online mode, project engineers can test and monitor communication between devices. From a technical point of view, Simaticimap has the following advantages: • Communication between software components, that is, communication between technical function templates can be defined in Simaticimap through a graphical interconnect. No programming knowledge required. • Consistent data for communication is generated based on engineering information and is downloaded to the device. The communication betwe

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
