OPC Crosslink is a feature of Cyberlogic’s OPC servers that allows you to bridge data across any connected devices, whether they are OPC DA servers or PLCs. It is available in two packages: the OPC Crosslink Suite and the OPC Crosslink Premier Suite. The OPC Crosslink Premier Suite includes everything you get in the OPC Crosslink Suite, plus the OPC Math & Logic feature.
The OPC Crosslink Premier Suite allows you to bridge data between OPC servers, create an OPC data concentrator, or set up redundant OPC servers. The suite includes Cyberlogic’s OPC server and its OPC DA Driver Agent.
It communicates over Ethernet with any OPC server that is compliant to OPC Data Access specifications 3.0, 2.05a or 1.0a.
The server can be configured as an OPC data bridge, transferring data from one OPC DA server to another. Data read from an OPC server may be written to one or more other OPC servers, and may also be written back to the same OPC server. These transfers can be configured to occur at scheduled intervals, when the data changes, or when a trigger condition occurs. The source and destination DA servers need not be of the same brand or even of the same specification level. When combined with an MBX or DHX OPC Server, OPC Crosslink can even bridge data between OPC servers and PLCs, or between PLCs.
It can even bridge between Allen-Bradley and Modicon controllers.
Where system reliability is critical, the OPC Crosslink Premier Suite allows an unlimited number of OPC servers to be configured as redundant OPC servers. It does this by taking advantage of the integrated fault-tolerant features of the Cyberlogic OPC server. You can set up multiple, priority-based access paths to build a true redundant communication architecture. The built-in Health Watchdog monitors the health of all of these connections and automatically redirects communications among an unlimited number of redundant OPC servers.
The OPC Crosslink Premier Suite can also be configured as an OPC DA data concentrator, aggregating data from many servers into one. And because Cyberlogic’s OPC server complies with OPC Data Access specifications 3.0, 2.05a and 1.0a, it can obtain data from OPC servers that meet any of these spec levels, and can then provide it to OPC clients that require any of these levels.
In so doing, it serves as a specification level translator between mismatched servers and clients that could not otherwise work together.
Powerful configuration tools allow you to import the configuration from other OPC servers, configure a minimal server setup with just a few mouse clicks, and access all the tags in each OPC server without any user configuration. For enhanced security, you can disable write operations for some or all of the data sources at the data item, folder, device, device folder or network node levels.
The OPC Crosslink Premier Suite is built on Cyberlogic’s Universal OPC Server architecture, which is certified for compliance by the OPC Foundation’s Independent Certification Test Lab. As with all Cyberlogic software products, unlimited free technical support from Cyberlogic is included.

The OPC Crosslink Premier Suite gives you all of the benefits and capabilities of the OPC Crosslink Suite, but adds the powerful OPC Math & Logic feature:
OPC Math & Logic lets you write programs to perform mathematical or logical operations on any data items that are available to the OPC server. The results are available as OPC data to any attached OPC client. With OPC Math & Logic, you write the programs in the server, where all of the data is available in one location, so the programs can be written one time, with one editor, using one language. You won’t have multiple versions to maintain in multiple locations. Cyberlogic’s C-Logic™ programming language is similar to C, so it is easy to learn.
It also provides functions, data types, editing tools and debugging aids that you won’t find in PLCs or client applications. And because the programs are compiled, they run far faster than is possible with interpreted code.
