  • Fully Automated Factories - Futuristic or Today's Reality?

    Fully Automated Factories - Futuristic or Today's Reality?

    Automated factories and processes are too expensive to be rebuilt for every design change – so they have to be highly configurable and flexible. To successfully reconfigure an entire production line or process requires direct access to most of its control elements—switches, valves, motors and drives—down to a fine level of detail.

  • Multi-Segment Ethernet Networks

    The maximum length of a 10BASE5 segment is 500 m and this would represent the network diameter of the Ethernet network if no repeaters were used. However, Ethernet can be expanded to a larger network diameter by using repeaters as long as the network diameter does not exceed the collision domain of Ethernet. This article will discuss those restrictions.
