LogObjectsBase (FB) ¶ FUNCTION_BLOCK ABSTRACT LogObjectsBase EXTENDS BACnet.BACnetServerPluginBase Base class for logging objects default implementions (Trend_Log, Trend_Log_Multiple, Event_Log). It tries to provide a feature complete implementation for logging objects with a reasonable simple implementation. Assumptions / provisions of LogObjectBase and derived: A.) All log data are stored in the file system, one file per object. If large data volumes should be used (Buffer_Size) a high performance file system is recommended. B.) no sophisticated Sequence / Total_Record_Count overflow handling needed - they simply overflow / wrap around If those assumptions / provisions are not valid for your use case, a more sophisticated implementation is needed, for example based on database, in-memory-database etc. BACstack log data are delivered as either IEC_BACNET_LOG_RECORD, IEC_BACNET_LOG_RECORD_MULTIPLE, or IEC_BACNET_EVENT_LOG_RECORD packed in a IEC_BACNET_PROPERTY_CONTENTS and are stored binary as is in one file per logging object. Such a log file contains: 1.) file header 2.) 0..numRecords-1 log records A log record in such a file consists of: 1.) log record header sequence : IEC_BACNET_UNSIGNED time stamp : IEC_BACNET_DATE_TIME 2.) log record data as C-structure 3.) actual number of records in file : IEC_BACNET_UNSIGNED Reasons to do so: - SysFile write operations in append mode doesnt allow writing at file pos <> end for some platforms - reading the last record should be efficient (rewind from file end), for example to get last sequence number If the number of records is supposed to be limited practically (Buffer_Size), then purge operations of the data files are needed (to get rid of old records). Those purge operations are done implicitely in the implementation. A purge operation basically copies the records - except the purged record(s) - to a temporary file, deletes the data file, copy/move the data file to the data file. For those purge operations it might be useful to choose a TempPath on a high speed file system (RAM file system). If TempPath <> PersistentPath the temporary file will be copied to the data file and deleted afterwards, otherwise the temporary file will be renamed to the data file. The purge operations involve a significant performance degradation. In general this should not be an issue, because BACnet logging objects are designed to inform a BACnet management device (OWS/AWS) about “log buffer mostly full” via Notification_Threshold and notifications. The BACnet management device should read and clear the log buffer to avoid “log buffer full” situations which will cause loss of logging data anyway.
