The function
device-internal notation and vice versa. See Chapter 16.4.5 "PZD2, Reference Value / Actual Value".
The scaling for In_F_PDP_word1/2 and Out_F_PDPconv_word1/2 is:
Reference Value
+ 100%
- 100%
The possible range = ±200% = +32768 to -32768 = 0x7FFF to 0x8000
This function uses its own reference value
of this function is the usage of the word data type for frequency values, instead of long.
Note: The usage of this function and the usage of In-PZD/Out-PZD objects is shown in the
sample project documented with:
