3 1. Introduction This document explains how to communicate with the PB-RS232 geteway using the PROFIBUS-DP. Below that is example code that demonstrates how to implement PROFIBUS-DP communications to the board. 2.Specifications 2.1 General specification Operating temperature range 0 C C Storage temperature -20 C C EMC susceptibility IEC 801-2, IEC 801-4, IEC Communication interface RS485(Profibus), RS232 (A Y cable is required)* Communication protocol Profibus DP Data transfer rate Maximum communication line length (wire diameter >0,34 mm² - Type A) 9600bps up to 12Mbps ,6-93,75 kbit/s ,5 kbit/s kbit/s kbit/s kbit/s Profibus addressing Via serial communication port Allowed addresses range Protection class IP40 Power supply voltage 24V DC Allowed tolerance ±15% Max. ripple ±15% Protection against reverse supply Yes connection Power supply current 24V (without motor) Power consumption Max 1.5W (without motor) *A Y cable is required to connect the motor to a RS-232 port on a PC. This cable is required when downloading CM and Profibus parameters.

LED status indicators 3.1 LED indication Indication Red Yellow Green Contents off, when Profibus communication is running OK and lights, when an error in communication accurs LED flashing - Rx/Tx data activity (LED flashing) lights, when power supply is connected CMPB 3. Connectors pin layout 3.1 Profibus communication connector Pin No. Description Function 1 NC Not connect 2 NC Not connect 3 B RS485 - B Plus to send/receive data 4 RTS Request to send 5 GND Ground for terminating resistor 6 SP Supply voltage for terminating resistor 7 NC Not connect 8 A RS485 signal A Minus to send/receive data 9 NC Not connect The bus can be connected using the following standard connectors, amongst others in accordance with PROFIBUS-DP Standard and shielded twisted pair cable: ZB4-209-DS3 6ES BA00-0XA0 6ES BB00-0XA0 Moeller Siemens Siemens Transmission speed end maximum wiring lenght Baud rate(kbps) 9.6, 19.2, Wiring length(m) Terminators It is necessary to attach bus terminator resistance to the units located at the ends of transmission line.

6 4. Profibus communication MASTER configuration SLAVE configuration Assigning and changing Profibus address To assigning or changing Profibus slave number on the Profibus interface, you need to connect the motor to a PC via the Y cable. You can use Hyper terminal which usually is included with your Windows installation disk or any other suitable software. First, you have to send **PB_CONFIG command to set Profibus Interface into configuration mode. The commands for Profibus interface are: **PB_ADDRESS=n n - slave number (000,001 up to 127) **PB_ADDRESS=? **PB_RESET **PB_FW_VERSION **PB_BOOTLOAD **PB_EXIT **PB_DEFAULTS **PB_BAUDRATE=n n- 0=38400 (default), 1=9600, 2=19200, 3=57600

7 4.2 Profibus MASTER output area Command area This is an area of 32 contiguous output bytes. These bytes are sent from the master PLC to the PB-RS232 board via Profibus DP. The last two bytes are used for synchronization. DP-Master OUTPUT area has the following structure (32Byte): Byte Description 0 WriteDataByte0 Data byte 1 WriteDataByte1 Data byte 2 WriteDataByte2 Data byte 3 WriteDataByte3 Data byte 4 WriteDataByte4 Data byte 5 WriteDataByte5 Data byte 6 WriteDataByte6 Data byte 7 WriteDataByte7 Data byte 8 WriteDataByte8 Data byte 9 WriteDataByte9 Data byte 10 WriteDataByte10 Data byte 11 WriteDataByte11 Data byte 12 WriteDataByte12 Data byte 13 WriteDataByte13 Data byte 14 WriteDataByte14 Data byte 15 WriteDataByte15 Data byte 16 WriteDataByte16 Data byte 17 WriteDataByte17 Data byte 18 WriteDataByte18 Data byte 19 WriteDataByte19 Data byte 20 WriteDataByte20 Data byte 21 WriteDataByte21 Data byte 22 WriteDataByte22 Data byte 23 WriteDataByte23 Data byte 24 WriteDataByte24 Data byte 25 WriteDataByte25 Data byte 26 WriteDataByte26 Data byte 27 WriteDataByte27 Data byte 28 WriteDataByte28 Data byte 29 WriteDataByte29 Data byte 30 WriteRequest Synchronization byte 31 ReadAcknowledge Synchronization byte

8 4.3 Profibus MASTER input area Response area This is an area of 32 contiguous input bytes. These bytes are sent from the PB-RS232 board to master PLC via Profibus DP. The last two bytes are used for synchronization. DP-Master INPUT area has the following structure (32Byte): Byte Description 0 ReadDataByte0 Data byte 1 ReadDataByte1 Data byte 2 ReadDataByte2 Data byte 3 ReadDataByte3 Data byte 4 ReadDataByte4 Data byte 5 ReadDataByte5 Data byte 6 ReadDataByte6 Data byte 7 ReadDataByte7 Data byte 8 ReadDataByte8 Data byte 9 ReadDataByte9 Data byte 10 ReadDataByte10 Data byte 11 ReadDataByte11 Data byte 12 ReadDataByte12 Data byte 13 ReadDataByte13 Data byte 14 ReadDataByte14 Data byte 15 ReadDataByte15 Data byte 16 ReadDataByte16 Data byte 17 ReadDataByte17 Data byte 18 ReadDataByte18 Data byte 19 ReadDataByte19 Data byte 20 ReadDataByte20 Data byte 21 ReadDataByte21 Data byte 22 ReadDataByte22 Data byte 23 ReadDataByte23 Data byte 24 ReadDataByte24 Data byte 25 ReadDataByte25 Data byte 26 ReadDataByte26 Data byte 27 ReadDataByte27 Data byte 28 ReadDataByte28 Data byte 29 ReadDataByte29 Data byte 30 ReadRequest Synchronization byte 31 WriteAcknowledge Synchronization byte
