B.5.1: Data Formats
Time stamp: Stores a date from 2000 to 2099. Time stamp has a Minimum resolution
of 1 second.
The high bits of each time stamp byte are used as flags to record meter state
information at the time of the time stamp. These bits should be masked out, unless
needed.
B.5.2: Shark® 200 Meter Logs
The Shark® 200 meter has 7 logs: System Event, Alarm (Limits), 3 Historical, I/O
Change, and Waveform. Each log is described below.
1.
System Event (0)
: The System Event log is used to store events which happen in,
and to, the meter. Events include Startup, Reset Commands, Log Retrievals, etc.
The System Event Log Record takes 20 bytes, 14 bytes of which are available when
the log is retrieved.
NOTE:
The complete Systems Events table is shown in Section B.5.5, step 1, on page
B-30.
2.
Alarm Log (1):
The Alarm Log records the states of the 8 Limits programmed in
the meter.
• Whenever a limit goes out (above or below), a record is stored with the value
that caused the limit to go out.
• Whenever a limit returns within limit, a record is stored with the "most out of
limit" value for that limit while it was out of limit.
