Hi
I have an S7 program written by a previous employee. I went to the site and found miscompares of blocks etc.
I obviously wanted to back the program before i did any work.
What is the preferred method of uploading? On other PLC types I simply upload and 'blow over' the existing program where as I had to create a new program and upload on S7, losing all symbols and rung comments. I realise I can copy the symbol file over but lose the rung comments.
Cheers
