BASIC COMMANDS & FUNCTIONS

Basic 5000 uses a combination of commands and functions to allow more complex operations to

be performed on the System 5000™. Commands and functions can both return values, though

each is done in a different manner. Commands such as INPUT and GETTASK return values to

the variable specified last on the line, after a comma:

GETTASK “Batt”, a$ REM stores the value of the Batt Task in variable a$

Functions, on the other hand, list the variable first, using an equals operator (“=”) to retrieve the

calculated value:

a = DATETIME(TIME) REM stores the current time (HHMMSS) in variable a

Commands and Functions available to the Basic 5000 language are listed alphabetically below.

Used in conjunction with the GETVALUE command, 420MA retrieves the current setting of the

4-20mA current loop and stores the value in the given variable.

Used in conjunction with the SETVALUE command, 420MA specifies the 4-20mA current loop

to be set to the desired number.

Example:

GETVALUE 420MA, var

REM stores the current 4-20mA setting from the

REM

daughterboard

the

var

variable

slot$ = “SLOT2”

GETVALUE 420MA slot$, s$

REM stores the current 4-20mA setting from

REM Slot 2 in the s$ variable

SETVALUE 420MA, 12.5

REM sets the 4-20mA on the daughterboard to 12.5mA

a = 16.0

SETVALUE 420MA SLOT1, a+2

REM sets the 4-20mA on Slot 1 to 18mA (a+2)

420MA

Used in conjunction with the GETPOWER command, 5VREF requests the current state of the

+5V Reference and stores the value in the given variable. A 1 is stored if On, 0 if Off.

Used in conjunction with the SETPOWER command, 5VREF specifies the +5 Volt Reference to

be turned on or off. Numbers greater than zero will turn the +5 Volt Reference On, and numbers

less than or equal to zero will turn the +5 Volt Reference Off.

GETPOWER 5VREF, var

REM stores a 1 if On, 0 if Off for the 5V Reference

REM on the daughterboard in the var variable

GETPOWER 5VREF SLOT1, s$

REM stores a 1 if On, 0 if Off for the 5V Ref.

REM on the Slot 1 5V Ref in the s$ variable

SETPOWER 5VREF, 1

REM turns the +5V Reference on the daughterboard On

slot$ = “SLOT1”

a = 0

SETPOWER 5VREF slot$, a REM turns the +5V Reference on Slot 1 Off
