Password

Functions ► ET/MT-3x6, ET/MT-2x8 ► Falcon-Serie ► Other function ► Text list ► Password

With this function data input or complete pages can be protected against unauthorized access. Use the system menu of the operator interface to choose whether data or pages are to be protected.

SystemMenuPassword

In the system menu the basic functioning is specified and you can select between the options "Refuse page access" and "Refuse variable input". Regardless of the selected option, your choice is valid for the entire project. In principle, pages are always protected. The option selected in the system menu determines whether the access to the entire page is denied in case of a too low access authorization (refuse page access) or data input is not permitted (refuse variable input).

•	Select the levels of access authority in SPSPlusWIN in the "Page properties" dialogue.

•	Specify the requested access authorization and confirm the dialogue by clicking <OK>.

•	Repeat this for every page you wish to protect and for every page which should be write-protected for those with insufficient access authority.

Define access authority for a page:

Dlg_PageAccesLevel

For creating passwords, a text list and an analog variable is required, both with the name "Password". The text list is only recognized automatically as a password list if it carries this name.

Important: Please note that password may only consist of a limited number of characters,

and that every password must end with an exclamation mark "!" and the number of the level.

The level is not related to the order of entry of the passwords.

•	Passwords can be specified on the operator interface.

•	Up to 20 passwords can be administrated.

•	The password length amounts to 8 characters.

•	10 password levels (0-9) can be assigned. Level 9 is the maximum access level and includes the rights of levels 0-8.
