I wonder if anybody can help in above subject. I am using 1756-L61 processor in one of our application. By some reason it is loosing the program stored in its compact flash RAM. In this condition if you go online with the processor, it is showing major fault in the processor. I checked in the major fault tab of the controller properties in RSLogix 5K and it is showing code 60 type 1 unrecoverable fault.
If you clear the fault and download the program again, it is working for some days and same fault is happening again.
Amazing thing in this problem is it is happening only at one stage of the machine operation. i.e. certain operation is running and certain parts of the machine is in specific position.
If anybody know about this problem please let me know as early as possible. my email id is vijay.bhardava [at] dunlop.co.za
