  • Components of a Real-time Machine Vision System
    Machine vision processes consist of algorithms that review images and extract information, make required decisions, and run necessary inspections in real-time. Communication among machine vision systems is executed by a discrete I/O signal or data passed over a serial connection to a device
  • Customer Spotlight - Relio TM Public Security Systems
    A manufacturer of security systems for public facilities required a 2U rackmount computer with a large amount of I/O to interface a variety of motors and sensors. The new system based on the Relio platform replaces a PLC and several discrete I/O modules. The design results in more flexible
  • Tales from the Front: Applying Fieldbus at Genzyme, Part 1
    perceive length limit as a problem, though, because most of the valves are clustered in close proximity to one another, especially on skid equipment, so we embraced this bus for most of the discrete I/O requirements. However, the AS-i bus isn t suitable for use in electrically classified process
  • Fieldbus Part 2
    I/O modules that are attached to the AS-i segment in this cabinet enclosure. Transfer panel proximity switches are hardwired from the transfer panel location to these modules. There was a concern about not exceeding the AS-i bus segment length, and so the segment length was minimized by placing
  • Complementary LED Drive
    Light Emitting Diodes, or LED's, are discrete components able to produce light when a current passes through them. Most microcontroller designs use one or more LED's. This application highlights the utility of driving multiple LED's with a minimum number of I/O pins. Typically, each I/O drives
  • Fieldbus Part 2
    Earlier, we mentioned that AS-i wasn t appropriate for IS applications. Therefore, another solution was sought for the discrete devices in the electrically classified space. An IS implementation with FISCO and an IS solution were envisioned for the discrete devices. We tried to keep host
  • Understanding Soft PLC Features and Requirements
    Soft PLC is a software technology designed to turn an embedded computer into a fully functional and programmable logic controller, also known as a PLC. It combines PLCs' discrete, PID and analog I/O control with high performing computer networking, data handling, and computational capabilities
  • Consolidating Frequency Sources Using Oscillators and Clock Generators
    Typical system design initially focuses on microcontroller (MCU), CPU, memory and I/O components and architectures, and later focuses on how to supply the various clocks required in the system. Complicated systems can end up requiring 10 or more clocks. What is the best way to provide all of those
