The xCoupler enterprise transaction module for use with Allen-Bradley ControlLogix PLCs is the first in a series of such modules designed to snap into the backplane of PLCs to provide two-tier data exchange between plant floor devices connected to the controller and enterprise servers.
To eliminate PC-based interfaces that are commonly used to transfer data, xCoupler communicates directly from ControlLogix to enterprise servers in their native languages. Popular server communications interfaces currently available for the xCoupler include IBM WebSphere MQ and DB2, Oracle, Microsoft SQL, SMTP and TCP/IP. Configuring modules to map data values from factory floor controllers to the enterprise is done using the WorkBench software tool. It uses a drag and drop configurator and requires no programming skills, says the vendor. In addition to simple and fast operation and setup, xCoupler modules eliminate the security, virus and data integrity problems associated with PC-operated multi-tier systems connected to the enterprise.
