Overcoming the Challenges of OPC for Industrial IoT Applications

Gain Greater Flexibility, Lower Latency and Accelerate Time to Value with Telit deviceWISE®

Keeping Pace in a Connected Manufacturing World

Manufacturing is undergoing a major revolution. The Internet of Things (IoT) is driving the change, using lightweight, low-power sensors to connect devices across the factory floor. Today’s industrial environments are connected and mobile, creating substantial business benefits potential. The Aberdeen Group found that 74% of best-in-class companies can collect and aggregate sensor data in real time.

Companies are monitoring and analyzing factory floor performance to improve processes and bring analytics to previously isolated data. Informed by these insights, manufacturers can examine their supply chains and processes and look for ways to accelerate innovation.

Current technologies are restricting manufacturers’ ability to realize IoT’s promise. One of the most limiting factors lies with the existing communications standards. Many manufacturers rely on Open Platform Communications (OPC). OPC has been a key interoperability standard for communications since 1996. Although useful, this aging standard by itself can’t keep pace with today’s changing needs.

Manufacturers need a better way to connect their organizations and make the most of the IoT revolution. They must quickly establish connectivity from shop floor to top floor — and their ecosystems.

The answer is Telit deviceWISE. In this paper, you’ll learn how deviceWISE far surpasses OPC. You’ll discover why deviceWISE is ideal for manufacturers seeking to address top challenges and get ready for new ones.

It’s Time to Think Beyond OPC

OPC is the standard approach for supervisory control and data acquisition (SCADA) and human-machine interface (HMI) systems to interface with programmable logic controllers (PLCs). The original OPC specification was tied to the Microsoft Windows operating system (OS). OPC Data Access (OPC DA) and Microsoft took connected manufacturing a significant step forward.

Using OPC DA in today’s manufacturing climate poses several challenges. OPC’s underlying technology is so aligned with Microsoft that it isn’t compatible with many other technologies. As OSs like Linux become prevalent in manufacturing, companies relying on OPC DA can find their interoperability plans thwarted.

Dynamics is another pain point. OPC is designed to constantly interrogate devices. It consumes significant compute time and hampers efficiency, limiting throughput and scalability. Supporting the frequent polling process requires additional servers, which creates management issues.

These traditional connectivity standards face functionality limitations. OPC DA and OPC Unified Architecture (OPC UA) focus on accessing information only from devices — nothing more. Manufacturers wanting to integrate business and enterprise logic must buy an OPC-compatible application or create one with custom code. Custom coding is time-consuming, requiring more than 60% of each project for device and enterprise IT connectivity. Custom coding depends on developers. Manufacturers are vulnerable if the original coder leaves.

Move Ahead with the Telit deviceWISE Advantage

To overcome these limitations, manufacturers need a comprehensive platform to enable device and application communication. Telit deviceWISE is an integrated solution to connect the factory to the enterprise and the value chain fast. This platform empowers them to unlock the data they need to improve productivity and drive growth and revenue.

The platform comes with other open protocol standards, such as Modbus, MT Connect and more. To enable complete and efficient data collection, deviceWISE comes with a growing number of native drivers, including:

  • Siemens
  • Rockwell
  • Omron
  • Mitsubishi
  • FANUC
  • ABB
  • Emerson
  • Schneider
  • Atlas Copco
  • Ingersoll Rand

Real-Time Data Federation

Data extraction and processing and enterprise connectivity capabilities are integrated deep into deviceWISE. While OPC only offers data extraction, deviceWISE can aggregate and transform data into actionable information.

Faster Time to Market

Telit deviceWISE helps manufacturers get the competitive edge they need by accelerating time to market. Factories can deploy the platform without custom code. deviceWISE enables organizations to set up manufacturing environments and pivot when changes are necessary. Deploying and applying alterations to OPC requires custom coding, which slows the process.

Flexible Deployment

Today’s manufacturers can choose from multiple vendors’ various technology solutions. To take advantage of this freedom of choice, they need a platform with total deployment flexibility. Telit deviceWISE is compatible with multiple OSs. It operates on almost any combination of OSs, CPUs, mainframes, servers, and leading switches and routers. While OPC solutions must deploy on a Microsoft OS, deviceWISE enables manufacturers to deploy the optimal solution for their legacy equipment and business requirements.

Out-of-the-Box Enterprise Integration

Integration with existing IT systems is a component of deviceWISE. This integration allows bidirectional communication between systems and machines. These systems include:

  • MES
  • SCADA
  • ERP
  • MRP

A customer can fully integrate OT to IT with deviceWISE in a simple configuration without writing any code. In contrast, the integration available with OPC solutions is limited and demands thousands of hours to create custom code.

Low Latency

Compared to OPC, deviceWISE offers extremely low latency. Benchmark tests show data performance up to 10 times faster than the traditional protocol. With deviceWISE, latency is often near zero, so manufacturers can realize improved efficiency enterprise-wide.

In the world of industrial IoT (IIoT), latency is a critical concern. As more data is produced, the ability to collect and analyze it efficiently impacts machine productivity. If a process demands data validation, each millisecond it takes for the system to respond causes downtime. As a result of OPC replacement by deviceWISE, one carmaker increased uptime by 3,000 minutes per year in one plant. This increase created a return on investment of $90 million per year.

Latency creates unreliable data collection risks. As PLCs are designed to delete their tags each cycle, high latency systems can lose data, compromising data reliability. Telit deviceWISE was built to solve this problem. By enabling features like unsolicited messaging, the system provides near real-time communication, which reduces network data flow and ensures data reliability.

Lab Testing in Stable Environment

Timing data scattered due to:

  • Single-threaded nature of application/ communications
  • PLC creates and destroys OPC tag references every time transaction is called
  • PLC scan time variances
