Operation The output is the filtered value of input I1. Input I2 is the filtering time.
O = I1 · (1 - e
-t/I2
)
Note: The internal calculation uses 48 bits accuracy to avoid offset errors.
Connections Input I1: 24 bit integer value (23 bits + sign)
Input I2: 24 bit integer value (23 bits + sign). One corresponds to 1 ms.
Output (O): 24 bit integer (23 bits + sign)
MASK-SET Type Logical function
Illustration
Operation The block function sets or resets the bits defined in I2 in I1.
Input I1: Word input
Input I2: Set word input
Input I3: Set/reset I2 in I1.
Connections Input I1: 24 bit integer value (packed boolean)
Input I2: 24 bit integer value (packed boolean)
Input I3: Boolean
Output (O): 24 bit integer value (packed boolean)
MAX
Type Comparative function
Illustration
Operation The output is the highest input value.
O = MAX (I1, I2, I3)
Connections Input I1, I2 and I3: 24 bit integer values (23 bits + sign)
Output (O): 24 bit integer (23 bits + sign)
