TRUE if the log is not configured or if there was a
data reading error. FALSE in all other cases.
The status code. See the Status Codes table.
Same as the seqNo if it is present in the log; or the
sequence number of the oldest record if the
seqNum is within the size of the log preceding the
oldest sequence number. See the Notes section
below.
Real type output of Field #1 data.
Real type output of Field #2 data.
Real type output of Field #3 data.
Real type output of Field #4 data.
Real type output of Field #5 data.
Real type output of Field #6 data.
Real type output of Field #7 data.
Real type output of Field #8 data.
Notes
If an input type for a field is defined as 5 (Days and hundredths of seconds in two 32 bit
unsigned integers) then the field output data (data1 to data8) will contain the number of
whole days since 01/01/97 and the hundredthSeconds output will contain the number of
hundredths of a second since the start of the current day. If there are no type 5 fields defined
the hundredthSeconds output is set to 0.
To get the oldest sequence number in the log, toggle the enable input while the readRecord
input is set to FALSE. The seqNum, error, and status outputs are updated. The remaining
outputs are set to 0.
Status Code
The configuration is valid or data can be read.
The log is not configured.
The requested sequence number was not in the valid range.
