Failed to get a pooled PI connection. Returns to the pool. to return to the pool. Provided PIConnection does not belong to this connection pool. Enumeration that defines the available operations for PI tag removal during metadata synchronization. Do not remove any existing PI tags. This is the default operation. Remove any PI tags where the PI point source matches the setting defined in the PI output adapter and the PI tag no longer exists in the local metadata. The is the recommended option when it is desirable that any locally defined tags that get removed also get removed from PI. This is the least aggressive tag removal synchronization operation. Only PI tags that have a matching point source name will be considered for removal. After point source match, then any PI tags where existing measurement signal ID is not found in any extended descriptors will be removed. Note that removal of any point tags in PI metadata will cause history for removed tags to be inaccessible. Remove any PI tags where existing measurement signal ID is not found in any extended descriptors. Use with caution as metadata in PI will be updated to exactly match local metadata. WARNING: Do not use this option if target PI instance is used for storage of any data other than this local PI adapter. This is the most aggressive tag removal synchronization operation. Any PI tags that do not exist in local metadata will be removed from PI. This option ensures that PI metadata will exactly match local metadata. Note that removal of any point tags in PI metadata will cause history for removed tags to be inaccessible. Exports measurements to PI if the point tag or alternate tag corresponds to a PI point's tag name. Creates a new Returns true to indicate that this is sending measurements to a historian, OSIsoft PI. Returns false to indicate that this will connect synchronously Gets or sets the name of the PI server for the adapter's PI connection. Gets or sets the name of the PI user ID for the adapter's PI connection. Gets or sets the password used for the adapter's PI connection. Gets or sets the timeout interval (in milliseconds) for the adapter's connection Gets or sets whether or not this adapter should automatically manage metadata for PI points. Gets or sets whether or not this adapter should automatically create new tags when managing metadata for PI points. Gets or sets whether or not this adapter should automatically update existing tags when managing metadata for PI points. Gets or sets whether or not this adapter should automatically remove PI tags that no longer exist locally in metadata. Gets or sets flag that determines if tag synchronization should only use alternate tag fields. Gets or sets the number of tag name prefixes, e.g., "SOURCE!", applied by subscriptions to remove from PI tag names. Gets or sets the point source string used when automatically creating new PI points during the metadata update Gets or sets the point class string used when automatically creating new PI points during the metadata update. On the PI server, this class should inherit from classic. Gets or sets flag that determines if defined point compression will be used during archiving. Gets or sets the filename to be used for tag map cache. Gets or sets the maximum time resolution, in seconds, for data points being archived, e.g., a value 1.0 would mean that data would be archived no more than once per second. A zero value indicates that all data should be archived. Returns the detailed status of the data output source. Releases the unmanaged resources used by the object and optionally releases the managed resources. true to release both managed and unmanaged resources; false to release only unmanaged resources. Gets full archive queue status. Returns a brief status of this Maximum number of characters in the status string Status Initializes this . Connects to the configured PI server. Closes this connections to the PI server. Sorts measurements and sends them to the configured PI server in batches Measurements to queue Sends updated metadata to PI. Accesses local output adapter instances (normally only one). Retrieves historical OSI-PI data using AF-SDK. Creates a new instance of the . Gets or sets instance name defined for this . Gets or sets the name of the PI server for the adapter's PI connection. Gets or sets the name of the PI user ID for the adapter's PI connection. Gets or sets the password used for the adapter's PI connection. Gets or sets the timeout interval (in milliseconds) for the adapter's connection Gets or sets the publication interval for this . Gets the start time for reading data. Gets the stop time for reading data. Gets or sets a value that determines whether timestamps are simulated for the purposes of real-time concentration. Gets or sets value paging factor to read more data per page from PI. Gets or sets value that determines if the input data should be replayed repeatedly. Gets or sets the number of tag name prefixes, e.g., "SOURCE!", applied by subscriptions to remove from PI tag names. Gets the flag indicating if this adapter supports temporal processing. Gets or sets the desired processing interval, in milliseconds, for the adapter. With the exception of the values of -1 and 0, this value specifies the desired processing interval for data, i.e., basically a delay, or timer interval, over which to process data. A value of -1 means to use the default processing interval while a value of 0 means to process data as fast as possible. Gets flag that determines if this uses an asynchronous connection. Returns the detailed status of the data input source. Releases the unmanaged resources used by the object and optionally releases the managed resources. true to release both managed and unmanaged resources; false to release only unmanaged resources. Initializes this . HistorianID, Server, Port, Protocol, or InitiateConnection is missing from the . Gets a short one-line status of this . Maximum length of the status message. Text of the status message. Attempts to connect to this . Attempts to disconnect from this . Uses PI event pipes to deliver real-time PI data to GSF host Receives real-time updates from PI Returns false to indicate that this does NOT connect asynchronously Returns false to indicate that this does NOT support temporal processing. Temporal processing is supported in a separate adapter that is not driven by event pipes. Gets or sets the measurements that this has been requested to provide Gets or sets the name of the PI server for the adapter's PI connection. Gets or sets the name of the PI user ID for the adapter's PI connection. Gets or sets the password used for the adapter's PI connection. Gets or sets the timeout interval (in milliseconds) for the adapter's connection Last timestamp received from PI Returns the status of the adapter Releases the unmanaged resources used by the object and optionally releases the managed resources. true to release both managed and unmanaged resources; false to release only unmanaged resources. Reads values from the connection string and prepares this for connecting to PI Connects to the configured PI server. Disconnects from the configured PI server if a connection is open Returns brief status with measurements processed Reads a series of record values from a in time sorted order. Gets or sets the source points that this scanner is reading from. Gets or sets the minimum value of the timestamps of the data points returned by the scanner. Gets or sets the maximum value of the timestamps of the data points returned by the scanner. Gets or sets the handler used to manage any exceptions that may occur while reading data. Reads all instances in time sorted order as a yielding enumerable. Defines a paging factor used to load more data into a page. Each recorded in time-sorted order for the specified and time-range.
