Bidirectional digital inputs/outputs
Signal processing using the bidirectional inputs/outputs is shown in the function diagrams
listed below.
● Can be parameterized as digital input or output.
● When set as digital input:
– Six "high-speed inputs" on Control Unit
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.
● When set as digital output:
– The properties of the "pure" digital outputs apply.
● Sharing of bidirectional input/output resources by the CU and higher-level controller (see
Section "Use of bidirectional inputs/outputs on the CU (Page 969)")
