Interoperability in the Spotlight - how Different Standards Compare
As Industry 4.0 evolves, one of its key aspirations is to cut integration costs when introducing new data players in enterprises. Standards such as "OPC UA" and "MQTT" have been spotlighted as potential solutions. However, just using these standards doesn't necessarily lead to interoperability. The widely-accepted TCP Model, while facilitating global connectivity, is vague on specific communication protocols and encodings. Its focus is mainly on the Application Layer.
Contrarily, the Data Access Model offers a more in-depth look. It merges network components into a single Transport Layer and categorizes the application part into six detailed layers. How compatible these layers are with each other becomes the measure of interoperability.
MQTT, established in 1999, gained fame for its ability to efficiently disseminate data in bandwidth-constrained scenarios. Its relevance skyrocketed around 2011 when IT giants realized its scalability potential, propelling it into mainstream tech applications. On the other side, the OPC Foundation launched the OPC UA specification in 2006, which revamped connectivity features and was adopted widely. While the OPC Foundation continuously strived for interoperability, the intricate array of specifications at each layer can be challenging.
For "MQTT", the challenges stem from its ambiguous data stack, complicating integration tasks for engineers. Meanwhile, OPC UA, despite its comprehensive standardization, presents a maze of customizations that can hinder true integration.
In essence, genuine interoperability can't be achieved by simply banking on "OPC UA" or "MQTT" as magic bullets. The current scenario in the data access realm is eerily reminiscent of past protocol battles. A well-defined structure in the Data Access Model is crucial. Without it, OEMs may produce mismatched solutions, and end-users might find themselves navigating a complex tech labyrinth.
Just because two machines “speak” OPC UA doesn’t mean they can cooperate straight out of the box. In 99% of the cases, additional efforts are necessary to achieve interoperability, entailing the elaboration and determination of the requisite details for each specific case, which can be very labor-intensive.
omlox: The Gold Standard in Interoperability and Integration
In an age where the term "standard" is bandied about in the industrial data access world, few truly understand its depth. Standards like OPC UA and MQTT indeed have a role in the orchestration of communication protocols. They tell us how to communicate but leave much ambiguity when it comes to the content of communication. It's akin to defining the envelope but not the letter inside. This vagueness often leads to strenuous integration efforts and compatibility issues.
Enter omlox, the open locating standard that promises to take a more intricate approach. omlox doesn’t just stop at the envelope; it details the entire letter inside, standardizing not only the method of communication but also the data being transmitted and its format. It's more comprehensive, more efficient, and ultimately, more effective.

Why omlox Stands Out
omlox transcends traditional standards. It's comprehensive, leaving nothing to serendipity. With omlox, you're assured that software and hardware compatibility isn't just a promise, but a reality. The cumbersome integration issues common with OPC UA, where two devices communicating through OPC UA might still need painstaking custom work to truly understand each other, are absent in the omlox universe.
In OPC UA and the various industry-specific OPC UA Companion Specs, the positioning of objects is not clearly defined. Sometimes it's represented as text, sometimes as XY coordinates, sometimes as GPS, and sometimes relative to another object. For this reason, omlox has initiated the working group "Global Position", which defines location information uniformly for OPC (as a Companion Spec). This enables location data from omlox-based systems to be seamlessly integrated with machine data from OPC.
omlox is not just a theoretical standard; it's a tangible, working solution. Its dual core components exemplify this. The "omlox hub" is a trailblazing middleware that amalgamates location data across all locating technologies and manufacturers, providing a unified, standardized interface. Whether it's indoor or expansive outdoor spaces, omlox ensures seamless localization. On the other side, omlox's "core zone" leverages ultrawide-band technology (UWB) to pinpoint objects, even in complex environments. And with its open architecture, users can integrate hardware from various manufacturers, ensuring cost efficiency.
To ensure that this gold standard remains polished, the reins of omlox's management and development have been handed to the masters: PROFIBUS & PROFINET International (PI), the world's most expansive automation community. With PI's rich legacy and expertise, omlox is set to remain at the forefront of interoperable solutions.
Flowcate & omlox: A Recipe for Success
As one of the pioneering entities behind the omlox standard, Flowcate stands out with its groundbreaking omlox-compliant middleware, the DeepHub.
DeepHub is a testament to omlox's vision, aggregating location data from myriad sources, converting it into standardized coordinates, and making it accessible through a standardized API. With its capability to bridge indoor and outdoor location data, and facilitate geofencing functionalities, the DeepHub showcases true interoperability. It’s not just a product, but a beacon of what omlox seeks to achieve: seamless integration, lower costs, and enhanced operational efficiencies.
The world is catching on to this paradigm shift. The omlox partner ecosystem, with the DeepHub as its nucleus, is expanding globally. Whether you're a system integrator, solution provider, or a software/hardware vendor, omlox and Flowcate have got you covered.
In conclusion, while the industry has been rife with standards, omlox, with its encompassing nature, is setting a new benchmark. Backed by industry giants, the promise of genuine interoperability and minimal integration efforts is not just a dream but a rapidly unfolding reality.
