UNION_BACNET_LOG_RECORD_MULTIPLE (UNION)¶

TYPE UNION_BACNET_LOG_RECORD_MULTIPLE : UNION

The Log Multi Record contains either a set of recorded data values or errors related to data-collection, a status change in the Trend Log Multiple object, or an indication that the time and/or date was changed in the device hosting the Trend Log Multiple object.

InOut:

Name	Type	Comment
logStatus	IEC_BACNET_BIT_STRING	This choice represents a change in the status or operation of the Trend Log object. Whenever one of the events represented by the flags listed occurs, a record shall be appended to the buffer. n n LOG_DISABLED:n This flag is changed whenever collection of records by the Trend Log object is enabled or disabled. It shall be TRUE if Enable is FALSE, or the local time is outside the range defined by Start_Time and Stop_Time, or the addition of this record will cause the buffer to be full and Stop_When_Full is TRUE; otherwise it shall be FALSE. n n BUFFER_PURGED:n This flag shall be set to TRUE whenever the buffer is cleared by writing zero to the Record_Count property or by a change to the Log_DeviceObjectProperty property. After this value is recorded in the buffer, the subsequent immediate change to FALSE shall not be recorded. A record indicating the purging of the buffer shall be placed into the buffer even if the Trend Log is disabled or outside of the time range defined by the Start_Time and Stop_Time properties. n n LOG_INTERRUPTED:n This flag indicates that the collection of records by the Trend Log object was interrupted by a power failure, device reset, object reconfiguration or other such disruption, such that samples prior to this record might have been missed.
logData	IEC_BACNET_LOG_RECORD_M_DATA	The Log-Buffer contains an data value entry.
timeChange	IEC_BACNET_REAL	This choice represents a change in the clock setting in the device, it records the number of seconds by which the clock changed. If the number is not known, such as when the clock is initialized for the first time, the value recorded shall be zero. This record shall be recorded after changing the local time of the device and the timestamp shall reflect the new local time of the device.
