Bit mode
The bit logic and the bit number of the source parameter are set in this parameter.
This is a RECORD type parameter (array).
165.5
Logic functions
The status bits of
Z
165.2
–
are combined using logic functions via these parameters. Bi-
nary logic functions of adjacent bits of the configured status can be processed.
Refer to the appropriate bit of
Z
165.2
–
for the results of logic function.
The logic structure is described in chapter
Z
Configurable status word
–
from page 301.
The logic function is activated by entering a value between 1 and 6.
Bit No. Meaning
4 … 0 Bit number
7 … 5 Reserved
8 Bit Logic:
0 = positive logic;

selected bit is copied unchanged into the configured status
1 = negative logic;

selected bit is copied inverted into the configured status
