Note: The 12 logs must be written at once (as a group), otherwise it will respond with an error.
6�3�9�- QUALITY EVENTS ALARM FLAG
Function 0x04 is implemented for these variables: reading logs.
This variable indicates whether a quality event has occurred or not and activates a 10-second
ag on the bit describing the event.
