Exercise: Showing string value according to an analog value

Each water tank will display its status with the change of an analog value. Strings may be configured in the ‘String Editor’ window.

※ Please refer to the String Value manual for more information.

a) Create a new analog tag and name it as ‘VALUE’.

b) Go to [Tools] – [String Editor] to configure the contents of the string table. Add the strings in group 0.

When the ‘VALUE’ tag is equal to 0, ‘The water tank is empty.’ will be displayed.
When the ‘VALUE’ tag is equal to 1, ‘The water has been stored in the tank.’ will be displayed.
When the ‘VALUE’ tag is equal to 2, ‘The water tank is full.’ will be displayed.

c) Select [Draw] – [String Value] and enter the tag name ‘VALUE’ in the text field. Specify the string group as 0.

d) Select [Draw] – [Switch/Lamp] to create a word switch. Define the action as ‘Tag operation’ to add 1 value to the ‘VALUE’ tag for every click.

e) Launch the project in the Xpanel or simulator. The strings from the string table change with the value of the tag.

The string will not be displayed when there is no string configured in the value of the analog tag.

The following example displays the data from the string table by using a string tag.

a) Create a string tag ‘STR’ in the database.

b) Go to [Tools] – [String Editor] to configure the string table. Add a string in the first index of group number 1.

c) Go to [Tools] – [Script] and add a new ‘Start Up’ script named: “str_table”. Write the script as shown below.

d) Select [Draw] – [Dynamic Tag] and enter the tag name ‘STR’ in the text field.

e) Launch the project in the Xpanel or simulator. The data from the string table is shown through the string tag value.

Data in the string tag store up to 80 characters. You can set the length of the string under the [Advanced] tab.
