Hello biakoup, my device is a modified gateway Profinet RTI. A normal Profinet gateway device transmits 512 bytes of payload to the controller and receives 512 bytes from the controller in a cycle. But, my device expects to send and receive 1024 bytes in each direction in each cycle. If my device in...

Hi biakoup,
thank you for your help!
Can you give me a more specific approach? For example, how can I modify a gateway module and the source code of revpi controller so that it can exchange more than 512 bytes each way (IN/OUT) in each cycle on the ethernet of pibridge between them?

Hello all, I have a question as follows: I want to build a customized module (like gateway modul) and connect to the revpi core/connect via Pibridge. However, the IN/OUT data between my device and the revpi core is 1024 bytes per way instead of 512 bytes payload like a traditional gateway. At this p...

Thank you very much for your answers!

Hi everyone, I'm trying to test the "piTest" program and found a problem with the "piTest -S" (pic 1) command. As the documentation said (pic 2), when stopping the I/O update with the command "piTest -S", the function "piControlStopIO" will be called and all d...

Dear Nicolais,
i think the command "piTest -1 -r RevPiIOCycle" should show the cycle time of I/O data on RS-485 channel, not the cycle time of packets on Ethernet. Or i'm wrong?

Hi all, I connect a gateway module to a RevPi Connect module and watch the data exchange between them via PiBridge's Ethernet channel. In the phase of cyclic data exchange, every approx. 3ms (see picture) a packet is transmitted from the Connect module to the gateway and vise vsa. That means, if I c...

Thank you for your reply! I have already found the answer for my 3.question when i take a look into the source code of RevPi Gate at https://github.com/RevolutionPi/piControl/blob/master/revpi_gate.c and at https://github.com/RevolutionPi/piControl/blob/master/ModGateComMain.h However i still don't ...

Hi community, i'm newbie in area of RevPi module. Please help me to understand following problem. I have a chain of RevPi Master (Connect), I/O module and a RevPi Gateway Profinet IRT an the end of chain. So i unterstool that we can write selected process data of system onto some slots of Gateway. T...

Hi community, i have a project to emulate a Gateway modul, so that the master Connect/Core don't realize it a "fake" Gateway modul and keep the data exchange process with this emulated modul. To do that, i need to know the data exchange protocol between the master modul and Gateway modul. ...
