all three tanks. We need to configure the Application Datasheet as follows (in order to fill in the
field, click on the field and type the data; you can also tab to the next field):
Note: We are only using two lines in the database to configure six tags. Arrays reduce the time
spent configuring the database. Also, arrays allow us to configure functions and scripts that can
optimize the overall application.
We have configured the tags that will receive the state of each valve. Now, we need to configure
the tags that will be used to send commands to the host controller. These tags have the same
number of states and other characteristics of the previously configured tags:
Finally, we need to create tags to store the properties associated with the tanks: temperature, level
and pressure. These attributes are associated with one piece of equipment, a tank. We will use a
tag class to tie all these properties together and associate them to a tank. To create a new class,
select the folder Classes (in the Database tab), right-click it, and select Insert Class.
In the dialog box, type in the new class name, CTank and click the OK button.
In the Application Tags database worksheet, we will reference the properties of the tank by using
tags of Type Class: CTank. Each tank property is defined as a member of the class CTank and each
is defined similarly to a tag with a Type parameter: Boolean, Integer, Real, or String. All of the tank
property class members are analog; so declare them to be real:
