Creating EPICS Client I/O Servers Interactively

Complete the following steps to create an EPICS Client I/O server interactively.
  1. In the Project Explorer window, right-click a target, such as the My Computer target, and select New»I/O Server from the shortcut menu.
  2. In the Create New I/O Server dialog box, select EPICS Client and click the Continue button.
  3. In the Configure EPICS Client I/O Server dialog box, click the Add Record button to add a process variable you want to monitor. The Configure EPICS Client I/O Server dialog box organizes process variables first by record and then by field.
    Note The manufacturer recommends limiting the number of process variables in one EPICS Client I/O server to 2,000. Create multiple EPICS Client I/O servers if you want to monitor more than 2,000 process variables.
  4. Optional: You also can click the Import File button to load multiple process variables stored in a .db, or record instance, file.
    You typically create a .db file when you configure an IOC.
    Note When you import multiple process variables, LabVIEW imports only the VAL field of the process variables.
  5. Specify the Name of the record of the process variable you want to monitor.
    Record names within the same I/O server must be unique.
  6. Select the field of the process variable and specify the Name, Data type, and Access type of the field.
    Field names under the same record must be unique.
  7. Click the Add Field button if you want to add another field under an existing record.
  8. Repeat steps 3 through 6 for as many process variables as you want to monitor.
  9. Click the OK button.

After you create an EPICS Client I/O server, you can use the View I/O Items dialog box to view the process variables the I/O server monitors. To display the View I/O Items dialog box, right-click the I/O server in the Project Explorer window and select View I/O Items from the shortcut menu.
