Basic Commands and Functions

Returns the provided Task’s most recent measured value. If an unknown Task is specied,

the System 5000™ Default Error String (default is -99.99) is returned. If previous a Task/scan

measurement is desired, an additional parameter may be speciﬁed prior to the last variable. A “1”

indicates the most recent scan, “2” indicates the previous scan, “3” indicates three scans prior, etc.

GETTASK “myTask”, var

PRINT var REM prints “0.023”, as myTask currently measures Analog 1

REM Average the last four scans

task$ = “myTask”

FOR i = 1 to 4

GETTASK task$ i, tempVal

avg = avg + tempVal

NEXT i

avg = avg/4

PRINT “myTask avg: “, avg REM prints the average of the last four scans

GETTASK

Returns the provided Task’s most recent measured value timestamp formatted according to the

system setup (default is MM/DD/YYYY HH:MM:SS). If an unknown Task is speciﬁed, the System

5000™ Default Error String (default is -99.99) is returned. If previous a Task/scan measurement

timestamp is desired, an additional parameter may be speciﬁed prior to the last variable. A “1”

indicates the most recent scan timestamp, “2” indicates the previous scan timestamp, “3” indicates

three scans prior timestamp, etc.

GETTASK “myTask”, var

GETTIMESTAMP “myTask”, var_time$

PRINT var_time$, “ “, var REM prints the timestamp and value of myTask

GETTIMESTAMP

Used to request a new measurement from the System 5000™. Available parameters are ACIN

(AC-In), ANALOGX (Analog), DIFFXX (Differential), BATT (Battery), DIGITALX (Digital Port Level),

FREQUENCYX (Frequency), COUNTERX (Event Counter), QUADXX (Quadrature Counter), SDIXX

or SDIXXX, TEMP (Internal Temperature), and 420MA (4-20mA Output). For analog and digital

measurements, X is a number indicating the requested port or channel. An optional SLOTX may

be speciﬁed for option cards (if not, the daughterboard is presumed). For SDI measurements, the

ﬁrst X is the sensor address, the remaining X or XX is the requested parameter number. An optional

string may follow the SDI request specifying a measurement type, which if not speciﬁed, defaults

to “M”. Note that SDI-12 performs caching on measurement commands. Thus if a measurement

has already been requested for that time period, the previous values will be returned (rather than

requesting a new measurement). To force a new measurement, use the CLEARSDI( ) function to

clear the SDI cache. Lastly, a variable (either string or number) must be speciﬁed to store the

result. If an error is encountered the System 5000™ Default Error String (default is -99.99)

is returned.
