Discuss pluggable PLC.
What is PLC? It is also called a programmable logic controller, and can generally be connected to at least two communication buses such as Ethernet and serial ports. In addition, it contains numerous IO interfaces, which are used to connect with industrial equipment that needs to be controlled. When we want to control several production machines through the PLC equipment, we send instructions to the PLC through the host computer, of course, the commands must be issued through the communication bus. Then, after receiving the instruction from the communication bus, the PLC device will release the current or voltage information according to the actual situation, and then pass it to the target device through OUTPUT, which is O as mentioned above. The sensor on the target device receives the instruction information, makes the device work, and makes feedback at the same time. This feedback information will be returned to the PLC device through another INPUT line, and finally displayed to the upper computer through the communication bus. This is a cyclic control motion process. Of course, automated production is generally used now, so what is automation? If you start the machine, you don't need to worry about it, it will do everything by itself. In order to enable many different types of production equipment to coordinate actions, it is really appropriate for PLC equipment to uniformly manage and control them.
The traditional PLC equipment is generally a whole, basically the functions have been written and fixed, lack of flexibility. Some friends may only buy half of the functions of a certain PLC device and the other half do not need it at all, but they have to bear the corresponding price. So, can we do a customized service, and what functions do you need for other customers? Because of this requirement, a plug-in PLC capable of inserting a functional module came into being.
This insert on the insert PLC is a function slice. These inserts are distributed with a different number of IO interfaces, which can realize the control connection for the target device. Some of these inserts support voltage transfer information, some support current transfer information, some are digital, and some are analog. You can insert whichever you need, and replace them if you don't need them. It is very convenient. In addition, in addition to the traditional serial interface and Ethernet interface, the main control module of this kind of plug-in PLC equipment can also be connected to the CAN bus interface. The CAN bus has fast data transmission speed, strong anti-interference ability, long data transmission distance, and low maintenance cost, which makes the plug-in PLC have a strong competitiveness. Under the fact that the overall research and development strength of PLC equipment is not as good as that of foreign countries, domestic PLCs should overtake the curve to seize the market of plug-in PLCs and seek corresponding breakthroughs. Among the many types of domestic plug-in PLC devices, Shenyang Guangcheng Technology's GCAN-PLC series plug-in is a PLC that you will undoubtedly not miss, so let's briefly understand it.
Shenyang Guangcheng Technology's pluggable domestic PLC is GCAN-PLC, which is a bus module controller with integrated PLC function. It has the characteristics of exquisite appearance and high cost performance, which can be used to connect CAN bus system, Modbus system and distributed bus terminal modules, and these terminal modules can be expanded in a modular manner. GCAN-PLC pluggable domestic 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. GCAN-PLC type plug-in domestic PLC main control module can be connected to all GC series IO modules. Users can choose to expand IO modules according to the actual needs of the site. The number of extended IO modules can reach 32. GCAN-PLC pluggable domestic PLC main control module supports automatic configuration. Users do not need to set parameters on the PC. The main control module will automatically configure according to the front and rear positions of the inserted terminal module. GCAN-PLC type plug-in domestic PLC can be programmed using OpenPCS software, which supports five standard programming languages in accordance with the IEC-61131-3 standard, which makes the program highly portable and reusable Moreover, the software also has a variety of debugging functions (such as breakpoints, single step, monitoring, etc.), making the debugging program more convenient.
