Questions and answers of PLC programmable logic controller_G

I believe that you have a basic understanding of the PLC programmable logic controller after read the "Questions and answers of PLC _ GCAN"
Today, we continue to answer questions for everyone:

Q1: Is it really important for 
PLC programmable logic controller to have a CAN interface?
A1: For this question, I have to say although it is not a basic requirement of PLC 
programmable logic controller, but it is also very important. For example, if the PLC programmable logic controller is like a mobile phone, CAN represents a 4G network, and the PLC with CAN interface can be called a smart phone that could use a 4G network. A PLC without CAN interface is equivalent to an old-fashioned 3G mobile phone or even a 2G elder phone. It is hardly to say useless, but the work efficiency of both parties is indeed very different. In nowadays, when large industrial production is popular, which PLC will be chosen by producer, the results are clear at a glance.

Q2: What are the programming languages of PLC programmable logic controller ?
A2: This is a more professional problem, since we have already known from last article that the PLC is editable, and the user can change the relevant functions of the plc programmable logic controller according to the relevant programming software to suit the specific work requirements. In general, there are several types of languages for PLC programming: SFC (Sequence Function Chart), LD (Ladder Diagram), FBD (Function Block), ST (Structured Text), IL (Instruction Table), etc. They can be used alone or indirectly, which is very convenient and can basically meet all the control setup requirements of engineers.

Q3: What are the advantages of Chinese PLC programmable logic controller, are there any specific examples?
A3: We all know that compared with developed countries in the west, chinese labor costs are relatively low, which will be reflected in product prices finally. If the basic functions are completely consistent, the price of plc programmable logic controller products in China is lower than that of foreign products. Moreover, the manufacturer will optimize according to the usage habits of domestic users, which is further convenient for users. Such as GCAN-PLC series from Shenyang Guangcheng Technology, it is a modular and freely expandable PLC module, with powerful computing and processing capabilities, real-time response to signals and control commands. At the same time, its main control module also has 3 fieldbus communication interface, users can use these communication buses to access the corresponding network to communicate with other devices, and easily access them to the communication control network.

Q4: What's the application areas of PLC programmable logic controllers?
PLC programmable logic controller equipment has a wide range of applications, and has been widely used in steel, petroleum, chemical, electric power, building materials, machinery manufacturing, automotive, textile, transportation, environmental protection and cultural entertainment.

Q5: Is there any PLC programmable logic controller device that supports Ethernet, RS485 and CAN bus interface at the same time without expand?

A5: Guangcheng Technology GCAN-PLC series PLC programmable logic controller is a modular and arbitrarily expandable PLC module. The module consists of a programmable main control module (GCAN-PLC-400), several I/O modules and a terminal module. The main control module uses a high-speed CPU with powerful computing and processing capabilities. It has three fieldbus communication interfaces: Ethernet, RS232/485, and CAN. Users can use these communication buses to access the corresponding network to communicate with other devices. It is powerful and cost-effective, and is definitely the best choice for industrial control.
