  • The Web PLC is here
    Plus, and Ethernet networks. A ladder logic diagram from a PLC can be called up on a browser screen indicating the status of system components such as pilot lights, relay contacts, and motors. Applets can be written to represent the start and stop boxes allowing manual control of stopping
  • Chameleon of control: The ever-changing PLC
    A diversity of applications and technical changes keep PLCs a viable contender in the control arena. The ZEN logic controller from Omron measures 70 X 90 X 56 mm and comes standard with 10 I/O lines. Ladder logic programs can be as large as 96 lines. An existing OEM elevator controller is replaced
  • Ladder Logic Programming
    What makes a PLC special? PLC's are used to automate machinery in assembly lines. For our project, we use the computer link feature that allows a PLC to take commands and communicate with a host computer. If something goes wrong with the computer link, the PLC still functions and protecting
  • Servos Find a Packaging Niche
    on the back of a manufacturing engineer's neck, look first at the old-fashioned drive-shaft packaging lines. They may not be flexible or precise, but their mechanical linkages make them very, very predictable. A PLC using ladder logic engages one function after another. It is a system that is relatively easy
  • Backtalk 12/11/08
    It's been 40 years since the first programmable logic controller (PLC) was conceived during a hangover. These virtual relays in a box let programming take place on or off the factory floor. On Jan. 1, 1968, Dick Morley was supposed to be working on a proposal for another project but he decided
  • When PCs Control Machines
    the need for tracing wires from a programmable logic controller or writing ladder logic. The computer becomes the PLC and does the
