| PI Interface for Bailey Infi90 61 Chapter 13. Interface Diagnostics Configuration The PI Point Configuration chapter provides information on building PI points for collecting data from the device. This chapter describes the configuration of points related to interface diagnostics. Note: The procedure for configuring interface diagnostics is not specific to this interface. Thus, for simplicity, the instructions and screenshots that follow refer to an interface named ModbusE. Some of the points that follow refer to a performance summary interval. This interval is 8 hours by default. You can change this parameter via the Scan performance summary box in the UniInt – Debug parameter category page Scan Class Performance Points This interface does not support Performance Points. Interface Diagnostics Configuration 62 I/O Rate Point An IO Rate point measures the rate at which the interface writes data to its input tags. The value of an IO Rate point represents a minute average of the total number of values per minute that the interface sends to the PI Server. When the interface starts, it writes 0 to the IO Rate point. After running for ten minutes, the interface writes the IO Rate value. The interface continues to write a value every 10 minutes. When the interface stops, it writes 0. The ICU allows you to create one IO Rate point for each copy of this interface. Select this interface from the Interface drop-down list, click IO Rate in the parameter category pane, and check Enable IORates for this interface. As the preceding picture shows, the ICU suggests an Event Counter number and a Tagname for the IO Rate Point. Click the Save button to save the settings and create the IO Rate point. Click the Apply button to apply the changes to this copy of the interface. You need to restart the interface in order for it to write a value to the newly created IO Rate point. Restart the interface by clicking the Restart button The reason you need to restart the interface is that the PointSource attribute of an IO Rate point is Lab) To confirm that the interface recognizes the IO Rate Point, look in the pipc.log fora message such as PI-ModBus 1> IORATE: tag sy.io.etamp390.ModbusE1 configured.
