Table 58: Index 00 – Parameters
Example:
Data 1 (Byte 4) = 0xA3, Data 2 (Byte 5) = 0x03
l Resulting 16-bit value = 03A3
hex
Meaning: HY, OS, F2, F1 are assigned a constant; I1, I2 are
assigned to a variable such as I7, I8 C2...etc., appears in the
Parameter menu;
The output of the analog value comparator is active for as
long as the comparison (I1
x F1) + OS = (I2 x F2) + HY is
fulfilled.
