A program I edited a month ago now gives me a flashing "WRITE PROTECT" message when I try to make a change. I am using the correct log-in credentials and sequence for making a change within a program. Is there a parameter that would prevent me from editing programs using the controller?

I have tried to get around this by uploading the program with the revision I made offline, but I can only punch the program onto my flash-drive; I cannot read it back into the controller...I get a flashing "LSK" message...but that is a separate issue.

I have a log in username and password I need to enter before I can make program changes. I also need to use a key to enable program changes to be made.
Someone else is going to check to make sure that the key slot is functioning properly.

Any thoughts?


Thank you!
