Scope / Goals
Develop an OPC UA Information Model for a Common Analytical Instrument System Integration (Abbreviation “CAISI”). It will allow integrating analytical instrument systems into analytical data systems (e.g., Chromatography data systems, aka CDS) to execute analytical runs.
Main purpose is being able
- to compose analytical physical devices/instruments (so-called Physical Instrument Controllers, aka “PIC”)
- into a logical analytical instrument system (so-called Logical Instrument Controllers, aka “LIC”)
- and exposing analytical instrument information to OPC UA applications, for example for integration purposes into analytical data systems (e.g. chromatography data systems, aka “CDS”).
The working group will initially focus on Liquid Chromatography (LC), Gas Chromatography (GC), and associated detectors including single quad mass spectrometer (MS).
It will collaborate with the “Laboratory and Analytical Devices (LADS) Joint Working Group” to provide a common model for the instrument device level (called Physical Instrument Controller (PICs).
Today’s situation
- In a typical lab you will find a mixed assortment of analytical instruments controlled by different data systems
- The Instrument connectivity into these data systems is vendor specific and requires significant integration effort by each data system and instrument system vendor, because each vendor uses a different set of drivers and data models
- OPC-UA CS LADS was a first important step and now also ASI w/ CAISI contributes to the standardization for the analytical lab
- CAISI has the goal to provide companions specs so that analytical instrument device drivers can be plugged into instrument system component. The instrument system component itself integrates via CAISI into the analytical data system.
