XST/C-H11T3A1B1V0N Liquid Level Controller

The XST/C-H1IT3A1B1VON controller is divided into combinational logic controller and microprogram controller, 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 on hardware to implement the functions of instructions.

Power supply 220VAC; External supply of 24VDC; (Powerful function: with AH, AHH, AL alarm output function)

1. Design the instruction system of the machine: specify the types of instructions, the number of instructions, and the format and function of each instruction;

2. Preliminary overall design: such as register settings, bus arrangement, arithmetic unit design, connection relationships between components, etc;

3. Draw an instruction flowchart: indicate at what time and what component each instruction performs what operation;

4. Scheduling operation schedule: that is, decomposing each operation into micro operations according to the instruction flowchart, and listing the micro operations that the machine should perform according to time periods;

5. List expressions for micro operation signals, simplify them, and implement them in circuits.
