Guys:
There is no way to recover the program - I'm sorry.
I've worked with Twidos for a long time and (like Nanos) once you protect the code it stays protected.
If you return the Twido to =SCH= , for a charge, they can erase the memory, but you won't be able to recover the program.
The reason being has to do with the OEM.
If someone was able to unprotected a code on a small PLC, that PLC maker will never be used in an OEM.
They spend ages developing and perfecting a PLC code and are not too keen to see it copied.
With the memory from the PLC, you can get the raw machine code, but you won't get any more than that.
Sorry,
