19.7 Encrypting files
Encrypting may be used to protect any file (part-programs, subroutines, etc.) making it
illegible so it cannot be used by anyone else. An encrypted program cannot be edited at the
program editor or at the PLC and is not displayed during execution. An encrypted file may
be copied, deleted, etc. like any other file.
Encrypting files and the manufacturer's (OEM's) password.
The encrypting algorithm takes into account the OEM password (general access code). If
this password does not exist when trying to encrypt a file, the CNC will show the relevant
warning and will abort the process. If after encrypting a file, the OEM password changes,
the CNC will no longer be able to read the file.
When the CNC executes an encrypted program or subroutine, it checks whether the current
OEM password matches the one used to encrypt the file. If the two passwords do not match,
the CNC will not be able to execute the program or subroutine and will issue the relevant error
message. A file encrypted in a CNC may be executed in another CNC if the OEM passwords
of the two CNC's are the same.
When pressing the "Encrypt file" softkey, the CNC encrypts the file selected with the cursor.
Encrypting maintains the original file and generates a new encrypted file with the same name
but with the extension fcr. If the CNC encrypts the file successfully, it asks the user whether
or not the original file is to be deleted leaving only the encrypted one. This file cannot be
unencrypted at the CNC; therefore, we suggest to save a copy of the original file somewhere
safe.
In the case of a PLC program, there is no need to encrypt the source file because compiling it is enough.
The source file may be deleted.
