SINAMICS: PROFINET-system redundancy
https://support.industry.siemens.com/cs/document/109744811/sinamics%3A-profinet-system-redundancy
The PROFINET system redundancy allows the assembly of system-redundant systems (S2-system redundancy). The purpose of using fault-tolerant automation systems is to limitează production downtimes, regardless of whether the failures are caused by an error/fault or are due to maintenance work.
The SINAMICS S120, G130, G150 and S150 PROFINET control units support PROFINET system redundancy as from FW V4.8.
Precondition for system-redundant systems is a H-system which consists of 2 fault-tolerant controls – master and reserve CPU – which are constantly synchronized.
Restrictions
PROFINET-IRT is not supported
No simultaneous operation of Shared Device and Shared I-Device
Maximum 2 cyclical PROFINET connections
System redundancy only via the onboard interface of SINAMICS PROFINET Control Unit
For the duration of switching from one controller to the other, the setpoints of the last connection remain frozen and valid.
