They are used together and they have the following significance: when a jumper is in the J1 position (see Figure above) pin 40 is connected to pin 27 (EXT TRIG+); a jumper in J2 position connects pin 20 to pin 28 (EXT TRIG-). If the jumpers are removed pin 20 and pin 40 are disconnected.

The valid address range is from 000 to 126. If an invalid value is detected, the C-BOX cannot communicate with the Profibus network. The Node Address can also be assigned through WinHost. Refer to Help on-Line. Figure 11 - Rotary Switches 2.5.2 Profibus Connector (9-Pin Female External Connector) To connect C-BOX 3X0 as a Profibus DP Slave, use a standard Siemens Profibus cable with a 9-pin male connector (see DIN 19245 part 1) and plug it into the 9-pin female external connector. 5 1 9 6 Casella di testo: HUNDREDS Casella di testo: TENS Casella di testo: UNITS 9-pin external female connector pinout Pin Name Function 1 N.C. not connected 2 N.C. not connected 3 B-LINE (RS485+) 4 RTS Ready To Send 5 GND RS485 Bus Reference 6 + 5V (galvanically isolated) RS485 Bus Power Supply 7 N.C. not connected 8 A-Line (RS485-) 9 N.C. not connected 2.5.3 Connection to a Profibus Network The following figure shows a Profibus layout with C-BOX 3X0 devices connected to a Profibus Master: Profibus DP Slave node #1 PROFIBUS DP Master Profibus DP Slave node #2 Profibus DP Slave node #n C-BOX 3X0 Figure 12 - Profibus Connection It is recommended to use only commercially available PROFIBUS connectors for connecting to the bus. Use connectors from ERNI and Siemens. If the C-BOX is installed at the beginning or end of the PROFIBUS cable segment, it is recommended to use PROFIBUS connectors, which contain an integrated terminating resistor. To ensure that the C-BOX functions without errors, the shield of the PROFIBUS cable must be grounded. – Ensure that the PROFIBUS connector uses the pin assignments shown in par 2.5.2 – Attach the PROFIBUS connector to the PROFIBUS interface socket on the C-BOX 3X0 and secure the connector with the retaining screws. – For C-Box 310 models, it is advised to use up to two ferrites (type Stewart 28A2029-0A0) on the Profibus cable to reduce electrical noise. 2.5.4 C-BOX 3X0 Configuration for Profibus DP Slave Node In order to setup the C-BOX 3X0, you need to install the function blocks in your PLC programming software and configure it. The procedure below can be generally applied for this purpose: 1. Start the PROFIBUS configurator on the DP Master. 2. Insert the CD with the device database files (.GSD) into the drive of the programming device (usually a PC). 3. Load the .GSD file HMS_1810.GSD in the configurator. 4. Configure the C-BOX 3X0 (through WinHost) setting the parameters according to the PROFIBUS network application as described in the configurator's Help On-Line or User's Manual. Further information on PROFIBUS protocol and Flow control is provided in the C-BOX 300/310 PROFIBUS document and Help On- Line installed from the configuration CD provided in the C-BOX package. NOTE 2.6 CONFIGURATION SWITCH AND 9-PIN INTERNAL CONNECTOR The 9-pin internal connector may have two different functions according to the position of the configuration switch. Figure 13 - Configuration Switch and 9-pin Male Connector POSITION MODE Normal Operation (default): In this position, the C-BOX 3X0 is in the normal operating mode. It communicates with the scanner through the 9-pin internal connector and the scanner auxiliary serial interface. The internal connector pinout is illustrated in the following table: 9-pin C-Box 3x0 connector pinout in Normal mode Pin Name 1 NC 2 RXA 3 TXA 4 NC 6 NC 9 NC DS2100A DS2400A DS4600A Matrix-2000™ Matrix-1000™ 5 SGND SGND GND GND 7 CTSA SGND AUX GND GND 8 RTSA GND NC NC POSITION MODE CFG: When the switch is in this position, the C-BOX 3X0 is in configuration mode. The communication with the scanner is interrupted and pins 2 and 3 are no longer dedicated to the scanner auxiliary interface but to the C-BOX 3X0 configuration (see table below). The system enters configuration mode and waits to be configured through WinHost (see WinHost Help On Line). The C-BOX 310 display visualizes an appropriate message. Once the C-BOX 3X0 configuration is completed, it is necessary to replace the switch in the Normal Operation position. At the end of the reboot phase, the C-BOX 3X0 is ready to function with the new configuration. 9-pin C-Box 3x0 connector pinout in Configuration mode Pin Name Function 2 RX C-BOX 3X0 Configuration 3 TX C-BOX 3X0 Configuration 5 SGND Signal Ground When the C-BOX 3X0 configuration is completed, remember to replace the Configuration switch in th...
