00:06:00 will cause the block to store data whose timestamp falls in the set: 00:02:59, 00:08:59
… 00:56:59. Note: When Data Time and Data Interval are both 00:00:00, all data coming into
the block is stored for transmission, regardless of timestamp.
Num Values
The SHEF, SHEFFIX, BIN-NONINT, and INSAT formats use Num Values to set the number of
values of this sensor to include in the transmission.
NOTE: Setting Num Values in the Setup tab first will provide the default value used when
adding new SelfTimed blocks to the setup. This can help reduce the number of edits you must
make when creating a setup where the Num Values for each SelfTimed block is the same.
The BIN-INT and ASCII Column formats only uses Num Values entered in the Setup tab. The
value in the SelfTimed block cannot be changed. The NOS format does not use Num Values at
all.
When INSAT is the selected format, then when Num Values is greater than 1, previous data is
placed into the positions of subsequent ids. For example, when sensor id 2 has a Num Values of
3, the most recent value is transmitted as id 2, the next most recent value is transmitted as id 3,
and the next most recent value is transmitted as id 4. Note how this precludes having sensor ids 3
and 4 defined in the setup. If a multiple-position id (e.g., R356) is encountered with Num Values
greater than 1, the values are repeated only within the first frame of the message, and only so
many times as to ensure complete entries (an orphaned integer entry will not occur).
Sequence
Sequence is used by the SHEF, SHEFFIX, BIN-INT, and BIN-NONINT formats to define the
order of the sensors in the message. It is not used by the NOS and INSAT formats as these have
a fixed sequence.
Use Calc Time
The “Use Calc Time” checkbox is used to specify that the input data’s actual time of calculation
should be used for all formatting considerations, and not the data’s scheduled time. This option is
available only when SHEF or SHEFFIX is the current format.
Using the calculated time is useful when the input data is a min or max point from the min-max
block. When this is the case, the data point will be collected regardless of the offset and interval
property values, and will be formatted with its own label, offset, and interval fields, despite the
value of num values. This allows the timestamp of the incoming data to be determined at
runtime, and for it to be formatted with an accurate offset field.
The “Log…” Button
The “Log…” button opens a dialog used to select the backing log containing the data for
transmission.
