This is the current LOGO! 8.2. I don't think the LOGO! is defective.

What do you mean by "stop working"?

Is the LOGO! in stop?

Does she no longer switch outputs?

Do you have a multimeter with which you can measure the supply voltage of the LOGO!?

 I meant the PLC doesn't turn on, didn't show anything in the lcd and didn't recognize by the Ethernet connection.Yes it doesn't switch output neither received any actions.I do have multimeter .i measure the inner circuit of the plc and the electricity is passing.

Supply voltage of the LOGO! so is it okay? It must be 24VDC.

The display is dark and does not show anything, not even the date and time?

Have you accidentally connected 230VAC to the LOGO!?

 Yes, i connect the plc to 24 VDC.

Yes , the display doesn't show anything not even the date and time.

No , i only connect it to 24 VDC
