Function
For both arithmetic blocks the following functions can be preselected:
Code Subcode Arithmetic function Example
ARIT1: C0338
0 OUT = IN1
Note: IN2 will not be processed
1 OUT = IN1 + IN2 100% = 50% + 50%
2 OUT = IN1 − IN2 50% = 100% − 50%
3 OUT [inc] = IN1 [inc] ´IN2 [inc] ¸16384
OUT [%] = IN1 [%] ´ IN2 [%] ¸100
100% = 100% ´100% ¸(100)
4 OUT [inc] = IN1 [inc] ´16384¸100 ¸ ½IN2½[inc]
OUT [%] = IN1 [%] ¸ ½ IN2 ½[%]
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
