Hybrid PLC Mechatronics - Chapter 15 Human Machine Interface

Communications between processor and HMI (human machine interface) is an important subject as well as constructing an operator interface. The chapter includes procedures for attaching computers as HMI devices to the CompactLogix processor from A-B and the Siemens 1200 processor. The basic panels for both manufactures are introduced and explored. Buttons as well as other devices are built. The chapter ends with a discussion of graphics standards and a common problem that I commonly refer as the ‘three-fer’ button. The chapter is a starting point for students needing to learn some graphics before launching their careers. While this chapter begins the broad development of HMI panels, the design of panel interfaces and screen interfaces continue in subsequent chapters, especially the chapter on motion and the chapter on pid control.
