Connector: 9 pin metal shell D-SUB connector with gold plated pins. Passive components: Bus termination resistor, high grade capacitors and resistors.
Structural Features: Standard full height PCI Express add-on card layout. Metal mounting bracket fixed at card edge, with D-SUB PROFIBUS connector. Internal circuit divided into PCIe host interface region, protocol processing region and PROFIBUS transceiver region. On-board DIP switch to configure bus termination resistor enable or disable. Metal shielding bracket to reduce electromagnetic radiation. Gold plated PCIe edge connector for inserting into industrial PC PCIe slot.
Working Principle: After inserting PB3-PCIE-2 into industrial PC PCIe slot, card receives power supply from PCIe bus. Host operating system loads dedicated driver software. On-board protocol controller works as PROFIBUS DP master, sends cyclic data request to all configured slave stations on PROFIBUS bus. PROFIBUS transceiver converts differential bus signal to digital signal for protocol chip. Process data received from slaves is transmitted through PCIe bus to host PC memory. Host application software reads process data and sends output command back to card. Card transmits output data to corresponding PROFIBUS slave device. Card continuously monitors bus communication quality and records bus fault information.
Installation Requirements: Power off industrial PC before inserting PB3-PCIE-2 card. Remove PC chassis rear slot cover, insert card into empty PCIe slot and fasten metal bracket screw. Connect PROFIBUS shielded twisted pair cable to 9 pin D-SUB connector. Install Woodhead card driver software on host Windows operating system. Configure PROFIBUS baud rate, slave station address and process data mapping in configuration tool. Set bus termination resistor switch according to PROFIBUS network topology. Connect PC chassis protective earth ground reliably. Separate PROFIBUS fieldbus cable from high power motor cables.
Usage Notes: Backup configuration project before modifying PROFIBUS network parameters. Use PROFIBUS certified shielded twisted pair cable for field wiring. Set termination resistor only at two physical ends of PROFIBUS bus. Wear anti-static wristband during card installation and removal. Regularly inspect D-SUB connector tightness and LED indicator status. Do not operate card outside rated temperature and humidity range. Prevent dust accumulation on PCIe edge connector and D-SUB port.
