ab[index]=formula
Array Byte [index]
APPLICATION: Variables
DESCRIPTION: User signed 8-bit variables
EXECUTION: Immediate
CONDITIONAL TO: Index values range 0 to 203
LIMITATIONS:
An expression used as an index within the [] brackets is limited
to no more than one operator (two values).
No Combitronic requests or functions with parenthesis are
supported within the [] brackets.
This data space is shared with Cam motion (MC) if a RAM table
location is selected. However, the aw command must not be
used to access this space during that time.
READ/REPORT: Rab[index]
WRITE: Read/write
LANGUAGE ACCESS: Assignment, formulas and conditional testing
UNITS: Signed 8-bit number
RANGE OF VALUES: -128 to 127
TYPICAL VALUES: -128 to 127
DEFAULT VALUE: 0
FIRMWARE VERSION: 5.x and later
COMBITRONIC: ab[0]:3=34
where ":3" is the motor address — use the actual address or a
variable
DETAILED DESCRIPTION:
The SmartMotor™ has 8, 16 and 32-bit arrays. The 8-bit array takes the form of the variables
ab[index]. These are general-purpose, 8-bit, signed-integer variables that can be reported,
used on either side of an equation, and mixed in an expression with variables other than 8-bit.
Like all user variables, they are always lowercase, and are automatically initialized to zero at
power up or reset.
The syntax of the 8-bit array is ab[index], which stands for "array byte", and accepts an index
value between 0 and 203. This index can be specified explicitly or through another variable.
For example, ab[4] refers to the fifth element in the 8-bit array, while ab[n] refers to an
element of the array where the variable "n" must be between 0 and 203.
The value of any array variable is reported with the R, PRINT() or PRINT1() functions.
