From PROFIBUS to PROFINET - Time to change over
From PROFIBUS to PROFINET – the standard with more than
PROFINET nodes worldwide
for future proofing and more flexibility.
Upgrade to a well-proven standardPROFIBUS is the fieldbus for machines and systems that has been established for years. Based on serial bus technology, it revolutionized the automation world in the 1980s and created the basis for decentralized concepts for the first time. In the 90s, Ethernet spread into IT and industry. With the PROFINET standard, Ethernet has been extended by the features for networking in automation and has been used successfully since then. Today, it is impossible to imagine production without both systems. Through additional extensions, PROFINET is now also used in process automation.
PROFINET – the system of the future
PROFINET combines the advantages of both standards: The industrial experiences of PROFIBUS with the openness and the flexible options of Ethernet. The many advantages of implementing automation and drive technology tasks make switching to PROFINET worthwhile in any case: flexible topologies, one cable for all applications, wireless with PROFIsafe and significantly higher system performance thanks to scalable mechanisms speak for themselves.
A simple change that's worth it
Simple, step-by-step migration
With a step-by-step strategy, operational requirements can also be optimally taken into account. For example, machines can be migrated step by step during periods of low production. In the simplest case, a higher-level controller with PROFINET interface replaces the previous controller. Then the GSDML file for the PROFINET devices is updated in the hardware configuration, the header modules of the decentralized peripherals are replaced in the field and the system components are networked with one another via PROFINET cable.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions only form one element of such a concept. For more information about industrial security, please visit.
