Action of the master Slave reaction
Write value in Write_Data (bytes 0-3).
Write function number to
Write_Value_Select.
Read data from Write_Data (bytes
0-3).
Set the Write_Active bit.
Wait until Write_Active has been set.
Write 0 in Write_Value_Select.
Reset the Write_Active bit.
12.2.2.3 Writing bits
In addition to the control bits in bytes 6/7, further bits can be set and, if necessary, reset
directly with Write_Value_Select.
To set bits 80 to 127, the corresponding function number is written to
Write_Value_Select (see Chapter
12.2.5).
To reset bits 80 to 89, the corresponding function number +128 (208 to 217) is written to
Write_Value_Select.
Action of the master Slave reaction
Writing the bit address as a function
number to Write_Value_Select.
The bit from Write_Value_Select is
set and the corresponding function
carried out.
Set the Write_Active bit.
Wait until Write_Active has been set.
Write 0 in Write_Value_Select.
Reset the Write_Active bit.
12.2.2.4 Reading bits
Reading individual bits which are not contained directly in the read window is only
possible with a corresponding function number and the data in Read_Data (Byte 0-3) of
the read window. In those bytes, the bits must be evaluated individually.
The procedure is the same as that described in Chapter
12.2.2.1.
3. Write the function number as Write_Value_Select in byte 5 of the write window (e.g.,
"Basic” application: 190 = analog output 1).
4. Wait until Write_Active = 1 in the read window.
5. Write 0 in byte 5 (Write_Value_Select).
Write_Active is reset.
