Abstract
A technique for saving data related to given machine events in a control that normally records machine events or faults in a first-in, first-out buffer of finite size called an occurrence log by selectively setting the control to respond to the occurrence of a given machine fault or event, monitoring the operation of the machine for the occurrence of the given machine event, and initiating the transfer of the data in the buffer to a nonvolatile memory. Also included is the technique of delaying the transfer of the data in the buffer memory to the non-volatile memory until the recording of a given set number of events is determined in the buffer.
