The 1784-PKTX functions as a high-performance PCI-bus network interface card. Fully adherent to PCI 2.3 specifications, this hardware enables dual-network connectivity, providing dedicated ports for Data Highway Plus (DH+) / Remote I/O (RIO) on Channel 1A, alongside a DH-485 port on Channel 1B. It delivers reliable legacy network aggregation directly to industrial and desktop computer systems.
Built to standard PCI 2.3 hardware specifications
Direct access to Data Highway Plus (DH+) and Remote I/O (RIO) architectures
Secondary dedicated link for DH-485 industrial networks
The 1784-PKTX acts as a critical network interface by providing a rugged and direct physical layer link between the host PC and field-level hardware, allowing programming, monitoring, and data acquisition software like RSLogix 5/500 and various HMI/SCADA packages to communicate seamlessly with legacy on-site processors, including Allen-Bradley PLC-5, SLC 500, and MicroLogix controller families.
This interface card incorporates a dual-channel architecture that enables simultaneous or selective network operation across multiple proprietary protocols. Channel 1A supports Data Highway Plus (DH+) and Universal Remote I/O (RIO) communications, executing either scanner or adapter functionality to manage decentralized I/O racks via standard 1770-CD blue hose cabling, while Channel 1B provides a dedicated network link for DH-485 industrial communication networks.
To prevent hardware resource conflicts with other peripheral components inside the host computer, the card features on-board DIP switches that allow precise manual configuration of the base input/output (I/O) memory addressing location. Additionally, the front panel includes diagnostic LED status indicators that display real-time network activity and connection health, facilitating rapid field troubleshooting and ensuring maximum operational uptime in high-demand industrial processing environments.

Automotive Assembly and Stamping
Connects an industrial PC running HMI/SCADA software to older PLC-5 controllers via Data Highway Plus (DH+) to gather production cycle times and weld quality diagnostics.
Oil and Gas Refining
Interfaces a host data archiving server with decentralized SLC 500 processors over a DH+ network to monitor real-time fractional distillation temperatures and pressure limits.
Iron and Steel Production
Establishes a rugged physical layer link from a programming workstation to legacy field processors, enabling engineers to upload or modify control code using RSLogix 5.
Chemical and Petrochemical Processing
Pulls real-time critical temperature profiles and raw material weight calculations from chemical mixing stations back to an enterprise asset management database.
Pulp and Paper Mills
Acts as a communication gateway in a centralized maintenance PC to track steam pressure and roller speed variables over a DH+ network.
Traditional Power Generation
Connects localized control room PCs to field PLC-5 or SLC racks over a secure DH+ topology to coordinate belt feeders and conveyor routing.
When operating the 1784-PKTX1 interface card, insert the hardware completely into a compatible 5V standard PCI slot and manually configure the correct base address via the on-board DIP switches to eliminate hardware resource and interrupt (IRQ) conflicts with other peripherals in the operating system. Given its status as legacy hardware, operators must strictly verify operating system compatibility, as this card typically supports only 32-bit Windows systems and specific versions of RSLinx Classic drivers. Furthermore, when linking to field networks, assign the correct node address and network baud rate for the DH+ or Remote I/O (RIO) channels, and install matching termination resistors at both ends of the cable to prevent signal reflection and communication failure.
The Allen-Bradley 1784-PKTX is a PCI 2.3 compliant dual-channel industrial communication card utilized to interface computers with legacy networks. Channel 1A supports DH+ and Remote I/O (RIO) protocols, while Channel 1B accommodates DH-485 communication. This card delivers stable, low-latency data connections for host HMI, SCADA, and programming software via the PCI bus, serving as a critical network interface bridging modern PCs with legacy on-site controllers like the PLC-5 and SLC 500 series. For more parameter details, please refer to Powergearx.
It is a PCI-bus-based industrial communication interface card used to connect a desktop computer or industrial PC to Allen-Bradley DH+ (Data Highway Plus), DH-485, or Remote I/O (RIO) networks.
What is the primary use of the 1784-PKTX1?
It is primarily used for data communication between PC-based programming software (such as RSLogix 5/500) or HMI/SCADA software and on-site PLC-5, SLC 500 controllers, or Remote I/O devices.
How many communication channels does the 1784-PKTX1 support?
The 1784-PKTX1 is a single-channel communication card. For dual-channel functionality, the 1784-PKTX card is required.
What hardware slot interface does the 1784-PKTX1 use?
It uses a standard 5V PCI slot interface, typically installed into a conventional PCI slot on a computer motherboard.
How do you install the 1784-PKTX1 hardware in a computer?
First, power off the computer, open the chassis, insert the 1784-PKTX1 firmly into an available PCI slot, secure the bracket with a screw, and then restart the computer.
