I ahve created a custom device (asynchronous) which tries to read values of channels and also write the values of channels.
when I am running my custom device to communicate with PLC , I am not able to see any data transfer between the two.
So for debugging , instead of sending the values coming from the RT FIFO i am sending constant array values to PLC. In this case I am able to get values on PLC side. Which means RT FIFO not giving me channel values to send to PLC.
What could be the reason for such behaviour?
I am running my custom device on windows system only. I dont have RT system.
