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 Manual (operation and setting)AUMATIC
AC 01.2 Modbus.
If the multiport valve function is active (option), the entire byte 6 is used for coding
of multiport valve operation commands. Up to 12 positions can either be approached
selecting the shortest path, in clockwise direction (CW), or in counterclockwise
direction (CCW). Furthermore, the actuator can also be operated without any position
indications (CW or CCW).
