Hi,
I further checked the problem and now it is discovered that the message is appeared due to "Read Protection" implemented using MEMSW $8000 command at startup of the program.
The backup tool worked even if the memory protection is used, thats why i was able to read .cod file. Now the problem is still there how to access PLC using ladder builder. The second option if it is possible to modify .cod file as per requirement and put it back to PLC......?
