Chapter 15 Password Management and Data Protection<br />

If the data in the PLC is not protected by a PLC password, there will be two boxes used to set a PLC<br />

password in the Password Setting window. If the users want to set a PLC password, they have to<br />

type the same password in the two boxes, and click OK. If the users want to limit the total number of<br />

password guesses that can be made, they can select the Enable Limited Times checkbox, select a<br />

number in the box at the right side of the checkbox, and click OK.<br />

If the data in the PLC is protected by a PLC password, there will be one box used to unlock the PLC<br />

password in the Password Setting window. If the users want to unlock the PLC password, they can<br />

type the correct password in the box, and click OK.<br />

The users can only type English letters, numerical digits, and spaces in the window. A project<br />

password is case-sensitive. Besides, the limit on the number of characters which can be typed<br />

depends on the model selected. The users have to type a project password according to the hint in<br />

the window. After the users set a PLC password, the data in the PLC will be protected by the PLC<br />

password. The window will be closed after the users click Cancel.<br />

15.3.3 Making a Project Password and a PLC Password Become<br />

the Same<br />

<strong>ISPSoft</strong> provides a convenient function for users. During the downloading/uploading of a project,<br />

users can make the project password and the PLC password become the same.<br />

• Downloading a project<br />

If users select the Synchronize Project and PLC Password checkbox in the Transfer Setup<br />

window, the PLC password will become the same as the project password after the project is<br />

downloaded.<br />

If the users do not set a project password, the system will ask the users to set a project password<br />

after the users select the Synchronize Project and PLC Password checkbox in the Transfer<br />

Setup window. Besides, if the users open an old project which is protected by a project password,<br />

the Synchronize Project and PLC Password checkbox in the Transfer Setup window will be<br />

selected.<br />
