Depending on the data point type, the following default values apply if all priorities
are released (that is, no software component accesses this channel):
Type of data point
Default value
Digital output – output signal
off
Analog output – output signal
0.0 V
DALI control - ballast
0.0 %
Analog input – measurement range 0..10 V, if applicable
Table 4.6.3:
Default values of priority control
Some actions have command character. These do not change the priority level, but
are processed in their order of occurrence (or suppressed completely in case of
insufficient priority). Such commands are:
Initialization of counter values of the pulse metering terminal
DALI lighting control commands
Initialization, read and write operations of serial terminals
For these cases it is up to the application programmer to prevent unwanted
concurrent accesses from different sources.
