Designing Device Security Section 6-3
6-3 Designing Device Security
This section describes how to set access restrictions with passwords to pre-
vent improper access to project files created using the G9SP-series Controller
or G9SP Configurator.
Password Types and Application Examples
The following two types of passwords can be used.
Precautions for Correct Use
• For security, we recommend you set a device password and a project file
password.
• There is no way to recover a parameter password if it has been lost, and so
a project file with no set password must be separately saved if a parameter
password is set.
• The parameter password is enabled when the project is downloaded to the
G9SP-series Controller. Always download the project after setting the pass-
word.
• Refer to 8-5 Setting a Device Password for information on measures when
the device password is lost.
Project File Rights
Project file rights are determined by the results of parameter password verifi-
cation. The following describes the file rights.
