Working Principle
PCI bus interface communicates with host industrial PC memory space to read/write process data buffers. On-board netX ASIC executes DeviceNet master communication stack logic, manages bus timing, cyclic input/output data polling, and acyclic parameter message exchange with all connected slave nodes. Isolated transceiver circuit electrically separates PC internal logic from field wiring to suppress transient voltage surges originating from factory field devices. On-board diagnostic logic continuously monitors bus voltage, node response timing, and signal integrity to report network faults to host PC via register status flags.
Advantage Highlights
- Dedicated hardware ASIC offloads all fieldbus processing from host PC CPU, eliminating communication latency
- Galvanic 2500 V isolation protects industrial PC motherboard from field wiring surge damage
- Single card full DeviceNet master functionality without external network adapter hardware
- Multi-OS driver compatibility for industrial PC, machine vision, and data acquisition host systems
- Compact half-length PCI form factor compatible with short-depth industrial rack PC chassis
Applicable Industries
Automotive assembly line control, material handling AGV systems, packaging machine industrial PC control, robotic cell data logging, factory floor MES data collection, metalworking machine tool peripheral communication
Installation Requirements
- Insert card into empty 32-bit PCI expansion slot inside industrial rack PC chassis; secure metal bracket with mounting screw
- Connect DeviceNet trunk cable to 5-pin terminal block following standard DeviceNet pin assignment (V+, V-, CAN_H, CAN_L, Shield)
- Install 121 Ω line termination resistor at both physical endpoints of DeviceNet trunk cable
- Earth connect cable shield at single cabinet grounding point only to avoid ground loop currents
- Install official Hilscher cifX driver software on host operating system prior to network configuration
Usage Precautions
- Do not mix DeviceNet bus cable lengths exceeding maximum topology limits for selected baud rate
- Power down industrial PC fully before inserting/removing PCI interface card
- Verify fieldbus wiring polarity before activating bus communication to prevent transceiver circuit burnout
- Do not install card in PC chassis without proper airflow cooling exceeding +60 °C ambient temperature
- Perform monthly network scan diagnostics to identify degraded slave node communication performance
