Scan Interval
Scan Interval formats have the following ASCII format:
hh:mm:ss.t
An example:
01:02:03.5
= Scan interval of 1 hour, 2 minutes and 3.5 seconds
Binary Data Format
Only High/Low/Last (HLL) register and acquisition output data, may be in binary format. Binary formatted data
can be output in either highbyte/lowbyte or lowbyte/highbyte format.
Time/Date Stamp
If binary format is selected, the High/Low/Last register values will also include time/date stamps. When
outputting the High/Low/Last registers for either highbyte/lowbyte or lowbyte/highbyte, the time/date stamp will
have the following format:
can be output in either highbyte/lowbyte or lowbyte/highbyte format.
Time/Date Stamp
If binary format is selected, the High/Low/Last register values will also include time/date stamps. When
outputting the High/Low/Last registers for either highbyte/lowbyte or lowbyte/highbyte, the time/date stamp will
have the following format:
hmstMDY
where each letter is a byte represented as follows:
h
hours
M
months
m
minutes
D
days
s
seconds
Y
years
t
tenths
A typical High/Low/Last will have the following binary format (each letter is a byte of data):
HHhmstMDYLLhmstMDYll
where:
HH
is high,
LL
is low, and
ll
is last
Counts Data Format
The Counts data format is a format that is characterized by an ASCII integer number from -32676 to +32676
that represents a compensated or raw value as it would be interpreted from the A/D converter. This value would
be dependent upon the channel type that has been specified for the channel in question.
that represents a compensated or raw value as it would be interpreted from the A/D converter. This value would
be dependent upon the channel type that has been specified for the channel in question.
Note: The Counts format closely follows the channel type that has been specified.
Example 1.
Example 1.
If channel 16 was type 1: (Type J TC with cold junction compensation and linearization) then the
Counts format output value for this channel would also be cold junction compensated and linearized.
Counts format output value for this channel would also be cold junction compensated and linearized.
Example 2:
If channel 16 was type 31: (Raw A/D data), then the Counts format output value for channel 16 would
also be raw.
also be raw.
Both temperature and volts readings will be represented by a bipolar 16-bit value of the form: +
xxxxx
.
Time/Date stamp format is
hmstMDY
, which is
the same as that specified for the binary data format.
The Counts format is both a valid input (C and L command) format and a valid output format (R, R#, U4, U5,
U8
, U13, C? and L? command queries).
