HEIDENHAIN TNC 430 PA/M - Addition (+)

7 – 114 HEIDENHAIN Technical Manual TNC 426, TNC 430
7.7.25 ADDITION (+)
Syntax: + (PLUS)
Operands: B, W, D, K
Action:
The TNC extends the operand to the width of the accumulator (32 bits) and
then adds the content of the operand to the content of the word accumulator.
The result of the operation is stored in the word accumulator where you can
process it further.
Example:
Add the constant and the number saved in word W6, then assign the result to
double word D8.
Initial state:
Constant = 10 000 (dec)
Word W6 = 200 (dec)
Double word D8 = ?
To improve clarity, the contents of the accumulator and operand are shown in
decimal notation. The ten-digit accumulator results from the greatest possible
accumulator content (2 147 483 647).
