n

Variable TIME and Fixed SIZE

This form is used with event-initiated log entries. The first 4 bytes of the
entry is the time that the event occurred. The time bytes come from Register
Address 4 to 7 followed by the log entry (if any). For example, if an event
initiated log entry stored the instantaneous value channel 1, the entry would
be:

time (4 bytes), channel 1 (1 byte)
