7.6.3.6 Attribute 0x68, Preset Value
Danger of physical injury and damage to property due to an actual value
jump during execution of the preset adjustment function!
 The preset adjustment function should only be executed when the
measuring system is stationary, or the resulting actual value jump must be
permitted by both the program and the application!
Preset Value is used to set the measuring system value to any position value within the
range of 0 to measuring length in increments –1.
The output position value is set to the Preset value parameter, if the
Set_Attribute_Single service is executed to this attribute.

So that this attribute is saved permanently, 0x70 Accept Parameter must be
performed.
In order to ensure a safe acceptance of the instance attributes
● 0x0C, Direction Counting Toggle
● 0x65, Total Measuring Range
● 0x66, Number of Revolutions - numerator and
● 0x67, Number of Revolutions - divisor
changes must be first taken over by means of 0x70 Accept Parameter. In a
further step the new Preset value can be written. If this value should be saved
permanently, thereafter 0x70 Accept Parameter must be performed.
