M12 connectors become more reliable, easier to fit and reduce installer injuries

Executive Summary Equipment maintenance personnel are tasked with keeping the production line running at peak performance while minimizing operations costs. This is made more difficult by the need for specialized skill sets to support a wide range of factory devices that use different communications protocols, data formats, and device management tools, etc. Greatly simplifying this task, it is possible to seamlessly 26

In order to achieve callingthe“fourthindu factories need infra systems to use the IT for automated produ Generating a good requirement set requires that we put considerable thought into each requirement to ensure that it meets these standards: 1. It is necessary. Our project cannot achieve success without the requirement. 2. It is verifiable. We must many disparate manufacturing sy with their own management tools, makes maintenance cumbersome time consuming. Solution Beneits Revolutionizing factory equip management in the IoT era, the Adva SUSIAccess remote management sy delivers the following advantages: • Reduced Total Cost of Owner (TCO): Saving time for mainten personnel, centralized remote monit continuously checks factory floor de and sends alerts to their mobile de as needed. Power usage may be low by automatically powering systems o according to a preset schedule. •Improved Production Performance: Machine data aggreg by the SUSIAccess server is proce by big data analytics to uncover wa increase product yields, improve predictive maintenance, and ide manufacturing problems more quickl • Easy Integration: The sol provides a comprehensive, seam device monitoring and control system buffer would require bi-pol Another option is to use isolat on. Given the H frequencies, an audio would be required which is bulky and consume a larg board area.

This means that the (for example, EMI and EMC). Within a larger development effort, those requirements will be flowed down and traceable from a higher-level specification, such as a system or sub- system specification (Figure 1). If there is no higher- level specification, we must engage with stakeholders in the development to establish a clear set of stakeholder requirements and then use those to establish the embedded system requirements.

between manufacturing equipment and the Advantech server-side software. This solution can interoperate with high-level applications such as data analytics and machine learning. This paper details the benefits and the key ingredients of the solution. Key Business Objectives Increase production line performance and reduce operations costs without sacrificing quality. Business Challenge Although large manufacturers have been using statistical process control and statistical data analysis to optimize production for years, the extreme complexity of today’s data provides opportunities to deploy new approaches, infrastructure, and tools. The challenge is figuring out how to cost-effectively unify device management, control, and data analytics. In addition, manufacturers need a real- time device management platform that enables them to address maintenance issues on a timely basis. Today, there are transmit circuitry AC couples ±500-mV HART FSK signals to the 4- to 20-mA loop via C1. These signals are either sinusoidal or trapezoidal waveforms. A good buffer with enough drive strength is required at the HART modem's output as the Rsense represents a low impedance and there may also be significant capacitance on the current loop cabling. When the HART isn't transmitting, the buffer output would present a low impedance to the loop which could compromise the 4- to 20-mA signaling. For this reason the switch, SW1, is used in series with the buffer output to provide a high impedance when not transmitting.

High-Power link factory floor devices and processes using technologies from the Internet of Things (IoT), thus enabling remote equipment monitoring and management from a centralized dashboard. Providing such a solution, the SUSIAccess* remote management system from Advantech* allows maintenance personnel to perform equipment status and maintenance checks from a web browser at any time, from anywhere, and with any connected device. The factory automation solution uses an Intel® processor-based gateway running an Advantech client-side agent to transparently handle protocol and data conversion, and acts as a conduit he advantages over traditional circuits include less bo rd space and lower cost. The highway addressable remote transducer (HART) protocol allows for bi-directional 1.2/2.2-kHz frequency shift keying (FSK) modulated digital communication over traditional analog 4- to 20-mA current loops. This allows for interrogation of the sensor/actuator, and provid s significant advantages during equipment installation, monitoring and maintenance. HART provides benefits to m intenance crews using a portable secondary device to interrogate the sensor/actuator. But to fully realize all the benefits HART can bring, the sensor/act ator must be connect d to a contro system with HART ena led current inputs or outputs. Let's focus on the HART FSK transmit circuitry. Figure 1 shows a traditional approach. Rsense converts the 4- to 20-mA signal to a 1- to 5-V signal to be read by an ADC. The HART FSK T for ngineers never lose sight of the need to deliver projects that hit the quality, schedule and budget targets. You can apply the lessons learned by the community of embedded system developers over the years to ensure that your next embedded system project achieves those goals. Let’s explore some important lessons that have led to best practices for embedded development. THINK SYSTEMATICALLY Systems engineering is a broad discipline covering development of everything from aircraft carriers and satellites, for example, to the embedded systems that enable their performance. We can apply a systems engineering approach to manage the embedded systems engineering life cycle from concept to end-of-life disposal. The first stage in a systems E Adam Taylor, e2v

Manage the IoT on an Energy Budget​part 1

An intelligent gateway powered by the Zynq SoC enhances productivity in a state-of-the-art manufacturing plant. The Industrial Internet of Things- on-Chip engineering S.L. (SoC-e), streamlines productivity and helps companies like Microdeco become more reliably connected and secure. To maximize profitability, factories Intelligent Gateways Make a Factory Smarter The 4- to 20-mA loop can swing betwee 1 and 5 V while SW1 is open. As this change is AC coupled to SW1, the switch could see up to ±4 V at its input. Hence, a bi-polar supply of ±5 V or more would be required for the switch, or alternately an opto-switch could be used. A tri-state buffer is anoth option, though gain this plan defines the engineering life cycle for the system and the design reviews that the development team will perform, along with expected inputs and outputs from those reviews. The plan sets a clear definition for the project management, engineering and customer communities as to the sequence of engineering events and the prerequisites at each stage. In short, it lays out the expectations and deliverables. With a clear understanding of the engineering life cycle, the next step of thinking systematically is to establish the requirements for the embedded system under development. A good requirement set will address three areas. Functional r quirements define how the embedded system performs. Nonfunctional requirements define such aspects as regulatory compliance and reliability. Environmental Armando Astarloa, System-on-Chip engineering S.L 44
