8.4 Exercise

Exercise: User Login and Access to the Object

In this example, you will add a user to the project and assign a security level. Then, you will configure the accessibility of the control functions in the Xpanel project.

(1) Adding a user

a) Go to [Tools] – [Security] and press the [New User] button to bring up the [Security Properties] window.

Open

b) Set the user ID to ‘A’ and the password to ‘1234’. Set the user’s security level to 8.

Open

c) Press [OK] and you will see the new user added to the list.

(2) Configuring Objects with Security Level

a) Create an analog tag named “RUN” in the database.

b) Select [Draw] – [Dynamic Tag] and add the object to the graphic page. Then assign the ‘RUN’ tag to the object as shown below.

c) Create an object to write the value of the ‘RUN’ tag. Label it with a text object “Level 10” and group the objects. Then set the action as “Write Tag Value” within the ‘Touch’ feature. Enter 10 in the “Value” field.

d) Go to the [Security] tab and set the Security Level to 10.

e) Create another object to write the value of the ‘RUN’ tag. Label it with a text object “Level 5” and group the objects. Then set the action as “Write Tag Value” within the ‘Touch’ feature. Enter 5 in the “Value” field.

f) Go to the [Security] tab and set the Security Level to 5.

g) Create an object as shown below to log on after the project execution.

(3) Checking the Operation

a) Execute the project with Xpanel or run the simulator. Press the ‘LogOn’ object and then press the ‘Level 10’ object. Since the user’s security level is 8, the object cannot be operated. The following message will appear.

b) When you press the ‘Level 5’ object, the value will be written to the tag value object since the user’s security level is higher than level 5.
