10.1 Unary Array Instruction (AR1)
Use this instruction to perform one of these opĆ
erations on a single operand:
D calculate the absolute value (ABS)
D perform a logical NOT (NOT)
D calculate the square root (SQRT)
D perform a negate operation (NEG)
D move from a source location to a destinaĆ
tion location (MOVE)
Use this instruction to perform arithmetic or
move operations on:
D simple variables
D a single element of an array
D multiple elements of an array
The In input can be an array variable or a simple variable/constant. You can place the
result in a simple or array variable.
When EN transitions from false to true, the instruction prepares to carry out the function
specified in Operation by latching (buffering) all the parameters. If you have
programmed the array instruction to operate on the array elements over multiple
program scans, the first scan sets up the operation. Then, the operation is performed
over a series of scans until done.
