9.5 Bit assignment in the process image
Output area of the controller
Each of the three questions has its own output byte. The LEDs are assigned to the bits in the
output area of the controller as follows:
Bit 7
R 7
G 7
B 7
DO 7
R =
G =
B =
DO =
For the output bytes 0 to 2, the bit combinations of the bit x are illustrated in the following
table.
