Features:
- PCI-based industrial communication interface supporting Data Highway Plus and DH-485 networks
- Plug-and-play configuration with dual-port memory for efficient data transmission and diagnostics
- Compatible with PLC-5, SLC processors, and ControlLogix systems via 1756-DHRIO integration
The Allen-Bradley 1784-PKTX plays an important role in bridging PC-based systems with traditional Allen-Bradley industrial controllers. It enables communication over Data Highway Plus and DH-485 networks, supporting integration with PLC-5 and SLC processor families. This makes the 1784-PKTX suitable for industrial environments where legacy systems remain in operation alongside modern control platforms. Its PCI-based architecture allows installation directly into standard industrial computers. As a result, it provides a practical solution for maintaining connectivity across mixed-generation automation systems.
In operational use, the 1784-PKTX handles data transmission, network diagnostics, and communication management through dual-port memory architecture. The system relies on RSLinx software to coordinate data exchange between the host PC and connected industrial devices. This ensures stable communication performance even in complex network configurations. The 1784-PKTX can function as a remote I/O scanner, expanding its role beyond simple data exchange. Its flexibility supports both programming and real-time monitoring applications in industrial control environments.
From a system integration perspective, the Allen-Bradley 1784-PKTX supports multiple connection methods, including direct PLC links and multi-node DH-485 networks. It can be connected to PLC-5 processors using dedicated cabling or integrated into SLC networks through link couplers and daisy-chain configurations. The card supports up to four modules per system, allowing scalable communication setups. With robust environmental tolerance and PCI plug-and-play configuration, the 1784-PKTX delivers reliable performance in continuous industrial operation scenarios.
The 1784-PKTX Allen-Bradley Data Highway Plus PC Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Traditional Workshop Upgrade Monitoring (SCADA): In the renovation of old factories, this connects the new industrial PC in the central control room to the PLC-5 production line that has been running for many years for centralized data acquisition.
- PLC Programming and Debugging Workstation: Technicians use portable industrial computers or desktops equipped with this card to upload, download, and debug programs for the entire plant's SLC 500 controllers online via a DH+ network.
- Main Computer Remote I/O Scanner: In specific open control systems, the industrial PC is virtualized as a remote I/O scanner, directly controlling remote 1771 or 1794 I/O frames via a RIO network.
- Heterogeneous Network Data Gateway: In large-scale distributed system architectures, it serves as the physical core of the protocol conversion gateway, responsible for bridging the communication gap between the old DH+ network and the new plant-level Ethernet (EtherNet/IP).
- Dual-channel heterogeneous network: Supports independent or simultaneous configuration of Data Highway Plus (DH+), DH-485, and general-purpose remote I/O (RIO) networks on a single card, enabling multi-protocol physical layer bridging.
- High-speed backplane switching: Enables high-frequency data exchange with industrial PCs (IPCs) via a standard PCI bus interface, seamlessly delivering data frames from the field industrial network layer to system memory.
- Token ring network arbitration: Features a built-in dedicated communication processor that automatically participates in node ordering, token passing, and occasional collision detection in the DH+ token ring network architecture.
- Dynamic baud rate adaptation: The physical channel is fully compatible with the DH+ network standard's 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps transmission rates, and supports software switching via hardware jumpers or drivers.
- Smooth Integration with Legacy Systems: Allows modern Windows-based industrial PCs to directly access older PLC-2, PLC-3, PLC-5, and SLC 500 series legacy controller platforms.
- Multi-Generation Driver Backward Compatibility: Perfectly compatible with the proprietary 1784-PKTX(D) driver package built into the RSLinx Classic software, providing a stable DDE/OPC data communication interface.
- Standard PCI Slot Specification: The hardware adopts a low-profile physical card structure conforming to the PCI standard, allowing direct insertion into industrial computers with traditional 5V or 3.3V universal PCI expansion slots.
- Third-Party Software Access: Supports not only Rockwell's own FactoryTalk software but also provides physical layer hardware access for standard-compliant third-party SCADA monitoring systems and Human Machine Interfaces (HMIs).
