Hello, electrical friends! Today, let’s talk about Siemens PLC communication protocols. As a seasoned automation engineer, I understand the importance of communication protocols in industrial automation systems. Just like people need a common language to communicate, different automation devices also require a “common language” to “talk” to each other. So, let’s embark on this exploration … Read more
PROFIBUS is defined by the German national standard DIN19245 and the European standard EN50170. In the industrial field, PROFIBUS has become a universal, open, and distinctly communicative fieldbus standard. PROFIBUS is a fieldbus technology used for data communication and control at the workshop level for factory automation, enabling a communication network from the field device … Read more
5. CAN Communication Protocol CAN stands for Controller Area Network, which was developed by the German company BOSCH, known for its automotive electronic products, and has ultimately become an international standard (ISO11519 and ISO11898). It is one of the most widely used field buses internationally. CAN is a multi-master asynchronous serial communication bus. Due to … Read more
