  • A simple local area network, COLAN (Control Oriented Local Area Network)

    Creator:
    Zheng, Yuepeng
    Abstract:
    COLAN (Control Oriented Local Area Network ) is a redesign of the Task-Master, a daisy-chain structure distributed control system. COLAN is a simple bus structure communication subnetwork intended for distributed control applications. Low cost and simplicity are two main design criteria. Point-to-point and broadcast communications are possible. A packet switching...

  • Design of COLAN II, a control oriented local area network

    Creator:
    Kao, Shao-kong
    Abstract:
    This paper describes the design and implementation of COLAN II, a control oriented local area network (LAN). COLAN II employs a bus interconnection structure and a token passing method to control the access to the bus. Major emphasis of the work is on the system structure and the software operating...

  • A programmable system scheduler for control oriented local area networks (COLAN)

    Creator:
    Lim, Choo-chiang
    Abstract:
    The Control-Oriented Local Area Network (COLAN) is a distributed control system for a series of networked microcontrollers, which has been under development at Oregon State University since 1986. A reliable master controller, functioning both as a task scheduler and as a network controller, is required to allow users to perform...

  • COLAN III, a control-oriented LAN using CSMA/CD protocol

    Creator:
    Eum, Doo-hun
    Abstract:
    COLAN III is a control oriented LAN designed to achieve reasonable network performance and flexibility at low cost. These objectives are achieved by utilizing inexpensive microcontrollers (8031s) and hardware support. The CSMA/CD network protocol with single bus structure has been employed in COLAN III as an arbitration method to control...

  • The implementation of a control and development program for a local area network (LAN)

    Creator:
    Norton, Peter S.
    Abstract:
    Rapid advances in technology have seen computing move from a large central computer to desktop microcomputers. This advance was also seen in the design of dedicated computers, computers designed to perform a few specialized tasks or duties. These computers, or microcontrollers, are often controlled by a central computer and themselves...

  • COLAN IV, a local area network for communications and control

    Creator:
    Thye, Yong
    Abstract:
    This thesis discusses the design and development of a viable local area network (LAN) which supports both communications and control applications. The emphasis was to develop a practical and cost effective system which offered high performance while utilizing low cost components. System cost was kept low by utilizing a twisted-pair...

  • A text display node for a control oriented local area network

    Creator:
    Ji, De
    Abstract:
    In recent years, integrated circuit technology has spawned the development of many low cost and high performance microprocessors and microcontrollers. With these devices, there is an increasing interest in the implementation of distributed control networks, utilizing microprocessors in the control nodes. In this work, a low-cost liquid crystal display (LCD)...

  • EDLAN, an educational local area network

    Creator:
    Yu, Hua
    Abstract:
    EDLAN is a simple, inexpensive local area network suitable for educational applications. In EDLAN, a number of personal computers are connected through an RS-485 global bus which carries the data transmission among the computers. CSMA/CD protocol is used to control the access of the global bus. The communications are controlled...
