Discussions about industry today often focus on the substantial potential of the Industrial Internet of Things (IIoT). It promises significant productivity gains, operational efficiency, and bottom line revenue increases, but only with a supply chain offering reliability, stability, and longevity. These values will become more important as manufacturers and system integrators adopt more automation, connectivity, and autonomy – with faster design cycles and more competition increasing the pressure to get to market quickly. The interplay between these requirements will define the industrial marketplace and innovation that developers contribute to it.

Connectivity, reliability

Industry 4.0 reveals how IIoT can upgrade the factory floor. With the right functionality, it can make any industrial environment smarter, using connectivity to collect sensor information that turns yesterday’s Big Data into today’s insights.

Industry’s need for efficiency is acute, so connectivity and efficiency are crucial for developers and organizations to consider throughout the design process.

Supply and price stability ensures manufacturers can continue to develop, build, deliver, and maintain their systems for extended periods. This often requires component suppliers to guarantee supply continuity for as long as 15 years, with a commensurate price guarantee for up to 4 years.

Assess technologies for applications

To balance connectivity, efficiency, and reliability, developers must select suitable technology for each application.

Tracking data from an Industrial IoT application in a factory.

Consider ON Semiconductor’s intelligent power module (IPM) family, which uses insulated metal substrate technology (IMST). This technology integrates many active components on a metal substrate for high integration with excellent thermal conductivity.

From IPMs, motor drivers (brushless DC motor, stepper, brushed), load drivers and relay drivers – vast amounts of semiconductor technology – is in industrial robots and other IIoT applications. These are supported by a growing number of optimized metal-oxide semiconductor field-effect transistor (MOSFET) and insulated-gate bipolar transistor (IGBT) drivers, and high-performance optocouplers that enable engineers to develop reliable industrial drive systems that deliver accurate control in applications using any combination of low-voltage motors and high-current loads.

For efficiency and reliability, temperature, motion, ambient light, and image sensors for machine vision must be optimized for electrically noisy conditions. The sensors’ small signals then need to be filtered and amplified before being converted to digital data and passed to a central processor. Coupled with this is circuit protection from electrostatic discharge (ESD) protection diodes.

The control element of industrial automation typically involves power semiconductors manufactured using MOSFETs or IGBTs, and silicon carbide (SiC) transistors. Switching and power semiconductor manufacturers now offer devices that meet power inverter circuits and motor driver requirements. Compliance with international standards is mandatory in several industries, so many manufacturers develop parts that adhere to international quality standards including ISO 90001:2015 and IATF 16949:2016.

Speeding time to market with IIoT

The seemingly opposing demands of developing more complex circuits within smaller time windows and often lower budgets is prolific in IIoT, putting pressure on development teams to bring machinery invented before the Internet age to the cutting edge of future technology.

For engineers to develop and optimize new products, it is essential to give them the tools they need to make that process as simple as possible.

For design teams, interactive block diagrams present engineers with a reference design for specific applications. Each diagram presents a selection of potential solutions for each key functional block in design. Further details for each component can be accessed from the block diagram and added to a custom worksheet to quickly develop design ideas.

When moving to the early evaluation plan, developers can now turn to ON Semiconductor’s Strata Developer Studio cloud-connected platform as a starting point. Software automatically recognizes evaluation boards once connected to a host PC, then retrieves the latest design collateral and auto-configures the evaluation board, letting engineers get up and running quickly. Paired with Avnet’s global expertise, those designs can go from ideas on a napkin to a product ready with design for manufacturability, strong supply chain, and regulatory considerations.

Bring in partners

IIoT will encompass a wide range of technologies, from sensors to the cloud. Robotics and automation are safety-critical applications demanding the best solutions and developers need partners who can provide the parts and the services to move from idea to product and product to market. Avnet and ON Semiconductor have created a product development ecosystem and software platform to shorten design time for developers and speed time to market.

FreeFlight Systems expands ADS-B installation capabilities

FreeFlight Systems’ 1203C SBAS/GNSS sensor is approved for installation with the Honeywell TRA-100B Mode S Transponder for Boeing 717 aircraft. This supplemental type certificate (STC) provides a single solution for B717 aircraft to meet requirements for the June 7, 2020, ADS-B mandate in the European Union. FAA validation is underway to support U.S. compliance.

The sensor is a certified, high-integrity position source. It pairs with certified Mode S Extended Squitter transponders such as the TRA-100B in transport category aircraft to provide a rule-compliant ADS-B Out system.
