The PROFIBUS DP (Decentralised Peripherals) communication network offers high-speed communication between systems and decentralized devices. It uses optical fiber or cables based on the RS-485 standard. Nearly 90 percent of the slaves on PROFIBUS networks operate from PROFIBUS DP.

PROFIBUS DP is mainly used to operate various sensors, actuators and other peripherals via a centralized controller. If you would like to know more about the difference between PROFIBUS DP and PA, click here.

If you would like to know about the difference between PROFIBUS and PROFINET, we have an article about that as well.

This protocol uses two core screened cables in a lovely purple. It also has a wide speed range, between 9.6 kilobits per second and 12 megabits per second. If you want, you can choose a speed to give all the devices on the network enough time to talk to each other. Also, unless you use repeaters or hubs, then the RS485 will allow only 126 devices to connect at one time.
