Block diagram of programmable logic controller (PLC
The block diagram of programming logic controller (PLC) is shown in above figure. The PLC has following basic sections are, Processor section (CPU) The processor section is brain of PLC which consists of RAM, ROM, logic solver and user memory.[PDF]
EXAMPLE PROBLEMS AND SOLUTIONS
EXAMPLE PROBLEMS AND SOLUTIONS A-3-1. Simplify the block diagram shown in Figure 3-42. Solution. First, move the branch point of the path involving HI outside the loop involving H,, as shown in Figure 3-43(a). Then eliminating two loops results in Figure 3-43(b). Combining two blocks into one gives Figure 3-33(c). A-3-2.[PDF]
On Teaching the Simplification of Block Diagrams*
sented by block diagrams—a group of properly interconnected blocks, with each interconnected block representing and describing a portion of the system [1–4]. In control engineering, the block diagram is a primary tool that together with transfer functions can be used to describe cause-and-effect relationships throughout a dynamic system.
