PROFINET device configurations and topology in TIA PortalTIA Portal – PROFINET PROFINET devices (including networkproducts) are configured using the TIAPortal. These settings are transferred to theSIMATIC CPU and from there to thePROFINET devices. The CPU defines IP addresses and PNnames according to the topology madein the TIA Portal. Also for networkdevices. In the topology, all devices mustsupport the Profinet mechanism.Unrestricted Siemens AG 2018Sivu 8PROFINET TIA in PortalAll parameters relevant to PROFINET are defined in the TIA portaland then transferred to the SIMATIC CPU.

Topology Defined - Automatic Configuration WITH PROFINET YOU ALWAYS HAVE USE MANAGERED SWITCHES! Automatic configuration saves time and minimizes errors With this function, the PROFINET IO controller automatically enters the IP address and devicename of the PROFINET IO devices without a programming device (PG). The requirements for automatic configuration are : The IO controller and IO devices must support the PROFINET function "Device replacementwithout exchangeable medium / PG". In STEP7, you must select the option "Replacing the device without removable media” –”Devicereplacement without exchangeable medium" The devices must be reset to factory settings – factory reset. Profinet GSDxml device description must be found on all devices - includingswitches! The configured topology must correspond to the actual topology!Unrestricted Siemens AG 2018

RT: Media Redundancy Protocol (MRP)1/2MRP is a ring redundancy method used in Profinetapplications. The redundancy manager sends testmessages from each of its ring ports as long as themessages arrive at the other ring port. This way themanager knows that the ring is intact. At the sametime, it prevents messages from circulating indefinitelyin the ring, closing one of the ring ports.Unrestricted Siemens AG 2018

RT: Media Redundancy Protocol (MRP)2/2When test messages no longer arrive at another ringport, such as a damaged cable, the manager opensthe closed ring port. In this case, post-breaksubscribers are available.Network recovery (reconfiguration) takes up to 200 ms(50 subscribers).Unrestricted Siemens AG 2018

IRT: MRPD seamless ring. Max. 32 devicesThe MRPD mechanism is based on IRT and MRP. Areconfiguration time of 0ms is possible by sending cyclic IRTpackets duplicated in both directions on the ring. The recipientreceives the same IRT frame twice if there are no errors on thenetwork.The devices receive this information on both ring ports, so there isno ring remodeling time. As with MRP, redundancy managementprevents loops.Unrestricted Siemens AG 2018
