Metso locator issue

When must the ROT options cC and ccC be set inside?
During configuration, cC and cCC must be determined based on the relationship between the rotation direction indicated by the valve positioner and the valve’s movement
It seems to be a reverse action; it can be used when inverting the control signal
No matter what choice is made, it doesn’t make any difference; it’s confusing
ROT (Rotation Direction), CC (Clockwise to Close): This setting is determined by the direction in which the valve rotates and its opening/closing behavior. For double-acting positioners, it affects the relationship between the input signal and the valve’s opening degree, that is, the positive and negative actions of the positioner.
