LADS for Techies

Laboratory Analytical Device Standard

LADS (Laboratory Analytical Device Standard) is an official Companion Specification of OPC UA, specifically developed for analytical and laboratory devices. Below are some key technical specifications of LADS:

  • Based on the OPC UA Standard:
    An established industrial standard for communication and interoperability in industrial automation.

  • Service-Oriented Framework:
    LADS leverages OPC UA’s core services, such as security management, session management, and event management.

  • Device-Type-Agnostic Modeling:
    LADS follows a device-agnostic approach to information modeling, addressing the diverse range of laboratory equipment.

     

  • High-Level Use Cases:
    LADS exposes information for selected high-level scenarios: (1) monitoring and control, (2) notifications, (3) program and results management, (4) asset management, and (5) maintenance.

  • Plug-and-Play Capable:
    LADS products work much like USB devices on a computer—ready to use with minimal setup.

  • Integration with Robotics and AI:
    LADS supports interoperability with adjacent fields, such as robotics and AI applications.

  • Platform Independence:
    It can be implemented on diverse hardware and software platforms, including traditional PC hardware, cloud-based servers, PLCs, and microcontrollers. 
  • Foundation for Extensions:
    LADS provides a basis for further specialized expansions, such as the “Common Analytical Instrument System Integration” (CAISI) specification.
Conclusion: LADS OPC UA offers standardized templates for the various elements of a device and its functions, along with clear rules for combining these parts.

OPC UA uses TCP/IP for network transport

UA Binary and UA XML are the primary data encoding formats that are used by OPC UA. Its multilayer architecture supports flexible protocol usage, accommodating technological advancements. OPC UA also provides robust tools, including browsers, software stacks for multiple programming languages, and comprehensive support.

Over 150 OPC UA Companion Specifications are available:

  • Foundational Specifications providing cross-industry standardized definitions for common elements.
  • Domain-Specific Specifications, such as LADS, addressing the unique needs of the laboratory and analytical sector.

Thanks to OPC UA’s object-oriented information modeling, a Companion Specification can seamlessly embed and reuse elements from existing cross-industry specifications.

LADS OPC UA and Cybersecurity

Connectivity interfaces represent a device’s primary attack surface and thus a primary focus for potential threats. OPC UA is widely used in critical infrastructures around the globe (e.g., power grids, water supply systems, power plants). Government agencies such as Germany’s BSI and the United States’ FBI pay close attention to security in OPC UA. The OPC UA Security Group—comprising more than 25 security experts from leading automation providers and IT companies—focuses on enhancing and advancing security technologies.

LADS automatically benefits from improvements made in OPC UA!
