Highlights of the 1784-U2DHP
Replacing Legacy 1784 Cards: It is mostly used for PLC programming with RSLINX communications with PLC-5s and SLC 5/04s on Allen-Bradley Datahighway Plus (DH+) that replaces now obsolete 1784 interface cards like the 1784-PKTx, 1784-KTX, and 1784-PCMK cards.
Software Application: The 1784-U2DHP interfaces with Rockwell Automation software, like RSLogix 5 and 500, and RSLinx Classic. These software packages facilitate the programming, data collection, and diagnostic tasks for PLCs connected via the DH+ network.
Connectivity and Speed: The device connects to a computer via a USB interface and links to the DH+ network through its 9-pin D-shell connector. It supports DH+ communication speeds of 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps.
Ease of Installation and Use: The device is known for its straightforward installation process. Once the drivers are installed, the 1784-U2DHP is typically recognized by the relevant software, allowing for easy configuration.
