What is PROFIBUS?

Field devices PROFIBUS DP

Controller or Control system

Fieldbus-based automation standard

PROFIBUS is the fieldbus-based automation standard of PROFIBUS & PROFINET International (PI), started in Germany in 1986 by an association of 21 companies and institutes. PROFIBUS links controllers or control systems to several decentralized field devices (sensors and actuators) via a single cable.

Communication requirements

Plant-wide communication

Your requirements

Uniform, safe and secure networks without any network transitions

Uniformity and reliability based on accepted standards

Plant-wide, uniform engineering

Access, service and maintenance from anywhere

Detailed diagnostics

Reduced costs for engineering, commissioning and live operation


PROFINET is switched Ethernet

PROFINET basics

Standard Ethernet IEEE802.3

Switching technology IEEE802.1Q

Wireless LAN IEEE 802.11

Bluetooth IEEE 802.15.1

Flexible network topologies

Switch integration into the devices

Physical Port-to-Port communication (Copper 100m, FO up to 80 km)

PROFINET and Standard-Ethernet devices mixed in one network

Reduced network costs

PROFINET is switch integration

PROFINET is "switched Ethernet“ (no need for repeater)

The topology follows the production process Switches connected into a line


PROFINET is Standard Ethernet and more

PROFINET basics

Simultaneous sending/receiving

Usually 100MBit between Controller/Devices

More than 64 kbyte cyclic input and output data per Device possible, typical 20 – 1440 Byte

Acyclic data volume almost unlimited

Logical controller-2-device communication

IT communications parallel to real-time communications

Easy use and integration of standard Ethernet applications

PROFINET uses full duplex communication

More applications on one cable

Separate channels for IO data and TCP/IP

No extra network for TCP/IP needed

The Black Channel Approach

PROFINET

Black channel principle

F-messages between F-host (safety control) and its F-device are transported as payload in PROFINET frames

Guarantees functional safety of the complete path including backplane systems

Additional safety measures of the F-messages

Consecutive numbering of F-messages ("Sign-of-life”)

Time expectation with acknowledgment ('Watchdog")

An identifier between sender and receiver ("F-address")

Data integrity check (“F-CRC = cyclic redundancy check”)

MRP Client

MRP Manager

Media Redundancy Protocol (MRP) Concept

In normal operation the ring topology is reduced to a line

One ring port of the MRP manager is blocked

In case of failure the blocked ring port of the MRP manager change to forwarding

The network reconfigures in short time

The ring topology is reduced to a line again

Automanager for redundant MRP manager

MRP performance

< 200 ms reconfiguration time

Max. 50 nodes in the ring
