The DHX architecture presents a consistent framework to
address different connectivity needs.

DHX Family Components

The Cyberlogic DHX family for Windows XP/2000/NT/Server 2003 consists of several well-integrated products that provide connectivity for Allen-Bradley’s Data Highway, Data Highway Plus, DH-485, ControlNet, and Ethernet networks in distributed environments.

Available Product Components
DHX OPC Server	Gives OPC clients access to Allen-Bradley networks.
DHX Driver	Device driver for Data Highway, Data Highway Plus, DH-485, and ControlNet adapter cards from Allen-Bradley and SST.
Ethernet DHX Driver	Driver for Data Highway Plus emulation over TCP/IP.
Serial DHX Driver	Full-duplex DF1 protocol driver for Allen-Bradley’s Data Highway, Data Highway Plus, DH-485, and ControlNet networks over serial COM port connections.
DHX Gateway Driver	Provides remote node access to Allen-Bradley’s Data Highway, Data Highway Plus, DH-485, ControlNet and Ethernet networks.
Virtual DHX Driver	Enables 16-bit legacy software to run in 32-bit Windows operating systems.
ControlLogix Gateway Driver	Provides remote access to Allen-Bradley's Data Highway Plus networks through 1756-DHRIO gateway modules in remote ControlLogix chassis.
DHX SDK	Software development kit for DHXAPI and 6001-F1E compliant development.

Blending DHX Supported Networks

All DHX components implement the same DHX architecture by exposing consistent and identical programming interfaces (DHXAPI and Allen-Bradley’s industry-standard 6001-F1E). This guarantees that an application that works with one DHX components (e.g. DHX Driver) will work with them all with no code modifications.

Migration of existing installations to new hardware products does not require the user to discard working, proven software solutions. As depicted in the following diagram, a user can now mix Data Highway, Data Highway Plus, DH-485, ControlNet, and Ethernet based hardware products in existing installations without losing software, network, and integration investment.
