Discuss which domestic plc is better

PLC is also called programmable logic controller. It is a control device that can change the control content in real time through programming software. It is widely used in steel, petroleum, chemical, electric power, building materials, machinery manufacturing, automobiles, textiles, transportation, In various industries such as environmental protection and culture and entertainment. PLC can tell from the name that this is an exotic product, and in fact it is true. It has actually evolved in the outside world for a long time, but it has only been introduced to China in recent years. What are the PLC brands that we are most familiar with? Mitsubishi? Siemens? then what? They are basically foreign brands, don't we have it ourselves? Of course there is. However, compared with other people's things, there is still a gap, but it is not so obvious. Today, let's talk about what should be done if domestic PLC is optimistic, hoping to enlighten everyone.
1. First of all, the domestically-made PLC should have more efficient and powerful communication capabilities, and be able to connect to more types of communication buses, such as CAN bus. Compared with the traditional serial bus, the CAN bus has a longer data transmission distance, faster data transmission speed, stronger anti-interference ability, and higher cost performance. Using it for PLC data communication is more efficient. Of course, we are not saying that it is enough to have the CAN bus communication capability. The original serial communication and Ethernet communication can not be lost. It is best to have these communication interfaces, so that the equipment has better project adaptability.
2. Domestic PLC should have better after-sales service. Who are the customers that the domestically produced PLC basically faces? Of course it is a Chinese! Compared with the situation that foreign products are difficult to accurately and effectively after-sales due to space distance and time difference, there is basically no such problem in our country. Even if it is really necessary for engineers to go to the destination, it is easy to fly or take the high-speed rail. There is no need to consider issues such as passports and visas. Under the premise of this advantage, we should do a good job of after-sales work and give users a very good experience. In this case, can the buyer's sense of identity not be high?
3. The domestically produced PLC should be advanced in the direction of scalability. We all know that PLC equipment in the traditional sense is a big whole, and the number of IO interfaces cannot be expanded. This will lead to a problem. If the control project is relatively simple, it is better to use several IOs. , But what if you encounter a very complicated situation? Don't you do it? Moreover, the integrated PLC equipment is bulky, heavy, and inconvenient to carry. If it is bumped, it is really troublesome. The expandable IO PLC is like a building block. It is composed of a main control head and several IO function pieces. It can be disassembled and assembled as needed. It is very convenient and has obvious advantages to carry. . Hearing this, have you moved a little too?
Shenyang Guangcheng Technology Co., Ltd., in order to meet the needs of PLC users, has also introduced a very easy-to-use expandable PLC that can support CAN bus communication, namely the GCAN-PLC series. Shenyang Guangcheng Technology GCAN-PLC series expandable PLC is a bus module controller with integrated PLC function. It has the characteristics of exquisite appearance and high cost performance. It can be used to connect CAN bus systems, Modbus systems and distributed bus terminal modules, and these terminal modules can be expanded in a modular manner.
Shenyang Guangcheng Technology GCAN-PLC series expandable PLC consists of a programmable main control module (GCAN-PLC-400), several GC series IO modules (GC-1008, GC-3804, etc.) and a terminal terminal module. The GCAN-PLC-400 main control module can be connected to all GC series IO modules. The user can choose the expansion IO module according to the actual needs of the site. The number of expansion IO modules can reach 32. The GCAN-PLC-400 main control module supports automatic configuration. Users do not need to set parameters on the PC. The main control module will be automatically configured according to the front and back positions of the terminal modules inserted.
