Preparing to Integrate IIoT: How can controls, automation, and instrumentation help with integration and use of Industrial Internet of Things (IIoT) technologies?
As advances in technology make it more cost-effective to deploy IIoT, industries will need to acquire a strategic approach to integrating new sensor data with pre-existing data environments.
Now, more than ever, industries are seeking simple integrations with controls, automation, and data analytics visualization software to harness the power of the Industrial Internet of Things and realize attractive operational and competitive benefits for their business. IIoT can unite people and systems on the plant floor with those at the enterprise level, and enable users to get the most value from their automated systems while reducing technological and economic limitations. To ensure successful deployment of the IIoT, industrial organizations can benefit from embracing new network design infrastructures, including developing a reliable framework that supports collaborative work processes across functional lines, as well as between internal and external resources.
New systems to integrate IIoT
Processes, digital devices and business systems can support implementation of the Industrial Internet of Things, from small companies new to the IIoT potential up to large industries that can benefit from adding new sensors into their present systems for internal and external assets. From laying the foundations to help guide future technology investments to easing the integration of the current systems with new controls, automation and data processing benefits, there are ways to help smooth the process and transition for getting the desired results. When looking at new systems for IIoT implementation, it is recommended to examine the following seven areas for benefits:
1. Assess the Baseline: Look at assets, processes, data collection, analytics, and real-time visibility to assess the ability to predict and detect issues and opportunities; for example, which types of sensors, cameras and other instrumentation are available to make use of available data tracking potentialities?
2. Boost the Capabilities: Use machine learning, Big Data, and automation technologies to create an über-system that can accurately and consistently capture, analyze, and transmit data with visualized dashboards for operations management.
3. Integrate the Potential: Employing open integration and communications technologies can help connect data from varied sources on the way to extracting meaningful value for decision-making. This can include software that brings high fidelity data from disparate operational sources to people in all corners of a clients’ enterprise – wherever, whenever and however it is needed.
4. Consolidate Data: Look to centralizing data in the Cloud with new applications that connect multiple disparate systems, applying higher level analytics and leveraging expertise with the benefits of being physically remote from the operating site.
5. Make it Visual: Consider employing cloud-based applications that add value, such as advanced process control (APC) monitoring, condition-based monitoring (CBM), enterprise data historians, mobility solutions, and planning and scheduling tools. This new instrumentation can help facilitate real-time decision making plus allow long-term data tracking for precise adjustments
6. Re-define Teamwork: With these new controls and automation tools, look to define how functional groups can work together and how to enable smart collaboration across the organization using IIoT advantages; this may include sharing data in operations, maintenance, system reliability, supply chain management, and other potential synergies.
7. Make Alliances with the Experts: Stay flexible with new updates and demographic changes using technology tools and collaborations with third-party experts that understand industrial automation, process data, and control-related issues across the enterprise. Traditional information technology (IT) providers may not offer that depth, and the potential for niche integration consultants is ripe for growth.
Potential Challenges and Hurdles
Integrating new technologies into existing environments can present unique challenges to overcome. While connecting legacy equipment and systems offers potential big benefits and is an important step in the IoT initiatives at many industrial companies, the hurdles to implementation can be notable in the process.
Having said that, many companies are making important strides in this area. How are they doing it? One of the challenges they faced in the presence of legacy machines was the lack of connectivity built into legacy machines. Companies are now adding stand-alone sensors and cameras to existing environments and devices to monitor and collect data about performance and health in new ways, like attaching the sensors directly to the existing devices and connecting new gateways to securely collect and transmit the data, which is then analyzed and used to help boost various areas of the business while preventing failure and downtime.
One of the lingering questions being, if legacy machines don’t have sensors and automation controls built into them today, how can they be attached in a cost-effective manner? The following answer would enable teams to begin measuring things like vibration, temperature, climate, dust in the air and other factors that are useful for quality environments where the machines are deployed. Cameras also can play a big role, enabling the monitoring ability of team members through a common platform to tap open a video and get a real-time sense for where a machine is and how the operation is functioning.
With the increased integration of global intelligent manufacturing, companies are turning to IIoT architecture as the core of the platform strategy to ease integration. Various companies are designing solutions as a three-layer architecture, offering neither an IIoT platform nor simply an industrial cloud platform, yet a fully connected system.
- Bottom Layer: this would include various hardware products with interconnectivity capacity, like gateways and more.
- Intermediate Layer: this would take care of edge point control.
- Upper Layer: this would comprise various applications, analytics, and services for decision making capabilities.
The system works together and these three layers are not mutually independent. The reality is that IIoT only can be realized through intercommunication of these three layers regarding information, data, communications, and applications, and in these cases, software platforms at the operating system level are needed to support and connect the three-layer architecture.
Conclusions and Next Steps
As more hardware devices go online, more opportunities abound for engineers to assist with the integration and novel use of controls, automation, and instrumentation across industries. Following the simple steps of assessing company assets and capabilities, to reviewing potential benefits and ways to ease integration can benefit the whole enterprise.
