If there is a difference between the standard defaults and job requirements, the user can easily change the attributes. For example, if the alarm message associated with an analog input point does not match requirements, the user can display the default message and change it to a new message. When the schematic is complete, the user can select menu items to check point count, user addresses, segment details, and extra text assignments. The next step in creating a CARE database is the control strategy. The control strategy provides the controller with the intelligence to handle the system schematic.
Control can depend on analog points, digital points, or software points.
CARE provides a workspace with a sidebar of control icons to choose from and place in the workspace. See the Control Strategy Example for a typical window. The user can name and create custom control strategies, or use existing control strategy icons. To create a control strategy, the user clicks a point in the schematic, then the desired control icon to connect the two. Software draws lines in the control work space to represent control flow.
