Hello everybody.
I have a problem with refreshing inputs states of an EIP adapter.
My hadrware is L02-EIP module from Coolmay with 32 DI and 32 DO.
I don't have any problems with outputs, they work fine. But the behavior of inputs is strange.
I am a begginer in EIP and maybe I don't undersend the basics and my problem is just trivial. By the start-up of PLC values from inputs are updated only once, and after that states of inputs are frozen, even when I change states of physical inputs, until I stop and start again the PLC. That means, I can see only "screenshot" of module inputs made during the startup. I have tested it on RPI and Windows runtime. I also have looked into communication T-->O telegrams and I could see that the transfered data fits the hardware signals. Does anybody have the solution?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thank you for answer.
It is not that problem. I can see updated values in I/O mapping window, but they are outdated. Codesys tell me that values are updated but they are realy not :(
