Function
For both arithmetic blocks the following functions can be preselected:
Code Subcode Arithmetic function Example
0 OUT = IN1
Note: IN2 will not be processed
1 OUT = IN1 + IN2 100% = 50% + 50%
2 OUT = IN1 - IN2 50% = 100% - 50%
ARIT1: C0338
3 OUT [inc] = IN1 [inc] ×IN2 [inc] ÷16384
OUT [%] = IN1 [%] × IN2 [%] ÷100
100% = 100% ×100% ÷(100)
4 OUT [inc] = IN1 [inc] ×16384÷100 ÷IN2[inc]
OUT [%] = IN1 [%] ÷IN2 [%]
1% = 100% ÷100%
5 OUT [inc] = IN1 [inc] ×16384 ÷ (16384 - IN2 [inc])
OUT [%] = IN1 [%] × 100 ÷ (100 - IN2 [%])
200% = 100% × (100) ÷ (100 - 50%)
Conversion: [inc] = [%] ÷ 100 × 16384
