Allen-Bradley 1784-PCIS ControlNet PCI Communication Card – Rockwell Automation ControlNet Interface Series
When a ControlNet communication link goes down on the plant floor, the consequences are immediate and severe: PLCs lose synchronization, HMI screens go blank, and entire production lines halt without warning. In time-critical manufacturing environments — automotive assembly, oil & gas processing, water treatment — even minutes of unplanned downtime translate into tens of thousands of dollars in losses. The Allen-Bradley 1784-PCIS is the hardware bridge that keeps your PC-based control workstation fully integrated into the ControlNet network, ensuring that communication never becomes the weakest link in your automation architecture.
The 1784-PCIS occupies a well-established position within Rockwell Automation’s 1784 series of PC-based communication interface cards. Designed for standard PCI bus slots, it provides a dedicated ControlNet channel that offloads network processing from the host CPU, delivering deterministic, high-speed data exchange between your workstation and ControlNet-connected controllers, I/O adapters, and drives. As ControlNet remains one of the most widely deployed deterministic industrial networks globally — with millions of installed nodes across process, discrete, and hybrid manufacturing — the 1784-PCIS continues to be a critical spare and upgrade component for system integrators and plant engineers worldwide.

- Redundant Media Support: Compatible with ControlNet redundant coaxial media configurations for high-availability applications.
- Proven Field Reliability: Part of the battle-tested 1784 series with decades of deployment in harsh industrial environments.
Industry & Equipment Applications
- Automotive Manufacturing: Body welding lines, paint shop conveyors, and assembly robots using ControlLogix or PLC-5 controllers.
- Oil & Gas: Upstream SCADA workstations, pipeline monitoring PCs, and DCS integration nodes requiring deterministic ControlNet links.
- Food & Beverage: Packaging line HMI workstations communicating with ControlNet-based I/O and drives.
- Water & Wastewater Treatment: Plant-wide SCADA PCs interfacing with distributed ControlNet I/O panels.
- Pharmaceutical: Batch control workstations in FDA-regulated environments where validated communication infrastructure must be maintained.
- Power Generation: Turbine control and substation automation systems with legacy ControlNet backbones.

Our Quality Assurance Process
At Konmask.com, every Allen-Bradley 1784-PCIS unit goes through a rigorous multi-stage inspection before shipment:
- Visual Inspection: PCB, connectors, and BNC port examined for physical damage, corrosion, or counterfeit indicators.
- Authenticity Verification: Holographic labels, date codes, and Rockwell Automation part markings cross-referenced against manufacturer records.
- Functional Test: Where applicable, cards are bench-tested for PCI bus enumeration and ControlNet node initialization.
- ESD-Safe Packaging: All units are packed in anti-static bags with foam cushioning and clearly labeled for safe transit.
- Documentation: Each shipment includes a packing list with part number, serial/lot reference, and inspection sign-off.

Frequently Asked Questions
Q: Is the 1784-PCIS compatible with Windows 10 / Windows 11?
A: The 1784-PCIS requires RSLinx Classic drivers. Rockwell Automation’s driver support for this card on Windows 10 is available in RSLinx Classic v3.90 and above. Windows 11 compatibility should be verified against your specific RSLinx version — contact us for guidance.
Q: Can the 1784-PCIS be used in a PCIe slot?
A: No. The 1784-PCIS uses the legacy 32-bit PCI bus interface and is not electrically or mechanically compatible with PCIe slots. For PCIe-based systems, consider the 1784-PCIE series or USB alternatives such as the 1784-U2CN.
Q: Does this card support ControlNet redundant media?
A: Yes. The 1784-PCIS supports ControlNet redundant coaxial media configurations when used with appropriate taps and cabling infrastructure.
Q: What is the difference between 1784-PCIS and 1784-PKTX?
A: The 1784-PKTX provides dual ControlNet channels on a single PCI card, while the 1784-PCIS provides a single channel. The PKTX is preferred when two independent ControlNet network connections are required from one workstation.
Q: Do you provide a warranty on this product?
A: Yes. All units sold through Konmask.com carry a standard warranty against defects. Please contact support@konmask.com for full warranty terms applicable to your order.
Q: Can you supply a Certificate of Conformance or test report?
A: Yes, documentation packages including inspection records and CoC can be arranged upon request for regulated industries.
