EtherNet/IP and PLC Communication Interface Characteristics
The 1784-U2DHP provides USB-based access to Data Highway Plus network nodes through a workstation interface. The module manages DH+ communication timing and data exchange between USB-connected computers and PLC-5 or SLC 5/04 controllers. Communication speed selection is dependent on network distance and DH+ physical layer conditions.
The module supports PLC programming and configuration operations through compatible Allen-Bradley software environments. The interface hardware provides status indication through integrated LED diagnostics for USB power availability and DH+ network communication activity.
Frequently Asked Questions

A: The module supports 230.4 Kbps at shorter distances up to 762 m, 115.2 Kbps up to 1524 m, and 57.6 Kbps up to 3048 m.
Field Installation Guidelines
Install the 1784-U2DHP on a workstation side connection point with the USB cable connected directly to the programming computer and the DH+ interface connected to the network segment.
Route DH+ communication wiring separately from high-voltage power cables, motor leads, and high-frequency switching conductors to reduce electrical interference. Maintain proper cable shielding practices according to the DH+ network installation requirements. Verify connector seating, network termination conditions, and communication status LEDs before commissioning.
Avoid installing the communication module in locations exceeding the specified operating temperature range or enclosure protection limitations. Confirm compatible controller firmware and programming software support before establishing PLC communication.
