Profinet IRT Gateway: Custom Diagnosis Alarms

Hi, is it possible to trigger any kind of customized diagnosis alarm using the Profinet IRT gateway module ? The user manual only states in section 5.4.2 that the gateway sends a pre-defined diagnosis alarm to the controller when the communication is interrupted. Is there any way to define an own al...

Latency/Delay Issues: Profinet IRT Gateway and RevPi Core S

Hi, I am using a RevPi Core S and the Profinet IRT gateway. My setup is as follows (see complete source code below): Profinet IO Controller : Codesys Control Win V3 running on my PC. Increase Output1 (which corresponds to Input__1 of the Profinet IRT gateway) every 1 s. Output2 mirrors Input1. I.e. ...

Re: Profinet Gateway with Codesys IO-Controller: How to Access Acyclic Data (Records)

Dear Ulrich, what is the reason for The inputs/outputs 321-512 of the Profinet gateway cannot be addressed via a connection with an IO controller on this device. ? Shouldn't it be possible to write records using CommFB.WRREC and read records using CommFB.RDREC, see https://help.codesys.com/webapp/ox...

Re: Advantages of using the Profinet IRT Gateway

Dear Giuseppe, Thank you for your reply and the links. I am aware that the latency depends on the customer application, but I am more interested in some minimum latency which can be achieved in a minimal setup. To be more clear with my questions: What is the minimum latency which can be achieved whe...

Re: Profinet IRT Gateway: latency using cycleloop() or mainloop()

Hello Sven, Thank you very much for your reply. I like your idea to measure the latency directly on the RevPi. I just want to get the idea right concerning your statement "It should receive the Profinet packet via its network interface". Right now, the Profinet communication is between my ...

Hi, I am wondering what the merits and demerits of these two setups are: Using a RevPi Connect with Codesys license as Profinet device . No Profinet IRT Gateway. merits: no Gateway needed, no need to transfer data (process image) between RevPi and Gateway (would it be faster/have less latency?). dem...

Profinet IRT Gateway: latency using cycleloop() or mainloop()

Hi, I am using a RevPi Core S and the Profinet IRT gateway. In order to examine latency issues which I am facing, I did the following: In the RevPi, the revpimodio2 cycleloop() is running with a cycletime of 5 ms. As soon as Input__5 is set to 5, I am sending a ping from the RevPi to my PC: self.rpi...
