When mentioning Siemens’ communication, we must talk about PROFIBUS. Are you familiar with it? PROFIBUS is used in what ways? PROFIBUS supports master-slave mode as well as multi-master and multi-slave operating modes. In a multi-master environment, the control of the bus is determined by a token-passing method among the masters; once control is obtained, the … Read more
Ethernet (Ethernet network) is a network that everyone is very familiar with. It was created by Xerox and jointly developed by Xerox, Intel, and DEC as a baseband local area network specification. It is the most widely used communication protocol standard for existing local area networks today, including standard Ethernet (10Mbit/s), Fast Ethernet (100Mbit/s), and … Read more
PROFIBUS Transmission Technology (Physical Layer) and DP Communication In the ISO/OSI reference model, the first layer defines the “physical” methods of data transmission. This includes encoding types and the transmission standards used (e.g., RS 485). PROFIBUS provides various transmission technologies for the first layer: RS 485, RS 485-IS, MBP, and fiber optic transmission technology. Traditional … Read more
As one of the many members of the fieldbus family, ProfiBus is the most widely used fieldbus standard in the European industrial sector and is also one of the internationally accepted fieldbus standards. ProfiBus is a SIMITAC network belonging to the unit-level and field-level, suitable for transmitting small to medium amounts of data. Its openness … Read more
