what is the logic control?

Question

i want to know about the question asked and later all these where it work

Answer 1

Logic control is more than simple on or off switching. Classic logic control used to be one or a combination of P, I, D - proportional, integral, differential - meaning that a value was controlled according to its variance from its set point plus its recent movement towards or away from that set point. These days with computing power we have you can apply almost any control alogorithm to adjust, for example, the flow of fuel or water in a pipe to match a whole series of process parameters. Gets a bit complex after that simple introduction.

Answer 2

OK, between "very simple" and "very professional", let me try to find the middle of the road:
Logic control is about making "something happen" based on a set of conditions, using electronic components.
Such conditions can be equals, and, or, not, greater than, less than, after xxx time, and so on. These conditions can be hard-wired (no software necessary) using so-called logic gates. These gates can be made of transistors or relays (even vacuum tubes !! ), but usually integrated circuits are used, offering a wide variety of "ready-made" conditions, which you just arrange to fulfill the complete task.
Nowadays, these individual gates are often replaced by one device called a PIC or Microprocessor, which contains many "general purpose" gates that can be programmed (software needed) to perform specific input conditions.

Answer 3

logic control is to control a device such as a lamp using a logical circuit.
