5.3.10 LOG Request Logs from Receiver
Many different types of data can be logged using several different methods of triggering the log events. See
Chapter 6, Data Logs starting on Page 70 for further information and a complete list of data log structures.
The hold parameter, which is only valid when the ONTIME trigger is being used, will prevent a log from being
removed when the UNLOGALL command is issued. To remove a log which was invoked using the hold
parameter requires the specific use of the UNLOG command.
The period and offset parameters are only valid when the ONTIME trigger is being used as well. For example,
to log data at 1 second after every minute you would set the period to 60 and the offset to 1.
Maximum flexibility for logging data is provided to you by these logs. You are cautioned, however, to
recognize that each log requested requires additional CPU time and memory buffer space. Too many logs
may result in lost data and degraded CPU performance. Receiver overload can be monitored using the
Buffer Over-run bits of the Receiver Status word in any log header.
