The difference between plc control system and relay control system

The main differences between PLC and relay control systems are: Working principle: Relays are based on electromagnetic principles, while PLC uses programmable computer components. Programming: Relays are wired through physical connections, while PLCs use programming software. Flexibility: Relays have poor flexibility, while PLCs have high flexibility and can easily adjust control functions. Cost: The cost of relays is lower, and the cost of PLC is higher. Application areas: Relays are suitable for simple small systems, and PLCs are suitable for complex large systems.

7 ways to write PLC programs

Seven methods are used to write PLC programs: 1. Ladder diagram: easy-to-understand graphical symbols. 2. Instruction list: text-based instructions, providing fine control. 3. Structured text: modular programming and code reuse. 4. Function block diagram: Graphical representation of functions and operations. 5. Sequence function diagram: Use states and transitions to represent program flow. 6. Wiring diagram: graphically connects PLC inputs, outputs and circuits. 7. Assembly language: The underlying direct operation instruction set.

What is the difference between HMI and PLC?

Difference: HMI (Human Machine Interface) is an intelligent operation control and display device; when the screen is touched, the resistance and voltage on the resistor network change and the touch position is calculated by the software. The PLC is a digital computing controller with a microprocessor for automatic control, which can load control instructions into the memory at any time for storage and execution.

what is plc

PLC is the abbreviation of "Programmable Controller" and is a microcomputer mainly used in the field of industrial automatic control. Originally, the programmable controller (Progammadble Controller) was abbreviated as PC, but in order to avoid confusion with the abbreviation PC (Personal Computer), the programmable controller was called PLC.
