must be always set to the following values: • Baud rate : 9600 bps • Data length: 8 bits • Parity: Even • Stop bit length: 1 bit Set the RS-232C communication parameters of the BL-700 according to the above settings. 3. Set the station number to “00”. 4. To use the KV-L2 port 2, set the port 2 selector switch to “RS-232C” or "RS422A". 5.
Chapter 6 PLC Link Setting SYSMAC-C series 1. Set the RS-232C communication parameters (baud rate, data length, parity and stop bit length) according to the BL-700’s settings. 2. Set the unit number according to the BL-700’s setting. 3. Set the command level to “Level 1, 2, 3”. 4. Set “1:1/1:N” to “1:N”. 5. Set “I/O port” to “RS-232C”. 6. Set “Trigger input” to “Internal”. 7. Set “Supply 5 V” to “Disable”. 8. Set “CTS” to “0 V (Normally ON).
Chapter 6 6.3 PCL Link Device Assignment The data areas used to control the BL-700 are provided in the PLC’s internal memory (D areas or DM areas). When a device head address is specified on the “PLC SETUP” screen in the BL700 setup software, the device numbers are automatically assigned based on the specified head address. Data memory head address [Specified head address] +00 indicates the area where the bar code data is stored.
Chapter 6 PLC Link Data memory areas Bar code data read by the BL-700 is stored in the areas starting from “+00”. (Based on the specified data memory head address). In the following table, “A” indicates the data memory head address. Address Description Reference page Data memory flag area P.113 A+01 Label orientation P.
Chapter 6 PCL Link Detailed description of device assignment +00 to +03 Data memory head address Specify the head address of the areas where the read data is stored. (Specify the head address as binary data.) When using the BL-700 in multi-label read mode 3, +00 to +03 are used as the data memory head address for Codes 1 to 4, respectively. However, data is not stored in the area for which the code type is not set.
Chapter 6 PLC Link ● Operating procedure 1. Set the +05 address to “0”. 2. To trigger the BL-700 to start reading (to turn the trigger ON), set the +04 address to “1”. 3. When the BL-700 recognizes the change in the +04 address, it returns a “1” to the +05 address. The BL-700 then starts reading the data. 4. When a “1” is returned to the +05 address, it indicates that the BL-700 succeeded in the trigger ON function. If a “1” is not returned, the BL-700 has not recognized the +04 address yet.
Chapter 6 PCL Link ● Operating procedure 1. To trigger the BL-700 to start reading, set the +04 address to “1”. 2. When the BL-700 recognizes the +04 address, it returns a “0” to the +04 address. The BL-700 then starts reading the data. 3. The BL-700 continues reading for the “one-shot signal trigger time” set at the +06 address. 4. When the BL-700 has read all the bar codes, it writes the new data in A+05 to A+69. If a reading error occurs, the BL-700 writes a reading error code in A+05 to A+69.
Chapter 6 PLC Link • After data processing is completed, set the flag area to “2”. Writing new data is impossible until the flag area is set to “2”. • Data that cannot be stored in the specified areas is retained in the BL-700 transmission buffer. (For the capacity of the BL-700 transmission butter, see p.88.) If the amount of retained data exceeds the buffer capacity, the entire contents of the buffer is cleared and an “OVER” code is stored in the memory data area (A+05 to A+09).
Chapter 6 PCL Link Note 1: When test mode is enabled, the BL-700 does not write data. Note 2: These data areas accept up to 64 digits. However, the BL-700 can read only 32 digits. When the bar code type is CODE128 and the start character is CODE-C, up to 64 digits can be read.
Chapter 6 6.4 PLC Link PLC Link Error When a communication error occurs during PLC link, the BL-700 stops communications. In this case the bottom STABILITY LED flashes. When this error occurs with the PLC link, check the following points: 1. Check if the RS-232C communication parameters (baud rate, data length, parity and stop bit) for the PLC are matched with the N-400’s settings. 2. Check if the PLC link is set to “Use” in the communication parameters 2 setup. 3.
Chapter 6 6.5 PCL Link Communication Time ■ Time required data transmission The time required for data transmission from the BL-700 to the PLC is as follows: This communication time may change depending on the PLC's scan time and the model of the PLC. * When the RS-232C communication baud rate is 9600 bps: Number of data digits MELSEC-A SYSMAC-C KV (KV mode) 10 Approx. 220 ms Approx. 330 ms Approx. 440 ms 20 Approx. 270 ms Approx. 380 ms Approx. 680 ms 32 Approx. 320 ms Approx.

Appendices Appendix E Example Program for Serial Communication The following is a example program that allows data communication and command communication. Type in a command and press [Enter] to send the data to the BL700. Only the QUIT command can be sent by pressing [Q].
Appendices Appendix F Sample Program for the PLC Link The sample program stores the read data in D105 (DM105) and subsequent DMs. You can change the program to suit your application. Before using the sample program, check that your system meets the following requirements. ■ BL-700 settings • The scan method is “level signal trigger”. • Use the “PLC trigger area”. • The DM head address is “0000”. ■ Processing of data memory flag ... Sequential processing * This sample program uses the level signal trigger.
Appendices ■ Program for the MELSEC-A Series M9038 MOV K100 D1 MOV K2 D100 MOV K1 D4 MOV K0 D4 Specify the head address of the data memory area. (Enter “2” in the data memory flag. Use sequential processing to process the flag.) X0 X0 LD= D100 K3 Data stored in D105 and subsequent areas is processed. MOV K2 D100 Enter “X0” for the reading trigger input. When D100 becomes “3”, the specified processing is performed. After processing is completed, enter “2” in D100.
Appendices Appendix G Troubleshooting If a problem occurs during operation, please check the following troubleshooting notes first. If you cannot fix the problem, contact KEYENCE or your nearest dealer. Bar codes cannot be read. Check whether power is applied to the unit. • Confirm that the power supply voltage and capacity is 5 VDC±5% and 510 mA. Check the wiring of the power supply unit and the trigger input terminal. ➮ See P.6 to 7.
Appendices Check the bar code. A bar code with blurred sections, defects or stains may not be read correctly. Bar codes printed with dot matrix or ink jet printers are prone to such problems. Check whether the transmitter (light source) and the receiver (optical pickup) are clean. If moisture, oil or dust adheres to the transmitter or the receiver, wipe the units using a soft cloth and a mild plastic cleaner. Check the environmental conditions. ➮ See “Hints on correct use” on P. 23 to 25.
Appendices Appendix H CODE93 Specifications ■ Setting of No. of Digits • The start/stop character and check digit are not included in the number of digits. ■ Data Transmission • The start/stop characters and check digit cannot be sent. • Control codes are sent. Note: Do not use CODE93 with control codes when using a multi-drop link. Communication errors may occur. ■ Registration of Preset Data • When ! or ? is registered as preset data, it functions as the Preset “!” “?” Function, as described in P.45.
Appendices CODE128 Specifications ■ Setting No. of Digits • The start/stop character and check digit are not included in the number of digits. • FNC1 to 4 (Function codes), SHIFT, and CODE-A to -C should not be added to the number of digits. • The number of digits setting range varies depending on the start character (CODE-A to -C). CODE-A, B: 1 to 32 CODE-C: 2 to 64 One digit of CODE-A or CODE-B represents two digits of CODE-C.
Appendices Appendix J Checksum Calculation Method You can add a checksum to transmitted data. (The checksum cannot be added to a command or a response to a command.) Adding a checksum enables incorrect data translation to be detected in the RS232C communication. If the checksum does not match when the PASS/RTRY or ACK/NAK protocol is used, modify the program so that the “Request to resend” (RTRY or ) command is sent to the BL-700.
Appendices Checksum calculation method Heade ABC123 CC Delimiter Calculate the checksum (CC) in the above example. Convert each character into the ASCII code as shown below, and express the result as 8-bit binary numbers. Calculate the “Exclusive-OR” of the binary numbers of each bit.
