Hello,
I used CODESYS Control Win 64 softPLC for my testing on the PROFINET protocol. It is working with the RTC Class 1. When I want to use the RTC CLASS 3 for the IO Update interval settings, it has given error like "[ERROR]The controller does not support". So, any limitation in the CODESYS or I need to do some setting for it?.

Are you using profinet controller or profinet device?

I am using softPLC as my PROFINET Controller (PC) and netX90 as a PROFINET device?.

Hello,
I found the attached information about the PN-Controller which informed that CODESYS is not support the RTC Class 3 (CC-C). However, CIFX does support it but it is required additional hardware to use it.

So, we can't operate RTC CLass 3 using CODESYS SoftPLC. Is my thinking correct?.

I installed the RTE softPLC on my system and configured the required driver setting for the network adapter. However, when I select the RTC Class 3, it is still showing the "Controller does not support the selected RTE class". It is working with RTE Class 1.

I want to check IRT communication with my device. Can someone help?.

Hello,
Can someone give clarification about the IRT Communication using Control RTE softPLC?.

Not possible...at the moment.

@eschwellinger Thank you for the clarification.

I found that currently, it is only possible with the Hilscher CIFX. Can you clarify that if I want to use the Hilscher CIFX, it is required additional hardware to check the IRT communication or I check it like I done it with Control RTE softPLC?.

Hi,
yes sure, that will work, but which slave do you have which supports IRT?
Which device do you want to connect.

Do you want to do motion with this?

@eschwelliner, Thank you so much.

I want to connect Hilscher's netX90 slave with my PC and check IRT communication. So, what should I do?.

Use a Hilscher CIFX Profinetcard on Control RTE

Hello @eschwellinger,
I tried with instead of adding PN controller, added CIFX PN Controller and run the program but somehow it is not working.

Any extra stpes which I needed to do for it?.

Add the hardware to your device and add the CIFX component to the RTE..

Hello @eschwellinger,

Thank you so much for your support...!!
I am little bit confused here. Are you saying that I need additional hardware (Hilscher's CIFX) to perform the IRT test?.

Yes, for Profinet IRT you need to have a CIFX Card in your RTE system.

Thank you for your exceptional support...!!

I do not have the CIFX card hardware. So, not possible for me to test IRT. Hope so, CODESYS will soon release the IRT support in softPLC.
