Product Summary
The Allen-Bradley 1784-PCIDS is a DeviceNet universal PCI scanner card for host computers. This card provides one DeviceNet terminal for network connections. It enables monitoring, configuration, explicit messaging, and I/O scan capabilities. The 1784-PCIDS installs into a PCI rev. 2.1 compliant slot. Its mechanical form factor is a PCI 5V, 32-bit short card.
Expert Technical Evaluation & Performance Review
This Rockwell Automation module operates as a reliable DeviceNet PCI card. The hardware receives power directly from the PCI bus. The host computer provides 5V @ 625 mA maximum. The DeviceNet network supplies +24VDC @ 90 mA maximum (Class 2). These power requirements ensure stable operation within standard industrial PC environments.
The module supports a 2048-byte input image table and a 2048-byte output image table. This capacity allows for substantial data exchange between the host and the DeviceNet network. The card offers built-in status indicators for I/O status, Network Status, and Module status. Engineers can quickly diagnose network health and device connectivity using these LEDs.
Series A of this card supports I/O Linx and RSNetworx for DeviceNet. Series B is compatible with RSLinx and RSNetworx for DeviceNet. This compatibility ensures integration with Rockwell Automation’s standard software suites. Users must verify their software version before deployment. The card requires only 2 MB of disk space on the host computer.
Step-by-Step User & Installation Guide
Proper handling is critical due to the card’s open enclosure. The exposed electronic circuitries require electrostatic discharge (ESD) precautions. Always touch only the corners of the card during installation. Use anti-static wrist straps when handling the module. Mount the card on a properly grounded table to prevent damage.
First, power down the host computer completely. Then, open the computer chassis to access an available PCI slot. Ensure the slot is PCI rev. 2.1 compliant. The mechanical form factor is a PCI 5V, 32-bit short card. Align the card’s edge connector with the slot and press firmly until seated. Secure the card’s bracket to the chassis.
After installation, connect the DeviceNet cable to the single terminal on the card. Apply power to the host computer. The operating temperature range is 32 to 131 degrees Fahrenheit. The storage temperature range is -40 to 185 degrees Fahrenheit. The relative humidity tolerance is 5 to 95%. Verify these environmental conditions match your industrial setting.
Finally, install the required software. For Series A cards, use I/O Linx or RSNetworx. For Series B cards, use RSLinx or RSNetworx. The software will detect the 1784-PCIDS and configure the necessary drivers. Always store the card in its anti-static bag when not in use. Never remove the card from the bag for long-term storage.
