Function

l Selection of the arithmetic function with the code ARITPH mode.

l The function block limits the result (see table)

ARITPH mode Arithmetic function Limitation

C1010 = 0 OUT = IN1 2

−1

C1010 = 1 OUT = IN1 + IN2 2

−1

C1010 = 2 OUT = IN1 − IN2 2

−1

C1010 = 3 OUT = (IN1 * IN2) / 2

−1 (remainder not considered)

C1010 = 13 OUT = IN1 * IN2 2

C1010 = 14 OUT = IN1 / IN2 2

−1 (remainder not considered)

C1010 = 21 OUT = IN1 + IN2 without with overflow

C1010 = 22 OUT = IN1 − IN2 without with overflow

l The calculation is performed cyclically in the control program.
