Profibus-DP is a field bus for fast data exchange/actuators associated with sensors; Communication is established between the main central unit (PLC or PC) and the slave unit, i.e. sensors, actuators, drivers, etc. The data exchange is circular; The master reads the input data of the slave and writes the output data of the slave. Bus cycle time shorter than the cycle time central unit;

The baud rate of the Profibus-DP interface card is 9. The baud rate is 6 to 12mbit /s according to the Profibus-DP standard. 3. Will support the financial e quello standard Profibus-DP; All the buses had a large number of attachments, the largest being 125 slaves. The total cycle time depends on the number of connected slaves. The 1.5-Mbit /s baud rate allows polling of eight drives in 6 milliseconds. Physical support for standard Profibus-DP; Max. The number of slaves connected to the bus was 125. Example of a single master Profibus-DP system.

Fieldbus (Fieldbus) is a kind of industrial data bus developed rapidly in recent years, which mainly solves the digital communication between the intelligent instruments, controllers, actuators and other field equipment in the industrial field, and the information transmission problem between these field control equipment and advanced control system. Because fieldbus has a series of outstanding advantages such as simple, reliable, economical and practical, it has been highly valued by many standard groups and computer manufacturers.

SDK-C0147 12004-101-00 SBS04M17C Fieldbus is a fully digital, bidirectional, multi-station communication system that connects intelligent field equipment and automation systems. Simply put, the fieldbus is to replace the transmission of traditional 4-20mA analog signals and ordinary switching signals with digital communication.
