Protection By Software Security Key - Mitsubishi Electric Q Series Programming Manual

4 AUXILIARY AND APPLIED FUNCTIONS

4.5.2 Protection by software security key

Illegal leak
of project
data
If the software security key set in the project data or operating system software cannot be
imported to MT Developer2, the software security key cannot be released even in repair or
maintenance, and the project data cannot be referred to permanently. Mitsubishi Electric
Corporation cannot be held responsible for any damage which may occur as a result of not being
able to refer to the project data for our customers or other individuals and organizations. Please
be aware of this when using the software security key.
This function is used to protect the user data by setting the software security key to the
project, operating system software, and MT Developer2 to limit the computer which
operates the project and Motion CPU which runs the project.
The software security key is created in MT Developer2 and registered to the operating
system software when the operating system software is installed to Motion CPU. It is
also registered to the user program when the project is created.
The software security key verify is executed between MT Developer2 and Motion CPU
during communication of the computer and Motion CPU. If the keys are not matched,
the communication is not possible.
Only the enabled computer can communicate with Motion CPU. When the user data
are leaked, copying and analyzing the data are prevented.
