You can enter these settings in the ODC Settings dialog or the Settings tab in the Indicators view. For detailed instructions on setting up online data collection, see the APM ODC Guide. Data Sources An ODC data source is a representation of an external data source used to collect data. For example, a data source might be an OLE Process Control (OPC)-compliant process (OPC DA) that collects real-time data. A data source (which can be an OPC HDA-compliant process) can also be a data archiver or database that stores historical condition readings. Data sources reference multiple data tags (data points) collected from an asset. In most cases, the target data source must be connected to your ethernet network so that you can configure a data source in APM and/or for data collection when the ODC service provider is running. Polling Schedules APM ODC service providers monitor readings using defined time schedules. These schedules determine when, and at what frequency, data readings are taken. Data readings are polled values stored in memory for evaluation. Online indicators must also be configured with rules that define when data readings are recorded as indicator readings.
