PROFINET Overview

PROFINET is an open standard for the realization of Industrial ETHERNET based automation applications. Time-critical and non-time-critical applications could be realized inside the same Network in parallel. Additionally, the network is further on usable for standard office TCP/IP communication.

PROFINET is a cyclic communication. Only for parameterization, diagnosis and alarm-messages of intelligent field devices, acyclic messages will be used.

Note

AC500 PROFINET RT is PROFINET IO based on PROFINETRT.

Standardization: PROFINET

  • IEC 61131-3: PLC Standardization
  • IEC 61158: PROFINET Standardization
  • IEC 11801: Wire and connection elements for ETHERNET

Device Certification

To ensure that PROFINET devices particularly of different vendors can communicate with each other without problems the PNO brought up a certification procedure. In this procedure the conformance in hardware as well as in software matters are tested and documented by an accredited test laboratory. Only certified devices are authorized to bear the name PROFINET.

The certification of the AC500 PROFINET devices took place according to conformance class A and was executed by the accredited laboratory.

Furthermore the AC500 PROFINET devices have CE declaration.
