E.2: 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 MP200 unit state
information at the time of the time stamp. These bits should be masked out, unless
needed.
E.3: MP200 Metering System Logs
The MP200 unit has 6 logs: System Event, Alarm (Limits), 3 Historical, and I/O
Change. Each log is described below.
1.
System Event (0)
: The System Event log is used to store events which happen in,
and to, the MP200 unit. 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 E.5.5 on page E-29.
2.
Alarm Log (1):
The Alarm Log records the states of the 8 Limits programmed in
the MP200 unit.
• 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.
