How to use derived tags Here’s an example of how a derived tag can be used. Suppose there are five weight sensors on a conveyor belt. The tag database contains one tag for each sensor, so the weight at each point on the conveyor belt is monitored. If the weight at any point is excessive, RSView ® triggers an alarm. However, if no individual sensor detects an excessive weight, but the total of all five sensors is too high, an alarm might be triggered. To handle this case, you could set up a derived tag to sum the weights of all five sensors. Then, if this total, which would be the value of the derived tag, is too high, RSView can trigger an alarm. How to use multiple derived tag components You can create multiple derived tag components. At runtime, up to 20 derived tag components, containing a maximum of 1,000 tags, can run simultaneously. Use multiple derived tag components to group derived tags that need to be evaluated at different rates. Setting up derived tags The steps for setting up derived tags are: 1. Create the derived tags in the Derived Tags editor. 2. Set the maximum update rate for the derived tags component in the Derived Tag Setup dialog box. 3. Save the derived tags component and give it a name. Using the Derived Tags editor Use the Derived Tags editor in RSView Studio to create derived tags. 10–2 RSView Supervisory Edition User’s Guide
To open the Derived Tags editor: 1. In the Application Explorer, open the Logic and Control folder. 2. Right-click the Derived Tags editor and then click New, or drag the Derived Tags editor from the Application explorer to the workspace. IMPORTANT Do not create derived tags that depend on the results of other derived tags. Derived tag processing is not sequential, and therefore, the results of an expression which includes other derived tags might not occur in the desired scan or order of evaluation. It is best to put as much logic in an expression as possible. Creating derived tags 10–3
