Industry Applications
This communication card is well-suited for applications requiring reliable data exchange between PC-based control systems and legacy PLC networks. In manufacturing plants, it enables operators to monitor and configure PLC-5 and SLC 5/04 processors from a central workstation. The dual-port interface and 4 KB memory allocation ensure efficient data transmission and local network diagnostics.
Installation & Setup Guidance
To install the 1784-PKTXD, insert it into a PCI bus slot keyed for either 3.3-Volt or 5-Volt signaling. The universal PCI card feature ensures compatibility with most modern PC motherboards. After powering up the PC, the PCI BIOS assigns a base memory address for the dual-port interface, which requires up to 4 KB of memory. Ensure the card is properly seated and the Operating Network Status indicator functions as expected. For network configuration, use the appropriate Rockwell Automation software to set up DH+ or DH-485 parameters.
Maintenance & Reliability
Periodically inspect the card for dust accumulation and ensure the PCI slot connection remains secure. The 1784-PKTXD is designed for continuous industrial operation, but environmental factors such as temperature and humidity should be kept within the manufacturer's unspecified range. Regularly check the network status indicator to verify communication integrity. No specific maintenance intervals are provided; general best practices for PCI cards apply.
Compatibility & Integration
The 1784-PKTXD is compatible with PLC-5, PLC-5/250, and SLC 5/04 processors on the Data Highway Plus network. It also supports DH-485 networks for SLC processors. The card functions as a single-channel device for DH+, RIO scanner, and DH-485 protocols. Its universal PCI design ensures integration with various operating systems, making it a flexible choice for mixed-vendor environments.
Selection Guide & Purchasing Advice
When selecting a network interface card for legacy Allen-Bradley systems, the 1784-PKTXD offers a cost-effective solution for DH+ and DH-485 connectivity. Its 2-channel design and soft control support make it suitable for both new installations and upgrades. AutoDCSTech stocks this card and can provide lifecycle status and availability information.
