I am using the ctrlX CORE as a Profinet device, connecting a PLC (Siemens S7-1200) to the Ethernet port XF51. I have managed to get a connection between the two devices, but after a while the connection drops and automatically reconnects.
I will tell you how I have made the connection so that you have more data to be able to make a more exhaustive analysis of what my problem is.
For this, I have added the add-on Profinet Device 188.8.131.52, and as you can see in the following picture I have added the Ethernet device and the Codesys Profinet Device. To the Codesys profinet device, I have added different input and output modules that will be activated or displayed from the external PLC to the ctrlX CORE.
The profinet io task, I have configured it with a priority of 21 and 1ms of scan.
The Profinet communication task I have configured with a priority of 24 and a scan cycle of 10 ms.
As you can see in the following image, I have a connection with the PLC S7-1200 but this connection after a while goes to error and automatically reconnects.
What could be the cause of the connection between the two devices being disconnected?
Thanks and best regards
please increase the watchdog e.g. to 20 for the device at the PROFINET Master. Then it should work with 1ms cycle time at ctrlX CORE too. I don't know how to set it at S7 PN controller, but I added a screenshot of IndraWorks. If there are still some errors you should increase the value once again.
