1771-IAD/D PLC Module Description
1. Strong functionality and high cost performance ratio
A small PLC has hundreds or thousands of programming components available for users to use, which have strong functions and can achieve very complex control functions. Compared with relays with the same function, it has a high cost performance ratio. Programmable controllers can achieve decentralized control and centralized management through communication networking.
2. Complete hardware support, convenient for users to use, and strong adaptability
Programmable controller products have been standardized, serialized, and modular, equipped with a variety of hardware devices for users to choose from. Users can flexibly and conveniently configure the system, forming different functions and systems of different scales. The installation and wiring of the programmable controller is also very convenient, usually using wiring terminals to connect external wiring. PLC has strong load capacity and can directly drive general solenoid valves and AC contactors.
3. High reliability and strong anti-interference ability
Traditional relay control systems use a large number of intermediate relays and time relays. Due to poor contact of contacts, faults are prone to occur. PLC uses software to replace a large number of intermediate relays and time relays, leaving only a small amount of hardware related to input and output. Wiring can reduce the control system of mutual relays by 1/10-1/100, greatly reducing the number of faults caused by poor contact of contacts.
PLC adopts 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 or more, and can be directly used in industrial production sites with strong interference. PLC has been recognized as a reliable industrial control equipment by a large number of users.
4. Low workload 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, greatly reducing the workload of control cabinet design, installation, and wiring.
The ladder diagram program of PLC generally adopts a sequential control design method. This programming method is very regular and easy to master. For complex control systems, the design time of ladder diagrams is much shorter than that of relay system circuit diagrams.
The user program of PLC can be simulated and debugged in the laboratory, with input signals simulated using small switches. The status of the output signal can be observed through the LED on the PLC. After completing the installation and wiring of the system, problems discovered during the on-site debugging process can generally be solved by modifying the program, and the debugging time of the system is much shorter than that of the relay system.
5. Simple programming method
Ladder diagram is a programming language commonly used for programmable controllers, with circuit symbols and expressions similar to relay circuit schematics. Ladder diagram language is intuitive, easy to learn, understand, and familiar
Electrical technicians who are familiar with relay circuit diagrams can familiarize themselves with ladder diagram language and use it to develop user programs in just a few days.
Ladder diagram language is actually a high-level language for users. When a programmable controller executes a ladder diagram program, it uses an interpreter to "translate" it into assembly language and then execute it.
6. Low maintenance workload and convenient maintenance
The fault rate of PLC is very low, and it has complete self diagnosis and display functions. When the PLC or external input devices and actuators fail, they can be programmed based on the LED on the PLC
The accommodation provided by the device can quickly identify the cause of the fault, and the method of replacing the module can quickly eliminate the fault.
7. Small size, low energy consumption
For complex control systems, the use of PLC can reduce a large number of intermediate relays and time relays. The volume of a small PLC is equivalent to several relay sizes, so the switchgear can be
The volume has been reduced to 1/2-1/10 of its original size.
The wiring of PLC is much less than that of relay control system, so it can save a lot of wiring and accessories, reduce a lot of installation and wiring time, and reduce a lot of costs.
