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 ÷ ½ IN2 ½ 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
