Configured for Data Highway Plus and Remote I/O network communication in PLC-5 platform environments, the Allen-Bradley 1784-PKTX (1784PKTX Network Interface Card) provides direct physical/electrical execution.

Nomenclature Breakdown & Identifier Configuration

• Base catalog identifier: 1784-PKTX
• Spare part designation: 1784PKTX
• Bus interface standard: Local PCI 2.3 compliant
• Supported protocols: Data Highway Plus (DH+), Remote I/O (RIO), DH-485

Hardware Specifications

Industrial Control & Drive Integration

The hardware architecture executes backplane bus communication velocity parameters designed for Allen-Bradley PLC-5 environments. Profinet and EtherNet/IP deterministic networks integrate smoothly with internal register maps via firmware flash compatibility protocols. Input and output density scaling parameters adapt dynamically to variable data traffic loads without degrading bus transmission integrity.

Ordering Information

• 1 x 1784-PKTX Network Interface Card hardware module
• 1 x Standard PCI mounting bracket assembly

Physical Installation & Electrical Wiring Guidelines

• Ensure the host computer system is completely powered down and disconnected from AC mains before inserting the PCI interface card into an available slot.
• Verify that base memory addresses and interrupt requests are correctly assigned through plug-and-play configuration to prevent resource conflicts.
• Route communication cables away from high-voltage power conduits and variable frequency drives to minimize electromagnetic interference on DH+ and RIO lines.
• Secure the card bracket firmly to the computer chassis to ensure a reliable low-impedance ground connection.

Frequently Asked Questions

• Q: Does this network interface card support live hot-swapping inside active computer systems?
• A: No, hot-swapping is not supported. The host workstation must be completely powered off before installing or removing the interface card.
• Q: How many communication channels are provided on the standard 1784-PKTX model?
• A: The card provides a single protocol channel with two physical ports supporting selective connections to DH+, DH-485, or Remote I/O networks.
• Q: What specific bus standard does the hardware interface comply with?
• A: The module complies fully with local PCI version 2.3 specifications and requires a compatible desktop PCI expansion slot.
• Q: Can this card be used to interface with Man/Machine Interface applications?
• A: Yes, it can be configured to support MMI software operating on either Data Highway Plus or DH-485 network architectures.
• Q: What is the maximum number of these interface cards permitted within a single system?
• A: The system architecture allows a maximum limit of up to 4 modules operating concurrently.
• Q: Are firmware updates supported for adapting to evolving software platforms?
• A: Yes, firmware flash compatibility allows version updates using authorized configuration utilities to maintain software driver alignment.
• Q: What is the difference between the 1784-PKTX and the older 1784-KTX model?
• A: The KTX card is an older legacy ISA-bus version, whereas the PKTX is its direct successor designed for modern desktop PCI expansion slots.
• Q: What operating system environments are typically supported with appropriate driver software?
• A: The hardware functions with legacy platforms such as Windows 95, Windows NT, MS-DOS, and Windows 3.x using RSLinx or custom driver packages.
