Security Function

1.1 Overview of Security Function

1.1.1 Precautions on Using Security Function

 Security information set for each function can be cleared using the tool software, however,
performing the clearing operation also deletes project data. Fully confirm before determining
the operations of each security function.
 Although the encryption function encrypts programs to make them unreadable, it cannot
protect projects from being read or rewritten. Use the password protection function in
combination as necessary.

1.1.2 Type of Security Functions

 Password function （1）
 This is a function to set a password for project data downloaded to the PLC for preventing
data from being read and written. Using this function prevents unnecessary rewrting or leak
of know-how.
 The password is valid for configuration data, ladder programs and comments.
 Operation memories can be read or written even when a password has been set.
 A project for which a password has been set is saved as a password-protected file even
when it is saved on a PC. (Available in FPWIN GR7 Ver.1.3 or later)
