Internal memory programs, logic operations, sequential manipulation, punctuality, counting, arithmetic operations, and other programmable memories are used to manipulate a variety of machinery or production processes with digital or analog inputs/outputs. PLC-related peripherals should be planned according to the functional criteria that are easy to form a whole and easily scalable with industrial control. What is the effect of PLC power module and power supply?
First, the effect of PLC power module
Programmable manipulators come in a variety of configurations, but the general principle of their composition is fundamentally the same, with a microprocessor as the center. It usually consists of a central processing unit (CPU), memory (RAM, ROM), input/output unit (I/O), power supply, and programmer. As the center of the entire PLC, the CPU plays the role of commander-in-chief. CPUs generally consist of control circuits, calculators, and registers, usually encapsulated on integrated circuit chips. The CPU is connected to the memory unit and input/output interface circuitry via the address bus, data bus, and control bus. The CPU functions as follows: read instructions from memory, fulfill instructions, delete instructions, and handle interruptions. Memory (RAM, ROM)
Memory is primarily used to store architecture, user programs, and job data. The memory used to store the architecture software is called architecture memory, the memory used to store application software is called user program memory, and the memory used to store job data is called data storage.
Second, the power supply of the PLC power module
It provides internal operating power for PLC operation, and some can also be considered to provide power to the input signal.
The programmer is the most important peripheral device of the PLC. The programmer is used to input the user program into the PLC memory. You can also use the programmer to check programs, modify programs, and monitor the status of PLC operations. In addition, the PC can be used to adjust the PLC programming by adding the appropriate hardware interfaces and software packages to the PC. Generally, there are high-speed counting modules, position control modules, temperature modules, PID modules, etc., and these modules have their own modules. CPU, the signal can be pre-processed or post-processed to simplify the PLC's CPU to manipulate the amount of messy program manipulation. The types and features of smart modules are also very different. With regard to PLCs with outstanding functions, these modules have a wide range of types and outstanding features.
What is the effect of PLC power module and power supply? PLC communication includes communication between PLCs and communication between PLCs and other intelligent devices. With the development of computer manipulation skills, factory automation networks have been rapidly developed and varied. PLC manufacturers attach great importance to the communication function of PLC and have launched their own network system. The network system of the new product. The PLC has a communication interface, and the communication is very convenient.
