1. Introduction to PROFINET and PROFIBUS PROFINET and PROFIBUS are two fieldbuses launched by the PNO organization, first implemented by Siemens. The two are not comparable; PROFINET is based on industrial Ethernet, while PROFIBUS is based on RS485 serial bus. Due to the different media, the protocols of the two are completely different and have … Read more
Siemens Communication 1. Generally speaking, the communication network of an enterprise can be divided into three levels: enterprise level, workshop level, and site level. Enterprise Level: Top-level management of the enterprise; IT technology applications are very extensive, such as the INTERNET. Workshop Level: Solving communication between different process segments that need to coordinate work within … Read more
Industrial automatic control systems integrate information management and automatic control by summarizing, analyzing, and organizing various information collected by industrial control computers from sensors and local area networks, ensuring information security through access authentication. Industrial automation control is mainly divided into three parts: industrial automation systems, hardware, and software. The commonly used industrial automation control … Read more
The common uses of PLCs include replacing relay logic control circuits in electrical control systems. For example, motor control, switchgear automatic transfer between municipal power supply, and control of backup generators, as well as process control DCS systems and building fire protection systems, etc. Generally, the water pressure control in high-rise residential buildings in urban … Read more
