Page 14: Functioning Modes
Instruction Manual 5. FUNCTIONING MODES The DS2 light grids detect and measure objects placed inside the detection area. Hence, beam interruptions can cause output switching, analogue output signal variation and serial output updating. Small objects (up to 12 mm) detection and geometrical measurements determined with approximately 6 mm resolution can be obtained by setting the device according to the different functioning modes. -
Page 15: Transition Detection (Number Of Transitions)
Instruction Manual 5.3. Transition detection (number of transitions) The transition detection counts the number of transitions in the detection area. The number of transition increases each time that an object is detected inside the detection area and decreases each time the objects remain outside (transition light->dark). 5.4. -
Page 16: Rs485 Serial Output Setting
Instruction Manual 5.5. RS485 serial output setting Serial output data updating is usually made at the end of each scanning cycle. This conditions enormously the response time, as it is depends on the serial baud-rate, data structure and information detail that has to be transmitted on the serial output for the application. Some serial configuration commands have been added to make the device flexible to different applications. -

Instruction Manual 6.2. Remote programming The function programming and selection is made using an user interface on a remote host, which communicates with DS2 using the standard RS232 serial interface. The interface can be found in the CD supplied with the device packet. The remote programming function selection is activated only by dip-switches (dip-switch 1Aoff) N.B.: DS2 device fix in memory the last setting configuration from remote user interface. -

Page 33: Areascan
Instruction Manual DS2 SERIES – COMMUNICATION PROTOCOL 7. AREAscan 7.1. Packet description As mentioned, the communication protocol requires a master unit and a slave unit. The communication type is half duplex (RS485). The exchange of information is made in the request-reply mode: the master sends a data packet to the slave that replies sending another data packet to the master. -
Page 34: Operating Mode: Ds2 (Master) Host Interface (Slave)
Instruction Manual 7.2 Operating mode: DS2 (master) Host Interface (slave) At powering the DS2 becomes the master and transmits periodically, as previously explained, a packet at each scanning of the measurement information according to the configuration. The host, which is the slave, receives the packet and elaborates the data. This is the only case where a response packet is not necessary. - Page 35 Instruction Manual b. Complete ASCII scanning result (Complete beam status array) - 0x41 (‘A’ ASCII) Sends to host the pattern with the ASCII information relative to each beam. DS2 sends: aaaaaa bbbbbb cccccc ….. zzzzzz ss 0x2A 0x41 0x0D where: aaaaaa = 6 ASCII codes (3 bytes) with information concerning the 01-21 photoelements bbbbbb = 6 ASCII codes (3 bytes) with information concerning the 22-42 photoelements cccccc = 6 ASCII codes (3 bytes) with information concerning the 42-63 photoelements...

Page 37: Configuration Mode: Ds2 (Slave) Host (Master)
Instruction Manual 7.3. Configuration mode: DS2 (slave) Host (master) 7.3.1 Host appropriation procedure of the bus To access the configuration mode, the DS2 has to receive a special command that momentary suspends scanning and the control is passed to the host. The host thus becomes the master and the DS2 the slave. -
Page 38: Command Packet Description
Instruction Manual 7.3.2 Command packet description: a. Synchronism command - 0x43 (‘C’ ASCII) The host can use this command when connected to DS2 to obtain the local/remote configuration parameters. If the serial transmission speed is missing, all known baud-rates can be tested until the connection is established. - Page 39 Instruction Manual b. Scanning suspension command - 0x44 (‘D’ ASCII) Momentary suspends the scanning and passes the control to the host. Host sends: 0x02 0x01 0x44 0x03 0xBA DS2 responds: 0x02 0x01 0x03 0x9A 0x64 The following figure is similar to the previous one with the difference that the scanning now does not re-start automatically after receiving the command (see point 9).
- Page 40 Instruction Manual d. Scanning command on request (Data sending on request ) - 0x46 (ASCII ‘F’ ) When DS2 is programmed in Remote Mode – Data Sending On Request, the host sends this special command to request the information packet relative to each single beam or partial scanning information in the form of one or two numeric measurements of the following type: - Top Beam (dark or light) - Bottom Beam (dark or light)
- Page 41 Instruction Manual Remote configuration writing - 0x48 (‘H’ ASCII) Saves in the DS2 non-volatile memory the binary information of the remote configuration. Host sends: 0x02 0x08 0x48 rrrrrrr 0x03 DS2 replies: 0x02 0x01 0x03 0x96 0x68 where: rrrrrrr = 7 bytes with the remote configuration status (see Synchronism packet) = checksum (complement to one of the Length, Type and Data field bytes sum) g.
