7 • SETTING UP COMMUNICATIONS• • • • •4. In RSView Studio , add a data server to the application, that points at the OPC serveryou are using for communications.Details about setting up data servers are provided in this chapter.5. Once an application can communicate with a device, you need to plan how theapplication will access the values in the device. To do this, you can use data servertags, or HMI tags, or a combination of both.For information about when to use HMI tags or data server tags, see Chapter 8,Working with tags.To use HMI tags in the application, open the Tags editor, and then create device tagsthat point at addresses in devices. For details about creating HMI tags, see Chapter 9,Creating HMI tags.6. Create tag connections in the application, wherever you need to obtain values fromtags. For example, to connect an object in a graphic display to a tag, type the tag nameusing the syntax for the OPC server, or use the tag browser to find and select the tag.For details about using the tag browser, see Chapter 8, Working with tags.7 • PlaceholderAdding RSLinx Enterprise data serversYou can add more than one RSLinx Enterprise data server to an RSView distributedapplication. A single area in the application can contain multiple data servers. For eachinstance of RSLinx Enterprise on a computer, you need to create a single data server only.You can only add on RSLinx Enterprise data server to a stand-alone application.
