Hi

the description of the fault you have provided and the type of accessory information you have indicated is absolutely insufficient to try any hypothesis.
How long has your CPU been working properly after first commissioning?
Did you change anything in the network configuration to access the cpu?
Other significant events that may be related to this?

You must try to understand that without a crystal ball, anyone who reads your question will hardly have an valid or useful answer.

3 years it has worked properly after commissioning..
Now we are facing a issue once in a week.
After that we are not changed any settings related to network..

Ok, better but not very well!
I take and copy directly from your starting question:

"If I try to connect the CPU to check the diagnosis then it will not go online.
after the download of the same program it will work for a time .. "

So, it seems that when you try to log in to see the kind of error, you can't connect and go online ... but then how do you download the program?
After loading the program, do you remember to do the "Create Boot Project" operation?
Did you try to turn off and on the PLC after an error event? Does the CPU stay in STOP or can it go to RUN?
Is the PC you connect to looking for the error on the same domain and network as your PLC?
Have you tried when you log in to download your program to check the contents of the error log from Automation Builder?
Try doing the steps I described to you, if you give us more information, maybe we can help you better ...

Dear Mr.Flavio Mussolin
1.As problem appears first we try to communicate to check the logs, but that is not happening because it will shows "online and offline programs are mismatch" error.
2.We tried to turn off and then on it will go run mode.
3.we will not create the boot project operation. Will you please explain us what the "boot project " exactly is?

Hi
A good rule to have the program inside the permanent memory of the cpu, is to use the "create boot project" option after having finished the various optimizations during commissioning. Creating the boot project allows you to safely store the program you want to always load in the cpu, for example after a power outage. Another good rule is to create a clone of the program in the SD card, in order to have it available on other CPUs where the program is the same or for backup.
