OPC Foundation Announces Sucessful Data Exchange Using ADI Information Model
06/15/2009
The OPC Foundation has announced the successful demonstration of data exchange between applications using the OPC UA Analyzer Device Integration (ADI) information model.
ebizQ received the following:
OPC Unified Architecture provides a base foundation of services for discovery, read/write and subscription for information that is described by industry standards organizations focused on information modeling. The OPC Unified Architecture Analyzer Device Specification will leverage the information model architecture of OPC UA facilitating complete data access and exchange services with secure transactional capability via the SOA (Service Oriented Architecture) for configuration data, diagnostic data, and runtime operational data for all analyzer devices.
The OPC Foundation released the draft ADI Specification for review in December 2008. This new specification provides a common data exchange method for process and laboratory analyzers. Developed as a logical extension of the OPC UA specifications, the OPC ADI Specification serves as an information model for analyzer devices and enables true plug-and-play multivendor interoperability. Analyzer integration based on standards offers a unique opportunity in Data Management and Integration for solutions such as Process Analytical Technology (PAT).
The OPC UA information model is a specific design of OPC UA objects that represent data in an analytical industry domain. This first-time display of an ADI Server integrated with an OPC UA client is an important milestone towards meeting the reference implementation requirement for OPC UA ADI specification approval.
ABB developed an ADI software model and implemented a server representing an ADI capable spectrometer device. Results of the reference implementation efforts prove that the ADI specification can be implemented in a way that enables connectivity with virtually any OPC UA client, says Voytek Janisz, Systems Architect at ABB.
The OPC Foundation working group, composed of end-users and vendors, collaborated to define and finalize the specification. The working group has grown from several founding members to a large multi-industry group that includes large pharmaceutical and food companies and vendors of analytical devices, control systems and integration software. The working group represents both Process Analytical Technology (PAT) and laboratory industries.
"The OPC Unified Architecture was specifically designed to host higher level information models such as ADI. This demonstration proves that we have succeeded in our goal to enable seamless interoperability at a much higher semantic level than ever before, which will usher in a new era of cost savings enjoyed by both end-users and vendors," said Thomas Burke, President of the OPC Foundation.
