To function, the applications made with Super-Flash do not need special protection keys. One can also say in another way, that the applications made using Super-Flash are not protected: the end user can copy the programs freely and use them again. Unfortunately in the software field the phenomenon of theft, or copying, and often even reselling is very widespread. Where this causes serious problems for those making software packages, it causes even more to those supplying a complete plant. Strategic information regarding some specific plant solutions are often concentrated in supervision software for concentrate information. Whereas some years ago the know-how regarding a process control was concentrated in the hardware solutions, nowadays with standardisation of the control CPU (PLC), the know-how ends up to a large extent in the control and management software. Making an illegal copy becomes particularly simple in the case of machine control when the machine manufacturer is not the same as the supplier of the electrical and automation part. Since a machine is much easier to replicate than a plant, the manufacturer (or the End Customer) can copy hardware and software easily to bypass the supplier who has developed the control system. It is therefore important for there to be the possibility, for the programmer who develops applications with Super-Flash, to adequately protect their work. PROTECT is a product specifically studied for protection of applications made using Super-Flash.
