Xylem STORM 3 Basic Programming manual - Manual (Page 36)

Sets a sensor’s function, specified by the Use Function option under the Processing section
of the Storm’s Sensor Setup screen. Setting a sensor’s function will automatically enable
the function for use as well. If an unknown sensor is specified, an N/A is returned. Functions
from SDI-12 or Basic programs are retrieved by specifying the name of the sensor followed
by the parameter’s name surrounded by parentheses.
SETVALUE SENSORFUNCTION “H-377”, “H377C(X)”
SETVALUE SENSORFUNCTION “H-340SDI(Rainfall)”, “0”

COMMANDS AND FUNCTIONS
SENSORFUNCTION
Splits apart a string into an array of strings. The first parameter provides the string to split apart.
The second parameter provides the array which the new substrings will fill. The optional third
parameter provides the delimiters or characters that determine where to split the primary string. If
more than one delimiter is specified, splitting will occur at each character given. For example, if a
comma and hyphen are given “,-”, content will be split on any commas or hyphens found as in the
example below. If no delimiter is specified, whitespace will be used as the delimiter (e.g. spaces
and tabs). The number of strings found is returned.
Returns -1, 0, or 1 indicating the sign (negative, zero, or positive respectively) of the given number.
var = SGN(-32.645) REM sets var to -1
var = SGN(1023.98) REM sets var to 1
SGN (number)
Returns the sine value of the given number.
var = SIN(PI/2) REM sets var to 1
var = SIN(0) REM sets var to 0
SIN ( )
Causes the program to pause execution for the specified number of seconds. A decimal number
may be used to specify more specific and smaller time increments (e.g. milliseconds). SLEEP and
DELAY are identical commands.
SLEEP 2.5 REM pauses the program for 2.5 seconds
DELAY 0.25 REM pauses the program for 0.25 seconds
SLEEP
