Hello, I have a problem with a plc x20cp0484-1, I loaded a project and it went perfectly, then after some changes I tried to load what I added and I got an error, after the error I gave a worm restart from automation studio, after power on, no LED came on and I can no longer connect to the plc and the code on it no longer works either.
What if… you try to reset?
And then transfer again?
I can no longer transfer because I can no longer connect to it, I have restarted it several times but it does not reconnect to the ethernet, the LED that indicates the operation of the ethernet remains off
If there is absolutly no LED comming up it might indicate a defect.
If there are some LEDs still active, you sould try to enter the Boot-AR which is possible via the Reset-Button, but with a different pressing order. See this Help-File.
In the Default AR the Ethernet Setting is - Get IP via DHCP and the SNMP function is active, so you should be able to change the IP-Setting via the Online Connection Window in the Automation Studio.
Greetings
Michael
