• DHX Driver for all popular Allen-Bradley and SST DH, DH+, DH-485 and ControlNet network adapters.
• DHX Gateway Driver for remote access to all Allen-Bradley networks.
• ControlLogix Gateway Driver for remote access to Allen-Bradley DH+ through DHRIO.
• Ethernet DHX Driver for Allen-Bradley Ethernet communications.
• Serial DHX Driver for DF-1 communications.
• Virtual DHX Driver for enabling 16-bit legacy applications in 32-bit Windows.

OPC Server Features

The Only Choice For Mission-Critical Applications

The DHX OPC Server Suite has integrated fault-tolerant communication features not found in other OPC servers. Multiple, priority-based access paths can be used to build a true redundant communication architecture below the server level. The built-in Health Watchdog monitors the health of all network connections to all physical devices. The auto-switching access paths can be configured to quickly redirect communications to an unlimited number of plant-floor devices and networks.

Built for Performance

The DHX OPC server guarantees minimal load on the communication networks through advanced message transaction optimizers. In addition to server-level global optimization, the high-performance server also offers unsolicited data updates with advanced message filtering from unwanted data sources to ensure data integrity and security.

Packed with Intelligent and Powerful Features

Using Auto-configuration and DirectAccess™ features, a user can configure a minimal server setup with a single mouse click and gain access to all the registers in each network node without any user configuration. Power users can control many aspects of the server configuration. For enhanced security, write operations can be disabled for some or all of the data sources at data item, folder, device, device folder or network node levels. DirectAccess writes can also be disabled at each network node.

In version 7, DirectAccess feature supports redundancy. This allows all DirectAccess operations to switch seamlessly between redundant network nodes.

Includes All required Device Drivers

The DHX OPC Server Suite includes the DHX Driver Suite, the suite of communication drivers for DH, DH+, DH-485, ControlNet, A-B Ethernet, ControlLogix Gateway and DF1 networks.
