Instrument Neutral Distributed Interface INDI  2.0.2
Standard Properties - General: Common properties shared across devices of multiple genres.

The following tables describe standard properties pertaining to generic devices. The name of a standard property and its members must be strictly reserved in all drivers. However, it is permissible to change the label element of properties. You can find numerous uses of the standard properties in the INDI library driver repository.

As a general rule of the thumb, the status of properties reflects the command execution result: IPS_OKAY: Command excuted successfully. IPS_BUSY: Command execution under progress. IPS_ALERT: Command execution failed.
