Properties
S Can be parameterized as digital input or output.
S When set as digital input:
– Six "high-speed inputs" on Control Unit 320
If these inputs are used, for example, for the "measurement on-the-fly"
function, they act as "high-speed inputs" with virtually no time delay when
the actual value is saved.
– The properties of the "pure" digital inputs apply.
S When set as digital output:
– The properties of the "pure" digital outputs apply.
