Function
For both arithmetic blocks the following functions can be selected (example for ARIT1):
l C0338 = 0
– Output = ARIT1-IN1
– ARIT1-IN2 is not processed
l C0338 = 1
– Output = ARIT1-IN1 + ARIT1-IN2
– Example: 100% = 50% + 50%
l C0338 = 2
– Output = ARIT1-IN1 - ARIT1-IN2
– Example: 50% = 100% - 50%
l C0338 = 3
– Output = ARIT1-IN1 * ARIT1-IN2
– Example: 100% = 100% * 100%
