– Six "high-speed inputs" on Control Unit 320
If these inputs are used, for example, for the "flying measurement" function, they act
as "high-speed inputs" with virtually no time delay when the actual value is saved.
– The properties of the "pure" digital outputs apply.
– The properties of the "pure" digital outputs apply.
