40.14 Object Flag Actions
WITS incremental record type 1,009 defines DNP3 object flag actions. This functionality is managed by
the DNP Slave application. Each DNP point has a WITS Flag Actions tag, which defines what actions to
take when flags change state.
The use of the WITS Flag Actions tag is not obvious. Although there are eight different actions defined by
this incremental record, all actions are stored within a single tag for each point. The value of the tag has
the following interpretation:
Bits
Description
0-1
Action to be taken on the ONLINE flag changing
2-3
Action to be taken on the RESTART flag changing
4-5
Action to be taken on the COMM_LOST flag changing
6-7
Action to be taken on the REMOTE_FORCED flag changing
8-9
Action to be taken on the LOCAL_FORCED flag changing
10-11
Action to be taken on the CHATTER_FILTER or OVER_RANGE flag changing
12-13
Action to be taken on the DISCONTINUITY or REFERENCE_ERR flag changing
14-15
Reserved for future use
In this manner, the flag action for each flag can be defined to be between 0 and 3. By default, the flag
action for every point is defined as 16,383, which has the binary representation of:
0b0011111111111111
This value has bits 0-13 all set to 1, and bits 14-15 set to 0. The interpretation of this is that a flag action
of 3 is defined for every flag in the list.
40.15 Minimum, Maximum, and Mean
WITS incremental record types 1,010, 1,011, and 1,012 define logging for minimum, maximum, and mean
values of periodic logs. This is all implemented as part of the same functionality as Point Archives.
When a Point Archive is defined, the minimum, maximum, and mean values are automatically calculated
and included in the log file. However, there is another flag entry within the log file which defines what
should be returned when a WITS log file read is performed. For example, this flag entry may define that
the point archive and the maximum should be returned. So even though the minimum and mean would
also have been recorded, these would not be returned in the log file read.
The minimum, maximum, and mean values are stored under the Minimum, Maximum, and Average tags
under each Interval Tag node. If any of these values are assigned to a virtual analogue input, then the
analogue input will have its alias tag point to the relevant Interval Tag value.
40.16 Integral Values
WITS incremental record type 1,013 defines Integral calculations. Integral values are implemented by the
Analogue Watcher application. The configuration for these records is stored under
AnalogWatcher.Integral Values.
