Product Introduction
The Allen-Bradley 1784-PKTXD PCI Network Interface Card is an enhanced industrial communication interface designed for desktop PCs that require multi-channel connectivity to legacy Allen-Bradley control networks. It provides a reliable and structured solution for integrating engineering workstations into DH+, DH-485, and Remote I/O systems.
Compared to single-channel communication cards, the 1784-PKTXD introduces expanded channel capability, allowing simultaneous interaction with multiple network segments. This makes it particularly suitable for complex systems where multiple communication paths must be maintained at the same time.
The card operates through a PCI interface compliant with version 2.3, ensuring stable data transfer and compatibility with industrial-grade PCs. It features multiple Phoenix connectors, with two channels dedicated to DH+ and Remote I/O, and one channel for DH-485 communication.
Each channel is equipped with a diagnostic LED, allowing quick identification of communication status and faults. With support for up to four modules per system and flexible driver integration, the 1784-PKTXD is widely used in system maintenance, commissioning, and long-term operation of legacy automation infrastructures.

Used in control rooms where one PC needs to access several controllers across different network segments.
● Legacy system support and maintenance
Provides stable communication with older Remote I/O and DH-485 systems still in operation.
● Industrial communication diagnostics
Enables detailed monitoring of multiple channels for fault detection and system analysis.
● Program management and data exchange
Supports reliable uploading, downloading, and monitoring of PLC programs across different networks.
Advantages
● Triple-channel communication capability
Supports two DH+/RIO channels and one DH-485 channel, enabling flexible network architecture.
● High system integration efficiency
Reduces the need for multiple interface cards by combining several communication paths in one module.
● Stable PCI-based communication
Direct PCI interface ensures consistent data transfer and low latency.
● Scalable configuration
Supports up to four cards per system, allowing expansion in large installations.
● Built-in diagnostic indication
Each channel includes a status LED for real-time monitoring and troubleshooting.
● Flexible driver compatibility
Works with RSLinx PKTx driver and specialized RIO drivers for different communication requirements.
FAQ
- How are multiple DH+ channels managed on this card?
Each DH+ channel operates independently and is configured through the communication driver, allowing separate network addressing and communication paths. - Can the two DH+/RIO channels be used simultaneously?
Yes, both channels can run at the same time, enabling the PC to communicate with multiple DH+ or RIO networks concurrently. - What determines the maximum number of cards installed in one system?
The limit is controlled by hardware jumper settings on each card, ensuring proper addressing and avoiding conflicts. - How is DH-485 communication handled differently from DH+?
DH-485 uses a separate channel (CH 1C) with its own connector and configuration, optimized for lower-speed serial communication. - What role do the diagnostic LEDs play during operation?
They provide immediate visual feedback on channel activity, communication status, and potential faults, simplifying troubleshooting. - How is Remote I/O communication configured?
Remote I/O is managed through the 6001-RIO driver, which handles data mapping and communication between the PC and remote racks. - Can this card be used in modern operating systems?
Native support is limited, and using newer systems typically requires custom driver development or legacy environments. - What happens if communication conflicts occur between channels?
Proper configuration of network parameters and addressing ensures that channels operate independently without interference. - How does the PCI interface improve performance?
The PCI interface provides direct communication with the system bus, resulting in faster and more stable data transfer compared to external interfaces. - Is the card suitable for continuous industrial monitoring?
Yes, it is designed for stable long-term operation, supporting continuous data exchange and monitoring across multiple networks.
