3.34. Virtual instrument control
The virtual instrument allows the hardware resources of the
device to be set up from the serial line, writing dedicated
configuration parameters instead of using the normal con-
troller processing flow.
Control of the virtual instrument is activated via the param-
eter hd.1.
By setting the S.In e S.Ou parameters, it is possible to
enable the writing of certain variables from the serial line
and impose the value of the inputs and the status of the
outputs.

Alarm thresholds AL1... must be enabled. AL4 when write
operations are continuous and there is no need to keep the
last value in the EEPROM.
Enabling digital input D1 allows the status of this input to
be set, for example to perform MAN/AUTO switching by
writing bit 10 of the SERIAL_LED register.
Similarly, the ON/OFF state of outputs OUT1...OUT10 and
LEDs can be set by writing bits in the SERIAL_IN_OUT
register.
