GX IEC Dev. V5 & Q cpu - keyword protect

3 posts in this topic

Hi all, Is this a flaw??? Have set a cpu keyword in GX IEC and it works, if I try to upload or download MELSEC only then I'm asked for the password, however, if I try to upload out of the PLC SYMBOLIC then it never asks me for the password........and as a result the user gets the entire source code......ok except the 'comments' I thought the whole point of the keyword protection was to protect the PLC code? This means our competitors can go out to our system, connect their laptop and steal our code!.....the whole lot bar the comments within the ladder. Any ideas? I just want to make our code within the PLC as secure as possible. Ian.

Update, Think it works now......looks like have to format all drives, PLC clear, pull battery etc and start from absolute blank and then it seems ok. Phew! Ian.
