As an alternative, the process setpoint can be transmitted via bytes 3 and 4 (value
0...1,000), using a process controller (option).Value 1,000 corresponds to the
maximum process setpoint, value 0 to the minimum process setpoint.

Bits 0 – 7 allow the direct selection of 8 intermediate positions via fieldbus commands.
Hereby the selected intermediate position is approached directly, without stopping
in another intermediate position.
In this case, the actuator continues running until the selected intermediate position
has been reached. Example: Operation from position 5 to 7 without stopping at
position 6.
For further information, please refer to the AUMATIC AC 01.2 Profinet manual
(operation and setting).
