 Hello,

I am not sure what your contractor is revering too, and why. But I have been working with S5 for the last 40 years and I have never seen a PLC being "damaged" during a upload or download process.

Also, long as you use the correct Software (Step 5..... or alternative) and the correct communication cable there will be no issues.

I had a PLC once, as you call it corrupted, but only because I loaded FB's that where not part of the CPU family and were pointing to incorrect internal RS registers that halted the PLC. But I was able to recover after a complete reset of the CPU.

Regards / m.f.g

hello 

i have such an exprience

once i download a source but cpu weent to stop

for a week i was struggling with it , finally i found that its the problem of my interface cable which i bought that day.

the problem was :the interface cable did not let the whole program to be load and then cpu was on stop. 

i was lucky that i download with the old interface cable .
