Error LED Blinking non stop
Dear all,
I have shared the same issue two days before and @kstoilov have answered it worked
But now again the problems comes into
PM554 ETH PLC was running perfectly and I have inserted one input and one output to the project and after downloading it into the PLC it started blinking the Error LED and no communication is possible with the PLC.
I have tried the same way when it occurred before as resetting the PLC. I have tried but this time no success
I have got no idea why it is behaving like this. Kindly advice me the possible remedies and also why it is happening so that we will try to avoid the situation happening again
Thanks in advance
Regards
Amal

Hi,
Download the attached backup and check the attached image for Modbus testing details.
Check firmware also.
After again same problem is there. Come online by team viewer with your laptop and PLC.
