Default Re: Getting into PLCs

I suspect the one of the password that in configured in the XC3 is to allow the OP series display to be able to access it. Then there will also be a different password for uploading and downloading the "program" to and from the XC3 plc to the pc.
There is also a password on the OP display which is likely to allow parameter changes that the normal machine operator can't change. This likely only applies to the OP plc not the XC3 plc.
