Byte 6: Intermediate positions
Byte 6 is used for coding operation commands. Thus, 8 intermediate positions can
be directly selected 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.

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 travel, in clockwise direction (CW), or in counterclockwise
direction (CCW). Furthermore, the actuator can also be operated without any position
indications in clockwise or counterclockwise direction (CW or CCW).
