FAQ
FAQ
Q1: What is the Allen-Bradley 1784-U2DHP used for?
A: The 1784-U2DHP is used to connect a computer’s USB port to an Allen-Bradley Data Highway Plus (DH+) network, allowing engineers to configure, program, monitor, and troubleshoot compatible PLC systems.
Q2: Which controllers are compatible with the 1784-U2DHP?
A: The adapter supports PLC-5 processors (except Classic PLC-5 models such as PLC-5/10, PLC-5/12, PLC-5/15, and PLC-5/25) and SLC 5/04 processors connected through a DH+ network.
Q3: What communication speeds does the 1784-U2DHP support?
A: It supports three DH+ network data rates: 57.6 kbps, 115.2 kbps, and 230.4 kbps, allowing compatibility with different DH+ network configurations.
Q4: Does the 1784-U2DHP require an external power supply?
A: No. The adapter is powered directly from the computer’s USB port, requiring a nominal 5 VDC supply with a maximum current of 125 mA.
Q5: Which software can be used with the 1784-U2DHP?
A: It is commonly used with RSLinx Classic to establish DH+ communications and works with programming software such as RSLogix 5 and RSLogix 500 for supported controllers.
Q6: What are the dimensions and weight of the 1784-U2DHP?
A: The adapter enclosure measures approximately 76.2 × 50.8 × 25.4 mm, the DH+ cable is 2.44 m (8 ft) long, the USB cable is 0.61 m (2 ft) long, and the unit weighs approximately 0.17 kg.
Q7: Can the 1784-U2DHP replace the older 1784-PCMK interface?
A: Yes. The 1784-U2DHP is the recommended USB-based replacement for the legacy 1784-PCMK PCMCIA communication card, providing equivalent DH+ communication without requiring a PCMCIA slot.
Q8: What should be checked before using the 1784-U2DHP?
A: Verify that the appropriate USB driver and RSLinx Classic software are installed, confirm the correct COM port assignment, select the proper DH+ communication rate and node address, and ensure the target PLC and DH+ network are correctly wired before establishing communication.
