Process data

Incorrect data assignment!
Danger caused by uncontrolled movement of the system.
Always set the unused bits to the value "0".
The valve driver board receives output data from the controller with nominal values for the position
of the valve solenoid coils. The valve driver translates this data into the voltage required to actuate
the valves. The length of the output data is 8 bits. Of these, 4 bits are used with a 2x valve driver
board, 6 bits with a 3x valve driver board, and 8 bits with a 4x valve driver board.
Fig. 4 shows how valve positions are assigned on 2x, 3x, and 4x valve driver boards:
