Allen-Bradley 1784-PKTX: High-Performance Data Highway Plus PCI Interface Solution

The Allen-Bradley 1784-PKTX Data Highway Plus (DH+) PCI Network Interface Card delivers robust, industrial-grade connectivity for integrating legacy Rockwell Automation control systems with modern PC-based platforms. Engineered for mission-critical manufacturing environments, this interface module enables seamless peer-to-peer communication, real-time data acquisition, and supervisory control across distributed automation architectures.

Technical Specifications

Interface Type: PCI bus (32-bit, 33 MHz)
Network Protocol: Data Highway Plus (DH+)
Communication Speed: 57.6 Kbps, 115.2 Kbps, 230.4 Kbps (auto-baud detection)
Node Address Range: 0-77 octal (configurable)
Cable Type: Belden 9463 or equivalent twin-axial shielded cable
Operating Temperature: 0 °C to 60 °C (32 °F to 140 °F)
Power Consumption: 5V DC @ 500 mA (supplied via PCI slot)
Compatibility: Windows XP/7/10, RSLinx Classic, FactoryTalk software suites
Diagnostic LEDs: Power, Network Activity, Module Status

Application Scenarios

SCADA & HMI Integration: Connect plant-floor PLC-5, SLC 500, and ControlLogix processors to PC-based SCADA systems for centralized monitoring, trending, and alarm management.

Legacy System Modernization: Bridge aging DH+ networks with contemporary Ethernet/IP infrastructures, preserving existing investments while enabling gradual migration to modern protocols.

Data Logging & Analytics: Capture high-resolution process data directly from controllers for predictive maintenance, OEE calculation, and quality assurance workflows.

Multi-Vendor Interoperability: Facilitate communication between Rockwell Automation devices and third-party DCS, historians, or MES platforms through OPC DA/UA gateways.

Key Advantages

Plug-and-Play Installation: Standard PCI form factor with automatic driver recognition in supported OS environments
Deterministic Performance: Token-passing protocol ensures predictable message delivery in time-sensitive control loops
Scalable Architecture: Support for up to 64 nodes per DH+ segment with repeater extensions
Industrial Hardening: Conformal coating and ESD protection for harsh factory conditions
Comprehensive Diagnostics: Built-in status indicators and software-based network health monitoring

Solution Highlights

The 1784-PKTX eliminates the complexity of serial-to-DH+ converters by providing direct PCI-level integration, reducing latency and simplifying troubleshooting. Its compatibility with RSLinx Classic enables drag-and-drop tag browsing, while FactoryTalk View SE leverages the card for real-time operator interfaces. For brownfield upgrades, the module coexists with newer 1756-ENBT Ethernet bridges, allowing phased network transitions without production downtime.

Ideal for power generation, automotive assembly, food processing, and petrochemical facilities requiring reliable DH+ connectivity in Windows-based control rooms.

Package Includes: 1784-PKTX PCI card, installation CD with drivers and documentation, quick-start guide.
