OutputOpt
Code to select one of the five different output options. The Output Option that is
selected will be applied to the data collection for all of the INT8 channels. The
numeric code for each option is listed below with a brief explanation of each. See
the INT8 manual for detailed explanations of each option.
Code Result
0: Average of the event data since the last time that the INT8 was
interrogated by the datalogger. If no edges were detected, 0 will be
returned for frequency and count functions, and 99999 will be returned
for the other functions. The INT8 ceases to capture events during
communications with the logger, thus some edges may be lost.
32768 Continuous averaging, which is utilized when input frequencies have a
slower period than the execution interval of the datalogger. If an edge
was not detected for a channel since the last time that the INT8 was
polled, then the datalogger will not update the input location for that
channel. The INT8 will capture events even during communications
with the datalogger.
nnnn Averages the input values over "nnnn" milliseconds. The datalogger
program is delayed by this instruction while the INT8 captures and
processes the edges for the specified time duration and sends the results
back to the logger. If no edges were detected, 0 will be returned for
frequency and count functions, and 99999 will be returned for the other
functions.
-nnnn Instructs the INT8 to capture all events until "nnnn" edges have
occurred on channel 1, or until the logger addresses the INT8 with the
CaptureTrig argument true, or until 8000 (storage space limitation)
events have been captured. When the CaptureTrig argument is true,
the INT8 will return up to the last nnnn events for each of the
programmed INT8 channels, reset its memory and begin capturing the
next nnnn events. The Dest array must be dimensioned large enough to
receive the captured events.
-9999 Causes the INT8 to perform a self memory test. The signature of the
INT8's PROM is returned to the datalogger.
RESULT CODE DEFINITION
0 Bad ROM
-0 Bad ROM, & bad RAM
positive integer ROM signature, good RAM
negative integer ROM signature, bad RAM
CaptureTrig
Constant,
Variable, or
Expression
This argument is used when the "Capture All Events" output option is used. When
CaptureTrig is true, the INT8 will return the last nnnn events.
Mult, Offset
Constant,
Variable,
Array, or
Expression
A multiplier and offset by which to scale the raw results of the measurement. See
the measurement description for the units of the raw result; a multiplier of one and an
offset of 0 are necessary to output in the raw units.
