the load code body contains the welding control code and the welding serial number of the cab, A team responsible for PLC reads the data on the carrier code body and sends it to me through PLC for the coating Central Control Program (CR ), using the welding control code to generate the coating control code according to certain rules, in the process of generating the code, we need to compare the two tables to obtain the data and send the welding serial number to MES, MES quickly returns the corr

controlled by the PLC.In China's mainstream Siemens 300/400 PLC, for example, the first thing the PLC to ensure is the stability of the business, followed by data collection and processing, and PLC in the formation of the network by many conditions constraints.Firstly, when the PLC communicates with IT system through OPC, it is limited by the capacity of transmitting data. The OPC is set to single-sided, a

KOA does not bind any middleware in the kernel method, it simply provides a lightweight and elegant library of functions, making it handy to write WEB applications.

also a pain point for solving practical work and application scenarios. Data Interaction Between Software and Hardware faces a complex field environment: (1) complex and diverse communication protocols. There are standard protocols, such as Modbus, and many protocol formats modified according to the standard protocol, as well as custom protocol formats, which are very different. For a poor software architecture, it is difficult to cope with it. To increase the number of devices or protocols, we
