Sorry, it is difficult to understand your post, so I'm not sure exactly what you're asking. I assume that you're using an online translator. You may have to ask your questions again.
Er 01, as I think you know, means that the camera is not communicating with the lens. Does it do this for both your lenses?
You said the the LCD was black. Is the camera on (does the top LCD work, or can you see the display in the viewfinder)? If so, did you push the "Info" button? If none of the camera turns on it might be something as simple as the battery case is partly open (the camera will not turn on if the battery case isn't closed).
Thank You for your answer. My problem occur just after I pull out USB cable from EOS and persists for a few hours. I mean LCD at the top and in the viewfinder works fine but every buttons exept the Q button, menu and info button turns off LCD screen. Sometimes Er 01 is shown . I mean it doesnt appears constantly inspite of lens contacts are clean.
File transfer goes without problems, remote shooting too and EOS Utillity works fine but after disconecting camera from PC problem occur. I do not know what do I wrong. Is there something wrong with PC, router setings or can it be body or lens failure.
Weird, never heard of that. It certainly isn't normal behavior. If you take the battery out and put it back in I assume it works normal? Are you using Windows, and if so do you use the button to "Safely remove USB" before physically removing it? I never use it myself, but maybe your system requires it.
As far battery is concerned taking it out and puting back does not resolvs problem. Camera starts work properly after few hours.
That makes me think it is a camera issue. There are no normal malfunctions that need to sit for a few hours to fix themselves. Taking a battery out and putting it back in should reset any electrical issues.
