Allen Bradley 1784-PKTX PLC 5 Network Interface Card
The Allen Bradley 1784-PKTX is a bus communication network interface card designed to plug directly into a PCI 2.3 compliant slot on a host computer. This hardware module enables desktop or industrial PCs to interface with legacy Allen-Bradley networks, including Data Highway Plus (DH+), Remote I/O (RIO), and DH-485 protocols. It provides maintenance and engineering personnel with a reliable physical gateway for running configuration software, performing programming tasks, and implementing real-time process visualization across PLC-5 and SLC controller architectures.
Network Communication Channels
The module features two physical communication interfaces designated as Channel 1A and Channel 1C. Channel 1A utilizes a 3-pin Phoenix connector to support both DH+ and Remote I/O networks, while Channel 1C uses a 6-pin Phoenix connector dedicated to DH-485 communication. Each channel features an independent diagnostic and status LED indicator to monitor network traffic and operational health. Up to four (4) modules can be installed and configured within a single host system depending on jumper settings and system resources.
Cable Length and Baud Rate Specifications
Communication distance varies inversely with the selected baud rate across all supported protocols. For DH+ and Remote I/O links, the maximum cable span reaches up to 10,000 feet (3048 meters) at 57.6 kbps, scales down to 5,000 feet (1524 meters) at 115.2 kbps, and supports a maximum speed of 230.4 kbps over a distance of 2,500 feet (762 meters). For DH-485 networks, the card supports a maximum trunkline distance of 4,000 feet (1219 meters) at baud rates of 1.2, 2.4, 4.8, 9.6, or 19.2 kbps.
Controller Compatibility and Software Drivers
The 1784-PKTX interfaces directly with PLC-5, PLC-5/250, and SLC 5/04 processors, as well as SLC 5/01, SLC 5/02, and SLC 5/03 processors when routed through a 1785-KA5 interface module. Software communication relies on the RSLinx PKTx driver for standard Windows environments to manage device polling. Physical connection to DH+ networks is typically established using the 10-foot (3.2-meter) 1784-CP12 cable equipped with a 3-pin Phoenix connector and switchable termination resistor, whereas DH-485 connections utilize the 1784-CP14 cable featuring a 6-pin Phoenix connector.
