Transmission of the event meassages to the bus

Event priority
Event messages are only transmitted to the bus if their priority is between 2 and 15. Events of
priority 1 are indicated on the display but not transmitted to the bus. Events of priority 0 are
ignored. By default, the priority is 0 for all events. The priority can be adjusted individually for
each allocation parameter. This is done by the following four priority parameters:
Suppression of individual events
For individual events, the transmission to the bus can suppressed by the use of a mask. The
corresponding events will be displayed but not transmitted to the bus. In FieldCare, this mask can
be found at Expert ® Communication ® Field diagnostics ® Alarm broadcast enable.
This mask functions as a negative mask, which means that, if a field is marked, the corresponding
events will not be transmitted to the bus.

changes
