The Digital I/O Input Register 1 (08.072) is always active and shows the value in the Digital I/O State parameter for all digital I/O configured as inputs.
Bits in the Digital I/O Output Register 1 (08.073) can be used to control the digital I/O directly. The bits control the output directly and are not modified
by the corresponding Digital I/O Invert/Toggle function. The bits in the Digital I/O Output Register 1 (08.073) only control the corresponding digital out-
put if all the conditions below are met:
1. The corresponding bit in the Digital I/O Output Enable Register 1 (08.071) must be set to 1.
2. The digital I/O must be an output, or it must be an input/output and the corresponding Digital I/O Output Select parameter must be one.
3. The corresponding Digital I/O Source/Destination parameter is not as valid source (e.g. 0.000) and the drive has been powered-up or reset since
it was first selected.
If the above conditions are not met, the digital output is controlled by the normal logic.
