Do you have CX Programmer? You'll need to connect with a peripheral cable or serial cable and view the Error Log.

If you cannot communicate via the ETN card then you likely have an I/O fault. You could try power down then reseat all modules including the power supply and terminating end cap.

thank you.
It did not comunicate unless I power down and restart all modules.
After restart it is ok. but after some time same happen again. should I have to replace some hardware?

Hello, check if you load a program in which you overwrite bits in memory area by accident.
