Functional features of PLC (1)

1. Easy to use and easy to program

Because of the simple programming language such as ladder diagram, logic diagram or statement table, without computer knowledge, the system development cycle is short and the field debugging is easy. In addition, the program can be modified online to change the control scheme without removing the hardware.

2. Strong function, high performance price ratio

There are hundreds of programming elements in a small PLC that can be used by users. It has strong functions and can realize very complex control functions. Compared with the relay system with the same function, it has a high performance price ratio. PLC can realize decentralized control and centralized management through communication network.

3. Complete hardware, convenient for users, strong adaptability, PLC products have been standardized, serialized, modular, equipped with a variety of hardware devices for users to choose, users can flexibly and conveniently configure the system to form different functions, different scales of the system. PLC installation and wiring is also very convenient, the general use of terminal connection external wiring. PLC has strong load capacity, can directly drive general solenoid valve and small AC contactor.

After the hardware configuration is determined, the user program can be modified to quickly adapt to the change of process conditions.
