Function

For both arithmetic blocks the following functions can be preselected:

Code Subcode Arithmetic function Example Note

ARIT1: C0338

ARIT2: C0600

0 OUT = IN1 IN2 is not processed

1 OUT = IN1 + IN2 100% = 50% + 50%

2 OUT = IN1 − IN2 50% = 100% − 50%

3 OUT = IN1 × IN2 100% = 100% ×100%

4 OUT = IN1 ÷  IN2  1% = 100% ÷100%

5 OUT = IN1 ÷ (100% − IN2) 200% = 100% ÷ (100% − 50%)

15 OUT = IN1 % IN2

% here means "modulo"

 20% = 200% [%] 60%

 40% = 160% [%] 60%

 0 = 180% [%] 60%

Remainder calculation:

OUT = IN1 − (n × IN2)

n = integer component of the

quotient IN1 ÷ IN2
