Monitoring

4-8
With the monitoring command you can get a selectable actual value of
the process. First select one process value by writing selection number
into register monitor code (RWwm). Second you activate monitoring
with monitor command (RYnC). While this bit is active and the CBL
acknowledges with bit monitoring (RXnC), you get actual values in
register monitoring value (RWrm). You can change the monitor code
during monitoring command is active. But attention, you don't know at
which time you get actual values from the new selected process value!
Better you close the monitoring sequence, change the monitor code
and start a new sequence.
