165.4 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 Z165.2– 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 Z165.2– for the results of logic function.
The logic structure is described in chapter ZConfigurable status word– from page 271.
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
15 … 9 Reserved
Index Meaning
0 Bit number and bit logic for status bit 0 of Z165.2–
1 Bit number and bit logic for status bit 1 of Z165.2–
… …
15 Bit number and bit logic for status bit 15 of Z165.2–
Value Meaning
0 Logic function is switched off.
