    The Hardware General Introduction to PLCs The Hardware General Introduction to PLCs 2.1.1 History & Development Bedford Associates, founded by Richard Morley introduced the first Programmable Logic Con- troller in 1968. This PLC was known as the Modular Digital Controller from which the MODICON Company derived its name.

  • Page 20: Programming

    Until recently there has been no formal programming standard for PLC’s. The introduction of the IEC 61131-3 Standard in 1998 provides a more formal approach to coding. Mitsubishi Electric has developed a programming package, “GX IEC Developer” (Covered in detail later in this document.).

  • Page 21: What Is A Plc

    The Hardware What is a PLC? What is a PLC? In contrast to conventional controllers with functions determined by their physical wiring the functions of programmable logic controllers or PLCs are defined by a program. PLCs also have to be connected to the outside world with cables, but the contents of their program memory can be changed at any time to adapt their programs to different control tasks.

  • Page 22: How Plcs Process Programs

    Output signals Input process image At the beginning of each program cycle the system polls the signal states of the inputs and stores them in a buffer, creating a “process image” of the inputs. 2 - 4 MITSUBISHI ELECTRIC...
  • Page 23 The Hardware How PLCs Process Programs Program execution After this the program is executed, during which the PLC accesses the stored states of the inputs in the process image. This means that any subsequent changes in the input states will not be registered until the next program cycle! The program is executed from top to bottom, in the order in which the instructions were pro- grammed.

    The MELSEC FX Family MELSEC means MITSUBISHI ELECTRIC SEQUENCER. The compact micro-controllers of the MELSEC FX series provide the foundation for building economical solutions for small to medium-sized control and positioning tasks requiring 10 to 256 integrated inputs and outputs in applications in industry and building services.
