MBX OPC Premier Suite
DHX OPC Premier Suite
API for connectivity to Allen-Bradley networks and devices.

The DHX SDK includes the following software components:


The DHX SDK provides connectivity to DH, DH+, DH-485, ControlNet, A-B Ethernet, ControlLogix Gateway and DF1 networks and devices from 32-bit and 64-bit C and C++ applications.

The software provides access to Cyberlogic's high-performance DHXAPI interface for rapid development of applications targeted for all 32-bit and 64-bit Windows operating systems. The SDK includes interface libraries, sample source code, full documentation and all drivers to test applications.

All software applications developed with the DHX SDK are compatible with all DHX products. DHX Driver (for all Allen-Bradley and SST DH, DH+, DH-485 and ControlNet network adapters), the DHX Gateway (for remote access to all Allen-Bradley networks), the ControlLogix Gateway (for remote access to Allen-Bradley DH+ through DHRIO), the Ethernet DHX Driver (for Allen-Bradley Ethernet communications), the Serial DHX Driver (for DF-1 communications), the Virtual DHX Driver (for enabling 16-bit legacy applications in 32-bit Windows), the DHX OPC Server, and Math & Logic.
