Is it planned to provide example EDDs, Devkit parts and example Apps in the community stack? The Community Stack is a separate project within PI (PROFINET International). The planning, strategy, implementation and release of the contributions is carried out by the "Community Stack Development ...

Does the Community Stack already have PROFINET Security Class 1 implementation/support? The Community Stack is a separate project within PI (PROFINET International). The planning, strategy, implementation and release of the contributions is carried out by the "Community Stack Development Group...

Is there a limitation of 64 Devices in a PROFINET IRT-network or IRT-domain? Each node/device in PROFINET generates network load. Ethernet has a minimum frame length that is defined as 64 bytes. At a transmission speed of 100Mbit, you can transmit around 64 devices (with minimum frames) per millise...

Is there a way to expand the data frame of 1440 byte? It has been understood for many years that the MTU size of an Ethernet frame is limited to 1500 bytes. Even if so-called jumbo frames are possible with the introduction of Gbit in some networks, these are not used by PROFINET. Jumbo frames are a...

Do we really need managed switches in PN networks? If so, what is the technical reason behind it? First, you don't need a managed switch. This is a question of the maintainability and diagnostics of the overall system as well as the simplicity of troubleshooting during system downtimes. Of course, ...

Is the PN cycle time configured on the device, or can it be adjusted by the PLC and this information is exchanged during start up? The configuration of the devices including the address information (Name of Station, IP), the topological interconnection and the update time are part of the controller...

PROFINET specification talks about PROFINET cycle times below 250 microseconds (DFP etc). Are there currently IO Controllers available (in the market) which support PROFINET cycle times below 250 microseconds? The ASICs ERTEC 200P-2 and ERTEC 200P-3 support the such called IRT performance upgrade. ...

Configuration of TSN networks might be a challenge (depending on the network). How relevant might PROFINET cycle times below 250 microseconds be for the PROFINET market in future (with and without TSN support)? The question is whether cycle times of less than 250µs make sense. As soon as something ...

Hello Community Stack experts. My colleague is trying to build a Linux working PROFINET device application. From there we want to port this Linux version onto other real-time operating systems used by our customers. We are using v00.09.00 of the Profinet Community Stack The makefile is being create...

Hi Sir, Based on the brochure available on the official PI website, the "PROFINET communication stack" is equipped with comprehensive "IO controller" and "Device" functionalities. However, I am seeking guidance or documentation on implementing a controller. Although th...
