Virtual instrument control is activated by means of parameter hd.1.
By setting parameters S.In and S.Ou you can enable the writing of some parameters via serial line, set the value of
inputs and the state of outputs.
You have to enable alarm setpoints AL1, ..., AL4 when write operations are continuous, and you don’t have to keep
the last value in eeprom.
Enabling the PV input means being able to exclude the local Tc or RTD acquisition and replace it with the value written
in the register VALUE_F.
Enabling digital input IN lets you set the state of this input, for example to run MAN/AUTO switching with the writing
of bit 7 in the register V_IN_OUT.
Likewise, you can set the on/off state of outputs OUT1, ..., OUT10 and of the LEDs by writing bits in the register
V_IN_OUT.
