82104 is a kind of control system widely used in the automation and process automation industry. It is mainly used to provide accurate control and timing of process functions and to achieve remote communication and monitoring. In order to achieve the above technical requirements, 82104 control system consists of two parts: the control monitoring system (CMS) and the communication managements system (CMMS).

Control and Monitoring System (CMS) is the core part of the 82104 control system, which is responsible for the collection, analysis, logic processing, control and communication of collected process data. The hardware components of CMS include control processor, analogue modules, digital I/O modules, communication modules and secondary power components. Its working principle is simple. The monitoring sensor or signal starts from the control cabinet or panel collected by the control processor, then analysed, and finally gets the corresponding logic. After the logic judgement by the processor, the control cabinet or panel will send the signal to the corresponding device to control the process. The control processor can save a lot of calculations by programming, thereby achieving the whole process control effect.

Communication Management System (CMMS) is the communication and network management layer of 82104 control system. It is mainly responsible for the communication and sharing of collected data and information. CMMS mainly includes the network management, protocol management, middleware, network communications, communication security and data warehousing, among which network management is the most important function. The working principle of CMMS is the communication protocol based on TCP/IP transport layer protocol. Firstly, the network management department of CMMS uses the gateway to divide the network into different subnets, and then set up the corresponding message routing, so as to ensure the safety of the data transmission. Secondly, the middleware of the system is responsible for the conversion of different communication protocols, thereby expanding the connectivity of the control system to the external world. Finally, the communication security system will then be used to ensure that the communication is secure and that data is not lost during the transmission process.

In conclusion, 82104 control system provides powerful control and communication capabilities, and its application field and working principle are becoming more and more extensive. It is widely used in the automation and process automation industry, such as the PLC detection system, the process control system, intelligent instrumentation system, industrial control system, industrial communication system, embedded control system, etc. With the continuous development of technology, 82104 application field and working principle are also constantly being improved, providing powerful control and communication capabilities for many fields.
