PLC Functional Features
1. Easy To use and simple to program
Programming languages such as concise ladder diagrams, logic diagrams or statement tables are used, without the need for computer knowledge, so the system development cycle is short and on-site debugging is easy. In addition, the program can be modified online to change the control scheme without disassembling the hardware.
2. Strong function and high advantage competitive
A small PLC with hundreds or thousands of user-avaiable programming elements is highly powerful and can implement very complex control functions. It has a high performance cost ratio compared to relay systems with the same function. PLC can realize decentralized control and centralized management through communication networking.
3. Complete hardware, easy for users to use
Strong adaptability PLC products have beeen standardized serialized, modular, equipped with a complete variety of hardware devices for users to choose, users can flexibly and conveniently configure the system, composed of different functions, different scale of the system. The installation wiring of the PLC is also very convenient, and the external wiring is generally connected with terminal blocks. PLC has strong load capacity and can directly drive general solenoid valves and small AC contactors. After the hardware configuration is determined, the user program can be modified to easily and quickly adapt to changes in process conditions.
4. High Reliability and strong anti-interference ability
The traditional relay control system uses a large number of intermediate relays, time relays, which are prone to failure due to poor contact of the contacts. PLC replaces a large number of intermediate relays and time relays with software, leaving only a small number of hardware components related to input and output, wiring can be reduced to 1/10-1/100 of the relay control system, and the failure caused by poor contact contact is greatly reduced.
PLC has adopted a series of hardware and software anti-interference measures, with strong anti-interference ability, the average time between failures reaches tens of thousands of hours, can be directly used in industrial production sites with strong interference, plc has beeen recognized by the majority of users as one of the most reliable industrial control equipment.
5. Less work in system design, installation and debugging
PLC replaces a large number of intermediate relays, time relays, counters and other devices in the relay control system with software functions, so that the design, installation and wiring workload of the control cabinet are greatly reduced. The ladder diagram program of plc is generally designed using the sequence control design method. This programming method is regular and easy to master. For complex control systems, it takes much less time to design a ladder diagram than to design a circuit diagram of a relay system with the same function. The user program of the PLC can be simulated in the laboratory, the input signal is simulated with a small switch, and the state of the output signal can be observed by the light-emitting diode on the PLC. After completing the installation and wiring of the system, the problems found in the field coordination process can generally be solved by modifying the program, and the commissioning time of the system is much less than that of the relay system.
6. Small maintenance workload and convenient maintenance
The failure rate of plc is very low, and it has perfect self-diagnosis and display functions. When the plc or external input device and actuator fail, the cuase of the fault can be quickly identified according to the information provided by the light-emitting diode or programmer on the PLC, and the cause can be quickly eliminated by replacing the module.

PLC Controller Integrated systems
In the manufacturing industry, there is a large number of switching-based open-loop sequential control, which performs sequential action numbers according to logical conditions; In addition, there is the control of chain protection actions according to logical relationships that have nothing to do with sequence and timing; As well as a large number of switching, pulse, timing, counter, analog over-limit alarm and other state quantity-based discrete data acquisition and monitoring. Due to these control and monitoring requirements, PLC has developed into a product that replaces relay lines and performs sequence control.
PLC manufacturers & PLC controller suppliers have gradually added various communication interfaces to the original CPU template, and fieldbus technology and Ethernet technology have also developed simultaneously, making the application range of PLC more and more extensive. PLC has the advantages of stability and reliability, cheap price, complete functions, flexible and convenient application, convenient operation and maintenance, which is the fundamental reason why it can occupy the market for a long time.
The hardware of the plc controller itself adopts a building block structure, with montherboard, digital I/O template, analog I/O template, as well as special positioning template, barcode recognition template and other modules, and users can use the method of expanding on the montherboard or using bus technology to equipremote i/o slaves to get the desired number of I/O according to their needs.
PLC Controller in the realization of various number of I/O control at the same time, but also has the ability to output analog voltage and digital pulse, so that it can control a variety of servo motors, stepper motors, frequency conversion motors, etc, that can receive these signals, plus touch screen man-machine interface support, Mochuan MV3U series PLC can meet your needs at any level in process control.
