thereby controlling external devices or circuits.
Components of the controller
The controller consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller.
Controllers are divided into combinational logic controllers and microprogram controllers, each with its own strengths and weaknesses. The design of combinational logic controllers is complicated and structurally complex. Once the design is completed, it cannot be modified or expanded, but it is fast. The microprogram controller is easy to design, has a simple structure, and is convenient for modification or expansion. To modify the function of a machine instruction, simply reprogram the corresponding microprogram;
To add a machine instruction, simply add a microprogram to the control memory, but it is done by executing a microprogram. The specific comparison is as follows: a combinational logic controller, also known as a hard wired controller, is composed of logic circuits and relies entirely on hardware to implement the functions of instructions.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5D32123G02 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
