GEIP Undocumented "Security code"

[RussB]

Attached is an undocumented "feature" in GEIP PLC's that allows one to Download and run your logic but as of today there is no way to upload the logic from the processor. This does not use any passwords, just logic.
Be careful there is no back-door or work-around, AFAIK.
There is no guarantee that this will never change, but as of today there are no plans to "fix" it.

Does not work with Proficy ME 6.5 and 310 rx3i...

Thanks for testing it there.
No surprise though as the PAC uses a different control engine that will handle almost anything you can trow at it.
